Curtiss L
The Curtiss L is the first in a series of water-cooled V8 engines, produced by the Curtiss Aeroplane and Motor Company.
Early Curtiss engines were air-cooled, but in pursuit of greater power, Curtiss began developing liquid-cooled designs. Historical records indicate a Model L engine was fitted to a Curtiss built monoplane which was displayed, but not flown, at the 1910 Gordon Bennett race at Belmont Park, New York. It is also likely that a Model L engine powered the aircraft that crashed in Macon, Georgia, in 1912, resulting in the death of the aviator Eugene Burton Ely.
Continued development of Curtiss's V8 series eventual lead to the commercially successful Curtiss OX-5 engines which were built in large numbers during World War I.
