Engine Cranking at Arctic Temperatures 550272

A NEW arctic engine oil, designed to permit cold-weather operation of Army equipment, has been tested to determine required cranking effort. Data obtained are to be used to design new cranking equipment and to estimate the temperature limits of existing cranking equipment.
Tests were conducted on six gasoline engines and five diesel engines using the new oil conforming to MIL-O-10295. Cranking the engines through a torquemeter permitted direct measurement of cranking torque.
The results of the investigation are presented in this paper.
