(1)为便于起动发动机,对电起动系统应加强保养,以使预热装置作用良好,根据气温下降情况适当增大蓄电池电解液的比重,注意保温和对蓄电池进行必要的补充充电。起动时发动机应用热水预热,并应加热油底壳和变速箱的润滑油。(2)为了防止发动机冷却温度过低,散热器前应增设保温被。 (1) In order to start the engine, the electric starter system should be strengthened and maintained so as to make the preheating device function well. Appropriately increase the specific gravity of the battery electrolyte according to the temperature drop, keep warm and recharge the battery as necessary. The engine shall be preheated with hot water at start-up and the oil in the oil pan and gearbox shall be heated. (2) In order to prevent the engine cooling temperature is too low, the radiator should be added insulation.
