The Ford Model T used a 177 cu in (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. The engine bore was 3¾ inches (95.2 mm) and its stroke was 4 inches even (101.6 mm) for a total displacement of 177 cubic inches (2896 cc). While all four cylinders cast in one block was uncommon at the time when production started in 1908, the detachable head was a totally new idea, soon copied by others due to easier maintenance.
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 productioncitation needed, especially considering that the specifications remained mostly unchanged for this entire duration. The following major changes were made: (model years)
- 1909 — Water pump was discontinued; subsequent Model T engines used thermosyphoning to circulate the coolant.
- 1911 — Valve covers were added
- 1917 — Higher head with larger water jacket
- 1919 — Engine starter introduced as an option
- 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 two additional bolts stiffening the transmission,
- 1927 — The carburetor throttle rod was re-routed over the engine
The Model T engine is on the Ward's 10 Best Engines of the 20th Century list.
