oilcon = The Ford Model T used a 177 in³ (2.9 l) 4 cylinder engine producing 20 hp (15 kW) for a top speed of 45 mph (72 km/h). The engine had side valves and 3 main bearings and was built in-unit with the Model T's novel transmission, sharing the same lubricating oil. Engine bore was 3¾ inches (95.2 mm) and stroke was 4 inches even (101.6 mm) for a total displacement of 2.9 l (2896 cc/177 in³).

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 productionFact|date=February 2007, especially considering that the specifications remained mostly unchanged for this entire duration. The following changes were made over the years:
* 1909 — Water pump was discontinued; subsequent Model T engines used thermosyphoning to circulate the coolant.
* 1910 — Valve covers were added
* 1917 — Higher heads with larger water jacket
* 1919 — Engine starter introduced
* 1920 — Lighter-weight rods and pistons
* 1922 — The cylinder casting was changed so a single valve cover could be used
* 1926 — An extra boss was added at the rear for an additional transmission bolt
* 1927 — The carburettor throttle rod was re-routed over the engine

The Model T engine was on the Ward's 10 Best Engines of the 20th Century list.
