Current and Advanced Design Concepts for High Power-Density Mid-Range Truck Diesel Engines Part I: Technology Review

This paper follows an earlier one (Ref. 1) in reviewing the present technological status of Mid-Range Truck 300/400 Series diesel engines, with emphasis on new engines and concepts presented after 1994. The elements that affect the combustion process (valve train, combustion, fuel and air-charging systems) are discussed. New head designs are proposed, including some with radial valves. Part II discusses the tools used in modern engine analysis.
