Patent GB-1539166-A (GB)
Title: Internal combustion engine
IPC: F01N5/02
Filed: 1977-06-17
Abstract: The internal combustion engine system has an internal combustion engine (1) with a supercharger assembly (3, 10) and a closed steam circuit (16) with a heat exchanger (9), a steam turbine (15), a condenser (17) and a feed pump (18). Due to the fact that the heat exchanger acting as vaporiser and superheater is arranged upstream of the exhaust turbine (10), in the exhaust gas direction of flow, the temperature difference between exhaust gases and steam at the heat exchanger is greater and the inlet temperature at the exhaust turbine (10) is lower. Less expensive materials can therefore be used and greater efficiency achieved. The heat exchanger can be compactly attached to the engine. An auxiliary steam boiler can be provided in order to increase the power output of the steam turbine. <IMAGE>

C. engine of the rotaryabutment type includes a two-lobed piston 22, Fig. 2a, which is lodged within a stationary cylindrical casing containing abutment rotors 20, 21 on diametrally-opposite sides of the piston, the rotor 20 being situated within a recess or cylinder 18 between inlet and outlet ports for working fluid whereas the other rotor is situated in a recess or cylinder that serves as a combustion chamber wherein compressed fuel-air mixture is ignited by a spark-plug 14. The rotors 20, 21 are connected to the piston by toothed gearing 9, 10 so that they rotate in the same direction as the piston in synchronism therewith. In a second embodiment, Fig. 5, the piston 50 is hollow and surrounds a stationary cylinder 61 containing abutment rotors 20, 21, the rotor 20 being situated between inlet and outlet ports 23a, 28a. The inner peripheral surface of the piston contains two diametrally-opposed lobes or depressions 25a, 26a. The engine may be modified for compressionignition operation and may comprise more than two, abutment rotors, Figs.3 and 10 (not shown), the piston being furnished with a corresponding plurality of lobes. The engine may be adapted to effect compression of air in one of the working spaces between the piston and the casing, Fig. 7 (not shown), the air being drawn through a port (45) adjacent one rotor and ejected through a port (26) adjacent one of the other rotors after compression in a working space lying between said rotors. The profile of each rotor may include three lobes, Fig. 8 (not shown); and the rotor or rotors 20 may rotate in a direction opposite to that of the rotation of the piston. The inlet and outlet ports may be situated in an end wall of one of the recesses wherein the rotors are lodged, Fig. 11 (not shown), so that they are controlled by the associated rotor. A plurality of pistons may be arranged on a common shaft, Fig.4 (not shown), and the rotors associated therewith may be arranged to be 180 degrees outof-phase relative to each other. The profiles of the walls of passages associated with the inlet and outlet ports may be modified, Fig. 6 (not shown).
