The turbocharger can either be a factory-fitted or an add-on component in a vehicle. Turbos which were originally considered as a part for racing cars have gradually made their way into mainstream vehicles as well, owing to the increasing needs of car owners. Turbochargers are enhanced versions of superchargers.




The turbocharger is used to push compressed air into the engine, allowing it to burn more fuel, thereby increasing the power generated by the engine. The main components of a turbo include: a turbine, compressor, central shaft, and the center housing and hub rotating assembly (CHRA). The turbocharger is powered by the exhaust gases. When the exhaust gases enter the turbo, the turbine which is connected to the compressor via a common central shaft, rotates. This in turn, rotates the compressor which sends the compressed air to the intake manifold.


How Turbo Works    


Sometimes, all exhaust gases do not need to necessarily enter the turbo, as it may result in an increased intake pressure. A waste gate is included in the turbo to release the excess exhaust gases and keep the intake pressure at the optimal level. Often, an intercooler is included between the turbo and the engine's intake system to cool the compressed air from the turbo before it enters the engine. This serves two purposes: It protects the manifold from excessive heat; and by reducing the temperature of the intake air, it provides a better combustion and improved efficiency.


Turbocharger Installation Overview    


Since the turbochargers depend on the exhaust gases to operate, a lag occurs between the gas pedal input and turbo action. The lag directly depends on the size of the turbocharger: the larger the size of the turbo, the more the lag. Common symptoms of a bad turbocharger include decreased engine efficiency and slower acceleration. The lighting up of the “Check Engine” signal on your dashboard and a blue-colored exhaust smoke are some visible symptoms of a defective turbo.
