The suction is caused by the turbocharger compressor wheel, which is used to compress the air. The air then flows through aftercooler (10) (if equipped). The aftercooler utilized sea water in order to cool the inlet air. Cooling of the inlet air causes the air to become more dense. This increases combustion efficiency and this increases horsepower output. The air flows from the aftercooler (if equipped) into inlet manifold (5) which directs an even distribution of the air to each engine cylinder. Air is pulled into the engine cylinder through inlet valve (9) during the intake stroke of the piston. Then, the air is mixed with fuel from the fuel injection nozzles. After the fuel combustion occurs, the exhaust gases flow out of the cylinder through exhaust valve (7). The exhaust gases then flow through exhaust manifold (6) and into the turbine side of turbocharger (3). The hot exhaust gases are used to drive the turbine inside the turbocharger. The turbine is used in order to drive the compressor wheel. The exhaust gases then exit the turbocharger through exhaust outlet (4) .Each piston makes four strokes:
Intake
Compression
Power
ExhaustThe sequence of the strokes by all of pistons in all of the engine cylinders provide constant air flow to the inlet system during the engine operation.Naturally Aspirated

The air flows from the inlet manifold to the engine cylinders. The fuel is mixed with the air in the engine cylinders. After the fuel combustion occurs in the engine cylinder, the exhaust gases flow through the exhaust manifold (6).

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
