Why do you keep calling the police when the car doesn't catch fire?

If the car battery voltage is too low or fails, improper daily use of the car will lead to the loss of battery power. Generally speaking, the life of a battery is 3 to 5 years. If it exceeds this time limit, it needs to be replaced in time.

The fuel system is short of fuel supply and cannot reach the air-fuel ratio required by the engine. Check whether the fuel is sufficient, and the air-fuel ratio of the engine can't reach the required air-fuel ratio due to excessive carbon deposition in the intake pipe, throttle valve and idle motor. Checking idle driving and bad vehicle environment will accelerate carbon generation.

Matters needing attention in automobile start-up

During the unloading process, because the engine is in the cooling state, the operating parameters of the engine are completely different from the previous thermal state, and the sensor needs to be readjusted. If the owner directly inserts the key to start the engine, it will cause the engine to run with non-original data, leading to failure or multiple starts.

Even if it happens to start successfully, the engine will be damaged, such as excessive fuel consumption and excessive heat. In the long run, it will lead to the wrong data overwriting the original correct data over and over again. Subsequently, a series of failures occurred. Of course, the most serious thing is that even overhauling the engine will not help.
