Large gas consumption for cars with compensation. How to reduce gas consumption on a car

Large cash costs for fuel are a natural problem for every car enthusiast. The presence of a car has a strong impact on the family budget at current prices for different types of fuel.
It is known that LPG is installed on a car to save on gasoline and diesel fuel, the price of which is constantly growing.

Consumption of gas in relation to gasoline is more profitable. Nevertheless, having installed HBO, it is unlikely that it will be possible to forget about fuel costs, you still need to monitor gas consumption. There are many factors due to which the consumption of gas and petrol can increase. Often increased consumption gas or gasoline can cause a significant impact on funds. If you see that the gas consumption has increased, then this does not always depend on the malfunction of the gas equipment, the presence of this problem is also possible in other cases.

• Malfunction of the gas injection system, adjustment is necessary.
• Incorrect selection of calibration nipples gas injectors.
• Gas reducer malfunctions, adjustment and heating.
• Faults in the gas injectors.
• Low engine compression.
• Defective operation of the oxygen sensor (lambda probe).

General factors influencing the increase in the consumption of different types of fuel

First you need to pay attention to the quality of the engine. Various disturbances in the functioning of the driving force can lead to increased fuel consumption. Also, the reason may be optional equipment... Another common factor: the wrong way to drive a car. For example, fuel consumption will increase if there is a high speed while driving.
Some characteristic problems that lead to an increase in fuel consumption:

• malfunction of the on-board computer;
• dirty filters;
• pressure surges in the fuel system;
• malfunction of the automatic transmission;
• failure of the autoradiator system, respectively - lack of engine cooling;
• incorrect injector program.

Malfunction of the ECS and injection system

The processes occurring in the operation of the engine of many modern cars are controlled by special sensors. They are connected directly to the ECS (electrical control system), so fuel consumption is regulated and more. Electrical failure and sensor errors affect the fuel mixture. The composition of the mixture can become poor or oversaturated. In one case or another, the driving force of the car loses power, and, accordingly, fuel consumption increases. As a result, it is necessary to diagnose the operation of the temperature sensor for malfunctions.
The fuel supply system (injector) is one of the main devices on which the correct operation of the engine depends. It is necessary to keep the injector clean, remove the accumulation of soot and dirt regularly and sometimes diagnose for prevention. The use of dirty injection nozzles affects the atomization of the mixture, part of the mixture burns out in the manifold or catalyst, which leads to their damage. Poor performance of this device directly affects the drop in the level of acceleration of the car, there is a load on the gearbox, which also affects the increase in fuel costs.

Violated fuel pressure and automatic transmission malfunction

The loss of fuel is caused by increased pressure, at which the fuel mixture is enriched with additional fuel. But this happens very rarely. Too low pressure has a greater impact on fuel consumption. At the same time, engine productivity is noticeably reduced. internal combustion, the dynamics of acceleration of the car weakens, and the ESU does not have time to make up for the lack of fuel in a certain period of time.
The reasons for underestimated pressure include wear of the fuel pump mesh, fuel filter or himself fuel pump using low-quality gasoline.
The first sign of a malfunction of the automatic transmission is an uncharacteristic sound for the engine, which indicates an overload, followed by an increase in fuel consumption. In this case, stop further operation of the transmission, which leads to fuel consumption, and contact service center... By the way, on the machine, the consumption is usually 1.5 liters higher in relation to mechanical box gear.
The presence of an air conditioner. With an air conditioner, if the consumption of gasoline or other fuel increases only in the summer, then this is normal. Engine operating parameters partly affect the energy consumption of the air conditioner. When driving around the city, about 20% of fuel consumption is accounted for by the air conditioner, and when driving on the highway, the percentage of air conditioning costs is almost invisible.

Effect of engine overheating on fuel consumption

The stability of fuel consumption depends on the acceptable temperature in the engine system. At elevated temperatures, the ratio of the mixture of fuel to air is disturbed, since the fuel quickly evaporates in the intake manifold. The stability of the engine parameters is lost and the power is significantly reduced. ECU sensors receive an incorrect signal, and the pressure drops fuel system, this leads to excessive consumption of fuel.

Reasons for overheating of the engine device:

• Unacceptable position and operation of the thermostat.
• Faulty water centrifugal pump.
• Radiator obstruction, radiator not tightly closed.
• The need to flush the engine cooling system.
• Defective cooling fan.

The engine uses an immense amount of fuel mixture if the thermostat does not work correctly.

Air supply problems, oxygen analyzers

Clogged filters reduce engine efficiency and economy. Disruption of the filtration function weakens the air supply, which reduces the efficiency of the engine and causes excessive fuel consumption. The lack of the required amount of oxygen in the air interferes with the combustion of the mixture, hence the danger of a malfunction in all vehicle systems. Oxygen analyzers supply incorrect ESA readings, and due to incorrect calculations, gasoline is also over-consumed.

Saving behind the wheel - adequate driving

Often, excess gas or other fuel consumption is the fault of the driver. For example, constant acceleration and deceleration, overtaking. This is more common in city driving. In this mode, it is difficult to save on fuel, and for heavy cars, it is even more difficult. Urban traffic jams are also an integral element in the process of which it is unlikely that it will be possible to reduce consumption.
Some modern cars have a special device for monitoring the consumption of the mixture, which allows you to clearly see the fuel consumption when increasing the speed. Motorists, having analyzed the consumption of different driving habits, learn not to take a sharp acceleration. A certain distance before stopping can be driven in idle - the car is heavy, therefore, it will drive by inertia for a long time.

Fuel consumption measurement:

• With a device installed in every vehicle to track fuel consumption. This method is the simplest, but not effective, errors are observed.
• Fuel consumption measurement mechanical method using calculations. It is necessary to fill the tank according to the mark refueling gun, drive a certain mileage and refill the tank. Then the number of liters is divided by the mileage, after which the result must be divided by 100 km. This method is more productive.
• With a diagnostic tool, the measurement result is approximate.
• The on-board computer allows you to see the exact consumption, but not every car owner can afford it.

Effective methods to reduce fuel overconsumption

Today, software chip tuning is a simple and proven method to reduce fuel consumption. This is especially true for cars with a small engine displacement.
After carrying out a high-quality adjustment, the motor power should increase, and then a decrease in consumption can be achieved. different kind fuel. After tuning, the data is measured by a special device that is able to give accurate information, which allows you to make sure that the tuning is productive in terms of reducing overspending.

Some advice and observations of motorists on the question - why overrun?

• There is a concept - heavy and light gas. A noticeably low gas consumption is observed with the correct ratio of butane and propane in the mixture, butane should be more.
• Different types of gas are consumed in different ways.
• To reduce consumption, check the tire pressure, low - increased consumption. Change air filters more often.
• At elevated air temperatures, the gas expands, if possible, it is better to refuel early in the morning, when the containers are still cold.
• Manufacturers recommend re-sorting the gearbox every 60 thousand km with the replacement of all repair kits.
• To maintain the flow rate at an acceptable level, it is necessary to periodically adjust the CO every 4-6 months.

Acceptable fuel consumption of UAZ vehicles

UAZ (Ulyanovsk Automotive Factory) Is a car with four-wheel drive, increased cross-country ability, fuel consumption is moderate. The advantage of this machine is that front axle the machine is usually shut down and operational if necessary. According to observations, if the front axle of the car is in the on mode, the fuel consumption is increased. The built-in injector helps to reduce fuel consumption. The peculiarity of the engines of the new production of UAZ is the extreme efficiency, economical fuel consumption.
Examples of consumption of different types of fuel for some UAZ brands (manufacturer's information), liter per 100 km:
—Hunter (2012, engine - 2.7, gasoline):
Officially: in the city - 14 liters, on the highway - 10.5 liters; in fact: in the city - 16 liters, on the highway - 12 liters.

—Patriot (brand ZMZ - 514, 4-euro, diesel):
in summer: in the city - 12-14 liters on the highway - 9-11 liters;
in winter: in the city - 14-16 liters on the highway - 11-12 liters.
— Brand - 3163 patriot (motor - 2.7) and brand-3164 patriot (motor - 2.7): 12.5 l
— Brand - 3963 (2.6 - volume, gas): 19.3 L (according to owner's tests).
— Loaf (2014, motor - 2.7): on the highway - 8 liters in the city - 10 liters.
— Loaf (1991, 2.8): 20 l
— Brand - 23632 pickup (2,3 - volume): 11.5 l
— Brand - 469 (2010, motor - 2.7): on the highway - 11 liters, in the city - 15.6 liters, off-road - 17 liters.
It is noticeable that the consumption of different types of fuel does not exceed 20 liters per 100 km for almost all UAZ brands, which is acceptable.
Observing the maximum speed when driving in the city, the fuel consumption of UAZ vehicles can be reduced to 11 l / 100 km.

Diesel engine to reduce fuel consumption of the Gazelle

The use of diesel fuel at the Gazelle helped to reduce the overall consumption indicator by about 30%. As a result, the total cost has dropped. The owners install gas equipment in the car of this brand to further reduce the price of the car. Thus, fuel consumption has decreased to 14 liters per 100 km.
Examples of the consumption of different types of fuel of some Gazelle brands (manufacturer's information), per 100 km.

Good day to all kind people. The article will tell you, how to reduce gas consumption on an LPG car(gas equipment). The use of gas as a fuel source is gaining momentum and increasing every year. Perhaps the time is not far off when gas-powered cars will begin to displace petrol and diesel models from the market.

Already, a car with LPG has a number of advantages over traditional gasoline and diesel internal combustion engines. Better alternative vehicles powered by electricity. Despite the high efficiency gas fuel drivers are thinking about lowering fuel consumption and reducing the cost of refueling the car.

In principle, any HBO, with proper tuning and proper installation, is economical in fuel consumption, but you always want to reduce costs as much as possible. After reading the article to the end, you will know exactly how to properly reduce gas consumption on an LPG car.

When choosing gas equipment (LPG) for a car, you should give preference to installations of the latest generation that meet modern safety and reliability requirements.

The latest generation equipment is distinguished by an optimal price-quality ratio. With proper installation and subsequent regular maintenance, HBO will last for a long period of time.

Often, incorrect installation of LPG leads to an increase in gas consumption by a car. Increased gas consumption is an indicator of a malfunction of a separate piece of equipment.

Reducing gas consumption for LPG:

1. Setting the optimal pressure in the reducer. The setting is carried out via the electronic control unit.

2. Elimination of freezing of the gearbox. The optimum temperature level for heating is set.

4.Optimal diameter of the nozzles. The large diameter increases the gas flow rate.

5.Working lamba probe.

6. Timely replacement of the air filter.

7.Installation of the ignition timing variator. The variator controls maximum gas combustion to ensure high efficiency.

8. Installation of HBO of the latest generation. New equipment is 10-20% more economical than previous versions.

Imagine, at an increased LPG gas consumption there may be more than 20 reasons! And most of them you can not only independently determine, but also eliminate. Therefore, do not rush to immediately go to the service station, but read our recommendations below. Just in case, we remind you: for conventional systems HBO consumption 15-20% higher gasoline consumption, for Italian PRIDE by AEB 4th generation systems - 10%. If this value is higher, look for the reason.

Increased consumption of HBO: looking for the cause

1. Late ignition. Shift of the lead angle by 5 degrees. Increases gas consumption by 0.5 liters. The solution is to install an ignition variator.
2. Replacement of spark plugs or adjustment of the gaps between the electrodes is required. This reason affects more the consumption of gasoline than gas.
3. Headlights on. The generator needs more energy to generate current, it takes some of it from the fuel. Especially increased consumption of LPG when driving at low engine speeds.
4. Inconsistency of the temperature of the antifreeze with the standards. Change the antifreeze in a timely manner (every 2 years) and there will be no problems.
5. Warm up the engine for at least 1-2 minutes in the fall and 3-5 minutes on gasoline in the winter. And only then switch to gas - HBO consumption 4 decreases by 3-5%. For the 5th generation, the engine warm-up time is reduced to 1 minute in winter;
6. Increased wear CPG (compression drop is a problem of a car with a mileage of more than 300 thousand km). The overhaul solves the problem.
7. Wear of KShM.
8. Clutch wear. Large consumption of LPG gas 4 may be due to a loose disc in the clutch basket. If there are still problems in brake system, then the excess of the flow rate can be more than
9. Problems with adjusting valve clearance and gas distribution mechanism.
10. Overtightened hub bearings.
11. Camber is not exposed.
12. Reduced (increased) tire pressure over 0.2 atm. from the norm;
13. Weight overload of the machine: trailer, roof rack, "kenguryatnik" - due to aerodynamic properties LPG fuel consumption may increase by 1-2 liters.
14. Aggressive driving style: abrupt start with overbraking, overtaking on increased revs driving above the "cruiser".
15. Clogged filters (fuel, air). The problem is solved by replacing them.
16. Problems with injectors, carburetor (unadjusted, without cleaning from carbon deposits, the carburetor increases HBO consumption 2 generation 1-2 liters).
17. Filling the tank with poor quality fuel. For gasoline, a decrease in the octane number increases consumption by 10%, similarly with gas - filling fuel with additives and impurities can increase consumption by the same 10%.
18. Headwind. Yes, as fantastic as it sounds, wind and uphill driving are fuel-intensive. True, you can coast back and save gas.
19. Driving on a highway with a low grip coefficient. Example: winter track (ice), road after rain. Slippery wheels spin faster and consume more fuel.
20. Incorrectly adjusted LPG gearbox and injectors (incorrect selection of jets).
21. Errors in setting up LPG. Outgoing pressure on the gearbox, adjusting the nozzles on the ECU - all these are the reasons, albeit insignificant, but gas consumption.

Nowadays, more and more car owners decide to convert their car to gas. LPG equipment is a great way to save on fuel. But drivers, even after installing LPG, are looking for ways to reduce the consumption of the propane-butane mixture and, as a result, their funds. In order to maximally reduce gas consumption by 100 km, you need to understand the reasons for its increased consumption. We offer you 7 of the most frequent reasons increased fuel consumption.

Reason 1 - gas leak

Gas leakage is the most common cause of high consumption LPG gas. The propane-butane mixture can flow through main gas lines, gas nozzles or fittings and joints of pipes and a cylinder, for example. Please note that even if there is no smell of gas, this does not mean that it is not leaking.

Reason 2 - gearbox wear

The reducer is the main element of all LPG equipment. The reducer reduces the gas pressure to optimum operating condition. If it wears out or breaks down for any reason, then the amount of fuel needed to run the car increases significantly. This means that the gas consumption per 100 km of track is also growing.

Reason 3 - carbon deposits on gas nozzles

Breakdown, wear or corny contamination of gas injectors provokes a large gas consumption. The reasons for this are as follows: the injectors open and feed the gas-air mixture into the cylinders. If the injectors are carbonized or defective, the fuel delivery time will increase. As a result, a large consumption of LPG gas.

Reason 4 - interruptions in the electronic control system (ECU)

The ECU is responsible for the ignition. If the system is faulty, the propane-butane mixture needs more. Only then will the ECU react and provide the ignition. Increased fuel consumption leads to increased gas consumption per 100 km.

Reason 5 - broken candles

Candles like electronic system controls are responsible for the ignition. The charge that is created between the spark plug electrodes ignites the gas-air mixture and drives the engine. If the candles are soaked or completely defective, then the gas consumption increases.

Reason 6 - driving on a cold engine

If the engine is not heated to the required temperature with gasoline, then a small amount of propane-butane mixture is spent on this. Daily trips on a cold engine will result in gas overruns of up to 20%.

Reason 7 - poor quality propane-butane mixture

Very often, gas stations sell unenriched gas. In order for the car to work as usual, more such fuel is needed. Moreover, an unrefined mixture can adversely affect the condition of the equipment and parts of the machine.

High gas consumption, the reasons for which we described above, is a major problem for all car owners. Malfunctions of parts or poor quality of fuel not only increase the overspending of the propane-butane mixture, but also shorten the life of the vehicle equipment. If you notice that you are refueling more and more often, then you should immediately contact the service station or doubt the conscientiousness of the gas station.
