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.
The mining, maritime and auto industries are some of the entities that utilize the use of turbocharged engine. They are also widely used on trains, electrical power generation and on heavy duty machinery's. They are considered to be efficient, reliable and versatile.
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.
The turbocharger consists of a turbine and a compressor, both in separate housing. However, both are connected to the same shaft which rotates freely. The turbine side is connected to the exhaust manifold, while the compressor side is connected to the intake air manifold. The exhaust gas upon exiting the cylinder flows through the turbine housing and in so doing drives the turbines.
An engine that is naturally aspirated gets a fresh charge of air whenever the piston moves downward during the induction stroke. However, with an engine that is turbocharged intake air is compressed by the compressor. This allows for a large volume of air to be admitted into the cylinder during the induction stroke. The compressor is driven by the turbine.
Exhaust emission is said to be reduced with the recycling of exhaust gases. More exhaust gas is release into the atmosphere by the turbo diesel engine. However, it is believed that gasoline engine releases more carbon dioxide. The noise created by vibration and also piston slap is contained hence a much quieter engine.
