Abstract
Engine starting torque requirement at extreme cold and hot conditions is not possible to evaluate by transient dynamometer. Due to this, starting system design may not meet the engine starting requirements under all operating environments.
Starter motor can be used to overcome this problem.
This paper deals with how to evaluate engine starting torque at all temperatures through starter motor.
Conventionally, engine cold startability and hot startability are evaluated by using a starter motor of bigger rating. A new methodology found to circumvent this issue and it is, by evaluating the strain experienced by the pinion and drive mechanism, engine starting torque demand can be evaluated at any temperature.
By this process, starting system design can be made to suit the correct requirements of the engine starting.
