PURPOSE:To improve combustion efficiency of an engine with simple construction, by mutually communicating compression chambers through a communication passage, providing a fuel supply means in this communication passage, opening a communication port only in the leading side of the compression chamber and stratifying supply air. CONSTITUTION:Rotor housings 1, 1' are arranged in both sides of a side housing 3, and a communication port 4 is formed in the side housing 3 then connected by a communication passage 6. This communication port 4 is placed in the leading side of a compression chamber and arranged in a position where the port is opened by a rotor 2, about the time the rotor 2 closes an intake port 5, while in a position where the port is closed by the rotor 2 before an ignition plug 19 is fired. Further the rotor 2 and rotor 2a are rotated at a phase angle of 180 deg., and an injector 8 is provided in the communication passage 6, then fuel is injected through a computer 80 in accordance with an air flow quantity detected by an air flow meter 10. In this way, the fuel, injected from the injector 8, can be fully mixed with air in the communication passage 6 and fed into the compression chamber. |
