Informative Paper Internal Combustion Engine Many people claimed the invention of the internal combustion engine in the 1860's, but only one has the patent on the four stroke operating sequence. In 1867, Nikolaus August Otto, a German engineer, developed the four-stroke "Otto" cycle, which is widely used in transportation even today. Otto developed the four-stroke internal combustion engine when he was 34 years old. (Internal Combustion Engine) The Diesel Engine came about in 1892 by another German engineer, …

…end of the compression stroke. In Diesel engines, compression ratios are as high as 22.5 to 1 and provide pressures of 500psi at the end of the compression stroke. Through the compression process, the air can be heated up to 1000 degrees F. This temperature is high enough to spontaneously ignite the fuel as it is injected into the cylinder. The high pressure of the explosion forces the piston down as in the gasoline engine. (Internal Combustion Engine)
