Experiments and simulations show that the proposed system can operate in audio switch frequency range without audio noise from the motor load, meanwhile, EMI can be limited to lowlevel.
实验与仿真结果表明:该系统采用音频开关而不导致电机负载的音频噪声,同时使EMI能被限制在低电平。

The ethanol engine has a whole lowlevel of soot while the only work is to decrease soot emission under full load conditions.
