Chevrolet Automobile Promo Film 'E for Efficiency' 88564 (1950)

Synopsis

Chevrolet’s 1950 short film, “E for Efficiency,” produced by Jam Handy, touts the efficiency of Chevrolet’s valve-in-head engine. This type of engine ( 02:12 ) is only found in Chevrolets when it comes to sedans, such as the 1949 or 1950 Chevrolet Styleline ( 00:51 ). The film begins with an animation to briefly explain the general idea of efficiency. Continuing with animation, the film looks at a simplified model of the valve-in-head engine and how it maximizes power and fuel economy, piston strokes, and heat loss. It compares the efficiency of the valve-in-head model to the L-head type. Part of the success of Chevrolet’s engine is making the pistons and cylinder block from the same cast alloy ( 06:18 ). The film shows how Chevrolet’s valve-in-head engine has perfected engine lubrication ( 06:58 ) by lubricating cylinder walls and bearings. Chevrolet isn’t the only company to utilize the valve-in-head type: some of the fastest race cars ( 08:02 ) in the world use it, as well as airliners, like Eastern Air Lines and what appears to be its Douglas DC-4 jet ( 08:09 ). The film concludes by showing several Chevrolet models with the valve-in-head engines, including what appears to be a 1949 Chevrolet Fleetline Deluxe ( 08:34 ) and a 1950 Chevrolet Bel Air Convertible ( 08:40 ).
