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。
The experiment of idling stability of high speed direct injection diesel engine controlled by microcomputer is carried out. The results show that the n-Q characteristics and the transition characteristics of the fuel injection system have a greater impact on the idle stability of the engine. NC electronic governor can improve the idle speed characteristics of high speed direct injection diesel engine.
