The first Fairbanks Morse fuel burning engine was sold in 1893.
The first gasoline engines with hot tube ignition were developed from a U.S. patent. Later designated as type "N" engines.
Type "N" engines were sold with ratings from 2-1/2 H.P. to 65 H.P. and burned natural gas as well as gasoline.
The largest early type "N" gasoline engine was rated at 65 H.P. but indicated 95 H.P. in use. It was installed in a large grain elevator in Camden, New Jersey.
