How to prevent the increase in fuel consumption
Why leaking gasoline?
Every driver would like to see his machine consumes as little fuel as possible. Against all "magical" fairy tales, to reduce consumption below the technical minimum can not be. But the increase under the influence of certain factors may well flow. It is these factors now will be discussed.
1. Fault in the electronic engine management system,
The primary reason.
One of the first reasons why can increase fuel consumption in a modern car. Consumption increases due to malfunction of the temperature sensors, throttle position sensors, flow sensors, the incoming air. In order to detect such problems should undergo electronic vehicle diagnostics. This method is optimal.
2. unnormalized pressure in the fuel system of the engine
The pressure is very important.
The situation with the high fuel pressure is dangerous, but it is rare. Where the pressure is more often low. In this case, the machine loses power. The engine works longer at higher revs, it loses its efficiency and, as a result, consumes more fuel. The reason for this is likely to be deterioration of the fuel pump.
3. Fault engine injectors
The injectors are cool.
Contaminated injectors cause the engine to run at higher speeds, resulting in increased fuel consumption. Also increases the load on the parts of the ignition system, which leads to faster wear them.
4. Breakage of catalyst
This is how bad.
Destroyed or Burned Catholic reactor is one of the nastiest reasons for the sharp decline in engine power and the same sharp rise in car fuel consumption. It occurs as a result of all this "blockage" of the catalyst. To avoid this problem, it should be timely to change the candles, often serve to fill the engine injectors and high-quality fuel.
5. A clogged air filter
Replace the filter on time.
The reason is known by any driver with experience, but somehow still remember in time to replace the ill-fated filter.
6. Faulty Machine
Check the box at the time.
Faulty automatic transmission significantly increases fuel consumption. This occurs by reducing the engine speed. To avoid this, we should not forget to diagnose gearbox and perform its timely repair.
7. The manner of driving
The basic principle of economical driving is reduced to the use of rolling and rapid transition to a higher gear.
It is not so simple.
Here things are not so simple. When driving in the city, the engine is often running at idle, and therefore, air conditioning has to select a part of the engine power to the compressor. This leads to increased fuel consumption. When driving on the road is much weaker air conditioning increases fuel consumption. That's because the engine is not running in idle, and therefore lack the power.
Pick the right oil.
An incorrect setting the oil viscosity for the engine, transmission, drive axles and transfer boxes greatly increases fuel consumption. Using oils with unreasonably high viscosity improves fuel consumption by 10-15%.
10. Operating temperature
Do not overheat the machine.
Motor overheating leads to imbalance of air-fuel mixture and the cylinder filling. Work "heart" on the impoverished mixture results in a loss of power and, as a consequence, increases fuel consumption.
And also: Wheels
A car with big wheels eat much.
Just do not use the car wheels, which are not provided for this model designers.
