The Ford Model T
used a 177-cubic-inch inline 4-cylinder engine
. It was primarily a petrol engine
, but it had multifuel
ability and could also burn kerosene
. It produced for a top speed of . The engine had side valves
and 3 main bearings
and was built in-unit with the Model T's novel transmission
(a planetary design
), sharing the same lubricating oil
. The engine bore was and its stroke was even, for a total displacement
of . Casting all four cylinders in one block
was an uncommon practice when T production started in 1908.
The spark plugs
were powered by a magneto
(as typical of the time), and the ignition system
included a manual advance/retard control. Starting was via a hand crank.
The Model T engine was produced continuously from September 27, 1908 through August 4, 1941, exactly 12,000 days. This makes it one of the longest engines in series production, especially considering that the specifications remained mostly unchanged for this entire duration. Its production run for the U.S. consumer market for passenger cars and pickups was shorter, being the 19 years' production run of the Model T itself for that market (1908 to 1927). But the engine continued to be produced and sold to various consumer, industrial, military, and marine markets throughout the world until 1941.
The following major changes were made (listed by year):
- 1909 — Water pump was discontinued; subsequent Model T engines used thermosyphoning to circulate the coolant.
