ENGINE LUBRICATION SYSTEM
M MECHANISM AND FUNCTION
1 . General
The lubrication system is a full-flow, filtering type . The
oil pump utilizes a thin, large-diameter trochoid design
to accommodate the high engine output . It is directly
driven by the crankshaft .
Engine oil flow is regulated by the relief valve built into
the oil pump . Then oil flows to the oil filter via the oil
passage on the lower right side of cylinder block. After
filtered the oil filter, engine oil delivered to the crank
journal bearings via the oil gallery on the cylinder block
and then delivered to the connecting rod bearing via the
crank journal.
Engine oil is also fed under pressure to the cylinder
head valve mechanism after the flow is regulated by the
orifice provided in the oil gallery.
The oil pan is provided with baffle plates to eliminate
the effect of oil suction caused by oil level variations
during operation .
