"The modern Diesel engine is a hybrid incorporating the features of direct (airless) injection patented by Akroyd-Stuart in 1890 and compression ignition, patented by Rudolf Diesel in 1892. Akroyd-Stuart's compression ignition engine was invented two years earlier than Diesel's similar engine."
http://en.wikipedia.org/wiki/Herbert_Akroyd_Stuart My bubble is being burst...Diesel did not invent the diesel engine? Akroyd-Stuart patented direct (actually it was indirect) injection b4 Diesel. Diesel patented compression ignition b4 Akroyd...BUT Akroyd Stuart had a working oil injection (no air-fuel mixture)/compression ignition engine 2 YEARS BEFORE DIESEL. Now, Akroyd's engine had a pre-chamber with a hot plate (took 5-10 minutes to warm up)...oil was injected onto the hot plate and vaporized (simply a way to atomize?) and then was combusted in the power stroke following the compression stroke. This IS different than indirect injection, specifically the hot plate, but if we define a diesel engine as a direct/indirect injection compression ignitition engine, then Diesel was not the first to invent or build one!
