The application discloses an energy-saving natural gas internal combustion generator set, which is characterized by comprising a box shell, a generator set whole, an exhaust device, a filtering device and a preheating device; any side surface of the box shell in the width direction is provided with an air inlet, and the length direction side surface is provided with an air outlet; the exhaust device comprises an exhaust pipeline which extends upwards to the top of the box shell; the preheating device is arranged on the side surface of the box shell of the air inlet and is communicated with the air inlet; the preheating device comprises a plurality of heat exchange pipelines, and the gaps between the heat exchange pipelines are used for gas flow, so that the gas outside the box shell enters the box shell through the gaps; the preheating device further comprises an air inlet part and an air outlet part which are communicated with the two ends of the heat exchange pipelines; the air inlet part extends into the box shell and is communicated with the exhaust pipeline, and the air outlet part is communicated with the exhaust pipeline outside the box shell, so that the hot gas in the exhaust pipeline is introduced into the air channel and then is discharged into the exhaust pipeline through the air outlet part, thereby heating the cold gas flowing through the gaps and improving the temperature of the gas entering the box shell.
