In order to install gas equipment on your "iron horse" you do not need to contact a specialist or have special knowledge. It is enough to follow certain rules. But, be extremely careful. If something goes wrong, you can harm yourself and others.
Re-equipment of a passenger carburetor car costs about $ 100 in the service station. Agree, this is not a small figure, especially for those who are going to equip HBO on the VAZ 2101. Therefore, it is much more profitable to install it yourself and get the relevant documents required to enter information on the presence of HBO in the car's registration documents.
Purchase of equipment
HBO equipment can be found in any automotive market. On average, it will cost $ 250. This includes:
Vacuum reducer;
- a cylindrical cylinder with a multi-valve (for cars, the volume is not more than 50 liters);
- mixer;
- gas and petrol valve;
- filling valve;
- clamps;
- HBO control panel;
- pipelines;
- tees.
Pay special attention to pipelines. A gas leak will not only lead to unnecessary costs, but also to a possible fire. Recall that in the previous article we told with our own hands.
Do-it-yourself HBO installation on a VAZ 2101 - recommendations
1. The reducer must be placed close to the carburetor with a longitudinal arrangement. If possible, place the reducer under the upper pipe of the stove, so the liquid will circulate efficiently in the reducer.
2. The petrol solenoid valve is placed near the brake cylinder by cutting into the petrol pump hose. So, with a possible head-on collision, the likelihood that the valve will be hit is extremely small.
3. When installing the faucet, use gaskets and sealant. This is especially true for older cars. So that the mixer gasket does not burn out, the planes of the mixer and the carburetor in the places where they contact need to be ground.
4. Use plastic piping.
You can install gas equipment (HBO) on a VAZ 2101 car with your own hands, the main thing is to adhere to all installation points, because your life and the lives of those around you depend on it.
Familiarization.
At the car market or from LPG installers, you buy a set of gas-balloon equipment with all components, and then go to our website and see the instructions for installing LPG with your own hands. After installing the equipment, you go to the same HBO installers, and for a fee of $ 25-35 they check the correct installation, if necessary, help set up and issue the documents required to enter information on the presence of gas-balloon equipment into the technical passport of the machine. Savings on re-equipment of a carbureted car is $ 50-80. For owners of old equipment, this is a rather large amount!
$250 per set.
The theory is good, but how do you install equipment on a carbureted car on your own in practice? Having two diplomas in automotive engineering and experience in operating a car with LPG, I decided to check for myself how realistic this is and if there are any difficulties. Friends offered to take their VAZ-21011 with a 1.3-liter engine as a test subject. There is a car, now you need equipment. I found it at one of the metropolitan car markets. The $250 kit included a Lovato Aspirato vacuum reducer (according to experts, it runs 150-180 thousand km, and a repair kit costs $15-20), a 50-liter cylindrical cylinder with a Tomasetto multivalve, cylinder clamps, a mixer (popularly - mixer), filling valve, gas supply tee to the carburetor, gas valve, gasoline valve, pipelines for liquefied gas, for gas in the vapor fraction (diameter 19 mm), for gasoline, for antifreeze water (diameter 19 mm), two tees for connections to the cooling system, clamps for clamping pipelines, a corrugated sleeve and plastic flanges for pipelines coming from the multivalve under the bottom of the car, as well as a HBO control panel. Only special pipelines should be installed, otherwise you can get gas and antifreeze leaks. Since there are no guarantees on the market, it is better to take Lovato or Tomasetto nodes - they are very reliable.
We entrusted the adjustment to specialists, who then issued us documents for the registration of HBO in the data sheet. It took a whole day to install the HBO. By the way, it is advisable to do this with an assistant. Another day was spent on adjustments and obtaining a new registration certificate in MREO.
A new air filter, working spark plugs and high-voltage wires are required to properly configure the HBO. You also need to make sure that there is good compression in the cylinders and that there are no air leaks in the intake tract. Otherwise, you will not be able to set up HBO!
The growing popularity of gas-balloon equipment (LPG) of cars is associated with an increase in prices for more traditional fuels: gasoline and diesel. The relatively low cost of gas can significantly reduce the cost of operating a car. This question is most relevant for those who use cars daily.
The installation of HBO can only be carried out by specialized enterprises that have a license to carry out work of this nature. That is why it is strongly not recommended to independently perform such a transformation of the machine, if you have not had to deal with it at all before.
The instruction below was created on the basis of data from specialists and is not a direct guide to action, carefully weigh your strengths and skills before deciding to install HBO!
detailed instructions
For the successful installation of HBO on the VAZ 2109, a difficult job must be done:
Filling outlet
- Install supply piping. This process is more convenient to perform when the car is on a lift, since the supply line will be located under the bottom. In this case, it is necessary to ensure that the pipes are laid along the side members and away from the moving elements of the suspension system.
- Install the gas valve under the hood, first making sure the quality of its filter.
- Choose the right place to install the gas reducer. To provide the gearbox heating system with an optimal supply of antifreeze, it is necessary to place it just above the engine cylinder head.
- Install the gas reducer.
- Next, you need to embed two tees into the hoses going to the heater radiator. To do this, drain the antifreeze from the cooling system, put hoses of the appropriate diameter on the tees and lead them to the gearbox, where they should be connected to the heating system. After that, you can back fill the entire system with antifreeze and you should definitely make sure that there are no leaks.
If necessary, leaking places will have to be sealed.
- Connect the gas valve and reducer with a high-pressure line.
- A gas aerator should be installed in the car's air filter.
It is worth noting that the mixing gasket on the carburetor is not suitable in the case of the VAZ 2109.
- The installed aerator must be connected to the reducer outlet with a suitable rubber hose resistant to liquids such as gasoline and oil.
- This hose should be cut in any convenient place and inserted into the resulting cut of the dispenser valve. To pre-set the system, the valve must first be completely unscrewed and screwed back by about a third.
- Cut the gas line in the section from the carburetor to the gas pump and install a special valve there, which then needs to be switched to manual control and set to the closed position.
- Install a rocker switch in any free place on the instrument panel. It must be in a neutral position.
rocker switch
- Only through the fuse, one end of the 15 A wire must be connected to the central contact of the switch, and the other must be brought to the ignition switch and soldered to terminal 15 (the blue wire can be with or without a black stripe).
- One wire should be connected to the remaining two contacts, which then need to be brought to the engine compartment, where they should be connected, respectively, to the gas and gasoline valves.
- The free contacts of the gas and petrol valves must be connected to ground.
For this, absolutely any place is suitable.
- You should turn on the ignition and check if the valves responsible for the supply of gas and gasoline are working. Checking is done by changing the positions of the rocker switch. In the neutral position, both valves should be off.
- If the cylinder is empty, you will need to open the filling valve, fill in about 10 liters of gas and close it.
Regulator
- Open the flow valve and check the tightness of the connections of the high-pressure fittings using an ordinary soapy solution. Tighten the connecting fittings if necessary. If this does not give any result, that is, the gas leak does not stop, you need to close the flow valve, release the gas from the pipeline and seal the connections using the FUM tape.
- Start the car on gasoline - move the rocker switch to the appropriate position and manually prime the fuel.
- After warming up the VAZ 2109, open the gas cylinder supply valve, move the rocker switch to the neutral position and work out the gasoline contained in the carburetor float chamber. "Nine" itself should stall.
- Move the rocker switch to the "gas" position, and then check the operation of the car. If necessary, adjustment is made by means of a dispenser.
By optimizing the operation of the engine and installing modern gas installations, it is possible to achieve a car power that would be equivalent to that of a car using more familiar fuel. In addition, HBO is an economical and environmentally friendly equipment.
Natural gas is known to be cheaper than gasoline. Therefore, the installation of HBO will significantly reduce your costs. Most of the cars that travel on the roads of the CIS belong to the VAZ brand. Therefore, for those who have such a brand of car, this information will be useful and interesting. In this article, we will look at how you can connect HBO to your carburetor and which type is better to choose.
Which HBO is better to choose
For a car carburetor, any HBO of the 1st or 2nd generation is suitable. Yes, at the moment there are already 3rd and 4th generations, but for this type of engine it will be useless. Since they differ from older models in the presence of electronics, and there are no corresponding sensors on the carburetor engine, and therefore it is not worth installing the latest models. They will automatically turn into 1-2 generations.
There are practically no differences between the HBO of the first generation and the second. The gas hose is connected to the carburetor through mixer spacer or through a tie-in in the carburetor. Under the action of vacuum in the intake manifold, gas from the gearbox through the dispenser enters the carburetor. The only difference is in the gas dispenser.
In the first generation, the gas dispenser is manual, it is set to the desired position once and practically does not require adjustment. And the second generation has an electronic dispenser, with a valve that interacts with the engine depending on the readings of the oxygen sensor and the position of the throttle valve of the carburetor.
Such a second-generation system is not quite suitable for classic cars. But you can easily make 1st generation HBO out of it. To do this, it is enough to replace the electronic dispenser with a mechanical one. For a carburetor, it will be the best option for the first generation HBO.

Do-it-yourself HBO installation: instructions
When installing HBO with our own hands, we will use the following sequence:
- Mixer and valves installation;
- Installation of the reducer and dispenser, control panel.
Read only on the website Do-it-yourself car polishing
When we have determined the plan and sequence of work, we can proceed to the installation itself. So let's get started.
Cylinders are produced in two types: cylindrical and toroidal (popularly known as tablets). For cars with a classic layout, a cylindrical cylinder is best, since such cars have a large capacity. The best option would be to install the tank in the trunk, where there is a lot of free space. 
For hatchback vehicles, the trunk is located in the passenger compartment. Therefore, installing a cylindrical cylinder will not be the best option, it will take up a lot of space. Basically, such cars have a niche for a spare wheel. It is there that the balloon should be placed, but not cylindrical, but toroidal (tablet).
The balloon must be securely fastened. Otherwise, when moving, it will ride, and may damage the parts that are located on it. This can be done using a special stand and bolted metal strips.
After the cylinder is installed, it is necessary to remove the filling valve. Basically, the valve is mounted just below the rear bumper, securing it to the mounting plate. You can also remove the valve on one of the rear fenders. But for this you will have to drill a hole with the desired diameter in the place you need.
After we installed the cylinder, we are engaged in the wiring of the gas pipeline. To do this, we drill a hole from the multi-valve of the cylinder to the engine compartment. The gas pipeline should not pass in the cabin, it is better to run it along the bottom of the car.
It is better to drill a hole of a slightly larger diameter, insert a small piece of plastic pipe into it and fix it. This will provide additional ventilation for the multivalve.
We process anti-corrosion mastic inserted tubes. Then you need to conduct the pipeline itself. It should be well fixed and located as far as possible from the moving parts of the car.

Installation of a mixer and HBO valves
Now it's time to look under the hood of the car and determine the place for the rest of the HBO parts.
Mixer installation
Let's start with the mixer. In carbureted engines, the mixer is a spacer between the carburetor and the intake manifold.
Gaskets must be present between the three elements: manifold, mixer and carburetor, or sealant can be used. The main thing is that during the operation of these elements, there is no air leakage between them.
Install the fuel valve. It must be installed on the side where the fuel line is connected to the fuel pump. The valve must be installed in the pipeline. We cut the pipeline and install the valve in the cut, then “hard-wired” clamp it with clamps.
It should be noted that the valve is not located in front of the fuel pump, but in the fuel line going from the fuel pump to the carburetor. Otherwise, when shutting off and supplying gasoline, the gasoline pump will not be able to supply gasoline to the carburetor.
And the last one will be the gas valve. If possible, it is better to install it away from the gasoline valve. A large distance between them will provide you with complete safety in the event of an accident. It must be fixed in an accessible place so that, if possible, it would be easy to get to it.
A gas pipeline is carried out to the gas valve, which was previously laid from the cylinder to the engine compartment.
Mounting the reducer, dispenser and control panel
The next step is to install the gas reducer. It is best to install it near the carburetor. The gas reducer should be installed vertically, since in a different position its diaphragm will not be able to fully provide gas supply. The best option would be to connect the reducer to the pipes that go to the stove.
To do this, you will need to crash into the inlet and outlet pipes of the stove using two tees. Moreover, the serial connection of the reducer to one of the pipes can disrupt the operation of the system under certain conditions, so the inlet pipe of the reducer cuts into the inlet pipe of the stove, and the outlet pipe into the outlet pipe.
Our company performs the selection and installation of gas-balloon equipment for all types of both domestic and foreign cars. In principle, everything is limited only by the design features of a particular model, but our craftsmen do everything competently and accurately. The emphasis is on safety, so we use only certified and proven equipment.
Tell me, if I want to install a gas system on a car in your organization, do I need to buy the necessary equipment myself?
At Avtogaz, all work is carried out on a turnkey basis, and therefore the customer does not need to buy anything - all equipment is purchased by our specialists centrally, from trusted suppliers. Moreover, we not only install the equipment, but also configure it, so the car owner receives a completely ready and equipped car. We also give a long-term quality guarantee for all work performed, and therefore there is no doubt about the safety and durability of the equipment.
I have a small car, I want to switch to gas, but there is very little space in the trunk. If I install HBO, then nothing will fit in my car. Is there a possibility to solve such a problem?
We have already encountered such situations more than once and we can assure you that we will definitely find a way out. Here we are mainly talking about the location of the cylinder, which is quite voluminous. However, for such cases, we offer a special toroidal tank that can be installed in the spare wheel well. There are absolutely no difficulties here, since such a balloon does not use the cabin and trunk space. It is completely invisible to the eye, so feel free to come to us and we will install HBO neatly and quickly.
How much does the design of the car change when installing HBO? Is there any damage to the engine?
Starting with the 2nd generation HBO, the structural changes that are made to the car are minimal, and the safety of the car remains very high. Here, an electromagnetic type valve is installed in the break in the fuel line, which turns off the supply of gasoline. All equipment that we install is optional, so it can be removed and reinstalled on another car at any time. As for the effect on the internal combustion engine, nothing bad is observed here, since modern HBO systems have a sparing effect on the engine.
Why should I put on gas?
Reduced fuel costs
First of all, to reduce fuel costs. With the current price per liter of gasoline (30 rubles -35 rubles), gas equipment pays off in the shortest possible time. The more “gluttonous” the car, the higher the payback rate. The calculation of the payback of HBO specifically for your car can be found in the table below or calculated on our calculator.
Reliability on the road
The gas system is a redundant fuel system, which makes the car more reliable. If one of the fuel systems fails, you can always use the working one and get to the place of repair. It is also useful that on two tanks the driving range without refueling is increased.
Environmental friendliness
Save nature. Gas fuel is much more environmentally friendly than gasoline. Exhaust emissions are reduced in the following order:
- carbon monoxide (CO) - 2-3 times;
- nitric oxide - 1.2 times;
- hydrocarbon (CH) - 1.3-1.9 times.
After installing HBO, can I switch and drive on gasoline?
Yes, we install a special device that allows you to shut off the gas supply at any time and, if necessary, switch to gasoline operation. Thus, the customer receives unique advantages, which consist in the possibility of using both gasoline and gas.
I heard that after installing HBO on some cars, valves can burn through? Is it true or not?
If the gas-air mixture continues to burn at the moment the exhaust valves are opened, the valve very often overheats, which leads to its premature wear. To prevent this from happening, it is important to timely adjust the valves and correctly adjust the gas supply (system setting). Gas as a fuel has nothing to do with this process, since the valves burn out even if the car runs on gasoline.
The difference between the two gases should immediately be noted: methane is natural gas that is compressed in a car to a level of 200-220 atmospheres, and propane is a liquefied gas that is transported under a pressure of 10-15 atmospheres. Due to such a strong difference in pressure, different cylinders are required here, however, for safety, it is best to install LPG with propane operation. Such cylinders have a smaller wall thickness, and therefore are lighter in weight. It should also be noted that methane is measured in cubic meters, and propane is measured in liters.
