High Performance Regenerated Diesel Engines

The feasibility of a promising regenerated diesel engine concept has been under investigation for the past two years under a combined ReJen, Caterpillar and Navy effort. The most unique and novel feature of this concept is a movable regenerator. This approach, along with some newly developed materials and the Low Heat Rejection diesel technology that has been developed over the past ten years, offer the potential to attain the very high specific power and the improved fuel efficiency of a regenerated diesel engine. Under this proposed program, this investigation of the technical feasibility of this regenerated engine will continue. Aspects and features of the engine that have not yet been considered will be examined, including combus- tion and emissions performance and two stroke regenerated engine capabilities. These efforts will utilize the regenerated engine computer model developed under the current program as well as other analytical methods. As with the current program, Caterpillar will participate in these efforts at no cost to the government (they are internally funding their activities). In addition, Ultramet will be a subcontractor to ReJen on this proposed program, performing regenera- tor development and testing efforts.
