Exhaust-gas turbochargers by MAHLE

The exhaust-gas turbocharger: a growing business segment …
Exhaust-gas turbochargers are a key technology to enhance performance, reduce fuel consumption, and lower exhaust emissions. When fitted to direct-injection diesel engines, they reduce fuel consumption by up to 25 percent compared with similar gasoline engine with duct injection. For this reason, they have taken over almost the entire market segment. The trend with gasoline engines is toward downsizing, that is to say, a reduction in cubic capacity for the same power output. This is achievable by turbocharging, since the high power-to-capacity ratio of these engines requires an increase in the air mass supplied to the engine. This is only attainable by supercharging. Inevitably, the number of turbocharged gasoline engines will undergo a significant rise worldwide.

Experts estimate that in 10 years time, there will be about 160 million cars and roughly 16 million trucks (>3.5 metric tons) running on this key technology, and the tendency will continue to rise. As a result, the turbocharger segment represents one of the largest growth markets in the automotive industry worldwide.
