First MWM Diesel Engine Equipped with Turbocharger

In 1905, Alfred Büchi, the founder of the exhaust gas turbocharging technology, obtained the patent for the turbocharger. His invention was based on the discovery that at the time, about a third of the energy generated by combustion engines was lost with the exhaust gas. Büchi came up with the idea of using the exhaust energy for propelling a turbine. The turbine, in turn, powered a compressor (supercharger) that precompressed the intake air in the suction pipes. Using this method, he was able to boost the performance of combustion engines by more than 40 percent in 1925. Once this invention became known and more and more engine manufacturers started using the technology for their combustion engines, MWM also started equipping and selling its diesel engines with turbochargers starting from the late 1930s.
