A combustion control system for an automotive engine in a vehicle. A sidestream exhaust gas tube has a scoop inlet in the engine's exhaust-gas conduit. A first metallic tube portion leads from the scoop to a point forward of the vehicle's radiator, so that it directly receives ambient air on its exterior surface, thereby cooling the exhaust gas to near ambient-temperature. A water trap then removes condensed water from the sidestream exhaust gas, along with entrained particles. A final insulating tube portion extends rearwardly of the radiator and helps to limit reheating of the cooled exhaust gas while conducting it to a reactor device. There, an inlet for the exhaust gas receives the cooled exhaust gas and conducts it to first ejector for drawing in aqueous liquid and to a second ejector for drawing in atmospheric air and mixing it with the gas-liquid mixture from the first ejector. The reactor's outlet is connected to an axial inlet of a device having a vortex chamber with a tangential inlet connected to a gas supply at substantially atmospheric pressure. An axial outlet from the vortex chamber is connected directly to a gas inlet opening of the engine, leading to the intake manifold, which is free from obstructions and leads in one chamber to the intake valves of all cylinders or combustion chambers.
