The turbocharger was invented by Swiss engineer Alfred Buechi. His patent for a turbocharger was applied for use in 1905. Diesel ships and locomotives with turbochargers began appearing in the 1920s. A turbocharger, or turbo, is an air compressor used for forced-induction of an internal combustion engine. Like a supercharger, the purpose of a turbocharger is to increase the mass of air entering the engine to create more power. However, a turbocharger differs in that the compressor is powered by a gas turbine driven by the engine's own exhaust gases.

The post world war II economic development spawned the rise of several turbocharger design and development companies that would specialize in turbochargers. These companies like Schwitzer, Garrett, Holset and others design and manufacture turbochargers for the world's leading engine manufacturers. But each of these original equipment turbo manufacturers also make their products available through their own distribution network to provide end-user customers with genuine quality engineered product through companies that specialize in these disciplines. In some cases these experts will even have updated product with features that exceed the original equipment in durability or performance; that's their job, bringing the latest technology to you, the customer.
