General Information
This engine is the forced lubrication type of engine. Oil pres-
sure is generated and delivered by rotating the gear of the oil
pump which is directly engaged with the crankshaft gear on
the front of the cylinder block.
The oil pump delivers oil sucked from the oil pan with the
suction pipe to the main path of the cylinder block through the
oil cooler and oil filter.

From the cylinder block, oil is delivered to the crankshaft
bearings, camshaft bearings, and rocker arm for lubrication.
In addition, the turbocharger is connected to the engine lubri-
cation circuit. Around the cylinder block and the timing gear,
lubricating oil is dispersed. Each cylinder has an oil injection
nozzle for cooling the bottom of the piston. Engine oil is
filtered through the oil filter and purified.
