ENGINE LUBRICATION SYSTEM

DESCRIPTION OF LUBRICATION SYSTEM

The rotor oil pump (1) at the front end of the
crankshaft sucks oil out of the oil pan (3) by
oil strainer (2) and pressurizes oil, and then
the pressurized oil will enter the full-flow oil
filter through the auxiliary oil passage (4) at
the left side of the cylinder(view from the
front). A relief valve (6) is set up inside the oil
pump to control the pressure at the main oil
passage. The relief
440kpa+20kpa, and the filtered oil flow from
the center hole in oil filter through the center
hole of the filter terminal to the engine main
oil passage.
The main oil passage lubricate the main
bearing through holes on the cylinder block
and lubricate the connecting-rod bearing
through the oil passage inside the crank shaft.
On the side of the vent pipe of the
connecting-rod bearing is a small oil hole
from where oil will eject to lubricate piston
pin and cylinder.
Oil pressure sensor (8) is close to oil filter,
connected to the main passage through an
internal oil passage. And engine oil will be
provided upward to the third camshaft journal
from the upper oil passage.
Other camshaft journals get oil from the
middle passage of the camshaft, whose ends
are sealed with steel balls.
