发动机的低温启动负载要求 推荐做法

[中文适用范围]： 电动起动系统组件（包括电池、电缆和起动电机）必须经过仔细选择，以便在系统预期的最恶劣气候条件下提供启动发动机所需的速度。发动机起动负载随着低温而增加，因此，这些部件的初始选择需要考虑低温发动机扭矩要求。为了确保获得足够的电动起动系统，重要的是使用正确的测试程序来获得发动机的起动负载要求。 [外文原描述]： The electrical cranking system components, which include the battery, cables, and cranking motor, must be carefully selected to provide the necessary speed to start an engine under the most severe climatic conditions for which the system is intended. Engine cranking loads increase with cold temperatures, therefore, the initial selection of these components needs to consider low-temperature engine torque requirements. To insure an adequate electrical cranking system is obtained, it is important that proper test procedures are used for obtaining the cranking load requirements of the engine.Cross Reference: J300_201304,J300_201501,J544
