(1) Intake process: The motor drives the rotor. When the groove space of the main and slave rotors is turned to the opening of the intake end wall, the space is large, and the outside air is filled therein. When the intake side of the rotor is turned away from the shell At the air inlet, the air between the teeth is closed between the main and the slave rotor and the casing to complete the inhalation process.
(2) Compression process: At the end of inhalation, the closed volume formed by the main and slave rotor peaks and the casing decreases as the rotor angle changes, and moves in a spiral shape, which is the “compression process”.
(3) Compressed gas and fuel injection process: During the conveying process, the volume is continuously reduced, the gas is continuously compressed, the pressure is increased, the temperature is raised, and at the same time, the lubrication which becomes misty due to the difference in pressure is injected into the compression chamber, thereby Achieve compression, reduce temperature sealing and lubrication.
(4) Exhaust process: When the closed tooth peak of the rotor rotates to meet the exhaust port of the casing, the compressed air begins to discharge until the matching surface of the tooth peak and the groove moves to the exhaust end face, at this time the groove The space is zero, that is, the exhaust process is completed. At the same time, the other pair of teeth of the main and slave rotors have been rotated to the intake end to form a maximum space, and the inhalation process is started, thereby starting a new compression cycle.
