Definitions

  • FIG. 3 This condition of the chambers 5,6 is seen in FIG. 3.
  • the engine casing not itself seen in FIG. 3, has half as many intake ports 14 and exhaust ports 13 as there are pistons in each set, and only one port 13, 14 is shown in FIG. 3.
  • the direction of movement of the piston 1 relative to the casing is from the right to the left, as indicated by an arrow in FIG. 3.
  • the chamber 5 has reached its smallest volume and moved out of communication with the exhaust port 13.
  • the piston 11 will clear the port 14 and move away from the piston l to expand the chamber 5 while the latter communicates with the intake port 14 and the source of fuel mixture connected therewith, but not shown since it may be entirely conventional. Communication between the intake port 14 and the expanding chamber 5 is maintained through the duct 3 while the piston 1 travels over the portion of the casing face containing the port 14.
  • the two ports 16, 17 may be connected with separate exhaust systems or with respective conduits in a jet pump arrangement as disclosed and claimed in the simultaneously filed application for an Exhaust arrangement in a rotarypiston, internal-combustion engine, Ser. No. 284,897.
  • each piston in said one set being formed with two duets open in respective opposite circumferential directions toward respective combustion chambers while being sealed from the respective other combustion chambers, each duct having an opening directed toward said casing, a portion of said circumferential face extending between each opening and the associated other combustion chamber, said openings being located in respective axially spaced radial planes;
