The Working Principle of Turbocharger
A turbocharger is mounted in the exhaust stream. On many of today's vehicles it is integrated into the exhaust manifold. Inside the turbocharger housing are two finned wheels -- think of the fan on a jet engine -- mounted on the ends of a common shaft. One of the wheels, the turbine, is powered by exhaust gases produced by the engine's cylinders. On the other side of the shaft is the compressor wheel. As the turbine spins the shaft, the compressor wheel turns at the same speed, drawing air into the turbocharger housing where it is compressed. The denser air is forced into the engine's cylinders. The tightly compressed mixture of air and fuel in the cylinders raises the output of the engine.
Turbocharger the biggest advantage is can not increase the engine emissions could more rapidly increase engine power and torque, in general, after install the supercharger engine power and torque increase 20% ~ 30% of the shortcoming of the turbocharger is lagging behind, namely, due to the effect of inertia of the impeller on the accelerator when sudden change is a slow response, make the engine delay increase or decrease the output power, and this for a car to sudden acceleration or overtaking, instantaneous can mention don't want to feel a bit.
