The present invention provides an integrated engine system; said integrated engine system includes an air-compressor, an air-buffer-system, a power-management-unit, and a cold-expansion-chamber for operating a Mackay Cold-Expansion cycle, which includes a first-intake-process, a hot-combustion-process, a fuel-cooling-process, a second-intake-process, a cold-expansion-process, and an exhaust-process; said air-buffer-system supplies a cooled compressed air to be injected during said first-intake-process, and a heated compressed air to be injected during said second-intake-process; an air-fuel mixture is ignited to produce a hot-expansion-medium during said hot-combustion process, and the hot-expansion-medium is cooled by a fuel vaporization and an injection of heated compressed air to produce a cold expansion medium at an optimal expansion temperature, thereby accelerating the conversion of carbon-monoxide to carbon dioxide in the cold-expansion-medium and reducing heat loss. |

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:
said cold-air-injection means and said fuel-supplying means supply an air-fuel-mixture in the first-intake-process;said air-fuel-mixture is ignited to form a hot-combustion-medium in the hot-combustion-process;said hot-combustion-medium is cooled by a fuel-injection in the fuel-cooling-process;said hot-combustion-medium further cooled, after the fuel-cooling-process, by injecting a heated compressed-air to form a cold-expansion-medium in the second-intake-process, wherein, the second-intake-process is commenced within a range between 30 degree after-top-dead-centre of the associated piston and 105 degree after-top-dead-centre of the associated piston; andsaid cold-expansion-medium produces power, with a spontaneous combustion of carbon-monoxide and oxygen at a temperature range of 400-1100 degree Celsius, in the cold-expansion-process. |
