Engine high-pressure pump: the importance and Comprehensive customs ruling databasemaintenance method Engine high-pressure pump is a very important part of modern fuel systems.In part, its function is to inject fuel into the fuel injector in a high-pressure manner. When the engine is working normally, the high-pressure pump is responsible for providing a stable fuel supply to the engine. Therefore, the performance and reliability of the engine high-pressure pump have a key impact on the performance and reliability of the whole engine. This article will introduce the importance of engine high-pressure pumps and their maintenance methods. I. The importance of engine high-pressure pump 1. The relationship between engine high-pressure pump and engine performance. Engine high-pressure pump is an important component to control the fuel injection volume and injection pressure of the engine. When working, the high-pressure pump connects the fuel to the electric nozzle through the high-pressure injection pipe, and then injects the fuel into the combustion chamber at high pressure and high speed. The performance and reliability of the engine high-pressure pump can directly affect the work efficiency and performance of the engine. Two. BurnThe relationship between oil pump and fuel consumption. The high-pressure fuel produced by the engine high-pressure pump helps the engine achieve efficient combustion and reduce fuel waste, thus achieving lower fuel consumption. Therefore, the impact of the working status of the engine high-pressure pump on fuel economy is crucial. 3. The relationship between engine high-pressure pump and emissions. Engine high-pressure pump also affects the emission level. The high-pressure fuel injection of the high-pressure pump can make the engine burn more fully, thus reducing emissions. Therefore, the performance and reliability of high-pressure pumps play an important role in reducing harmful gas emissions. II. Maintenance method of engine high-pressure pump 1. Regular replacement of fuel filters is an important protective measure to prevent damage to high-pressure pumps. Therefore, it is recommended to check and replace the fuel filter regularly when using the engine. In addition, do not be mixed with too many foreign objects in the oil pipeline, otherwise it will cause damage to the fuel filter and high-pressure pump.Two. Correct refueling and the use of clean fuel can effectively extend the service life of the high-pressure pump. The use of unclean oil will increase the wear and damage of the high-pressure pump, which will cause the high-pressure pump to fail completely in serious cases. Therefore, it is recommended to use high-quality fuel when refueling and avoid using oil that cannot be cleaned. 3. After the high-pressure pump of the cylinder block engine is stored for a period of time, rust or sediment may occur between the plunger and the pump body, causing the high-pressure pump to fail to work properly. Therefore, it is recommended that before using the high-pressure pump, use an oil heater to heat the fuel and gently rotate the pump body to flush out the dirt stored in the cylinder, such as rust and slag. Four. Pay attention to the temperature of the high-pressure pump. When the engine high-pressure pump is used in a high-temperature environment, it will produce thermal expansion. When it is serious, it will jam the plunger, resulting in the failure of the high-pressure pump. Therefore, when the engine is running at high load for a long time, you should pay attention to check the temperature of the high-pressure pump to avoid burning the high-pressure pump at high temperatures.Conclusion: Engine high-pressure pump is a very important part of the modern fuel system, and its performance and reliability have a key impact on the performance and reliability of the whole engine. Through the maintenance methods introduced above, it can effectively extend the service life of the high-pressure pump and reduce the failure rate, ensure the normal operation of the engine, reduce the cost of maintenance and replacement, and improve efficiency.
