The Ford Model A engine – primarily developed for the popular Ford Model A automobile (1927–1931, 4.8 million built[1][2])[3][4] – was one of the most mass-produced automobile engines of the 1920s and 1930s, widely used in automobiles, trucks,[5] tractors,[6][7] and a wide variety of other vehicles and machinery.[8][6][9][10]
A four-cylinder, carbureted, gasoline-fueled, piston engine, derived from the Ford Model T engine, the Ford Model A engine – with a bigger bore and stroke, and higher compression ratio – was twice as powerful as the Model T engine.[3][11] Some derivatives, with improvements, were produced until 1958.[12] Tens of thousands of the original design remain active even in the 21st century.[13][3][14]
