Abstract: 1433457 Rotary IC engines NISSAN MOTOR CO Ltd 10 April 1974 [17 April 1973] 15862/74 Heading F1F In an engine that may be of the biochoidal type with four working chambers V1 ÀÀ V4 the working cycle of each chamber has seven phases viz three additional phases between the third and fourth phases of the usual I.C. engine cycle. During the first of the additional phases partially expanded combustion products are transferred from the respective one of the chambers (say V1) through e.g. a recess 32 in an outer member 12, to another of the chambers, which is preferably the leading adjacent chamber V2. During the second of the additional phases secondary air is introduced to the chamber V1 through e.g. a port 36 controlled by a cam-operated valve 38, to scavenge the chamber and expel spent combustion products into the said other of the chambers. During the third of the additional phases partially expanded combustion products are transferred through e.g. the recess 32, to the chamber V1 from a further one of the chambers, which is preferably the trailing adjacent chamber V4, there to mingle with the previously inducted secondary air and thus effect further oxidation of components of the said combustion products such as carbon monoxide. The secondary air may be supplied by an enginedriven pump 40. Inlet and outlet ports 26, 28 and a spark-plug 34 may be disposed as shown. The inlet port 26 may be replaced with two separate ports for rich and lean fuel-air mixtures, respectively. The entire working cycle of the embodiment according to Fig. 2 is described with reference to Figs. 1A to 1L (not shown). In a second embodiment, Fig. 3, the port 36 is an end-wall of the member 12 and corresponding ports 44 in the piston 14 communicate with the working chambers through recesses 46 in the convex faces of the piston. A third embodiment, Fig. 4 (not shown), differs from the second one largely in that oblique passages (48) inter-connect the ports 44 arid recesses 46 to improve the scavenging by secondary air.

In the embodiment of Fig. 1 an irradiation channel 4 extends between the reactors which are separated by a neutron shield 3. A test specimen 5 can be moved from initial position 7 in reactor 1 where it achieves a temperature distribution equivalent to that of a normal reactor environment, to a position 8 in reactor 2 where it receives a pulsed neutron flux simulating an overload condition in the normal reactor environment. Initiation of the pulse is automatic in response to movement of the speciment to position 8. Coolant in channel 4 may flow in a closed loop (independent of coolant for the reactors 1, 2) or an open loop. In the embodiment of Fig. 2 the specimen remains stationary in the irradiation channel which extends through a gap between the reactors. Instead, a tubular neutron shield 9, part of which provides a neutron window, is rotatable through 180 degrees to expose the specimen firstly to reactor 1 and subsequently to the pulsed reactor 2. In a modification the neutron shield 9 has opposite but axially offset neutron-absorbing portions and is movable axially, without rotation, to expose the specimen. The test specimens may be reactor fuel elements or other reactor components.
