e. Air Intake System. Air intake system includes an air cleaner, turbocharger (6), intake manifold (7) and

connecting piping. Purpose of air intake system is to provide a supply of clean, pressurized air for fuel

combustion in the engine cylinders. Turbocharger rotation draws air through the air cleaner, where most

airborne contaminants are removed, and forces this air, under pressure into the intake manifold. From the

intake manifold, air is distributed to the cylinders through timing action of the intake valves.

f. Exhaust System. Exhaust system includes exhaust manifold (8), turbocharger turbine (9), exhaust

piping, and muffler. Exhaust gases are directed against the turbine blades, causing turbine to rotate at high

speed. Exhaust gases leaving turbocharger pass through the muffler, which reduces level of exhaust noises.
