Fuel consumption is getting higher and higher, replace these components, fuel consumption will soon drop, the car will be quiet. The longer the service life of any brand of vehicle, the more it will naturally produce some shortcomings. The result belongs to the product of the machine, if the parts inside become longer, it will naturally produce a certain loss. Especially when cold start, the wear is the greatest, but with the increase of time and kilometers, it will age, can not be used and can not be replaced, and the fuel consumption is high.
Spark plugs, spark plugs themselves have a lifespan, and their lifespan is usually 60,000 kilometers. As the vehicle progresses, the effect of the spark plug decreases, but the difference is smaller, and the ignition becomes worse by the end of the spark plug's life. Since both situations can lead to an increase in fuel consumption, the vehicle traveled about 60,000 kilometers, but if the fuel consumption is found to rise significantly, it is likely that the spark plug will need to be replaced.
Oxygen sensor, the role of the oxygen sensor is to detect the air-fuel ratio and feedback to the engine computer, the engine computer fine-tuning the amount of injection, so when the oxygen sensor is normal, if the feedback to the computer is correct, it is necessary to control the injection amount at the appropriate time to obtain the best fuel consumption, but if the oxygen sensor is broken, the feedback to the computer will become the wrong information, and the best injection amount cannot be obtained. The life of the oxygen sensor is usually around 100,000 kilometers, which needs to be taken into account when the vehicle reaches such a number of kilometers
Activated carbon tank, the role of the activated carbon tank is to collect the gasoline vapor in the tank, the use of the physical adsorption of activated carbon, the gasoline molecules adsorbed on the activated carbon into the engine to burn and use. Then, if there is a problem with the activated carbon tank at this time, it may be blocked by the theft trachea. The symptom is that the car is difficult to start and has a pronounced smell of gasoline. In this case, check the activated carbon tank.
I hope that the majority of car owners cherish their favorite cars and do not be vague when they should be maintained.
