PURPOSE: To save fuel by making pistons of a pair of cylinders respectively reciprocation-movable with different phase, and spraying fuel with a fuel injector through a venturi extending between the two cylinders. CONSTITUTION: A pair of adjacent cylinders 15, 17 is arranged in a cylinder block 13, pistons 45, 47 are respectively reciprocation-movable with different phase. A fuel injector 51 is arranged in a cylindrical dent 141 between head ends 35, 37 of the cylinder head 33, the fuel from valve head 75 passes through cone branch passages 125, 127, further through a throat of the fuel passages 95a to 95c, 97a to 97c of the head 33, and is sprayed to the other cylinder by high pressure of one cylinder depending upon the open or close of the valve 71. Therefore, the fuel can be saved. |
