Air cooled, much like the old "hit and miss" farm engines.
Almost all of the first aircraft engines were air cooled as this made for a lighter engine.
1982 is the first liquid cooled 80
The tractor, these were known as traction engines as they were steam powered tractors based on steam engines for trains.
The engines made for the Ford were made by the Dodge brothers before they decided to start their own automobile company in 1914.
The first Subaru automobile was produced in 1954. The model number was the 1500. The next model was the small air cooled 360 in 1958.
When air is cooled, the gas that typically condenses first to form a liquid is water vapor. This process occurs at a specific temperature known as the dew point, where the air becomes saturated with moisture and water vapor condenses into liquid water droplets.
Some used steam-powered engines, others used early petrol or gas engines. Some even used battery-powered electric motors.
the first airplanes used engines very similar to ones found in automobiles, later aircraft often featured air cooled rotary engines for their light weight before being replaced by jet engines.
Gasoline was first used as a fuel for internal combustion engines in the late 19th century, with the invention of the first gasoline-powered automobile by Karl Benz in 1885.
Depends of which rocket you are talking about. Fire arrows used gun powder, but they were made to explode. Goddars rocket used liquid oxygen and gasoline. The Saturn V F1 engines used Liquid oxygen and kerosene while the J2 engines used liquid oxygen and liquid hydrogen.
The first Automobile was built in USA. Henry Ford built the first automobile.
Most basic difference: The automobile engine is overwhelmingly a gasoline engine. Rail engines were steam at first, and today are either diesel or electric. To my knowledge, there has never been a gasoline railroad locomotive.
