Variable-coordination-timing type self-cooling engine

Abstract

The present invention provides a variable-coordination-timing type self-cooling engine capable of adjusting the initiation timings and the injected amount of each injection process according to the change in the combusting pressure with the variable-coordinate-timing system. The variable-coordination-timing system will regulate the air flow between each coordinate-channel and its associated power-cylinder to optimize the cooling effects, and the hot-combusting-medium in each power-cylinder will be mixed with a flow of compressed air at a controlled rate and pressure, which prevents the hot-combusting-medium from charging into the primary-coordinate-channel and the secondary-coordinate-channel, thereby sustaining the cooling effects of the self-cooling-16-process in continuous high power output operation.

A variable-coordination-timing type self-cooling engine with variable-profile-camshaft as defined in  claim 11 , wherein, said three cylinders can be constructed in an asymmetrical 12-stroke-sequence to reduce the resonance vibration, and the dual-phase-difference can be between 315 degree and 405 degree. 
   
   
       20 . A variable-coordination-timing type self-cooling engine with variable-profile-camshaft as defined in  claim 11 , wherein said primary-power-cylinder and said-secondary-power-cylinder and said cooling-cylinder can be constructed in the double-crankshaft configuration; said primary-power-cylinder and said secondary-power-cylinder are connected to a main-crankshaft, and said cooling-cylinder is connected to a cooling-crankshaft, and said cooling-crankshaft is coupled and synchronized with said main-crankshaft with gears or chains to rotate at the same speed.
