Active-threshold-control type self-cooling engine

摘要

The present invention provides an active-threshold control system for the self-cooling engine to improve the energy efficiency of the self-cooling-16-process.;The active-threshold-control type self-cooling engine consists of a primary-power-cylinder and a secondary-power cylinder and a cooling-cylinder and an active-threshold-control system that controls the initiation timing of each injection-process with the active-cooling-phase, thereby limiting the maximum compression pressure in each coordinate-channel and reducing the energy loss during the first-cold-compression-process and the second-cold-compression-process.
