One of the basic knowledge of automobile engine maintenance has eight causes of engine failure:
Everyone has a heart. If the heart stops beating, life will disappear. The car is no exception. The engine is the heart of the car. The maintenance of the car directly affects the car's performance and its service life. In order to keep our car away from "heart disease," we must love the car's engine like caring for our own heart. The eight major factors that cause the vehicle to suffer from "heart disease" described below may benefit you.
Due to one, out of schedule maintenance
Usually people always like to invest a lot of money in the modification, but it is easy to ignore the maintenance of the engine on schedule. According to experienced auto mechanics, “In the cars they have repaired, the fault caused by the poor maintenance of the engine accounted for 50% of the total fault.†It can be seen that engine maintenance plays a key role in extending the service life of the vehicle. The role. Of course, it will also reduce unnecessary losses for you.
Due to Second, oil deterioration and oil filter is not smooth
Different grades of lubricating oil will change during use. After the vehicle has traveled a certain distance, the performance will deteriorate, which may cause various problems for the engine. In order to avoid the occurrence of these failures, the vehicle should be regularly replaced with the conditions of use, and the amount of oil should be moderate, generally between the upper and lower limits of the oil. When the oil passes through the pores of the oil filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and the oil cannot smoothly pass through the filter element, it will burst the filter element or open the safety valve. Passing the bypass valve will still bring dirt back to the lubrication area, which will accelerate engine wear and increase internal pollution. Therefore, regular replacement of oil filter elements is equally important.
Because of three, air filter plug
The air intake system of the engine is mainly composed of an air filter element and an intake port. According to different use conditions, to regularly clean the air filter, the method can be used to blow high pressure air from the inside, the dust in the filter element is blown out. Since the air filter is paper, it should be noted that the air pressure should not be too high when blowing so as not to damage the filter element. The air filter should be replaced after 3 times of cleaning. The cleaning cycle can be determined by the air quality of the daily driving area.
Due to four, the intake pipe is dirty
If the vehicle is often driving in a road with a lot of dust and poor air quality, it should pay attention to cleaning the air intake pipe to ensure the smooth flow of air. The intake pipe is very important for the normal operation of the engine. If the intake pipe is dirty, the charging efficiency will decrease, and the engine will not be able to operate within the normal output power range, which will aggravate engine wear and aging.
Cause five, excessive crankshaft sludge
During the operation of the engine, the high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, mixing it with the metal powder produced by the wear of the components. Together, sludge is formed. A small amount of sludge can be suspended in the oil and when it equates to a large amount, it precipitates out of the oil, clogging the filter and the oil hole, causing the engine to be difficult to lubricate, thereby aggravating engine wear. In addition, when the oil is oxidized at a high temperature, a paint film and coke deposits are formed on the piston, so that the engine oil consumption increases and the power drops. In severe cases, the piston ring is stuck and the cylinder is pulled.
Due to six, poor maintenance of the fuel system
The maintenance of the fuel system includes replacing the fuel filter, cleaning the carburetor or fuel nozzle, and the oil supply line. During the combustion of fuel oil through the oil circuit to the combustion chamber, it will inevitably form colloid and carbon deposits. It will be deposited in oil passages, carburetors, fuel injectors, and combustion chambers, interfering with the flow of fuel and damaging the oil. The air-fuel ratio causes poor fuel atomization, causing engine performance problems such as engine vibration, knocking, unstable idling, and poor acceleration. Using fuel system cleaners to clean the fuel system will always keep the engine in top condition.
Due to seven, water tank rust, scaling
Rust and scaling of engine tanks are the most common problems. The rust and scale will limit the flow of coolant in the cooling system, reduce the heat dissipation, cause the engine to overheat, and even cause damage to the engine. Coolant oxidation also forms acidic substances that corrode the metal parts in the tank, resulting in breakage and leakage of the tank. Regular use of water tanks for powerful and efficient cleaning agents to clean water tanks to remove rust and scale from them will not only ensure normal operation of the engine, but also extend the overall life of the tank and engine.
Due to poor cooling system conditions
People pay more attention to the maintenance of automobile engines, lubrication systems, and rarely pay attention to cooling systems. Little does they know the most common failures of automotive engines, such as piston pull, knock, internal leakage of cylinder block, serious noise, deceleration of acceleration, and so on, all due to the abnormal working temperature of automobile engine, excessive pressure, and the status of cooling system Bad result. The poor condition of the cooling system will directly lead to the engine not being able to work at the normal temperature, which will result in the above-mentioned serious failure phenomenon.
