Patent of 1er stationary French diesel engine filed in 1901 by Pierre Clerget and Arthur Vernet (publication number GB190104220)
The particularity of this engine is to include a triple injector, making it possible to make “mixtures” of fuel, oxidizer and liquid catalysts and in particular water with more or less heavy oil which has the effect of largely promoting combustion. .
P. Clerget was a genius engine engineer. He later turned to nascent aviation and developed efficient gasoline engines there. It will even make some diesel aviation engines during the 1930s (Clerget 9A, 9B, 14D…). What was, and still remains (given the rarity of diesel engines in the air), a technological feat!
