1.低温启动难的原因(1)启动转矩减小。给启动电机提供电力的蓄电池电能越足,则启动转矩越大,启动柴油机越容易,反之则不易。低温环境下,启动转矩减小。低温时,蓄电池内的电解液黏度增大,极板收缩,极板上的活性物质难以参加化学反应,使放电过程缓慢,蓄电池的电容量下降。同 1. Low temperature start difficult reasons (1) start torque reduction. The more battery power to provide power to the starter motor, the greater the starting torque, the easier it is to start the diesel engine and vice versa. Low temperature environment, the starting torque decreases. Low temperature, the battery electrolyte viscosity increases, the plate contraction, the active material on the plate is difficult to participate in chemical reactions, the discharge process is slow, the battery capacity decreased. with
