ABSTRACT:
A dual rotor type rotary engine with primary and secondary rotor compartments around each rotor is described. The engine operates by activating in sequence an ignition means in the presence of a fuel and air mixture in primary and secondary compartments around one rotor and in primary and secondary rotor compartments around the other rotor. The engine is provided with a central housing between the rotors having a confined space for receiving hot exhaust gases from primary rotor compartments, for mixing with air introduced into the confined space and for conveying the mixture to secondary rotor compartments. The fuel, air and hot exhaust gas mixture in the secondary rotor compartments operates on a reduced amount of fuel by comparison to the fuel and air mixture in the primary compartments. The central housing preferably has air inlets on either side of the confined space to heat inlet air supplied to the primary rotor compartments by heat transfer from the hot surfaces and exhaust gases. The rotary engine is also provided (1) with rotary inlet and outlet valve means into and from the primary and secondary rotor compartments preferably in the form of rotary inlet valve tubes and outlet valve tubes with openings for supplying air or air mixed with hot exhaust gases to the compartments and for removing hot exhaust gases from both compartments and (2) preferably with inlet and exhaust gas manifolds for common inletting to and exhausting of gases from the rotor compartments through the valve tubes.
