| Abstract;In the previous study, the authors found that by moving the piston slowly around top dead center, degree of constant volume increased, but thermal efficiency was not improved due to increased heat loss. Consequently, direct injection stratified charge combustion was tested to selectively reduce heat loss, and an improvement of thermal efficiency was achieved at this time. Moreover, when pre-mixed spark ignition combustion is completed in a short time with quick combustion, increasing the piston speed around top dead center rather than moving the piston slowly was found favorable to improve thermal efficiency.
