摘　　要：在一台小型高速单缸压燃式发动机上,利用商用辐射传感器测量了缸内辐射传热量。实验包括在变转速和变负荷情况下,缸内缸盖火力面辐射热流量的测量。研究表明,在不同的运转工况下,发动机缸内的辐射热量是变化的。负荷增加时辐射热量增加,转速增加时辐射热量减少。The heat radiation in cylinder of a high speed light load compression ignition engine is measured using a heat radiation sensor. Experiment include varying the load and speed of engine. Results show that the heat radiation level in cylinder is variable under different operation condition. There is a increase in heat radiation with a increase in load, and there is a decrease with an increase in speed.
