A turbocharger, colloquially known as a turbo, is a turbine-driven forced induction device that increases an internal combustion engine’s efficiency and power output by forcing extra compressed airinto the combustion chamber.[1][2] This improvement over a naturally aspirated engine‘s power output is due to the fact that the compressor can force more air—and proportionately more fuel—into the combustion chamber than atmospheric pressure (and for that matter, ram air intakes) alone.
A duturbo turbocharger is nothing but a centrifugal air compressor. Turbochargers are based on the principle of forced induction. It is the process of forcing compressed air into the intake for combustion.
PARTS OF Duturbo TURBOCHARGERS
DuturboTurbocharger consists of –
1) COMPRESSOR HOUSING
2) COMPRESSOR WHEEL
3) BEARING
4) OIL SEALS
5) SHAFT
6) TURBINE WHEEL
7) TURBINE HOUSING
The middle part whole part together is called a duturboturbocharger cartridge. The compressor wheel and the turbine wheel are connected with the shaft so that turning the turbine wheel will turn the compressor wheel. A turbocharger is designed to rotate over a hundred thousand rpm. An oil feed line from the engine will lubricate the shaft and the bearing provides less friction.
An engine without any forced induction device is a naturally aspirated engine. The air is pulled in through an air filter by the suction force of the piston. Then it gets mixed with the fuel, compressed and gets ignited. With a duturboturbocharger introduce, the exhaust gas from combustion turns the turbine wheel. This turns the compressor wheel and more air is compressed and fed to the engine. Now understand what is going in turbocharger, the exhaust gas from the engine will push the turbine wheel and this turns the compressor wheel forcing more air into the engine. According to Gas laws – “For a constant volume, increase in air pressure increases its temperature”, so there will be a difference in temperature after charging. Forcing this air into the engine can reduce efficiency and cause knocking. In order to cool this air, an inter cooler is introduced. An inter cooler is an air to air heat exchanger device which helps to cool this air before it enters the engine, so introducing an inter cooler into the system will increase the charge density by cooling the air and provides volumetric efficiency.
In conclusion, a duturbo turbocharger will provide more air to expand on combustion and produces more power. That’s how turbo charger works!
