Abstract

PURPOSE: To improve fuel consumption and to prevent mechanical loss by a method wherein when combustion is stopped in part of the cylinders of a multiple cylinder engine and made in the rest the combustion chambers of the said part of the cylinders are made in the output priority type and the others in the eddy current tape or the turbulence type.
CONSTITUTION: Combustion is stopped according to running states in cylinder group A or in part 4, 10 of a plurality of cylinders 4, 6, 8, 10 while combustion always continues in cylinder group B or in the rest 6, 8. Besides, to a combustion chambers 18 of cylinder group B, a main suction passage 46 having a main suction valve 58 of relatively large area and a carburetor 14 having a sub-suction passage 44 with a sub-suction valve 56 of relatively small area are connected. In the said constitution, in time of a drive under low speed and load, combustion is stopped in cylinder group A and turbulent suction air is supplied to the combustion chamber 18 through the sub-suction valve 56 only of cylinder group B. Accordingly, in comparison with combustion operations in all cylinders the opening of the valve 56 increases, the loss of the pump reduces and the heat efficiency improves.
