The potential advantages of incorporating an extended expansion-stroke in Diesel engines are discussed. It is shown that Diesel engines with extended expansion strokes can be expected to have specific fuel consumptions up to about 8% lower, for typical automotive size units, than those achievable with conventional Diesel engines employing equal compression and expansion strokes. A description is also given of the essential mechanical linkage necessary to achieve an extended expansion stroke in engines of the four-stroke type. The application of the extended expansion concept to engines of the two-stroke, uniflow, type is also described.
