Turbochargers for the 1980s-Current Trends and Future Prospects

Due to the combined effects of economic pressure, fuel consumption and emissions goals, turbochargers are now used on gasoline and diesel engines covering the power range from around 100 to 50,000 hp.

The requirements placed on turbocharging systems in the very different applications of automobiles (gasoline and diesel), trucks and off-highway vehicles are reviewed. The developments that will be required in the 1980's are highlighted, together with an analysis of current limitations and future potential. These developments relate not just to turbo-machinery, but to matching, system design and maximizing exhaust gas energy utilization.
