Where did turbocharging come from?

Turbocharging originated in the early 1900s, with its first patent filed by Swiss engineer Alfred Büchi in 1905. The technology was initially developed to improve the efficiency and power output of internal combustion engines, particularly in aviation and later in automotive applications. Over the decades, it gained popularity in racing and commercial vehicles, significantly enhancing engine performance while maintaining fuel efficiency. Today, turbocharging is widely used in various vehicles to meet power and emissions requirements.
