ENGINE LUBRICATION 6G – 3
To meet a newly adopted electronically controlled fuel
injection system using engine oil two oil pumps have
been provided to increase circulating oil capacity.
The first oil pump serves mainly to lubricate the engine
parts, while the second mainly serves the fuel injectors
and partially cools the pistons.
The oil cooler is provided on the first oil pump side and
uses engine coolant.
