Turbochargers are both simple and effective. By supplying additional charge air to the engine, they improve fuel combustion, increase engine output, help to optimise fuel consumption and thereby reduce emissions.

MAN Diesel began designing and producing the first exhaust turbochargers in 1934. Since its invention by Swiss-born Alfred Büchi in 1905, not much has changed in terms of the technology’s basic principle – but its efficiency has. The earliest turbochargers boosted the output of engines by 40 percent. Nowadays, using cutting-edge MAN Diesel turbochargers increases output by around 300 percent. These power boosters are used for both two-stroke and four-stroke engines.
 
In 2001, MAN Diesel launched the new generation of axial turbochargers (TCA series), followed by the TCR series of radial turbochargers in 2004. The latest turbocharger technology from MAN Diesel sets new standards for exhaust gas reduction and low consumption. The Variable turbine area  (VTA) allows fuel consumption and the emissions associated with this to be minimised at partial load while at the same time tangibly improving the engine’s responsiveness to changes in load.
 
The developments of our turbocharger experts are essential in helping marine and power plant engines comply with ever stricter emissions requirements. Through their high-precision interplay with other components such as the injection system, efficient turbochargers therefore make an important contribution to environmental protection.
