Throttle Body
Figure4-5
Figure4-6
The throttle body controls the operating speed of the
engine according to input from the ECM. Defaults
programmed into the ECM software, along with throttle
position sensors, allow the ECM to control the overall
operation of the engine in response to changing
speeds and loads.
Turbocharger
Figure4-7
The Model KG2204T engine is equipped with a
turbocharger. The turbocharger utilizes exhaust gas
flowing through the turbine to spin a compressor. The
turbocharger compressor increases boost pressure
and density of the air/fuel mixture entering the intake
manifold resulting in higher power output compared to
the naturally aspirated engine. A wastegate on the
turbocharger bypasses exhaust gas around the turbine
when the boost pressure reaches a maximum limit.
Turbocharger Oil Lines
The Model KG2204T engine is equipped with a
turbocharger. The turbocharger bearings require oil for
lubrication and cooling. Oil is fed to the turbocharger
bearings from the oil supply line on the top side of the
bearing housing and returned to the oil sump through a
line connecting the bottom side of the bearings to the
sump.
Charge Air Cooler
Figure4-8
The Model KG2204T engine is equipped with a charge
air cooler. The charge air cooler (A) cools the
compressed air/fuel mixture before it enters the intake
manifold. The cooler intake manifold charge helps
maintain emissions at the high power level of the
turbocharged engine.
