| 摘 要： | 测量各种发动机辅助制动器工作时不同发动机转速和机油温度下的气缸压力,分析了各种因素对制动功率的影响。结果表明:随着发动机转速的升高,最大缸内压力增大;制动功率随转速的升高而增大,减压制动功率最大,发动机倒拖制动功率最小;当发动机转速一定时,发动机的制动功率随机油温度的降低而增加,但过低或过高的机油温度都会影响发动机的工作性能。

| Abstract: | The cylinder pressures for different engine braking devices were measured at different speeds and oil temperatures and the influencing factors of braking power were analyzed.The results show that,with the increase of engine speed,the maximum in-cylinder pressure increases and the braking power also increases.During the course,the decompression braking power reaches the biggest and the dragging braking power reaches the smallest.At a certain speed,the engine braking power reduces with the increase of oil tem... |
