[0002] An engine is a machine that converts other forms of energy into mechanical energy. These include internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, and electric motors. Internal combustion engines typically convert chemical energy into mechanical energy, and the engine intake pipe is the air pipe that guides the gas required for combustion into the engine. The intake pipe must ensure sufficient flow area, avoid turns and sudden changes in cross-section, and improve the surface finish of the pipe to reduce resistance. Traditional airtightness testing tools are mostly liquid tests when testing pipe fittings. The airtightness is determined by whether there are bubbles when penetrating the pipe.
