摘　　要：在无外载测功原理基础上，设计了内燃机瞬时转速的测量装置，经小型单缸柴油机加速过程瞬时转速的测量与分析，确立了加速度谱与相应加速时间间隔的函数关系。采用平均加速扭矩法测量加速功率，可明显改善小型柴油机无外载测功精度。Measuring facilities for the instantaneuous rotation speed of internal combustion engine have been developed on the base of non-extra-load power measuring principle. By measuring and analysing of a single-cylinder diesel engine the function of the acceleration speed spectrum and conresponding acceleration time gap is deduced. The measuring results at non-extra-load is more precise by using average accelerative torque range method to measure the accelerative power
