The fuel-saving control system comprises a brake sensing controller, a downhill sensing controller and a fuel cut-off actuator, the brake sensing controller and the downhill sensing controller are connected with an OR gate actuator through lines, and the fuel cut-off actuator is connected with the brake sensing controller and the downhill sensing controller through lines. And the fuel cut-off actuator synchronously recovers normal oil supply of the oil way when the accelerator pedal is stepped down. The brake sensing controller is connected with the brake pedal through a circuit; when an automobile brakes during running, the brake pedal is stepped down, the accelerator pedal is kept in a lifting state, the brake sensing controller sends a fuel cut-off signal to the fuel cut-off actuator at the moment, and the fuel cut-off actuator cuts off an oil way immediately to stop oil supply; when braking is finished, the brake pedal is lifted, at the moment, the brake sensing controller sends an oil supply signal to the oil cut-off actuator, and the oil cut-off actuator immediately recovers normal oil supply of the oil way. The downhill sensing controller is installed in an air inlet pipe of the engine, and a downhill idling airflow threshold value is preset.
本发明公开了一种汽车发动机节油控制系统:包括刹车感应控制器、下坡感应控制器以及断油执行器,刹车感应控制器与下坡感应控制器通过线路与或门执行器连接,断油执行器通过线路分别与刹车感应控制器以及下坡感应控制器连接,断油执行器在油门踏板踩下时同步恢复油路正常供油。刹车感应控制器通过线路与制动踏板连接;当汽车行驶中刹车时,踩下制动踏板,油门踏板保持抬起状态,此时刹车感应控制器向断油执行器发出断油信号,断油执行器立即切断油路停止供油;制动结束,抬起制动踏板,此时刹车感应控制器向断油执行器发出供油信号,断油执行器立即恢复油路正常供油。下坡感应控制器安装在发动机进气管内且预设有下坡怠速气流阈值。
