[0021] When used specifically, the specific process is as follows: Turn on the start button, connect the starter motor power supply and start working. The V-belt pulley at the output end of the starter motor drives the double V-belt pulley (V-belt on V-belt pulley 1) at the left end of the engine crankshaft output end to rotate by the V-belt, and then turn on the air pressure and volume control switch (referred to as "switch"). At this time, the compressed air (high-pressure driving gas) enters the "common rail" (shared by four cylinders) from the static high-pressure energy storage container through the air pressure and volume control switch, and then enters the high-pressure chamber of the valve mechanism through four gas zero dividers. After the gas switch is switched (turned on), the compressed air enters the top dead center of the cylinder (the top dead center of cylinders 1 and 4) respectively. At this time, the 15MPa high-pressure driving gas pushes the piston to make a stroke motion. During the return motion, the switch opens the exhaust valve to discharge the gas. At this time, cylinders 2 and 3 are the same as above, and so on, and the engine starts.
