While there were earlier attempts at internal combustion engines that used fuel injection, Diesel's design was the first practical and successful one. He achieved this by:
* Using compression ignition: He used the heat generated by compressing air to ignite fuel, instead of using a spark plug like in gasoline engines. This allowed for a more efficient engine that could run on cheaper fuels like kerosene and vegetable oils.
* Precise fuel injection: He developed a system for injecting the fuel into the combustion chamber at the right time and in the right amount, leading to smooth operation and high efficiency.
Although the first prototype of Diesel's engine didn't function as expected, he continued refining his design and eventually achieved success. His invention revolutionized transportation and power generation, and it remains a crucial technology in modern society.
