Abstract
This paper compares the desirable and undesirable characteristics of the rotary engine as an automobile powerplant. It is pointed out that in order for the engine to become an inexpensive automobile powerplant, certain seal design parameters should be changed to reduce tolerances required and to eliminate the costly, difficult-to-machine coatings on the trochoid and end-housing running surfaces. An analysis of the loads on the apex seal has been made and design parameters set up for a material to eliminate, or greatly reduce, the well-known chatter problem.
The authors have analyzed the geometry of the side compression and oil seals and propose changes in geometry and design of the seals to allow for automated assembly procedures.
