Can we talk about some kind of fuel economy in production cars? This is perfectly acceptable. Moreover, the more expensive the car, the less technology to put the car on a "diet". Let's look at the main points that will help you achieve this goal. Also in today's article, we will consider life hacks from the owners on how to reduce the fuel consumption of domestic carburetor and injection engines.
Petrol
For the sake of economy, many are trying to refuel their cars with more affordable A92 gasoline. At the same time, the price only seems low - the consumption of such gasoline on modern injection cars is slightly higher. A carburetor basically doesn’t care, but experienced drivers say who uses a better gasoline carburetor engine to drive better, which means less will be needed to cover some distance.
Also, on the question of how to reduce fuel consumption, special grades of gasoline, which have an increased cleaning ability, will help. Sellers say with confidence that the percentage of savings can be up to 10 or more. This is actually so - this fuel really reduces the "appetite" of the engine.
However, blindly trust advertising is not worth it. It must be borne in mind that it is not always true. The test results were obtained, but they were carried out almost in laboratory conditions, while the video is a complete statement. If you pour A98 gasoline into a new engine and compare it with a well-used car that consumes the 95th without detergent characteristics, then the result will be exactly these ten percent. But as the dirt from the engine is washed away, the difference will begin to disappear.
Therefore, it is better to use higher octane fuel for economy - it is more expensive, but it needs less. And this is a saving. But this will be the case if, instead of the 92nd, fill in the 98th. There is practically no difference between the 92nd and 95th.
Oil
You can slightly reduce the "appetite" of the machine with other oils. This is true for mineral types. A big plus will not work, but if you pour energy-saving oil with a class higher than SL into the engine, the result in reducing consumption may not be so bad - just replacing the oil can get fuel consumption five to six percent lower. On individual engine operating modes, you can save even more. For example, at minimally stable idle speeds, up to ten percent of gasoline is saved. But recently, domestic consumers have been accustomed to lubricating fluids 0W20. The savings, as they say, are huge - oil is almost like water. In winter, this is a plus, but in summer it can go sideways.
Wires and candles
When a car owner buys good, expensive, quality candles, he saves fuel. Candles can save about a few percent of total fuel consumption. The energy of the spark discharge creates an impulse to the flame front. The speed of flame propagation affects not only power, ecology, but also profitability. Well-selected candles can improve the efficiency of the power unit by 2-3 percent.
Iridium as well as platinum candles are able to work three or even four times more than usual. The materials of the electrodes are refractory, which makes it possible to reduce the size of the electrodes, increasing the field strength in the space between the electrodes. This improves the stability of the spark discharge and its stability. Due to a more powerful discharge, the cleaning of the electrodes and the insulator improves - the candle works better.
Fuel consumption also depends on the clearance of the plug. This is one of the ways to reduce fuel consumption on a carburetor - says Nail Poroshin. Although specifically the carburetor, this does not apply. The larger the gap, the greater the spark will become, as well as the initial source of ignition. The speed with which the flame spreads is very dependent on the size of the ignition zone. However, if you start to increase the gap, the resistance will also increase. Therefore, the breakdown will be in the secondary circuit. And it is very important that there is enough voltage for the breakdown. For injection engines, where the secondary circuit voltage is higher than on carburetors, large clearance on the candles can save. On the carburetor, the clearance is set on a special probe.
Next is about wires. Owners of old cars, who often and often think about how to reduce fuel consumption, never pay attention to the wires. Usually carburetors begin to sort out right away. But in vain. Good wires can help save fuel. For wires, the main thing is quality, as well as the tightness of the tip, the tightness of the caps, the distribution resistance and, of course, the length.
The length is especially interesting. Most wires have different lengths for ease of installation. But for the formation of a spark discharge, each time the voltage travels a different distance. This slightly disrupts the engine. If the wires had zero resistance, then there would be no difference. There is resistance both in the candle and in the wire, while no one has ever measured the sum of these resistances, but in vain.
Filters
It would seem that air and oil filters have almost no effect on fuel consumption. But actually it is not. Of course, significant savings cannot be achieved, but the task of how to reduce fuel consumption at the VAZ requires an integrated approach. The type of filter does not significantly affect the flow, but the state does. The condition of the air filter is especially important. The greater the airflow resistance, the worse the cylinders are filled, and this immediately significantly affects the level of fuel consumption. Depending on which company made the air filter, the resistance can change for the worse up to two times. Testing shows that installing a clean filter provides a few percent savings.
HBO
Many car owners, seeing gas prices and not having figured out how to reduce fuel consumption, are thinking about switching to gas. This is also a kind of savings, but not always and not for everyone. Although you can save about 30 percent compared to gasoline.
You can switch to gas right now, but there are also disadvantages. The car will lose throttle response and agility. There will be less space in the trunk due to the balloon. There will be difficulties with starting in the winter. But for those who set themselves the task of how to reduce fuel consumption at the UAZ, saving is important, and you can close your eyes to the cons.
Additives
Numerous car manufacturers also produce various "drugs" designed to reduce fuel consumption. It is better not to fill these mixtures in warranty cars. The effect in terms of reduced consumption will be small. In addition, various consequences are possible.
Tires
Some leading car manufacturers complete their cars that come off the assembly lines with special energy-saving tires. They differ in minimal rolling resistance. This provides savings of up to 5%. As for the resource of this rubber, it is almost equal to the service life of ordinary rubber. The main drawback is the price. It is higher in comparison with ordinary tires.
But how easy is it to save some fuel? Before driving, increase the pressure in the tires. And finally, you just need to monitor the pressure. Lower pressure is uneconomical, and high pressure makes the car too stiff.
Catalyst removal
Here's how to reduce fuel consumption on an injector. If the catalyst is in normal condition, then there will be no effect on flow after removal. Its resistance is very small to score the issue. If the neutralizer is completely clogged with various deposits, then it will serve as a cork on the exhaust tract - after removal, the engine will definitely feel this and respond with a more economical flow rate.
Thus, it is possible to reduce fuel consumption for the VAZ injector, as well as on more expensive models.
Driving style
It’s not always possible to reduce the “appetite” of a car with the help of technical tricks. But changing the driving style, you can save tens of percent. Many people prefer to accelerate sharply and also brake sharply. In order to move the car from its place and give acceleration, the bulk of the fuel goes. In the process of movement, it is consumed more evenly. If you drive smoothly, you can achieve a satisfactory flow rate.
Carburetor
On the Internet, motorists discuss the same topics. With the help of forums, owners of carburetor machines are trying to figure out how to reduce fuel consumption on a carburetor. There are a lot of different ways to refine the carburetor. But to get a good result, you need to do a lot of work, which will require a certain skill, knowledge of carburetor theory and the principles of the internal combustion engine, precision equipment for the manufacture of tuned carburetor parts.
The first thing they usually resort to is bending the nozzles of the accelerator pump into the first chamber. There are opponents of this idea and their fans. But in fact, the expense of this will not decrease, but, on the contrary, will be higher. In the process of movement on the first chamber, the second shutter is closed, and the spill of fuel into the second is minimal. In turn, when the trunks are bent into one chamber, the carburetor will suck out more fuel.
Another option that does not require any precise machine tool, or knowledge of theory. As you know, fuel enters the combustion chamber through special metering elements - jets. To reduce fuel consumption, nozzles are installed smaller than those that were. But first, you need to measure the flow rate - pour fuel into a bottle of one liter. Next, the fuel pump hose is lowered into the bottle. For the event, you will need to purchase jets of a smaller and larger cross-section - they purchase idle jets, as well as the main fuel jets.
Next, the motor is heated to operating temperature, the bottle is connected. It is necessary to pass the control section, while the speed should be kept at the level of 60-70 kilometers per hour. Next, measure the level remaining in the bottle. Then change the nozzles to smaller ones and again pass the same distance in the same section. It is important to monitor the dynamic characteristics of the machine. If there are no failures, then they put an even smaller jet. If a failure occurs, then install a larger idle nozzle.
If there are no failures, then everything is fine and you can leave this configuration. The quality of the mixture can be estimated by looking at the candles after the trip. If they are black, in tan, then you can try to change the nozzles. Here's how to reduce fuel consumption on a VAZ carburetor - replacing the jets can save a liter or more of gasoline.
UOZ
To check, you will need a stroboscope, as well as a key for 10. The motor is heated to its operating temperatures. Next, set the low speed and turn off the engine. On the gearbox housing, a hatch is found in which the flywheel is visible. There is a scale on the flywheel. Turning the handwheel, find a long mark. In this case, the lead angle of 0 degrees will be if the mark is opposite the triangular notch.
Next, connect the strobe. The beam of the device is directed into the hatch. The label should be on the desired division. If it moves, then rotate the distributor housing and set the mark to the desired position.
Here's how to reduce fuel consumption on the Niva and other carburetor models. This is true for carburetor foreign cars, which are still quite a lot.
Injector
There are many factors affecting consumption. This is an ECU, and a large number of sensors. For example, a faulty lambda sensor can increase fuel consumption by 10 liters or more. A faulty temperature sensor also affects flow.
Some solve the problem of how to reduce fuel consumption on a Chevrolet or other similar cars, using chip tuning. Consumption really drops. You can install fully known working sensors, monitor the air filter. Also, at high flow rates, it is recommended to look for air leaks in the system and eliminate it. Often, it turns out that the owners significantly reduce fuel consumption at the Lanos.
Conclusion
So, we looked at several ways to save fuel. If you put together all of the above, you will get very good savings. Before leaving, you should check the tire pressure, regularly change the filters, keep the throttle valve clean, and also change the spark plugs and wires if they work poorly. Do not forget about the ignition timing.
