ENGINE COMPONENT DESCRIPTION
Oil pump – standard oil pump
The oil pump draws engine oil from the oil pan and feeds it under pressure to the
various parts of the engine. When the crankshaft rotates, the oil pump drive gear
rotates. This causes the space between the gears to constantly open and narrow,
pulling oil in from the oil pan when the space opens and pumping the oil out to the
engine as it narrows. At high engine speeds, the oil pump supplies a much higher
amount of oil than required for lubrication of the engine. The oil pressure regulator
prevents too much oil from entering the engine lubrication passages.
Turbocharger
The turbocharger supplies compressed hot air that is created from exhaust
gas that passes the turbocharger’s exhaust turbine driving the induction side
turbine increasing airflow to the engine thus increase the power. A water-cooled
intercooler is used before compressed hot air enters the engine in order to lower
the temperature of the induuce air for optimum power for the combustion process.
During normal engine operation water will flow through the turbocharger’s center
housing due to pressure created by the engine’s water pump. After the engine is
shut off and the water pump is no longer pumping, a ‘thermal siphoning’ pulls
water through the turbocharger’s center housing.
Valves
There are 2 intake and 2 exhaust valves per cylinder with “minilash” hydraulic
adjusters with roller fingers.
Valve lash adjusters
The valve train uses a roller finger follower acted on by a hydraulic lash adjuster.
The roller finger follower reduces friction and noise.
