摘　　要：对发动机泄漏缓速器在不同气门开度下的辅助制动能力进行了数值模拟计算及实验研究,结果表明,泄漏缓速器在不同发动机转速下有一对应的最佳气门开度,此气门开度大小随转速的升高而增大,通过调整气门开度大小,可以在同一转速下使发动机制动功率在一定范围内连续调整。The auxiliary braking capability of engine bleeding retarder is calculated and evaluated by numerical simulation and experimental test at different valve lift, the result shows that, there is an optimum valve lift to every steady speed in the bleeding retarder, this optimum valve lift goes increase with the engine speed, by adjusting the valve lift, we can get an continuously variable retarding power within an certain range at the same engine speed.

关 键 词：发动机制动 泄漏缓速器 功率调整
