Title:Low-Temperature Cranking Load Requirements of An Engine-Air Starter Method
Issuing Committee:Electrical Systems Group
Scope:The air cranking system components, which include the tank, valve, hose, and starter, 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 inital selection of these components, needs to consider low-temperature engine torque requirements. To insure an adequate air cranking system is obtained, it is important that prooper test procedures are used for obtaining the cranking load requirements of the engine.Product Code:SAE AS90708
