The invention relates to a low-temperature cold start control method for a plateau range extender, and discloses an engine internal air pressure and an engine temperature, an engine ignition target concentration is obtained according to the engine internal air pressure, and the target concentration and an injection mode control command are sent to a combustion-supporting device controller; the combustion-supporting device controller controls the combustion-supporting device to enter a combustion-supporting mode and controls the combustion-supporting device to inject combustion-supporting gas according to the target concentration; and obtaining a target rotating speed for starting the range extender according to the engine temperature, sending the target rotating speed and the rotating speed mode control instruction to a generator controller, enabling a generator to enter a rotating speed mode under the control instruction of the generator controller, and controlling the generator to rotate according to the target rotating speed. The problem that the engine is difficult to start under the conditions of overspeed at low temperature and high pressure is solved.
本发明涉及一种高原增程器低温冷启动控制方法,且公开了获取发动机内部气压和发动机温度,根据发动机内部气压得到发动机点燃的目标浓度,将目标浓度和注射模式控制命令发送至助燃器控制器,以使助燃器控制器控制助燃器进入助燃模式,并根据目标浓度控制助燃器注射助燃气体;根据发动机温度得到增程器启动的目标转速,将目标转速和转速模式控制指令发送至发电机控制器,使得发电机因为发电机控制器控制指令下进入转速模式,并且控制发电机按照目标转速转动。解决发动机低温情况下超转速和高压情况下发动机难以启动的问题。
