For an engine of a given horsepower, single cylinder engines require large flywheels to keep the momentaryspeed variations.
对于一定马力的发动机来说，单气缸发动机需要较大的飞轮来保持其瞬时速度的变化。

The experimental results verified the accuracy and feasibility of the denoise method to process the momentaryspeed signal for engine misfire detection.
试验结果验证了该方法的可行性，为利用瞬时转速信号检测发动机失火提供了条件。

According to the basic characteristics of internal combustion engines, crank Angle domain and its frequency domain were chosen, and engine momentaryspeed fluctuations were divided.
