Abstract:
1. A Cold-Expansion Engine System comprising: a) at least two cold-expansion-chambers and a power-management-unit, wherein each cold-expansion-chamber includes a piston, a cold-air-injection means, a reenergize-air-injection means, a fuel-supplying means, a spark-ignition means, and an exhaust-means; b) a cold-buffer for buffering a cooled compressed-air to the cold-air-injection means of said at least two cold-expansion-chambers; c) a reenergize-buffer for buffering a heated compressed-air to the reenergize-air-injection means of said at least two cold-expansion-chambers; d) an air-compressor and a compressor-transmission means for providing compressed-air; and e) said power-management-unit controls all said cold-air-injection means, reenergize-air-injection means, fuel-supplying means, and compressor-transmission to operate each cold-expansion-chamber in a Cold-Expansion Cycle consisting of a first-intake-process, a hot-combustion-process, a fuel-cooling-process, a second-intake-process, a cold-expansion-process, and an exhaust-process, wherein:
