The invention relates to a loading machine, and specifically relates to an energy-saving loading machine. The loading machine comprises a loading machine body, and also comprises a microcontroller andan ozone generation device. The microcontroller is connected with a power supply of the loading machine. The ozone generation device is connected with the microcontroller. The ozone generation deviceis arranged on an inlet of an internal combustion engine. The ozone generation device of the loading machine generates ozone, so that oxygen in the internal combustion engine is increased, and the loading machine has good energy-saving effect.
