Abstract

1,032,776. Rotary piston fuel-injection engines. CURTISS-WRIGHT CORPORATION. April 30, 1963 [May 1, 1962], No. 17021/63. Heading F1F. A rotary piston fuel-injection engine comprising an outer body 12, Fig. 1, (not shown), having an epitrochoidal, two-lobed inner profile 26 and a three-sided inner body 16 eccentrically mounted with respect to the axis 18 of the outer body to be planetarily revolvable within the outer body includes in the outer body on either side of one lobe junction 43 an intake port 40 and an exhaust port 42 and adjacent the other lobe junction 48 a recess 64 into which extends at an acute angle to each other a fuel-injection nozzle 46 and a spark-plug 44. Fuel injection is initiated when the volume of a working chamber 34a, 34b, 34c is at a minimum and ignition is substantially instantaneous with injection. Rate and duration of fuel injection is in accordance with the air mass flow past the point of injection and terminates prior to the completion of this flow and so it is stated permits the use of a wide variety of fuels. In one embodiment, Fig. 3, the nozzle 46 and plug 44 are located in a common recess 64 downstream of the point 48 in the direction of rotation of the inner body 16 with the nozzle directed to spray in an upstream direction and the electrodes of the spark-plug adjacent the periphery of the jet. The pressure differential acting on an apex sealing strip on passing this location is substantially zero. Between the nozzle and plug a cooling duct 68 is arranged. In another embodiment, Fig. 9, (not shown), the nozzle 46<SP>1</SP> and plug 44<SP>1</SP> are located in a common recess 64<SP>1</SP> upstream of the point 48<SP>1</SP> in the direction of rotation of the inner body 16 with the nozzle directed to spray in a downstream direction. The combustion chamber 72, Fig. 3, and 72<SP>1</SP> Fig. 9, one in each flank of the inner body, are located such that air is supplied to support the main portion of combustion shortly after "top dead centre" to improve performance and efficiency. The combustion chamber 72 is reversed with respect to the chamber 72<SP>1</SP> and located somewhat nearer the leading edge of the inner body flank. In a further embodiment, the nozzle 46<SP>11</SP>, Fig. 14 (not shown), and the plug 44<SP>11</SP> are located side-by-side transversely in the outer body and open into a common recess 64<SP>11</SP> giving a wide angle of spray for the jet.
