Oil pumps are forced feed to oil to each friction surface under raising oil pressure and ensuring engine oil capacity.
Oil pumps are divided into Rotor Oil pumps and Gear Oil pumps. Most of automotive oil pumps are gear pumps. When the car`s engine begins to work, the engine shaft drives the oil pump gear. In high speed operation, it forms a strong positive and negative pressure around the internal and external of oil pump, and the oil is sucked by oil pump, pressuring to the engine parts, so as to realize a kind of compulsory lubrication. And oil pump, here, increase the internal and external pressure difference. The faster the speed, the greater the pressure, and the lube oil floe is faster, more comfortable car run up.
