A fuel-conditioning-method and coupled-combustion process incorporated into internal combustion engines minimizes exhaust emission and improves fuel economy. Gasification chamber 10 affixed into piston 12 is placed under piston crown 14, transfer port 18 carved into cylinder 20 wall connects into combustion chamber 22, arrow 26 indicates that gasified fuel is transferred from chamber 10 into combustion chamber 22 initiating combustion. When pressure inside combustion chamber 22 is higher than that inside chamber 10 a reverse flow fills chamber 10 with hot combustion gases. During piston 12 downstroke gasification chamber inlet/outlet 34 overpass bottom edge 36 part of transfer port 18, therefore hot combustion gases are shut close inside chamber 10 by cylinder 20 wall. When piston 12 is at BDC fuel injector 24 injects fuel that absorbs heat from entrapped combustion gases vaporizing. During piston upstroke gasification chamber inlet/outlet 34 reaches the bottom edge 36 and the cycle repeats. |
