Abstract: Rotating bar within eccentric wheel was previously invented. But that was only suitable for pumps. In my proposed invention I used two dissimilar bars of same length named as prime mover and follower which are incorporated within eccentric wheel. The follower bar-end is hinged with prime mover bar-end while that prime mover bar-end is fixed at the centre of the circular housing named as power shaft. Prime mover rotates the eccentric wheel and that wheel rotates the follower the hinged joints and this assembly rotation creates differential volume repetitively and spark in compression stage creates combustion. This principle of engine operation also includes different sealing types and outward opening type cam assembly. In conventional reciprocating engine lots of power is lost because of change of direction of piston motion. This problem can be overcome by my proposed engine design which will lead to higher efficiency in automobile.
