A combustion control system for an engine having an intake manifold with a throttle, a PCV gas inlet opening into the intake manifold, an exhaust conduit, and a PCV gas conduit. A vortex device has a vortex chamber with a tangential inlet connected to the PCV gas conduit, an axial inlet, and an axial outlet connected directly to the PCV gas inlet opening of the intake manifold. A reactor device has a gas inlet connected directly to the exhaust conduit for drawing gas therefrom and an outlet spaced well apart from the vortex device and connected to the axial inlet of the vortex device by a conduit. The reactor device includes a first ejector for drawing in atmospheric air and mixing it with gas from the exhaust conduit, and a second ejector for drawing in liquid from a source of liquid and sending it into the atmospheric air drawn in by the first ejector means. The vortex device and the reactor are novel in themselves too.
