Installation of gas equipment on Lada Granta 8 and 16 valve

A car is an ideal form of transport for moving around the city and across different countries. But over time, gasoline does not become cheaper, and if you often go somewhere by car, trips will cost a lot of money. In order to save money, drivers are increasingly switching to gas. And although the Lada Granta is considered a fairly economical car, LPG, even with the cost of installing it, will save much more money in your wallet.

Generation choice

The first thing you should decide on before buying an LPG is which generation is suitable for this car? HBO for a second-generation Granta with a firecracker, which will also require additional heating of the gearbox - not serious for a modern car. And it is no longer economical, its technological characteristics are outdated.

The most advanced is the fifth. There are a lot of advantages: the power of a vehicle on gas is higher than on gasoline, gas consumption in quantitative terms is equal to gasoline. Huge savings, considering that gas is almost half the price. However, the cost of the fifth generation is still prohibitive for most car owners. You cannot yet find service stations with qualified and certified technicians for the installation and maintenance of this high-tech equipment even in big cities.

The optimal option for gas equipment for the Lada Granta is the 4th generation. This generation does not have the disadvantages of previous developments. The “pops” have disappeared, the drop in power is small, and when installing an ignition timing variator, this probability is reduced to zero. Economical gas consumption in comparison with previous generations due to the rational organization of injection of a propane-butane mixture into the nozzles.

How to reduce gas consumption

Motorists whose fuel consumption has suddenly increased sharply are wondering how to reduce gas consumption in their car. It is necessary to diagnose the machine under appropriate conditions and eliminate faults. However, there are some things you can do yourself.

Check the condition of the air filter and spark plugs - if they are in poor condition, they can significantly increase fuel consumption. If you know how, check the ignition timing - shifting it by 5 degrees increases gas consumption by 0.5 liters. Experts will help you deal with more complex cases.

Selecting the type of gas engine fuel

Methane fuel is cheaper than propane-butane mixture. In terms of price it wins significantly. Highly environmentally friendly fuel of natural origin. But there are as many pluses as there are minuses. The equipment itself and its installation are almost twice as expensive as CIS countries. This is justified because methane is not in a liquefied state like propane, but in a gaseous state.

Accordingly, the equipment must withstand this condition. This leads to the next disadvantage - the cylinders are heavy and bulky even for the spacious trunk of the Granta liftback. But they hold much more fuel.

Examples of savings calculations in St. Petersburg

Let's calculate the difference in the cost of refueling gas and gasoline using two examples:

From Nevsky Prospekt to the Ring Road and back in St. Petersburg 60 km. Let's take this distance as the daily mileage rate and calculate the benefit for the month.
From St. Petersburg to Moscow - 710 km. Let's calculate how much you can save on a trip to Moscow and back.

Savings after switching to gas

Engine	From Nevsky to Ring Road and back every day for one month			From St. Petersburg to Moscow and back
Engine	Petrol	Propane	Saving	Petrol	Propane	Saving
1.6MT	RUB 6,062	RUB 3,316	RUB 2,746	RUB 4,782	RUB 2,616	RUB 2,166
1.6 AMT	RUB 6,062	RUB 3,316	RUB 2,746	RUB 4,782	RUB 2,616	RUB 2,166
1.6 AT	RUB 6,668	RUB 3,651	RUB 3,017	RUB 5,261	RUB 2,880	RUB 2,380
Prices in calculations: AI-95 - 37.42 rubles, CIS - 18.61 rubles.

If you use LADA Granta rarely and travel short distances, the benefit will be insignificant. But if you spend more than an hour driving every day, HBO will pay for itself in the first year. Calculate how much you will save at the gas station based on your mileage in the savings calculator.

Selecting a HBO manufacturer

There are many manufacturers of gas equipment; choosing high-quality equipment is not difficult. Each brand has its own advantages.

Installing and configuring Digitronic gas equipment is not difficult; there are service centers for the brand in almost every city.

The original rack made of metal-ceramic HBO BRC has a resource of up to 250 thousand km (most brands have no more than 100 thousand).

A universal set of cables and a plastic case for inexpensive SEC ECO equipment. This LPG is equipped with the ATS function and is suitable for any injectors available on the domestic market.

The kit from Lovato fits perfectly even on the 127th engine.

Domestic brand - inexpensive gas equipment Alfa. The reducer is designed in relation to the quality of gas at our gas stations.

Polish Stag equipment, which is equipped with high-quality parts made in Italy using Polish technology, is in demand among motorists.

How to register an LPG with the traffic police? Instructions and rules

The procedure for making changes to the design of the car, including when installing gas equipment, is as follows:

before starting work:

undergo a preliminary technical examination. The examination is carried out only by accredited organizations, a list of which is presented on the website Eurasiancommission.org,
obtain permission from the traffic police to make changes;

after completing the work:

pass a technical inspection, undergo a re-examination, receive a certificate and enter its number in the PTS.

As I already said, it is easier to legitimize HBO than any other changes to the design of a car, since the certificate included with the equipment obviously makes the initial examination (clause 1.1) and the examination after the work (clause 2.2) meaningless. And reputable gas equipment installation companies obviously have the necessary forms from accredited expert organizations, of course, in full compliance with the law. Although you will still have to pay for both examinations.

We discussed in more detail the procedure for making changes in cases other than registering a gas equipment that has not yet been installed in a separate article.

Before installation

If the organization does not have the forms, then contact an accredited expert organization directly. If there is none in your city, then the request for an examination is sent by letter by mail.

Having received the conclusion of the first examination, we go to the traffic police and obtain permission to install gas equipment. There is no state fee for issuing a permit.

Installation of HBO

In fact, work can only be carried out in certified centers whose employees are certified to carry out work with gas equipment. The manufacturer of work to make changes to the design of the vehicle, according to GOST 31972-2013, upon completion of the work must transfer the following documents to the owner of the car:

application-declaration on the volume and quality of work to make changes to the design of the vehicle, drawn up by a legal entity or individual entrepreneur,
a duly certified copy (by the LPG manufacturer, supplier or seller) of the certificate of conformity for the LPG kit that you are drawing up regarding its installation on a specific type of vehicle with annexes on the composition of the kit, indicating the designation of the documentation for the components and their compliance with safety requirements ,
a certificate of form 2a certified in the prescribed manner on the compliance of the vehicle with the safety requirements established for it by the HBO,
a certificate of form 2b certified in the prescribed manner on the conduct of periodic tests of the gas equipment installed on the vehicle.

After installation

1. The next step is visiting a technical inspection point

Please note that the diagnostic card you receive based on the results of the technical inspection contains a note about the installed gas equipment. In particular, the curb weight of the vehicle will increase in accordance with the weight of the set of gas equipment with a filled cylinder and a mark indicating the new type of fuel must be indicated

2. After passing the technical inspection, we undergo a second examination. As I already said, you do all this in the same organization that supplied the equipment.

3. Next - to the MREO for registration of changes to the design.

You will have to visit the traffic police in two stages, especially if you register through State Services. At the first stage, you receive a “Certificate of Changes to the Design.”

On the second - a new registration certificate, with entries made in the PTS.

state duty for a certificate for making changes to the design - 800 rubles,
for a new registration certificate – 500 rubles,
for making changes to the PTS – 350 rubles.

It’s cheaper through State Services. And don't forget to make copies of all documents!

What inconveniences will you have to put up with?

HBO has few disadvantages, but they must be taken into account:

You will have to spend money on high-quality gas equipment and installation in a specialized service. Installing high-tech equipment in a garage or with your own hands is difficult and dangerous. In addition, troubles such as dips when pressing the accelerator pedal while using gas may appear. If the gearbox is connected to a heating/cooling system in a home-made manner, it may freeze.
It is necessary to carefully monitor the regularity of scheduled technical inspections and checks of the gas tank.
The gas cylinder will take up some space in the trunk. The way out of this situation is to place a toroidal cylinder in the lower part of the trunk instead of a spare wheel.
If the Granta is under warranty from the dealer, then it will lose it.

On a note! A slight decrease in vehicle power can be successfully solved by installing an ignition timing variator (IAC), which increases the efficiency and performance characteristics of the engine.

Installation and Maintenance

If you think that you can install a gas cylinder yourself without experience and skills in this matter, then you are unlikely to succeed. To install the equipment, it is better to contact specialists. When working, you need to weld brackets and carry out wiring, which a non-professional cannot do efficiently, and safety depends on the quality of the installation. The 42-liter tank is installed in the spare wheel well. Then it can be covered with trim, and the trunk will look aesthetically pleasing again.

If the niche is too small for you or you need it for other purposes, then a cylinder (cylinder) with a volume of up to 80 liters can be installed directly in the trunk.

In the Lada's interior there is a button that switches the fuel type: from gas to gasoline and vice versa.

IMPORTANT! If the gas runs out, the car automatically switches to gasoline fuel.

You can also install a Euro multi-valve. With its help, the driver will be able, while in the cabin, to see how much gas fuel remains in the cylinder.

In order for the equipment to work for a long time and without interruptions, it must be serviced in a timely manner. This includes regular replacement of filters, purging of the editor and fuel line, and setting up the software.

Possible problems on different control units

For example, the first problem, which is also the simplest, sounds like this: “What to do with the fuel pump and injectors?” The answer is also simple - it is recommended to turn off the injectors. Here are some ways to do this: the first is the software method. Specialists use firmware for two modes - gas-gasoline, and when the LPG works in the Lada Granta, the injectors do not work. The second way is to turn off the injectors using a relay or an injector emulator. You can do the same with the gasoline pump to prevent it from running idle. Or you can leave the pump on and thanks to this the injector ramp will quickly cool down.

There are “January” firmwares (not yet installed on Granta, but in the future it is possible) - they can implement firmware with a dual-mode program. There are two parts of the program for working with gas equipment - as the name implies, gasoline and gas. Injector and fuel pump drivers with ignition correction for optimal functioning with gas are disabled. In the BOSCH M 1.5.4 control unit. There are also two modes, but if you use it for the Lada Granta, you won’t be able to turn off the injectors, because there is only one program, but there are two calibration sets. In this case, use direct shutdown and a simple injector emulator. Complex types of emulators contain field keys that are needed to obtain a disconnection without interruptions. There are options when the process of switching between firmware is done automatically. The gas valve turns on and, accordingly, the firmware for gas should turn on next. Moreover, with such a switch on the Lada Granta, a short circuit to the ground terminal from pin 52 of the ECU may occur.

In addition to what has been described, there is another problem - how to implement the correct gas supply. This is especially true for transitional modes, in which the combination of systems with gas-cylinder equipment is not initially envisaged. For example, we can mention a long coasting motion, and then when the throttle opens you can hear “pops” - this is how the lean mixture in the receiver explodes. When the car is coasting, a very rarefied atmosphere is created in the receiver, and when the damper is already open, a large amount of air is sucked in. HBO does not take such things into account, and explosions result. Because of them, it may happen that the mass air flow sensor fails. Three to five strong “claps” are enough. That’s why receivers have firecrackers at the input—this is done when installing HBO. True, the pops still remain, but there are fewer of them. The dynamics of the car may change for the worse. In the Lada Granta with gasoline, the passage hole at the receiver inlet becomes narrowed. The firecracker itself can also become deformed during explosions.

There are cases when popping noises also appear when using gasoline fuel - when the ignition is turned on. During the process, gas enters the receiver without interruption - that’s why popping noises can be heard constantly. When the ignition is turned on, there is a spark - this is how some injection systems turn out to be a glitch. To get rid of it, it is recommended to install a relay that will delay the supply of power to the ignition module. Some people also call it “anti-fluff”.

Now let's talk more about the third problem. It is connected to new electronic control units from Bosch - MP7.0 and M7.9.7. Such systems were developed for toxic standards according to Euro-2 and Euro-3 standards. The fuel supply calculation contains a mathematical model of the engine. The mathematical model will change all the time - it depends on the conditions of use and modes - this is called self-learning of the system. This is why it is impossible to switch to gas from gasoline at any time - in order for the Lada Granta to run on a different fuel, you need to programmatically reset the ECU - so to speak, clear what the system itself has learned. If the memory is not cleared, the machine will not work normally in either mode. That is why it is so difficult to install gas cylinder equipment on injection machines if they have BOSCH, MP 7.0. This block must be changed to “January” in any modification of the fifth version.
