What is a car oil pump
Automobile oil pump is a device that draws fuel from the tank and transmits it to the engine through the pipeline. Its main function is to provide a certain fuel pressure for the fuel system to ensure that the fuel can reach the engine and drive the car smoothly. Automobile oil pump according to different driving methods are divided into mechanical drive diaphragm type and electric drive type. The mechanically driven diaphragm type oil pump relies on the eccentric wheel on the camshaft to drive the fuel to the engine through the process of oil suction and oil pumping; The electric driven oil pump repeatedly draws the pump film through the electromagnetic force, which has the advantages of flexible installation position and anti-air resistance.
The importance of automobile oil pump in the automobile is self-evident, and its quality and working condition directly affect the fuel injection, fuel injection quality, power and fuel economy of the vehicle. If the oil pump is damaged, it will cause the engine to be difficult to start, poor acceleration or weak operation. Therefore, regular inspection and maintenance of the car oil pump is an important measure to ensure the normal operation of the vehicle.
The main role of the car oil pump includes pumping fuel from the tank and pressurizing it to the engine's fuel injection nozzle to ensure the normal operation of the engine. In particular, the oil pump transfers fuel to the supply line by pressurizing it and works with the fuel pressure regulator to build up a certain fuel pressure to continuously supply fuel to the nozzle and ensure the engine's power requirements.
Types of oil pumps include fuel pumps and oil pumps. The fuel pump is mainly responsible for extracting the fuel from the tank and pressurizing it to the fuel injection nozzle of the engine, while the oil pump extracts the oil from the oil pan and pressurizes it to the oil filter and each lubricating oil passage to lubricate the main moving parts of the engine.
The fuel pump is usually located inside the vehicle's fuel tank and works when the engine is started and running. It sucks the fuel from the tank through centrifugal force and pressurizes it to the oil supply line, and works with the fuel pressure regulator to establish a certain fuel pressure. Through the working principle of gear type or rotor type, the oil pump uses the volume change to change the low pressure oil into high pressure oil to lubricate the main moving parts of the engine.
