Nikolaus Otto

Nikolaus Otto was an engineer who invented the four-stroke internal combustion engine in the late 1800s, a breakthrough that greatly influenced modern automobiles. His engine operates through four steps—intake, compression, power, and exhaust—inside a cylinder, which converts fuel into mechanical energy to move vehicles. This design is more efficient and reliable than earlier engines, making engines more practical for everyday use. Otto’s innovation laid the foundation for automotive technology and contributed significantly to transportation development worldwide.
