my tachometer stopped working

Why my tachometer stopped working? Let us find the reasons.

In order to avoid the occurrence of these faults, the oil should be changed regularly in combination with the service conditions, and the oil volume should be moderate. Generally, it is better to be between the upper and lower limits of the oil scale. When the engine oil passes through the fine hole of the engine oil filter element, the solid particles and viscous substances in the oil are accumulated in the filter. If the filter is blocked and the oil cannot pass through the filter element smoothly, the filter element will be broken or the safety valve will be opened to pass through the bypass valve, and the dirt will still be brought back to the lubrication part, accelerating the wear of the engine and increasing the internal pollution. Therefore, regular replacement of the oil filter element is equally important.

Since the air filter element is made of paper, pay attention to the air pressure when blowing, so as not to damage the filter element. Generally, the air filter element should be replaced with a new one after cleaning for 3 times. The cleaning cycle can be determined by the air quality in the daily driving area.

The intake duct is very important for the normal operation of the engine. If the intake duct is too dirty, it will lead to the decline of inflation efficiency, so that the engine can not operate within the normal output power range, and aggravate the wear and aging of the engine.

In addition, when the engine oil is oxidized at high temperature, paint film and carbon deposit will be generated and bonded to the piston, which will increase the fuel consumption and reduce the power of the engine. In serious cases, the piston ring will be stuck and the cylinder will be pulled.

The oxidation of coolant will also form acidic substances, which will corrode the metal parts in the water tank, resulting in damage and leakage of the water tank. Regular use of strong and efficient cleaning agent to clean the water tank to remove rust and scale can not only ensure the normal operation of the engine, but also prolong the overall service life of the water tank and the engine.

The poor condition of the cooling system will directly lead to the engine not working at normal temperature, followed by the above serious faults.

These reasons all can make the tachometer stopped working, need to check one by one.
