  • Exhaust stroke of the first engine block occurs when piston chamber No.1&2 complete its downward movement. While moving around to the exhaust port, the piston No.1&2 moves up again to expel the exhaust. When the piston No. 1&2 moves up to the top position, piston chamber No.1&2 will pass through and promptly close the exhaust port. At the same time the second engine block is operating in ignition stroke (Fig.17 No.83, 84, 85).
  • Piston chamber No.1 and No.2 comprise first engine block while piston chamber No.3 and No.4 form second engine block.

  • the ignition stage of each piston will substantially equal to no of piston in each engine block that are three, four, six and eight for 3,4,6,8 piston engines respectively.
  • a compressor is basically constructed with the same structure as that of internal combustion rotary engine, having cylindrical chamber; rotor with output shaft as its axis in cylindrical chamber; crankshaft, piston, piston chamber within rotor. Expanding piston chamber created by downward movement of piston draws fluid such as air through filter connected with suction port on outer cylinder. After compression, the fluid is driven out of the exhaust port through pipe to a storage tank for future use.
  • the compressor may be used to compress liquid or gas. While working as a compressor, the reciprocating piston will operate on two-stroke cycle, completing a cycle at each self-revolution of the piston chamber.
