Authors Abstract
Content
The problem of finding the cylinder pressure trace which maximizes engine efficiency is formulated in terras of cylinder pressure-dependent frictional, heat, and mass losses. The governing equations are recast into a form to which optimal control theory can be applied, and the pressure trace together with the corresponding optimum heat release profile which yield maximum efficiency are found. Results for optimum heat release are compared to results for both conventional rates of heat release and for the theoretical Otto cycle, and show that significant gains in efficiency are possible if the optimum heat release is employed.
