Abstract
This combustion control system adds a fluid and heat energy to the air-fuel mixture of the induction system of an internal combustion engine in response to engine need to improve combustion, to increase power, to improve efficiency, and to reduce emissions. Fluidic control mechanisms provide the control functions without any moving parts. A vortex chamber serves as a main variable impedance control mechanism. The outlet of the vortex chamber is connected to the positive crankcase ventilation (PCV) inlet to intake manifold downstream of the butterfly valve. The vortex chamber has a tangential input for PCV gases and an axial input for supplying air, aqueous fluid, and exhaust gases, all for mixing within the vortex chamber and transmitted to the intake manifold. The exhaust gases are conducted to the vortex via two parallel ejectors, one of which sends water or vapor across a gap to mix with intake air that is sucked into the exhaust gases by the other ejector.
