Designed for those who maintained ship and submarine power plants, this WWII era black & white training film is about the lubrication system. Copyright 1943. The Detroit Diesel Series 71 is a two-stroke diesel engine series, available in both inline and V configurations. The inline six-cylinder 71 series engine was introduced as the initial flagship product of the Detroit Diesel Engine Division of General Motors in 1938. The first number in the model series designation refers to the number of cylinders, and the second - 71 - the nominal displacement per cylinder in cubic inches, a rounding off of 70.93 cu in (1.2 L). Inline models included one, two, three, four and six cylinders, and the V-types six, eight, 12, 16 and 24 cylinders.
The two largest V units used multiple cylinder heads per bank to keep the head size and weight to manageable proportions, the V-16 using four heads from the four-cylinder inline model and the V-24 using four heads from the inline six-cylinder model. This feature also assisted in keeping down the overall cost of these large engines by maintaining parts commonality with the smaller models.
