Abstract
A rotary combustion engine designed for operation as a stratified charge engine in which a relatively lean fuel-air mixture is supplied to each engine working chamber through the main air intake port and in which just prior to combustion in each engine working chamber, a relatively-rich, high-pressure, fuel-air mixture is supplied to each working chamber through individual passages in the rotor for each working chamber.
Claims7
A rotary combustion engine comprising:
- a. an outer body having an internal cavity, the peripheral surface of which has a multilobe profile and also having an air intake port and a combustion gas exhaust port,
- b. a shaft coaxial with said cavity and having a cylindrical eccentric portion disposed within said cavity,
- c. an inner body of generally polygonal profile and journaled on said eccentric portion for rotation within said outer body relative to said outer body and shaft, the apex portions of said inner body having sealing cooperation with said peripheral surface to define a plurality of working chambers which vary in volume in response to relative rotation of said inner and outer bodies with each peripheral surface portion of said inner body extending between adjacent apex portions forming a working face for the adjacent working chamber,
- d. first passage means for supplying a relatively lean fuel-air mixture to said working chambers through said intake port,
- e. second passage means for supplying a relatively fuel-rich charge to each working chamber after the lean mixture therein has been substantially compressed, said second passage means including individual passages in the inner body, one for each working chamber, with each of said individual passages having its downstream end terminating at the working face of its associated working chamber, and
- f. ignition means for initiating combustion in each working chamber in the region of said chamber containing said relatively rich charge.
