Many drivers of vehicles opened a few years will be more and more waste oil, to maintain didn't check the problem, but everyone ignores several seemingly and fuel consumption to parts, they are actually gas-guzzlers.
1, tire
Fuel consumption mainly in overcoming all kinds of resistance loss, as long as it reduces the tire rolling resistance, the whole car resistance will fall, so they can achieve the goal of lower fuel consumption.Tire if wide, contact with the ground also relatively wide, friction resistance will be larger, fuel consumption nature is larger, if tire pressure is not enough, also can make the pick of the tire surface, increase the friction, may also make the both sides of the tire shoulder wear.In addition, if the tyre wear serious, will often appear skid phenomenon, fuel consumption will also increase.The normal life of general tyre is two years or 60000 kilometers, suggest the first to reach the requirements shall prevail.
2, oxygen sensor,
After oxygen sensor use for a long time to failure, fuel oil, lubricating oil, road conditions and China also has a lot to do, there are two main forms: sensor element aging and poisoning.Oxygen sensor aging is the main reason of the local surface temperature sensing element.Pollution of oxygen sensor sensing element and failure phenomenon called poisoning.Oxygen sensor poisoning mainly refers to the silicon, sulfur poisoning of carbon monoxide poisoning, lead poisoning, poisoning, manganese, lead poisoning and phosphorus poisoning.Once the failure, electronic fuel injection system of the computer can't get information on oxygen concentration in the exhaust pipe, concentration of mixture in the engine tend to be on the high side, fuel consumption will also increase.
3, carbon deposit
Engine in the process of work, the fuel in the unsaturated olefin and colloid in the condition of high temperature to produce a coke with material, carbon deposition.If you encounter in the driving speed is slow, come on tempering, cold start difficult phenomenon, the valve is likely to have your car carbon deposition.Found that idle speed low and when the idle car shaking, step on the accelerator card, change the battery without idle, so you have car the inlet pipe of carbon deposition is very serious.
4, the spark plug
The function of the spark plug is to tens of thousands of volts of high voltage into the combustion chamber, and generate an electric spark ignites mixture, and the ignition system and fuel supply system cooperate to make the engine work, it in engine operation plays a very important role, and vehicle fuel economy or not, whether running smoothly, has much to do.
5, battery
Most people don't lenovo battery and fuel consumption, the relationship between circuit and closely related to oil actually beyond imagination.When battery use time reach 2-3 years, will generate electricity phenomenon, resulting in starting voltage, the motor drives the engine is powerless, spark plugs can't jump out of the powerful spark, to make the ignition energy is low, fuel consumption will be soaring.
In the case of electricity shortage at the same time, the oxygen sensor and nozzle also can not work normally, partial rich mixture, fuel consumption will go up.So the service life of the storage battery as a only 2 to 3 years of consumables, the time is not hesitate, to move in!
