The driving method specifically comprises the steps of collecting information such as the current vehicle speed, the endurance mileage and the supply station, and realizing the following scenes through an air energy heat insulation external combustion power system: firstly, the method has the advantages of having a cruising risk, increasing fuel input, reducing compressed air consumption, and forming high-temperature high-pressure gas to drive a piston connecting rod mechanism to do work by using a theoretical air-fuel ratio. Secondly, the compressed air can arrive at a compressed air supply station normally, the supply time is short, and the medium-temperature high-pressure gas is formed to push a piston connecting rod mechanism to do work by utilizing an ultra-lean combustion technology (mainly compressed air, and a small amount of fuel oil is combusted locally to assist in endurance). Time is abundant, compressed air supply stations are reasonably distributed, and the piston connecting rod mechanism can burn at low temperature by using trace fuel oil, so that the piston connecting rod mechanism is guaranteed to work in a low-friction high-efficiency area.
