Air inlet and exhaust system (1) Exhaust manifold (2) Fuel injection nozzle (3) Glow plug (4) Inlet manifold (5) Exhaust outlet (6) Turbocharger turbine wheel (7) Turbocharger compressor wheel (8) Air inlet (9) Inlet valve (10) Engine cylinder (11) Exhaust valveThe components of the air inlet and exhaust system control the quality of air and the amount of air that is available for combustion. The air inlet and exhaust system consists of the following components:
Air cleaner
Turbocharger
Inlet manifold that is integral with the cylinder head
Cylinder head, injectors and glow plugs
Valves and valve system components
Piston and cylinder
Exhaust manifoldAir is drawn in through the air cleaner into the air inlet of the turbocharger (8) by the turbocharger compressor wheel (7). The air is compressed and heated.Air is forced into the inlet manifold (4). Air flow from the inlet manifold to the engine cylinders (10) is controlled by the inlet valves (9). There is one inlet valve and one exhaust valve (11) for each cylinder. The inlet valve opens when the piston moves down on the intake stroke. When the inlet valve opens, compressed air from the inlet port is forced into the cylinder. The complete cycle consists of four strokes:
Inlet
Compression
Power
ExhaustOn the compression stroke, the piston moves back up the cylinder and the inlet valve (9) closes. The air is compressed and this compression generates more heat.Note: If the cold starting system is operating, the glow plugs (3) will also heat the air in the cylinder.Just before the piston reaches the TC position, fuel is injected into the cylinder via the fuel injection nozzle (2). The air/fuel mixture ignites. The ignition of the gases initiates the power stroke. Both the inlet and the exhaust valves are closed and the expanding gases force the piston downward toward the bottom center (BC) position .From the BC position, the piston moves upward. This initiates the exhaust stroke. The exhaust valve (11) opens. The exhaust gases are forced through the open exhaust valve into the exhaust manifold (1) .Exhaust gases from exhaust manifold (1) enter the turbine side of the turbocharger in order to turn turbocharger turbine wheel (6). The turbocharger turbine wheel is connected to the shaft that drives the turbocharger compressor wheel (7). Exhaust gases from the turbocharger, pass through the exhaust outlet (5), and an exhaust pipe and a silencer.Naturally Aspirated Engines

Note: The turbocharger is not serviceable.A turbocharger increases the temperature and the density of the air that is sent to the engine cylinder. This condition causes a lower temperature of ignition to develop earlier in the compression stroke. The compression stroke is also timed in a more accurate way with the fuel injection. Surplus air lowers the temperature of combustion. This surplus air also provides internal cooling. A turbocharger improves the following aspects of engine performance:
Power output is increased.
Fuel efficiency is improved.
Engine torque is increased.
Durability of the engine is improved.
Emissions from the engine are reduced.

Typical exampleComponents of a turbocharger (typical example) (1) Air inlet (2) Compressor housing (3) Turbocharger compressor wheel (4) Bearing (5) Oil inlet port (6) Bearing (7) Turbine housing (8) Turbocharger turbine wheel (9) Exhaust outlet (10) Oil outlet port (11) Exhaust inletA turbocharger is installed between the exhaust and inlet manifolds. The turbocharger is driven by exhaust gases which flow through the exhaust inlet (11). The energy of the exhaust gas turns the turbine wheel (8). Then, the exhaust gas flows out of the turbine housing (7) through the exhaust outlet (9) .The turbocharger turbine wheel and the turbocharger compressor wheel (3) are installed on the same shaft. Therefore, the turbocharger turbine wheel and the turbocharger compressor wheel rotate at the same rpm. The turbocharger compressor wheel is enclosed by the compressor housing (2). The turbocharger compressor wheel compresses the air that is drawn in from the air intake (1). The air flows into the engine cylinders through the inlet valves of the cylinders.The oil from the main gallery of the cylinder block flows through the oil inlet port (5) in order to lubricate the turbocharger bearings (4) and (6). The pressurized oil passes through the bearing housing of the
