"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."

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!

Thoughts?
