The outcome shows that such digital electronic speed governor is in possession of stable timing rate of 1 . 0 % and instantaneous timing rate of 6 . 2 % . and it is worth a wide popularization for its simple structure and low cost 在对hondagx31汽油机进行了大量试验后结果表明：在标定转速6000r min时，该电子调速器可以达到1 . 0的稳态调速率和6 . 2的瞬态调整率，优于国家标准的要求。
