9.1 DESCRIPTION AND OPERATION OF THE DD13 TURBOCHARGER
AND RELATED PARTS
Compression of air in the turbocharger causes an air mass to fl ow into the combustion chamber.
The turbocharger consists of a turbine and a compressor which are attached to a shaft. The
exhaust gas
fl ows to the turbine wheel and causes it to turn. This turning motion is transmitted
to the shaft and the compressor impeller. The intake air from the air fi lter is compressed by the
compressor impeller and fl ows over a charge air pipe to the charge air cooler. The compressed air
is cooled in the charge air cooler, permitting a more dense charge of air to be delivered to the
engine, and therefore, engine output is increased. The charge air then passes from charge air
cooler into the intake manifold. The turbocharger is mounted on the exhaust outlet
fl ange of the
engine exhaust manifold.
The turbocharger is mounted on the exhaust outlet fl ange of the engine exhaust manifold.
The advantages are as follows:
□ Increases the engine performance and torque
□ Reduction of the fuel consumption compared to a similarly powered naturally aspirated
engine
□ Reduction of emissions.
