A variable oil discharge volume trochoid gear type oil pump assembly is used.
In the low- and high-speed ranges, the oil pump provides the oil pressure that is necessary for operating the VALVEMATIC, Dual VVT-i and lubrication systems. In the medium-speed range, the surplus oil pressure has been reduced in order to reduce friction.
