The Ford Model T used a 177 cu in (2.9 L)
inline 4-cylinder engine. It was primarily a
gasoline engine. It produced 20 hp (14.9 kW)
for a top speed of 45 mph (72 km/h)

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). The engine
was capable of running on gasoline, kerosene, or ethanol

Fuel system Gravity feed
Holley, Kingston and Zenith carburettors
one carburetor, a side-draft, single-venturi unit

The compression ratio was 3.98

The low compression of the Model T means that the combustion
is not hot enough to form nitrogen oxides, the NOX, that forms smog.

The amount of carbon monoxide, CO, and unburnt carbon that the T
puts out depends on how well the T is running and how the carburator
and spark are adjusted.

Has anyone taken a T to a smog station to have it tested?

Believe it or not, in NJ a Model T is required to pass an emissions
inspection if it is not registered as "Historic." All pre-1968 vehicles
have to meet the same standard (1400ppm-HC, 8.5%-CO).

Does it smell like petrol in here ?

Here's the emissions report from an emissions check on a Model T.
Subject to someone setting the manual controls properly
for the test of course.

HC ppm 253 1400 ppm
CO% 5.69 8.5%
CO2% 5.7
O2% 10.3

On another car

NOX 5PPM
