What engineer Nikolaus August Otto developed?
Engineer Nikolaus August Otto developed the first four-stroke internal combustion engine and established the Otto cycle, a well-known theoretical cycle that governs the operation of explosive engines.
Otto's engine outperformed the steam engine in use at the time in a number of ways. One of them is their light weight, as steam engines need large water reservoirs and fuel to burn in order to heat the water, which in this case would be charcoal or firewood. In addition to being light, the internal combustion engine consumed little fuel, even benzene. Another factor was Otto cycle internal combustion engines' power, which also outperformed steam engines in terms of size ratio.
These benefits put pressure on the automotive sector to build vehicles with this kind of technology. Blacksmiths were compelled to learn new skills in order to use this new technology.
In addition to being light, the internal combustion engine consumed little fuel, even benzene. Another reason was Otto cycle internal combustion engines' power, which also outperformed steam engines in terms of size ratio.
