Turbocharging diesel engines is nothing new. The most basic premise of a diesel engine is the more fuel and air you mix during compression, the more power you get.
- Wastegate Turbocharger
- Fixed Vane Turbocharger
- VVT/VGT Turbocharger
- Compound Turbocharger
- Twin Turbocharger

Between 1885 and 1916 a few patent applications were submitted for products that address the general concept of turbocharging, but it was in 1925 that Swiss Engineer Alfred Buchi put the first commercially available turbo on a 10 cylinder diesel engine. Turbochargers use exhaust gas pressure to drive a Turbine Wheel that is connected to a Compressor Wheel. The compressor wheel forces cold air into your engine. You're using exhaust pressure to create boost pressure.
