Supercharger should refer to the engine intake supercharger, including three forms: exhaust gas turbocharger, mechanical turbocharger, electric auxiliary turbocharger. The supercharger compresses the air and increases the intake density of the engine, so that the liter power of the engine can be increased. At the same time, because the mixed combustion regulation of the engine has been improved, the combustion efficiency has been improved, and the effect of fuel saving and emission reduction can also be played. It is an important technical progress of modern engines. Now the common application is the engine exhaust gas turbocharger.
Advantages and disadvantages of various superchargers
Exhaust gas turbocharger is the use of exhaust gas from the engine to drive the turbine, thereby driving the coaxial air compressor to turbocharge the engine air, so its reaction is that the engine needs to increase the exhaust before it can get the corresponding power increase, so there will be a common "turbine lag" phenomenon, generally there will be a pause of about 2s, before it will get the power outbreak.
The mechanical supercharger uses the power of the engine to directly drive the turbine, compressed air into the engine, this way can directly obtain a stable speed, and there is no hysteresis, the power output is more smooth, but this way will lose the engine power, the supercharging efficiency is not very high.
The electric auxiliary supercharger improves the efficiency of the engine, the power output is stable, but the structure is complex, and the cost and maintenance cost are high.
