If the steady fuel consumption suddenly increases, many people will suspect that it is because the car is aging, or because of their driving habits, they will not consider the car accessories at all. In fact, many car accessories will become the culprit of fuel consumption if they fail. The culprit, the fuel consumption suddenly increased, it is very likely that these five parts have failed!
Tire
If the tire tire pressure is unstable, insufficient air pressure will cause the tread and road surface contact area to be too large. Increased friction will lead to increased fuel consumption. At the same time, it will accelerate tire wear and reduce tire life. If the air pressure is too high, there is a risk of puncture. Driving In the middle should develop the habit of checking tires, once the fuel consumption rises, first consider whether the tire is a problem.
Intake system
When the exhaust back pressure is reduced, the low torque will drop, the engine exhaust valve will be easily burned due to the ultra-high temperature, the torque consumption will be suddenly increased, and the symptoms such as acceleration and weakness will be accompanied by cleaning the air filter. Maintenance of the intake system can also reduce fuel consumption.
Spark plug
The quality of the engine can be judged by whether the gasoline is fully burned. This has a great relationship with the breakdown voltage of the spark plug. The spark plug is poorly ignited, which is easy to cause the starting of the car. The fuel burning is insufficient to cause the fuel consumption to increase. If the above problems occur, it should be timely. Replace the spark plug.
lubricating oil
Many people wonder what the lubricating oil has to do with fuel consumption. Too much lubricating oil will cause the oil to participate in combustion. Insufficient combustion of combustible gas will result in increased fuel consumption due to gasoline waste. Less lubricating oil will increase engine friction and power will reduce fuel consumption. The lubricating oil must be kept at a normal level. Too much or too little will cause an increase in fuel consumption.
engine
If the engine carbon deposit is serious, it will lead to an increase in fuel consumption. Carbon deposition is not formed overnight. It requires a long process. Once the carbon accumulation is serious, it will be difficult to clean up. At that time, not only the fuel consumption will increase, but also the engine failure will be seriously caused. , and may even be scrapped.
When your car's fuel consumption suddenly rises, after driving reasons and age, it is necessary to consider whether these five accessories have failed.
