(8) Compressor side of turbocharger
(9) Turbine side of turbocharger The components of the air inlet and exhaust system control the quality of air and the amount of air that is available for combustion. The components of the air inlet and exhaust system are the following components:
Air cleaner
Turbocharger
Aftercooler
Cylinder head
Valves and valve system components
Piston and cylinder
Exhaust manifold Inlet air is pulled through the air cleaner into air inlet (6) by turbocharger compressor wheel (8). The air is compressed and heated to about 150 °C (302 °F) before the air is forced to the aftercooler (3). As the air flows through the aftercooler the temperature of the compressed air lowers to about 43 °C (109 °F). Cooling of the inlet air increases combustion efficiency. Increased combustion efficiency helps achieve the following benefits:
Lower fuel consumption
Increased horsepower outputFrom the aftercooler, air is forced into the inlet manifold. Air flow from the inlet chambers into the cylinders is controlled by inlet valves (5). There are two
