Application of Air-To-Air Charge Cooling to the Two-Stroke Cycle Diesel Engine

The combustion and air system development of the air-to-air charge cooled two-stroke cycle diesel engine for the heavy-duty truck market is described. The conceptual modifications to the actual turbocharged-charge cooled diesel cycle are defined and supported by analytical modeling results and engine dynamometer development test results. Actual engine and vehicle performance are provided to demonstrate the significant achievement in fuel efficiency made via the optimizing scheme employed.
