Testing of a Low Specific Fuel Consumption Turbocompound Engine 870300

Refinements to reduce the operating costs of heavy-duty diesel engines have resulted in new production engines with specific fuel consumption (sfc) below 200 g/kW-hr. Turbocompounding the heavy-duty diesel engine results in further reductions in sfc. This paper describes a research program for testing of an 11.3 liter, 6 cylinder turbocompound diesel engine which has demonstrated a significant reduction in specific fuel consumption, down to 180 g/kW-hr, as well as improved transient emissions and response.
