Install the turbocharger on the exhaust pipe, use the exhaust-gas from the cylinder of the engine to push the turbine blades, then to drive the blades of the compressor to send the air via the air filter into the cylinder with pressure. Because the air capacity entering the air cylinder are increased, more fuel oil are allowed to spray into the combustion chamber so as to make the fuel oil burning sufficiently, thus it makes the engine to generate more power or to reduce exhausting and oil consumption. The turbocharger also can make the engine obtaining power compensation when it is working on tableland.

The turbocharger with exhauster features low speed high torque, holding high or low speed performance. The operation of the exhauster is controlled by the intensified pressure from the turbocharger. When the intensified pressure is more than some predetermined value, the venting device is open and part of the exhaust-gas from the engine is vented directly, thus the rate of the intensified pressure is controlled and this makes explosion pressure in the cylinder not exceeding the allowable value of the mechanical loading of the engine.

Because the turbocharger is operating under the conditions of high-temperature and high-speed, when operating, the use and maintenance of it must be performed according to the proposal of the manufacturers of engine and turbocharger.
