Basic knowledge of automobile engine maintenance

Eight engine failures are mainly because everyone has a heart. If the heart stops beating, life will disappear. The automobile is no exception, the engine is the heart of the automobile, and the quality of maintenance directly affects the performance and service life of the automobile. In order to keep the car away from the "heart", take care of your heart and the engine of the car for us. Eight is suffering from heart disease leading to the vehicle described below, which is possible, so if you have a benefit.

First, no maintenance will be arranged.

Usually, people always like to invest a lot of money in modification, but it is easy to ignore the engine that is regularly maintained. The experience of car maintenance master said: "In dealing with car maintenance, 50% of the total failures caused by vehicle failures are caused by poorly maintained engines." It can be seen that the maintenance of the engine can play a vital role in prolonging the service life of the vehicle. Courses will reduce unnecessary losses for you, or how can the word "improve maintenance" stand for it?

It is because the two major oils have deteriorated and the oil filter is not good.

The quality of different grades of lubricating oil will change during use. After a certain mileage, the performance of the vehicle will deteriorate, which may bring various problems to the engine. In order to avoid these failures, we should change the oil meter between the upper limit and the lower limit regularly and use it jointly under the condition of automobile oil and oil medium. Oil is collected from the filter of the hole of the oil filter by solid particles and viscous oil. If the filter is blocked, the oil can't pass through the bypass valve or open the safety valve to pass through the filter screen of the filter, and it is still the lubrication part of dirt, which will accelerate the wear of the engine and increase internal pollution. Therefore, it is equally important to change the oil filter regularly.

It's because the air filter is blocked

The air filter is mainly composed of two parts and the intake system of the intake engine. According to different situations, clean the air filter regularly, and use high-pressure air to blow the dust off the filter from the inside out. Pay attention to the air pressure when blowing air filter paper to avoid damaging the filter. Generally, air filters should be cleaned three times before replacement. The cleaning cycle can be determined according to the air quality in the daily driving area.

Because the intake pipe is too dirty

Vehicles often travel in dusty traffic areas with poor air quality. You should pay attention to cleaning the inlet of the intake pipe to ensure smooth flow. When the engine is running normally, it is very important to use the intake pipe. If the intake pipe is too dirty, the efficiency of the inflator will be reduced, so that the engine can not work in the normal output power range, and the wear and aging of the engine will be aggravated.

Too much sludge in the crankcase is due to

During the operation of the engine, unburned gas, acid, water, sulfur and nitrogen oxides in the combustion chamber enter the high pressure of the crankcase through the gap between the piston and the cylinder wall, mix with metal powder, and the generated parts wear together to form sludge. When suspended in engine oil and separated from engine oil, a small amount of sludge is heavy, which blocks the filter and oil hole, making engine lubrication difficult, thus increasing engine wear. In addition, the high-temperature oxide film produced by petroleum and the coke bonded piston increase the fuel consumption of the engine, reduce the power, and cause serious piston ring seizure and cylinder pulling.

6. Poor maintenance and management of fuel system

Maintenance of fuel system, including replacing fuel filter, cleaning carburetor or fuel nozzle and oil pipeline. Fuel inevitably forms a rubber and coke combustion chamber through the oil passage, which is deposited in the oil passage, carburetor, injector and combustion chamber, and interferes with the fuel flow and interrupts the normal air-fuel ratio, resulting in poor fuel atomization, engine breathing sloshing, knocking, unstable idle speed, poor acceleration and other performance problems. Fuel system cleaning agent cleans the fuel system, and the engine is always in the best condition.

Factor seven, the water tank rusts and scales.

Rust and scaling are the most common problems in the engine box. Rust and scale will limit the flow of coolant in the cooling system, reduce the cooling effect, lead to overheating of the engine and even cause engine damage. It is also the corrosion of the metal parts in the water tank caused by the formation of acidic substances, which leads to the damage of the water tank and the oxidation of the leaked cooling liquid. Frequent use of powerful and efficient water tank cleaning agent to clean the water tank and remove rust and scale can not only ensure the normal operation of the engine, but also prolong the overall life of the water tank and the engine.

Due to harsh conditions 8, the cooling system

People pay special attention to the protection of automobile engine lubrication system, but pay little attention to cooling system. I don't know that the most common faults of automobile engine are piston cylinder, cylinder body knocking, perforation, air leakage, serious noise, acceleration, power failure, abnormal working temperature of automobile engine, excessive pressure, or incorrect cooling system state. The poor condition of the cooling system will directly lead to the failure of the engine to work at normal temperature, and then serious failure will occur.
