Otto (Nikolaus Otto)

Nikolaus Otto was an engineer who developed the first practical internal combustion engine that ran smoothly by compressing a mixture of air and fuel before ignition, a process called the Otto cycle. This engine used a piston inside a cylinder to convert fuel into mechanical energy, powering early automobiles and machinery. His invention was fundamental in advancing engine technology, making it more efficient and reliable, and laid the groundwork for modern gasoline engines used today.
