发动机有效功率的检测方法有两种,即稳态测功法和动态测功法。稳态测功法是指用测功器对发动机进行加载,在节气门开度一定和其它参数保持不变的稳定状态下,测定发动机功率;动态测功法是指在发动机节气门开度和转速均变化的状态下,测定发动机功率,由于测功时不对发动机加载,故又 There are two ways to detect the effective power of the engine, that is, steady state dynamometry and dynamic dynamometry. Steady-state dynamometry refers to the use of dynamometer to load the engine, the throttle opening must be constant and other parameters remain unchanged under the steady state, the determination of engine power; dynamic dynamometry refers to the engine throttle opening and Under the condition that the speed is changed, the engine power is measured. Since the engine is not loaded when the power is measured,
