Ford Model A engine
The Ford Model A engine – primarily developed for the popular Ford Model A automobile (1927–1931, 4.8 million built) – was one of the most mass-produced automobile engines of the 1920s and 1930s, widely used in automobiles, trucks, tractors, and a wide variety of other vehicles and machinery.
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. Some derivatives, with improvements, were produced until 1958. Tens of thousands of the original design remain active even in the 21st century.
The Ford Model A engine was an evolution of the Ford Model T engine, but with double the power. It was developed in secret at Ford's Rouge Plant, in Michigan, and unveiled – with the Ford Model A automobile – December 2, 1927. The first Model A engine was completed earlier, October 20, 1927, and eventually installed in a 1928 Model A Fordor sedan, which Henry Ford gave to his friend, inventor Thomas A. Edison. There was immediate market demand for the Model A, but by January 1, 1928, just 5,275 Model A engines had been built – some not yet installed in a chassis, let alone shipped to a dealer.
However, by February 1929, production of the engines reached 1,000,000 units. At the end of Model A production in March 1932, 4,849,340 Model As had been built. (Several hundred thousand Model AA trucks had also been built, typically with the same Model A engine.) Model A historian Steve Plucker, using Ford company records, calculates that 4,830,806 production engines were built between October 1927 and November 1931.
All Model A engines built in the U.S. were built in the Rouge plant, however some were built at Ford plants in Canada and Europe. During that time, the Model A and AA engine cylinder block (part number A-6010), went through various external and internal changes.
The Model A was replaced by the 1932 Ford Model B, with an updated 4-cylinder engine, and by the 1932 Ford Model 18, with its new Ford V8 engine.
Like the Model T engine, the Model A engine was a water-cooled L-head inline-four (four vertical cylinders in line), "cast-en-bloc"-type piston engine. It had a displacement of 200.5 cu in (3.3 L) (compared to the Model T's 177 cu in (2.9 L)).
This engine provides 40 hp (30 kW; 41 PS) (brake horsepower) at 2,200 RPM – but at 1,000 RPM produces substantially more torque: 128 lb⋅ft (174 N⋅m). SAE-rated horsepower is 24.03, and compression ratio is 4.22:1.
