A compact cycloid rotor type oil pump directly driven by the crankshaft is used.
This oil pump uses an internal relief method which circulates relief oil to the oil passage in the oil pump. This aims to minimize oil level change in the oil pan, reduce friction, and reduce the air mixing rate in the oil.
