ABSTRACT:
A rotary Wankel type engine system is disclosed, wherein the crankshaft is supported by a center main roller bearing. The rotor apexes are sealed by two piece apex seals and by side seals. The engine system further includes an oiling system which permits oil flow through the center bearing and through lubrication passages in the engine rotor to provide a means for cooling the engine rotor under high loading conditions. Riblets are defined in the combustion face of the rotor to promote aerodynamic lateral stratified charge control to minimize atomized fuel charge loss to surface wetting before ignition.
