Rudolf Diesel invented the diesel engine.
He’s not actually in the fuel, mind you, except in spirit.
The German inventor developed the diesel engine back in 1890.
The diesel engine has the highest thermal efficiency of any regular internal or external combustion engine due to its very high compression ratio.
Manufactured in two stroke and four stroke versions, the largest diesel engine in the world is currently a Wartsila marine diesel of about 80 MW output.
Rudolf Diesel did not invent the diesel engine, the first true diesel engine designed, manufactured and a running example was that of of Herbert Akroyd Stuart, he had a running engine of his design and concept in 1886 which he later refined and put into production with Hornsby of England in 1891, Stuart was at least 3 years ahead of Rudolf Diesel.
