Detroit Diesel Series 71

Uncommon card · No. 104821

The Detroit Diesel Series 71 is a two-stroke diesel engine family that was available in both inline and V engine configurations, designed by General Motors and principally manufactured by Detroit Diesel (historically its subsidiary). The number 71 refers to the nominal displacement per cylinder in cubic inches, a rounding off of 70.93 cu in (1.2 L). The 6V-71 was commonly nicknamed “Screaming Jimmy” due to its distinctive high-pitched sound at its operating speed of 2,100 rpm. The engine’s characteristic noise could make it sound as though it were operating at nearly 4,200 rpm. Inline engines were produced with 1, 2, 3, 4 or 6 cylinders, and V engines with 6, 8, 12, 16 or 24 cylinders.
