ABSTRACT:
An internal combustion engine is disclosed which comprises first and second cylinder units each including at least one cylinder, an intake manifold divided into first and second intake passages leading to the first and second cylinder units, respectively, and an exhaust passage leading from the first and second cylinder units. The second intake passage has therein a normally open stop valve. The second intake passage is connected to the exhaust passage through an EGR passage having therein a normally closed EGR valve. Control means is provided for providing a control signal to disable the second cylinder unit when the engine load is below a predetermined value. The control signal is applied to valve drive means which thereby closes the stop valve and opens the EGR valve. The valve drive means is constructed to prevent the simultaneous opening of the stop and EGR valves.
