ABSTRACT:
An internal combustion engine is disclosed which includes active and inactive cylinders, an intake passage divided into first and second branches leading to the active and inactive cylinders, respectively, valve means provided at the entrance of the second intake passage, and fuel supply means for supplying a controlled amount of fuel into the active and inactive cylinders. A load detector is provided for detecting engine load to provide a low load indication signal to the fuel supply means which thereby cuts off the supply of fuel to the inactive cylinders and also to the valve means which thereby cuts off the flow of air to the inactive cylinders. Delay means is provided for delaying the start and end of application of the low load indication signal to the fuel supply means.
