ABSTRACT:
A rotary piston internal combustion engine of the epitrochoidal type is provided with means whereby the cooling effect of a cooling liquid medium on a trailing chamber portion of the combustion chamber is reduced or eliminated. Thus a tendency that the mixture portion within the trailing chamber portion is discharged unburned with the exhaust is eliminated, thus improving the fuel economy and HC control in the exhaust.
