What is the reason for the flameout of 465 engine with high-speed injection of cleaning agent?

Second, oil deterioration and poor oil filter.

The oil 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, it is necessary to change the oil of the car regularly according to the use situation, so that the oil quantity is moderate, generally between the upper limit and the lower limit of the oil meter.

When the oil passes through the pores of the oil filter element, solid particles and viscous substances in the oil will accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element smoothly, the filter element will burst or the safety valve will be opened, and the dirt will still be brought back to the lubrication part through the bypass valve, which will accelerate the engine wear and increase internal pollution. Therefore, it is equally important to change the oil filter regularly.

Because three, the air filter is blocked.

The intake system of an engine is mainly composed of an air filter element and an intake passage. According to different use conditions, the air filter element should be cleaned regularly. Available methods include blowing high-pressure air from the inside out to blow out the dust in the filter element. Because the air filter element is paper, pay attention to the air pressure when blowing to avoid damaging the filter element. Generally, the air filter element should be replaced after three cleanings, and the cleaning cycle can be determined according to the air quality in the daily driving area.

Due to four, the intake pipe is too dirty.

If the vehicle often travels on dusty roads with poor air quality, attention should be paid to cleaning the intake pipe to ensure smooth intake. The intake pipe is very important for the normal operation of the engine. If the intake pipe is too dirty, the charging efficiency will be reduced, so that the engine can not work within the normal output power range, which will aggravate the wear and aging of the engine.

There is too much sludge in the crankcase.

During the operation of the engine, high-pressure unburned gas, acid, water, sulfur and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, so that they are mixed with the metal powder produced by the wear of parts to form sludge. A small amount of sludge can be suspended in the engine oil. When the equivalent is large, it will be separated from the engine oil, blocking the filter and oil hole, making it difficult to lubricate the engine, thus aggravating the engine wear. In addition, the oxidation of engine oil at high temperature will produce paint film and carbon deposit, which will stick to the piston, increase fuel consumption, reduce engine power, and even make the piston ring jam and pull the cylinder seriously.

6. Poor maintenance of fuel system.

The maintenance of the fuel system includes replacing the gasoline filter element, cleaning the carburetor or fuel nozzle and the oil supply pipeline. When the fuel is supplied to the combustion chamber through the fuel passage, it will inevitably form colloid and carbon deposit in the fuel passage, carburetor, nozzle and combustion chamber, which will interfere with the fuel flow, destroy the normal air-fuel ratio, cause poor fuel atomization, and cause engine jitter, knock, unstable idle speed, poor acceleration and other performance problems. Cleaning the fuel system with fuel system cleaning agent can always keep the engine in the best condition.

Due to seven, water tank rust, scaling.

Rusting and scaling of engine water tank are the most common problems. Rust and scale will limit the flow of coolant in the cooling system, reduce the heat dissipation effect, lead to overheating of the engine and even cause engine damage. Oxidation of cooling liquid will also form acidic substances, which will corrode the metal parts in the water tank, resulting in water tank damage and water leakage. Regular use of powerful and efficient water tank cleaning agent can not only ensure the normal operation of the engine, but also prolong the overall life of the water tank and engine.

Eight, the cooling system is in poor condition.

In the maintenance of automobile engines, people pay special attention to the lubrication system and seldom pay attention to the cooling system. I don't know the most common faults of automobile engine, such as piston cylinder pulling, knocking, internal leakage of cylinder block punch, serious noise, decreased acceleration power, etc. All of them are caused by abnormal working temperature, excessive pressure and poor cooling system of automobile engine. The poor condition of the cooling system will directly lead to the failure of the engine to work at room temperature, which will lead to the above-mentioned serious failure phenomenon.
