Ford Model A engines
« on: July 24, 2018, 01:35:19 AM »
This is only tangentally related to the Museum, so that's why I stick it here.

Our Model T railcar engine was built in 1931.  Someone emailed us asking how that could be when Ford stopped making Model A's in 1928.

Wikipedia tells me that Ford kept making T engines until 1941, but stopped making the car in 1928.  So why did they make the engines for more than a decade after they stopped building the car?

Ford made the model A with two different body styles, 1928-1929 and 1930-1931 but maybe they didn't call the later ones an A. The engine block was used for an optional 4 cylinder motor until 1941 however it was updated with a better full pressure oiling system and other improvements. In the 1932 Ford it was called the Model B and in later years it was reffered to as the Model C.

From Wikipedia

Main article: Ford Model T engine
Model T engine

The Model T had a front-mounted 177-cubic-inch (2.9 L) inline four-cylinder engine, producing 20 hp (15 kW), for a top speed of 40–45 mph (64–72 km/h).[23] According to Ford Motor Company, the Model T had fuel economy on the order of 13–21 mpg?US (16–25 mpg?imp; 18–11 L/100 km).[24] The engine was capable of running on gasoline, kerosene, or ethanol,[25][26] although the decreasing cost of gasoline and the later introduction of Prohibition made ethanol an impractical fuel for most users. The engines of the first 2,447 units were cooled with water pumps; the engines of unit 2,448 and onward, with a few exceptions prior to around unit 2,500, were cooled by thermosiphon action.[27]

The ignition system used in the Model T was an unusual one, with a low-voltage magneto incorporated in the flywheel, supplying alternating current to trembler coils to drive the spark plugs. This was closer to that used for stationary gas engines than the expensive high-voltage ignition magnetos that were used on some other cars. This ignition also made the Model T more flexible as to the quality or type of fuel it used. The system did not need a starting battery, since proper hand-cranking would generate enough current for starting. Electric lighting powered by the magneto was adopted in 1915, replacing acetylene and oil lamps, but electric starting was not offered until 1919.[28]

The Model T engine was produced for replacement needs, as well as stationary and marine applications until 1941, well after production of the Model T had ended. It was also utilized in the drivetrain of the Fordson tractor, which was produced in the US until 1928, and in Ireland until 1964.[citation needed]


Model T engines continued to be produced until August 4, 1941. Almost 170,000 were built after car production stopped, as replacement engines were required to service already produced vehicles. Racers and enthusiasts, forerunners of modern hot rodders, used the Model T's block to build popular and cheap racing engines, including Cragar, Navarro, and famously the Frontenacs ("Fronty Fords")[48] of the Chevrolet brothers, among many others.
