PURPOSE:To improve the stability of an engine during high speed running to a very high degree without increasing the amount of green gas injection by providing to an inner face of a valve body of a rotary valve mechanism a rotary fin for pressure feeding suction green gas into a cylinder. CONSTITUTION:If a rotary valve 12 is rotated through a driving sprocket 14 in synchronism with predetermined motion of a piston 24 of a cylinder 23, a suction port 6 or A portion of the rotary valve 12 and the cylinder 23 are brought into communication to each other, allowing green gas delivered from a fuel injector through a suction manifold 21 to be supplied into the cylinder 23 by utilizing negative pressure generated during a downward movement of the piston 24 and also by forcible feeding by rotation of fins 8. Thus, since green gas is forcibly fed into the cylinder 23, starting of rotation of the engine is improved thereby and also a high output power can be obtained thereby. |
