Wilson, D E

Continued emphasis has been placed on reducing the specific fuel consumption (sfc) of heavy-duty diesel engines. Through design improvements, engines with sfc levels of 200 g/kW-hr are now reaching the consumer. With the addition of turbocompounding, sfc can be reduced below 185 g/kW-hr. This paper describes the concept, design, and initial performance test of an 11.3 liter, 6 cylinder non-insulated turbocompound engine. Improvements in the turbocharged engine design resulted in a rated sfc of 192 g/kW-hr. The turbocompound engine demonstrated an sfc of 182 g/kW-hr at the same rating.
