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 manifoldThe turbocharger compressor wheel pulls inlet air through the air cleaner and into the air inlet. The air is compressed and this causes the air to become hot. The air flows through aftercooler core (2) and the temperature of the compressed air lowers. This helps to provide increased horsepower output. Aftercooler core (2) is a separate cooler core that is mounted in front of the engine radiator. The engine fan causes ambient air to move across both cores. This cools the turbocharged inlet air and the engine coolant.Air is forced from the aftercooler into inlet manifold (1) . The air from the inlet port into the cylinders is controlled by inlet valves.

Air inlet and exhaust system (Typical example) (2) Aftercooler core (4) Exhaust outlet (5) Turbine side of turbocharger (6) Compressor side of turbocharger (8) Exhaust manifold (9) Exhaust valve (10) Inlet valve (11) Air inletEach cylinder has two inlet valves (10) and two exhaust valves (9) in the cylinder head. The inlet valves open on the inlet stroke. When the inlet valves open, compressed air from the inlet port within the inlet manifold is pushed into the cylinder. The inlet valves close when the piston begins the compression stroke. 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 on the power stroke. The exhaust valves open and the exhaust gases are pushed through the exhaust port into exhaust manifold (8) . After the piston finishes the exhaust stroke, the exhaust valves close and the cycle begins again.Exhaust gases from the exhaust manifold flow into the turbine side of turbocharger (5) . The high temperature exhaust gases cause the turbocharger turbine wheel to turn. The turbine
