An internal combustion engine was a heat engine in which combustion occurred at high temperatures and/or pressures.
Automobiles in the 20th and 21st centuries were powered by these engines, which were fueled by gasoline. A side-effect of the use of these engines was the production of smog. (ENT: "Carpenter Street"; TOS: "Bread and Circuses"; VOY: "The 37's")
