An internal combustion engine is disclosed which is operable on less than all of its cylinders with recirculation of exhaust gases into the inactive cylinders under low load conditions. The engine has an intake passage provided therein with an air metering throttle valve and divided downstream of the throttle valve into first and second branches leading to the active and inactive cylinders, respectively. The second branch has therein valve means adapted to close so as to define a seal chamber with the inner surface of the second branch during a split engine operation. The seal chamber is communicated with the intake passage upstream of the throttle valve for introduction of air into the chamber.
