When the gear piston and the combined gas ring 9 run to the gas high-pressure area 5, the gear piston contracts inwards under the action of a reaction spring and high-pressure gas, the mixed gas is driven to run to the combustion area 8, the gas is compressed under the action of a cam, when an additional spark plug is used for ignition, an engine explodes, and a large gear moves anticlockwise under the action of inertia (the small gear rotates clockwise); the mixed gas after burning is carried to an exhaust area 1, whether the mixed gas is burnt sufficiently is judged after the mixed gas is detected by a gas sensor, and whether the mixed gas is exhausted is determined. If the combustion is sufficient, the intelligent control system starts to control the valve to exhaust. Otherwise, the gas is not exhausted; the inertia effect of the mixing in the large gear brings the low pressure area into the high pressure area again, and the combustion … … again can determine whether to supply oil or not under intelligent control.
