What is better to use: gas or gasoline? Which is better: gasoline or gas.

19.04.2019

The gas engine is designed not only for oversized vehicles, it is quite suitable for a passenger car, because any combustible mixture, in fact, one way or another will make the motor work. This is especially attractive when comparing prices - gas is two times cheaper than gasoline! A fair question arises, why, then, car owners do not switch to such an economical type of fuel, but gas station owners still not broke? Because every phenomenon has flip side which is not always attractive. Before switching the car to gas, it is worth considering two parameters: economic and technical. The first aspect is easy to calculate using a conventional calculator, you just need to know a few basic numbers. For example, a car consumes 12 liters of fuel for every 100 km, this is an average of 1.6 liters. With the cost of 92nd gasoline of 20 rubles per liter, you will have to pay 10 for gas. Study the prices in the region for LPG, which are individual for each car, along with installation. Alternatively, 10,000 rubles. Now calculate average annual mileage, let 30,000 km. Now make the calculations: 30,000/100 x 12 \u003d 3,600 liters of gasoline, which, with an initial cost of 20 rubles per liter, will total 72,000 rubles. Gas consumption for the same run will be 36,000 rubles, that is, two times less. The octane number of the gas is 103-105, which almost completely eliminates detonation and the negative phenomena caused by it. Due to the better mixture formation of gas with air and the fact that the gas mixture is more evenly distributed over the cylinder, it improves idling engine, it runs quieter and smoother. Gas does not liquefy engine oil, when it is burned, almost two times less CO is formed. However, each setup has disadvantages, gas engine not an exception. Gasoline has a higher calorific value. 1.19 liters of gas is equivalent to a liter of gasoline. Hence the higher fuel consumption. Petrol engine by 5%. Inexpensive gear HBO except for a certain optimal mode engine operation constantly either slightly leans or re-enriches the mixture. Such thermal overloads have to be experienced by spark plugs, valves and their seats in the cylinder head during high-g driving, driving in mountainous terrain, thus gas is not for racers. Can't be installed on every car. gas cylinder due to bulkiness: than more modern car, the more expensive and more difficult the GO on it. If it is easy and inexpensive to install gas in an old carburetor vehicle, a modern computer-controlled injection engine requires flashing controllers, tie-in nozzles and other difficult and expensive operations. Gas equipment is completely unsuitable for installation in small cars, with an annual mileage of less than 10,000 km. It is not recommended to install it on cars that are less than a year old, on cars with a diesel engine and, of course, if locality no gas.

Cars that run on gasoline, if desired, can be supplemented with gas-cylinder equipment. However, one should not make such decisions hastily: both gas and gasoline have their drawbacks and advantages, which should be taken into account in each specific situation.

The main advantage of gas that attracts car owners is the relatively low cost. The difference is especially noticeable if the car needs expensive high-octane gasoline and "eats" a lot of fuel. In this case, by installing gas equipment, you can significantly reduce costs. On the other hand, do not forget that the gas equipment itself, as well as its installation, require money. Installing cheap low-quality devices is not only pointless and unprofitable, but also very dangerous, since poor equipment and improper installation can eventually cause a fire. Quality devices are quite expensive. This means that at first there will be no talk of any savings, so it makes sense to install gas equipment to save money only on the condition that you drive very often and a lot. Otherwise, it will not pay off soon. Gas has another advantage: it is more environmentally friendly than gasoline. A car that runs on gas emits much less harmful substances than a car that uses gasoline as fuel. By the way, this helps to extend the life of some parts of the car, including the combustion chamber. On average, cars running on gas drive without repairs 1.5-2 times longer than gasoline ones. But at the same time, it is important to remember that gas equipment requires careful handling and, if used improperly, can simply explode. The gas mixture burns more slowly than gasoline, but it is processed almost without residue. As a result, the engine starts to run quieter, and the spark plugs do not get dirty for a very long time. However, this also affects the characteristics of the car: it accelerates more slowly and loses some power. In addition, in cold weather, you simply won’t start a car without using a gasoline engine. Thus, it is more profitable to drive on gas if the car requires high-octane gasoline, the car is used very often (moreover, mainly in the warm season), and you handle it quite carefully.

Tip 3: Which engine is better: diesel or gasoline

When buying a new car, many people have a question, which engine to choose: diesel or gasoline? In Europe, the first type of motors is quite popular, but not very much in Russia. For many, it is associated with smoky trucks and tractors, but not with new foreign car. On the other hand, looking at the current fuel prices, one has to think about how and on what to save. If you believe the data of car dealerships about official expenses fuel of two engines, in terms of economy, diesel is more profitable.

Instruction

According to statistics, in Russia, a gasoline engine is available in 2/3 of cars. Several factors play in its favor:
- cars with this engine are cheaper diesel cars by about 10-15%;
- some car manufacturers do not supply domestic market cars that run on diesel fuel;
- a familiar association for many: a car - gasoline.

In addition, at gasoline engines there are other benefits as well. They weigh less, give out more power, do not make noise, but in hard frost start without any problems. But they also have significant drawbacks: a higher price per liter and fuel consumption.

Concerning diesel engines, at first glance, everything is fine here. A liter of diesel is cheaper than gasoline, fuel consumption is less. In addition, new vehicles with such engines are not subject to the new duties. However, diesel engines are very demanding on fuel quality. The quality of domestic diesel fuel is often low, and therefore it is safe to say that you cannot avoid problems with fuel. Trips to the service to pass scheduled maintenance will be more frequent, and it will also cost a little more than for cars with gasoline unit.

Next important point concerns security. Diesel fuel is non-volatile (that is, it does not evaporate easily). That's why
The risk of fire in diesel engines is much lower, especially since they do not use an ignition system.

So which engine - diesel or gasoline - still give preference when buying new car? There is no definite answer here. You have to look at the situation. So, if you buy a car only for commuting to and from work, knowing that after a few years you will sell it, you should opt for a gasoline engine. Initially, such a car will cost less than a similar one with a diesel engine.

If you plan to travel by car all the time and your annual mileage will exceed 30 thousand kilometers, it is better to give preference to a diesel engine. The lower cost of refueling, moderate engine appetites will allow you to quickly compensate for the initial overpayment for a car and maintenance. So, which engine is more suitable for your needs, it's up to you. However, approach this choice responsibly. Ask managers, take cars for a test drive, and then your choice will bring you joy and pleasure.

Methanol is the new gasoline

The principle of obtaining methanol from natural gas is that the gas at elevated temperature gives a reaction to water vapor and catalysts, as a result of which the so-called "synthesis gas" is first formed, from which, in turn, is formed.

Studies show that methyl alcohol can be used as a high-octane additive to regular gasoline. In addition, methanol can be used as a fuel and by itself - it octane number is 115.

The car engine, which is filled with methyl alcohol instead of gasoline, lasts much longer. At the same time, only by replacing one type of fuel with another, engine power is automatically increased by 20%. There are no harmful impurities in the exhaust gases of a car running on methyl alcohol.

Getting alcohol from gas

An apparatus for producing methanol from natural gas can be designed independently. It consists of two tubes - one of them is connected to a cold water tap, the other to a source of natural gas (or a cylinder). The ends of both tubes enter the mixer, in which the mixture of gas and water vapor is heated by a burner to a temperature of about 100-120 degrees. From the mixer, the gas-water mixture enters the reactor filled with a catalyst. The catalyst is 25% nickel and 75% aluminium. In the reactor under the action high temperature(about 500 degrees) and a catalyst from a gas-water mixture, synthesis gas is formed, consisting of hydrogen and carbon monoxide.

Next, hot synthesis gas enters the refrigerator, where it is cooled to a temperature of 35-40 degrees and enters the compressor, where it is compressed to a pressure of several atmospheres. At the next stage, the synthesis gas enters the second reactor filled with a catalyst consisting of a mixture of 20% zinc and 80% copper. Here, at a temperature of 270 degrees, methanol is formed from synthesis gas, which is then condensed in a refrigerator and drained into a container.

According to people experimenting with making methanol from natural gas, about 3-5 liters of methanol per hour can be produced under conditions. At the same time, the cost of such fuel is a few.

Attention!

Remember that methanol is a poison. Its vapors are flammable. The slightest leak of natural gas from a gas stove or methanol machine can cause an explosion.

Traditionally, cars run on gasoline, but due to its cost and limited natural resources, drivers are increasingly switching to gas. To understand whether it is worth doing this, you need to know: gas or gasoline, which is better and what disadvantages are hidden in them.

What to Consider

When buying a car, a person chooses it based on his preferences: spaciousness, cross-country ability, design and power. But not everyone pays attention to which will be used. In turn, this indicator affects not only the price, but also the behavior of the car on the road.

As a rule, cars with petrol or diesel engine. Gas installations are extremely rare in transport as the main system. They were created much earlier than the gasoline engine, but received recognition only in our time.

Important liquid

Almost every car owner knows the benefits of gasoline. And the design of such an engine is considered most often. Because of this, it is not difficult to deal with breakdowns that occur during operation. Also a big advantage is the presence a large number filling stations.

In the event of a breakdown, it will not be difficult to find the nearest service. Repair is quite simple. If you choose which is better, gas or gasoline for a car, the second option is widespread and easy to maintain. Somebody think gasoline engines more dangerous, but this is observed only with the installation of low-quality HBO.

Why is he worse?

One of the most significant shortcomings gasoline is considered its value. Every year it continues to grow, and this does not depend on the dollar or the economic situation of countries. As natural resources are depleted, the trend will continue. Also, at many gas stations, poor-quality work can be observed when foreign substances are mixed into the fuel, which significantly reduce the characteristics of gasoline.

The environment also suffers from gasoline engines, because traffic fumes severely harm nature. For this there are special installations or hybrid models, but they still have a detrimental effect on the planet, releasing fumes.

Gas use

The gas is by-product which is produced during oil refining. It is of great interest to many motorists, because it has a noticeable cheapness. This is also complemented by a reduced capacity of carbon monoxide, due to which environmental damage is significantly reduced.

According to statistics, running cars break down much less frequently than those using standard fuel. It has also been proven that the overall wear of mechanisms is reduced by 15% and their corrosion is almost completely eliminated.

The advantages of alternative fuels are especially noticeable in summer time when gasoline under the influence of high temperature is able to warm up, causing big problems the whole car. The gas stably keeps its temperature indicators.

Types and methods

Having expressed a desire to go to gas fuel, it is worth considering the choice of cylinders. In practice, they are classified into toroidal and cylindrical. The choice depends on the individual characteristics of the machine. Cylindrical have an elongated shape and are installed behind the passenger seats. In some cases, they can be mounted under the bottom of the transport. Toroidal - outwardly resemble a spare wheel and are put in its place without taking up extra space.

Is everything so good?

Despite all the advantages, the installation gas equipment will cost a lot of money. Moreover, this will lead to a reduction free space inside the car or trunk - the gas cylinder is quite large. True, it will not be possible to completely forget about gasoline. It will remain necessary when it is required to warm up the vehicle and start it. During the winter period, it will not be possible to do without it at all.

It is also often difficult to replenish gas reserves, because specialized gas stations are mainly located outside the city. In addition, this type of fuel reduces the performance of the car and its speed. Thus, 7% of the productive movement is lost. This disadvantage is compensated by the ability to regulate gas compression.

Serious problem

As many motorists note, when comparing gas or gasoline, the pros and cons, in the first case, a “reverse cotton” effect may occur. It looks like a small explosion that can cause significant damage. vehicle. Such a disadvantage is also observed with a gasoline-powered engine, but in it it does not do much harm (maximum - torn air filter).

Reverse cotton occurs quite rarely. It can be prevented by monitoring the performance of the gas-cylinder system. To do this, you need to conduct a regular inspection of the car and refuel it only.

Today there is no definite position - to continue to use gasoline or switch to gas? Such a decision depends only on the owner of the car, who is willing to save money or trust a proven option.

For those who regularly use the car, refueling becomes big problem. Gas is considered much cheaper, but its use requires serious processing of the machine. Such a system should only be installed if sufficient space and resources are available.

Cars, as you know, run on fuel. Despite the fact that most of all cars in the world, in recent years, more and more car owners are switching to gas. Which is better - gas or gasoline - we will try to find out.

The gasoline engine was created at the end of the 19th century by the German designer Gottlieb Daimler. However, it appeared even earlier. It’s just that it received its distribution only in our days, since it was completely superseded by the gasoline engine that appeared later.

Essential Liquid

The popularity of gasoline last years dropped slightly. And there are good reasons for this: the quality of fuel and its cost. If in Soviet times it was quite difficult to get irreplaceable fuel, then no one tried to judge the quality: the cars ran like clockwork, and the drivers could not get enough of the agility of their “iron comrade”. Today, everything happens according to an absolutely opposite scenario: it is not difficult to refuel a car, only the quality of the fuel leaves much to be desired. By itself, gasoline is a liquid fuel that is obtained by distilling oil. But as the results of the examination show, practically at all gas stations in gasoline, thus reducing its quality.

Another one back side medals - the price of fuel. Every year it only increases, regardless of the exchange rate of the American currency or domestic political events in the state. These price increases largely determine the fuel choice of car owners today.

The disadvantages also include a high concentration of carbon monoxide, which is bad for the condition environment and the health of mankind.

However, gasoline also has positive aspects. As already mentioned, gas stations are located everywhere, which means that you can buy gasoline without obstacles. It is also much less than gas consumption. This is due to the liquid state, due to which the manufacturing costs fuel mixture noticeably less. Also, the advantage of gasoline is the presence in cars of gasoline engines that are completely tuned for this type of fuel. And the power of the engine when using gasoline is much higher than on gas. Well, add here the slight possibility of lubricating the cylinders with gasoline from the inside when it is injected just before ignition.

The video shows how to refuel a car on gas:

And we have gas in the car! And you?

Gas ( gaseous substance) is a by-product obtained from oil refining. More often the car is filled with methane or propane-butane. Gas is used mainly because of the economy, because at least twice for gasoline. This is a more environmentally friendly type of fuel, since the concentration of carbon monoxide in it is much lower than in gasoline. Accordingly, it is less dangerous for the environment.

As test results show, cars operating on gas do without repairs one and a half to two times longer than gasoline counterparts, which reduces engine wear by fifteen percent. In addition, the efficiency is almost doubled due to the almost complete absence of corrosion of metals.

Besides, power unit on gas, it overheats much less than its twin on gasoline, which significantly saves the owner of the car from troubles and additional worries.

However negative sides this product also has. The most important thing is the expensive installation of the appropriate equipment on the car, part of which (namely the gas cylinder) will also take away the free space or trunk of the car.

When installing gas equipment, it is impossible to completely refuse gasoline: only gasoline can warm up and start the car in the morning, and you can’t do without it at all.

The video tells about the effect of gas on a car engine:

Filling up a car with gas is not so easy, because gas stations are located outside the city for safety reasons.

Another disadvantage of using gas is a certain decrease in the acceleration dynamics of the car and its decrease by about seven to eight percent. But this is not such a serious issue, because the dynamics of acceleration is easily regulated by changing the level of gas compression. Just remember: this adjustment takes place only in the current gas supply systems, and not in carburetor engines.

In addition, in an engine that operates on gas, the occurrence of "reverse cotton" is quite possible. In fact, it is an explosion. In a gasoline engine, such a process is also possible, only the consequences will be much less serious, take at least a torn air filter. In general, "reverse cotton" is a rather rare phenomenon, but in order to avoid it altogether, careful control is necessary when using gas equipment. Remember: it is good working condition ignition systems.

What to choose

There is still no definite position regarding the choice. Some prefer diesel, others prefer familiar and familiar gasoline, while others switch to gas. There is a single rule here: everyone chooses what he likes and can afford. Despite the usual gasoline for many, many car owners decide to switch to gas. First of all, this is due to economic benefits, because the cost of gas is several times less than the price of gasoline. And this is even taking into account the higher consumption of gas compared to gasoline.

Comparing all the facts and analyzing all aspects of this issue, you yourself will choose gasoline or gas for your "iron horse".

Today we will talk about gas and gasoline and what is better for the engine.

With petrol prices on the rise, many car enthusiasts are already starting to think about converting their car to gas.

Indeed, some enjoy such a privilege, and it has appeared for more than a decade.

But there are still myths and disputes that contradict each other.

Let's see what pros and cons the driver will expect if he starts refueling with gas?

Gas - pluses

Undoubted advantages of such a translation.

Price.

Quite low compared to gasoline. Gas is cheaper than gasoline by more than 30%.

Even if the car consumes gas more than gasoline by 30% and if you add the cost of installing equipment, you can still recoup all costs in a few years.

This option is especially good for those who drive very often. The use of this fuel can be reduced.

This is done only by professionals. They regulate gas equipment.

With gas, the exhaust is the least toxic. It is, of course, cleaner than gasoline, and three times. And consequently less damage to the environment.

Engine safety.

It wears out less in this case because the engine runs quieter and softer.

When gaseous fuels are burned, there will be much less ash, as well as particulate matter and soot.

Thanks to all this, cylinders and pistons will last much longer. And also, you will no longer need to pay a lot of money for expensive cleaning or.

Oil saving.

Engine oil will not deteriorate as quickly, so you will need to change it much less often.

No need for frequent refueling. The car will increase mileage several times without refueling, because you will use two fuel systems.

Efficiency.

The most effective HBO latest generations, fifth, sixth. Less effective, but the most common and relatively inexpensive.

It is transitional between 2 - m and 4 - m and is now rarely used, of all the above HBO, it is the least effective.

It was mounted on the first injection machines, and usually installed on its own.

Summing up

What better gas or gasoline is an eternally sore point for motorists. On one side of the scale are: cheaper gas, lower emissions, better engine safety and lower oil consumption.

On the other hand, you need to understand that gas consumption is greater than gasoline, and therefore the payback on the purchase and installation of LPG will stretch even more in time and take more than one month or year, everything will depend on how much time you spend behind the wheel.

It is possible to convert the car to run on gas as fuel. Is it really worth doing it and why gas better gasoline and (diesel)?

Let's figure it out. Should I install gas on the car or leave it on gasoline?

To appreciate the benefits of running a car on gas, both for the motorist himself and for the internal combustion engine, it is necessary to understand the very "physics of the process".

Consider the physico-chemical properties of fuel: propane, butane, gasoline and diesel.

As can be seen from the table, the physicochemical properties different types fuels are significantly different, which determines the difference in the degree of impact on the engine and performance characteristics car.

Let's consider in more detail.

Safety: Let's compare gas and gasoline

Both gasoline and gas and the car itself are sources of heightened danger. This means that it happens that they burn when certain conditions occur (impact, accident, fire, etc.).

In such conditions, we can only talk about the relative safety of all types of fuel.

The safest among the considered types of fuel is gas.

This is due to the wider ignition limits of gas compared to gasoline. The flammability limit is the boundary values \u200b\u200bcharacteristic of a particular type of fuel at which spontaneous combustion of the mixture is possible when certain proportions of the gas or gasoline mixture come into contact with air.

As mentioned earlier, everything burns, however, gasoline and diesel start burning already at a temperature of about 250 degrees, while the ignition temperature of gas is about 550 degrees (!).

In the event of a significant leak (in an emergency), gasoline will ignite faster than gas, since it needs less air to ignite. Gas flammability limits: propane-butane mixture - 8.4-9.9% gas in air, lower limit 1.8-2.4%. The ignition limits of gasoline mixed with air are 0.6-1.5%, respectively. Thus, the ignition limits of gas are 15-20% higher compared to gasoline.

Gas is the undisputed leader in terms of safety, based on its physical and chemical properties.

About additional modern systems protection of gas-balloon equipment installed on a car, such as a multi-valve, high-speed valve, safety valve, which bleeds the gas out and protects the cylinder from destruction - see HBO

It is important to note that such modern means protection petrol system simply does not have.

The effect of gas on the engine

Gas or gasoline: which is better for the motor? Now let's figure it out.

Octane number (OC): The higher the octane number, the less detonation effect on the engine.

Gas has an octane rating much higher than gasoline. This allows you to save the engine from knocking and increase its power by increasing the compression ratio of the engine.

In contrast to the processes of combustion of a gasoline mixture, gas has more complete combustion gas-air mixture. Due to this, the existing oil film on the cylinders (which serves to protect them) is not washed off the engine walls, and the formation of soot in the block is also reduced, which together reduces the wear of the engine cylinders and pistons.

When a car engine switches from liquid fuel to gas, the service life of the engine increases by 1.5-2 times (according to studies of gas use in automotive industry performed by VNIIGAZ, see the book: “ Natural gas motor fuel on transport”, authors I. Grishchenko, Yu. N. Vasiliev, F. G. Gainullin, L. S. Zolotarevsky).

In fact, the car engine has a "second life". This is the answer to the question: "What is better for the engine: gas or gasoline?"

By the way, when the car is running on gas, the oil “dilutes” and becomes less polluted, which allows you to change it less often, and the oil consumption itself “for waste” is reduced by an average of 15%. The service life of spark plugs is increased by 40% (up to 85 thousand km).

Gas Ecological: Celebrate 20 New Holidays

Gas is a more environmentally friendly type of fuel.

Propane, butane and methane do not contain lead in their composition, unlike gasoline, which makes car exhaust cleaner. In addition, in cars running on gas, the total toxicity of exhaust harmful gases (carbon monoxide, nitrogen dioxide, CH hydrocarbons, etc.) is reduced by up to 90%.

That is why, in the life of motorists who have converted their car to gas, more holidays appear: World Environment Day and Ecologist's Day and World Oceans Day and International Day for Biological Diversity and more than 20 reasons for joy a year :)

If you love holidays more than weekdays, then it is obvious that in the question “what is better gas or gasoline?” - you are "for" gas!

Profitability: consumption of gas and gasoline

In terms of fuel efficiency, gas is superior to gasoline and diesel.

As mentioned earlier, the octane number is higher in gas, which increases the compression ratio of the engine and can significantly reduce fuel consumption.

The price of gas in Russia is 2.5 times lower than the retail price of gasoline.

Let's compare the cost of gas and gasoline (based on 300 km per week):

Total: travel and work trips for gas car equipped with HBO will cost at least three times cheaper!

happiness in gas

Obviously, gas is better than gasoline for a car.

Once you start saving on fuel, you rejoice.

Less load, cleaner work - your car's engine will enjoy working on gas.

Cleaner air around - nature and neighbors under the windows, whom you "warm up" your car - will say "thank you".

And when everything is good around, your loved ones have joy, then you are happy too.

That's why happiness is in the gas!

According to statistics, the majority (more than 90%) of those who previously owned a gas-powered car install HBO on all their subsequent cars.
