Air inlet system and exhaust system (1) Exhaust manifold (2) Aftercooler (3) Engine cylinder (4) Air inlet (5) Turbocharger compressor wheel (6) Turbocharger turbine wheel (7) Exhaust outletThe engine components of the air inlet system and exhaust system control the quality of air that is available for combustion. These components also control the amount of air that is available for combustion. An air cleaner, a turbocharger and an exhaust manifold are on each side of the engine. A common aftercooler is located between the cylinder heads and toward the rear of the engine. The inlet manifold is a series of passages inside the cylinder block. These passages connect the aftercooler to the inlet ports in the cylinder heads. A single camshaft is located in the cylinder block. The camshaft controls the movement of the valve system components.Both sides of the engine have the same air flow. Turbocharger compressor wheel (5) pulls inlet air through the air cleaner and into air inlet (4). The air is compressed and heated before the air is forced to the aftercooler (2). The aftercooler (2) lowers the temperature of the compressed air. The cooled compressed air passes through the inlet manifold. The air fills the inlet ports in the cylinder heads. Air flow from the inlet port into the cylinder is controlled by the inlet valves. The combustion efficiency increases because of the cooler inlet air. This helps to provide lowered fuel consumption and increased horsepower output.Each cylinder has two inlet valves and two exhaust valves in the cylinder head. The inlet valves open when the piston moves downward on the inlet stroke. When the inlet valves open, cooled compressed air from the inlet chamber within the inlet manifold is pulled into the cylinder. The piston begins to move up on the compression stroke when the inlet valves close. The air in the cylinder is compressed and the fuel is injected into the cylinder when the piston is near the top of the compression stroke. Combustion begins when the fuel mixes with the air. The force of combustion pushes the piston downward on the power stroke. The exhaust valves open and the exhaust gases are pushed through the exhaust port into exhaust manifold (1). After the piston makes the exhaust stroke, the exhaust valves close and the cycle begins again.Exhaust gases from the exhaust manifold (1) flow into the turbine side of the turbocharger. This causes turbocharger turbine wheel (6) to turn. The turbine wheel is connected to the shaft that drives the compressor wheel. Exhaust gases from the turbocharger pass through the exhaust outlet (7). Series Turbocharger Arrangement

A single camshaft is located in the cylinder block. The camshaft controls the movement of the valve system components.Both sides of the engine have the same air flow. Air is pulled through the low pressure turbocharger air inlet (7). The air is compressed and heated by the compressor wheel (8) of the low pressure turbocharger. The compressed air is then directed through pipe assembly. The air flows to the high pressure turbocharger air inlet (3) of the high pressure turbocharger. The high pressure turbocharger compressor wheel (4) continues to compress the air. The air is forced into the aftercooler (2). The aftercooler (2) lowers the temperature of the compressed air.

Aftercooler (1) Aftercooler (2) PipeThe aftercooler (1) cools the air that comes from the turbochargers. The air then flows into the inlet manifold. The aftercooler is located toward the rear of the engine between the cylinder heads. Coolant from the
