Every car enthusiast would like to receive, but for some reason does not know who to ask them to or is afraid to ask the auto mechanic for them. Unfortunately, for this reason a large number of questions that worry drivers remain unanswered. offers you answers to the most popular questions that bother many drivers.
"How does it work diesel engine? ", "What is the difference between a supercharger and a turbocharger? ", "Can I use low octane fuel? ?" And many other questions worries a lot of motorists. But on different reasons, people tend to be afraid to ask such questions to auto mechanics, embarrassed by their incompetence. Familiar? Surely you are worried about something that you want to get an answer to. We hope our most popular questions on automotive topics will be useful to you.
10) Should I use high octane gasoline in my car?
No, you do not have to pour into a car with a high octane rating. However, if the manual for vehicle Since the car manufacturer recommends using at least a certain octane rating, we recommend that you follow the advice of the car company. But if from time to time you
If your car is designed to use high-octane fuel (for example, AI-98), then, as a rule, your power unit has a higher compression ratio compared to engines using lower-octane gasoline (AI-92 or AI-95). Also, the engine, which is designed to run on high-octane gasoline, has an advanced ignition system.
But do not be afraid that low-octane gasoline will damage the engine.
Thanks to the development automotive technology, All modern machines electronically controlled (including engine operation). Therefore, if you fill up with low-octane fuel, electronic system injection will independently adjust the engine to the optimum level, without damage to the main systems power unit. The maximum that awaits you is a small loss of power. It is noteworthy that a low-octane fill in your car may reduce fuel consumption.
If your car is powerful enough, then most likely you will not even notice the difference in the performance of the car if you fill it with gasoline with a lower octane number.
9) Why does the turn signal blink faster if the bulb in the other burns out?
In fact, science explains everything very simply! The thing is that the work of the turn signals is controlled by electrical relay which turns the light on and off. When one turn signal starts flashing faster and the other does not work, this is due to the fact that a light bulb has burned out in one turn signal. The thing is that due to the burnt out light bulb, the voltage in the network has dropped.
With less load on electrical circuit, work is facilitated for the relay, which begins to perform its function much faster.
8) Can the motor rotate in the reverse direction?
Many have probably wondered if the engine can rotate in the other direction? This issue is especially worrisome for those who know that the starter can rotate in different directions.
We answer. Only a two-stroke engine can reverse. Unfortunately, a four-stroke motor spins in reverse side can not. So what if your garage has old car Trabant, then you can try to start the engine in the opposite direction.
7) What is the difference between a turbocharger and a supercharger?
Many motorists know that both accelerators perform approximately the same role during operation. But what is the difference in their design and operation?
Both devices, by compressing and supplying air under pressure to the engine, allow the engine to burn more fuel, which gives the power unit more power. The difference is in the principle of operation of these superchargers.
The supercharger pump is connected directly to the engine (usually by means of a belt drive). This means that than more revs engine, the greater the level of compression and air supply to the combustion chamber. But, unfortunately, in order to achieve maximum power, it is necessary to wait until the engine speed is maximized. The disadvantage of this compressor system is that at low engine speeds, the air compression will not be large, resulting in maximum power motor will not be available to you until you spin the engine up to high speeds.
Hydraulic controller (control unit) this is the most difficult part of the whole automatic transmission. As a rule, an automatic transmission has a pump (or several pumps) that regulates the pressure on input shaft boxes. There is also a valve (or pump) on the output shaft, which also regulates the pressure in the box.
Due to the differences in pressure, a logical chain of gear changes is created depending on the engine torque. This work is assisted by various valves that activate the inclusion of a particular gear, using shift levers that control planetary gear boxes.
At present, the mechanical parts of automatic box have been replaced by computers. In modern automatic transmissions, electronics control the transmission, determining on its own when to shift gears.
1) How do engine pistons transmit smooth torque?
For this, on the one hand crankshaft, to which the energy of the piston stroke is transferred, a flywheel is fixed. Thanks to the flywheel, the engine runs balanced and without unnecessary detonation. Otherwise, the vibration from the pistons would be transmitted throughout the car body.
So with a slight shift of the pistons, the flywheel stands still (does not rotate). Rotation begins after the pistons make a certain ( set stroke). Even if you press the gas pedal to the floor, the flywheel will rotate a little slower than the power unit. Thus, this important part of the car transmits a balanced torque to the gearbox without jerking and detonation.
How more cylinders in the motor, the easier it is to balance the operation of the motor, using fewer special balancing weights. But regardless of the number of cylinders in engines, the flywheel is still used in modern cars for smooth transmission torque.

Answer from Alexander[guru]
Like only sports cars(or with a claim to sportiness). IN this case this implies - a spartan interior, high dynamics, extraction of all the "juices" from 1 liter of fuel, manual transmission, rear drive and, of course, design (aerodynamics). But this is ideal... I would love to purchase road version any car, regardless of the price. But what I really appreciate about retro cars (especially from the 60s) - apart from all the merits modern cars they have charm... These are masterpieces created by the brush of real masters, they have what a person has - a soul!. . And when you press the gas pedal to the floor, you feel this music ... SOUL and HEART of the car. In addition, the price of such cars is not small, and this is already saying something ...

The car has long ceased to be a luxury item. Today, almost everyone can afford to buy a personal transport. But there are connoisseurs who do not need cars mass production. What do true connoisseurs appreciate in a car, of which there are not so few in the world?
Core values in a machine for connoisseurs
If a person has been engaged in cars for a long time, drives a car or closely follows the latest in the automotive industry, over time he moves into the category of connoisseurs who appreciate in the car:
- Speed. The faster the car goes, the more money is invested in it. A car with an average or weak engine will not be able to develop a breakneck speed, which means it will not be of interest to connoisseurs.
- Engine. The more horsepower, the faster auto will drive, which means that acceleration to 100 km or more will take a matter of seconds.
- Mark. The more expensive and respectable the brand of car, the more labor and good parts. Agree, a car with 500 horsepower certainly will not cost 100,000 rubles. Otherwise, it would become accessible to the majority, which is not interesting for connoisseurs. A prestigious car brand, regardless of the year of its release, will always attract connoisseurs, however, as will its cost.
- Salon. Expensive interior does not leave anyone indifferent. Leather combined with wood strikes the heart of even the most uninterested person in cars. The more money invested in interior design, the higher the price of the car. Some cars are plain in appearance, inside - just a feast for the eyes. Connoisseurs understand these cars better than the layman.
- Number of owners. If the vehicle had, for example, 5 owners, then the car is unlikely to be in good condition. A good car should have one owner who, after buying it in a car dealership, will follow it like a girlfriend.
One more important detail that real connoisseurs appreciate in a car is the ergonomics of the steering wheel. This is especially true for those vehicles that have to travel a large amount of time. If the steering wheel is uncomfortable for the driver, then it is unlikely that such a car will be appreciated by real connoisseurs.
