A Few Important Tips Concerning Turbo Diesel Engines

A four stroke cycle engine that is turbocharged is generally referred to as a turbo diesel. This type of engine as well as top quality turbo kits is extremely popular because of its increased volumetric efficiency resulting in a higher power output when compared to a naturally aspirated engine of similar size. The turbocharger two main components are the turbine and the compressor.

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.

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.

On the other hand, the compressor side of this unit is connected to the intake manifold and is driven by the turbine. This allows for the air to be compressed, which is then force into the cylinder as soon as the intake valves are opened. A naturally aspirated engine relies on the pistons’ downward action for a fresh charge of air.

According to dencodiesel, 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.
