提出了一种采用ＭＣＳ－８０９８单片机控制的柴油机数字式电子调速器．通过单片机对柴油机转速进行数字ＰＩＤ调节，克服了传统机械式调速器的许多缺点．实验表明该调速器能够满足大多数中高速柴油机不同工况下的调速要求． A diesel digital electronic governor controlled by MCS-8098 is proposed. The single-chip diesel engine speed digital PID regulator to overcome many of the shortcomings of the traditional mechanical governor. Experiments show that the governor can meet the speed requirements of most medium-high speed diesel engines under different operating conditions.
