The present invention provides an integrated engine system; said integrated engine system includes an air-compression means, an air-buffer-system, a power-management-unit, and at least two cold-expansion-chambers; wherein each of said at least two cold-expansion-chamber includes a spark- ignition means, a fuel-supplying means, a cold-air-injection means, and a reenergize- air-injection means; each cold-expansion-chamber operates in 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 active-exhaust-process; wherein the fuel- cooling-process may be disabled according to the operation condition. The air-buffer-system buffers a cooled high-boost-air for said cold-air- injection means and a heated high-boost-air for said reenergize-air-injection means; said power-management- unit includes sensor means and computation circuits to drive said fuel-supplying means, said cold- air-injection means, said reenergize-air-injection, and said spark-ignition means in order to maximize the energy efficiency of the Mackay Cold-Expansion Cycle, such that a cold-expansion- medium produces power in a controlled-temperature oxygen-rich condition; wherein the average medium temperature is reduced by 30%-80% to block heat-loss during the second-intake-process, and all the carbon-monoxide-gas of said cold-expansion-medium is spontaneously reacted with an excessive oxygen-gas during the cold-expansion-process, thereby fully releasing the energy of the supplied fuel by an accelerated conversion of carbon-dioxide-gas before the cold-expansion-medium is expelled out of the associated cold-expansion-chamber; wherein, the average temperature of said cold-expansion-medium is regulated within the range of 400-1100 degree Celsius by the power- management-unit, in order to efficiently produce power at a slowly-decreasing expansion pressure with the least heat-loss. Furthermore said air-buffer-system recovers the thermal energy from a heat- transfer-catalytic-converter, which utilizes the thermal energy of the expelled cold-expansion-medium to heat up a high-boost-air for the second-intake-process; thereby the energy efficiency is increased in a heavy load operation by reducing the workload on the air-compression means, and the temperature of the expelled cold-expansion-medium is maintained at an operable temperature of the catalytic-conversion means in a light load operation without comprising the energy efficiency.
