A first cylinder that is always in operation, a second cylinder that is stopped depending on the engine load, an air-fuel mixture supply means for supplying air-fuel mixture to these first and second cylinders, and the above-mentioned an atmospheric pipe capable of introducing fresh air into the second cylinder; an on-off valve provided on the intake side of the second cylinder; and an exhaust means for discharging exhaust gas from the first and second cylinders; The valve closes the atmospheric pipe and guides the air-fuel mixture to the second cylinder when the load is high;
A variable cylinder internal combustion engine characterized in that as the load decreases, introduction of the air-fuel mixture into the second cylinder is suppressed. 2. The air-fuel mixture supply means is an intake manifold that communicates with each other, the atmospheric pipe opens to the intake manifold, and the on-off valve is located in the intake manifold, and the atmospheric pipe is connected to the opening of the atmospheric pipe. A variable cylinder internal combustion engine according to claim 1, characterized in that the variable cylinder internal combustion engine is provided in the vicinity of the utility model. 3. The variable cylinder internal combustion engine according to claim 2, wherein the opening/closing valve is continuously driven to open and close by negative pressure in the intake manifold.
