What is the compression of a Model T Ford engine?
The compression ratio of a Model T Ford engine was approximately 4.5:1. This low compression ratio was a key design feature of the Model T, which was intended to be a simple and affordable car for the masses.
Understanding the Compression Ratio of the Model T Ford Engine
The compression ratio of an engine refers to the ratio of the volume of the cylinder when the piston is at the bottom of its stroke (the largest volume) to the volume when the piston is at the top of its stroke (the smallest volume). This ratio is a critical factor in determining an engine's power output and efficiency.
The Model T Ford, introduced in 1908, was designed by Henry Ford to be a practical and affordable car for the average American consumer. To achieve this, Ford opted for a relatively simple and low-cost engine design, which included a compression ratio of just 4.5:1.
Reasons for the Low Compression Ratio
There were several key reasons why the Model T Ford engine had such a low compression ratio:
- Fuel Quality: In the early 20th century, the quality of gasoline available was relatively poor, with a high tendency for knocking and pre-ignition at higher compression ratios. The low 4.5:1 compression ratio of the Model T engine helped to prevent these issues.
- Simplicity and Cost: A lower compression ratio allowed for a simpler, less expensive engine design, which aligned with Henry Ford's goal of making the Model T an affordable car for the masses.
- Durability: The low compression ratio also contributed to the Model T engine's reputation for reliability and durability, as it was less prone to mechanical issues and wear over time.
While the low compression ratio of the Model T engine limited its power output compared to later engine designs, it was a key factor in making the Model T an accessible and practical car for its time.

What should the compression be on a model Ford?
What would be considered a good compression for a stock model a engine. 60 and above. Within 10% across all bores is considered acceptable. Specs in the DeAngelis book calls for 76 psi.
How many miles per gallon did a 1923 Ford Model T get?
Based on data from 2 vehicles, 41 fuel-ups and 2,218 miles of driving, the 1923 Ford Model T gets a combined Avg MPG of 8.71 with a 0.79 MPG margin of error. Below you can see a distribution of the fuel-ups with 2 outliers (4.65%) removed.
What is acceptable engine compression?
“Good” compression depends on the engine. Unfortunately, engines don't come with their proper compression stamped on the outside. But a good rule of thumb says that each cylinder in a mechanically sound engine should have compression of 130 psi or higher.
What is the compression ratio of the Ford 292?
The 292 was available as the C-code engine option, once again with a slight difference between the manual transmission and "Fordomatic" automatic transmission. Compression was up to 9.1:1 in manual cars, which were rated 206 bhp (154 kW) at 4,500 rpm and 297 lb⋅ft (403 N⋅m) at 2,700 rpm.
What is the compression ratio of a Ford 302 engine?
The new 302 replaced the 289 early in the 1968 model year. The most common form of this engine used a two-barrel carburetor, initially with 9.5:1 compression.
