How to evaluate supplier reliability

Diesel engine accessories: important diesel engine components diesel engines are How to evaluate supplier reliabilitywidely used in many heavy vehicles, agricultural machinery, engineering machinery, generator sets and other fields. Its structure is complex, contains a wide variety of accessories, and the functions of each accessory are also different. Some of these accessories are very important and have a decisive impact on the performance and life of the engine. This article will introduce the important accessories of diesel engines and their functions. 1. Fuel injector The fuel injector is a very important spare part in a diesel engine. Its function is to spray the oil mist into the cylinder, mix it with air and burn it, so as to push the piston and drive the engine to work. The working quality of the injector and the high or low injection pressure have a great impact on the performance and fuel consumption of the engine. Two. Turbocharger TurbochargerThe device, also known as the turbocharger, is used to improve the intake pressure and intak density of the diesel engine, and to increase the output power and torque of the engine. The existence of turbochargers can enable the engine to maintain high output power and torque at high speed, which increases the utilization rate and work efficiency of the engine. 3. Valve system The valve system in diesel engine includes components such as intake pipe, intake valve, exhaust pipe and exhaust valve. Its main function is to control the intake and exhaust of the engine to ensure the smooth and stable operation of the engine. For high-performance diesel engines, the valve system is particularly important, which directly determines the output capacity and stability of the engine. Four. Fuel pump Fuel pump is an important part of the diesel engine used to transport fuel. Its function is to draw the fuel out of the fuel tank and transport it to the injector after filtration and boosting.The operating quality and adjustment accuracy of the fuel pump have an important impact on the fuel economy and emission efficiency of the engine. 5. Starter starter is the starting device of a diesel engine. Its main function is to drive the crankshaft to rotate through the power output by the motor, so as to realize the start of the engine. The starter is usually installed on the side or bottom of the engine, and its reliability and performance directly affect the service life and efficiency of the whole engine. 6. Water pump is a cooling system in a diesel engine. Its main function is to transfer water and coolant to the radiator, lower the temperature of the engine, and discharge heat out of the car. The performance of the water pump directly determines the service life and efficiency of the engine under high temperatures and high loads. The above accessories are very important spare parts in diesel engines. They have different functions, but they all have a decisive impact on the performance and life of the engine.Therefore, once these accessories have an abnormal failure or poor performance, they need to be repaired or replaced in time to ensure the normal operation of the engine.
