Question:

Is the engine speed the same as the pump speed?

Is the engine speed the same as the pump speed?

Answer:

No, the ratio is 2:1. The oil pump turns two times and the engine turns around
No, the ratio is 2:1. The oil pump turns two times and the engine turns around
No. the speed ratio between the engine and the oil pump is 2:1. That is to say, when the engine rotates, the two turns of the pump rotate. The principle is that the engine completes the intake, compression, work, exhaust, the four useful hours to rotate two times. The oil pump works only when it is done. So, just one lap would do.
