摘　　要：对利用微机控制的高速直喷式柴油机的怠速稳定性进行了试验研究。结果表明,n—Q 特性和燃料喷射系的过渡特性对发动机的怠速稳定性都有较大影响。数控电子调速器可改善高速直喷柴油机的怠速特性。Experiment and research on the idle stability of the high-speed direct injec- tion diesel engine controlled by a micro processor show that n-Q characteristic and the transition characteristic of the fuel injection system have greater in- fluences on the idle speed stability.Digital control electronic governor can im- prove the idle speed characteristic of the high-speed direct injection diesel en- gine.
