A major difference between a turbo diesel engine and its naturally aspirated counterpart is the increase in power that is derived from a turbocharger. This results from an increase in the amount of air being forced into the cylinder during the air intake phase of the four stroke cycle.
Turbocharged engines are used extensively in a number of applications. Some of which are electrical power supply, train, auto and the maritime industry. Also, because of its versatility they are widely installed on heavy duty machinery and in remote locations such as within the mining industries.
The four strokes of the cycle are induction, compression, power and exhaust. The turbocharger is driven by waste gas exiting the engine. Volumetric efficiency is achieved when the intake air is compressed by the turbocharger. This forces a greater volume of air into the cylinder during the induction stroke.
Before the exhaust gas is emitted into the atmosphere it flows through the turbocharger turbine casing that is attached to the exhaust manifold. The turbine and compressor are housed separately but are connected to the same freely rotating shaft. This allows for the exhaust gas to drive the turbine, resulting in the air being compressed.
The compressor housing is connected to the intake air manifold. Upon commencement of the induction stroke the compressed air is forced into the cylinder. Unlike an engine that is aspirated naturally which depend solely on the pistons' downward movement for its supply of air.
The containment of vibration and piston slap is said to immensely reduce the loudness of the turbo diesel engine. Recycled exhaust gas is said to help in the reduction of emission. These engine releases more exhaust gases into the atmosphere. However, it is widely believed that the carbon dioxide released by these engines is much less than those that use gasoline.
