In theory, turbocharged engines have advantages in obtaining similar power performance or lower fuel consumption.
In theory, turbocharged engines have advantages in obtaining similar power performance or lower fuel consumption.
The principle of a turbocharged engine is to force the engine to suck in air, so that under the same cylinder volume more air will enter, more mixture will burn and expand in a relatively small space, producing more power than a self-priming engine, and fuel consumption is lower than that of a self-priming engine of the same power level. Small-displacement turbocharged engines are the trend. In addition to lower fuel consumption than self-priming engines of the same power level, displacement tax, vehicle and vessel tax, and exhaust emission standards are lower than self-priming engines. Therefore, automakers will widely use turbocharged engines instead of self-priming engines.
