Cover Story Supercharging

Rolls-Royce Power Systems and G+L innotec have jointly developed a new technology for electrically-assisted charging of off-highway engines. In the following, the advantages of the concept in comparison to conventional turbocharging systems as well as development and design considerations together with test results are presented.

New Requirements

The transient response capabilities of turbocharged diesel engines have been the focus of particular attention for as long as such engines have been available. Turbocharging was introduced with the primary aim of increasing engine efficiency and power density. However, due to the technical design any possible power uptake at the engine always involves a delay. In the off-highway sector, the greatest requirement for rapid torque development mainly occurs in drive plants for heavy trucks, trains and yachts. However, a growing demand for fast power delivery is increasingly apparent in the field of genset engines, primarily for emergency power...
