Cummins Engine Parts M11 Oil Pump 4003950 Diesel Engine Parts

Specification

Effect

The function of the oil pump is to pressurize the oil in the oil pan to the oil filter and lubricating oil passages to lubricate the main moving parts of the engine and to filter the oil. When the engine is working, the oil pump works continuously to ensure that the oil circulates in the lubricating oil circuit continuously. The oil pump should ensure sufficient lubricating oil under various operating conditions of the engine. Since the speed of the oil pump is directly proportional to the engine speed, the oil pump has the worst oil supply capacity at low speeds. Therefore, the design should consider that the oil pump has sufficient oil supply at low speeds.
