ABSTRACT:
A sliding vane engine, where the vanes slide with at least of one of an axial and radial component of vane motion, and where the compression ratio of the engine may be variably controlled. The engine includes a stator and a rotor in relative rotation, and a plurality of vanes in rotor slits defining one or more main chamber cells and one or more vane slit cells. The vanes contain extended pins that move in a pin channel for controlling the sliding motion of the vane. Fuel is mixed by incorporating air turbulence generators at or near the intake region. The intake and exhaust regions of the engine also incorporate a wave pumping mechanism for injecting and scavenging air from the main chamber cells and the vane slits. The compression ratio of the engine may be varied while the engine is in operation, and the engine geometry provides for an extended temporal duration at about peak compression. The engine is insulated by using segmented ceramic inserts on the stator and rotor surfaces.
