  5. 5. ENGINE CLASSIFICATION
  6. 6. INTERNAL COMBUSTION ENGINES Wankel engines • 3 LOBE ROTOR WHICH IS DRIVEN ECCENTRICALLY IN A CASING & 3 VOLUMES ARE TRAPPED BETWEEN THE ROTOR AND THE CASING. THESE VOLUMES PERFORM INDUCTION, COMPRESSION, POWER & EXHAUST STROKES SEPERATELY. • SEAL WEAR & HEAT TRANSFER ARE PROBLEM AREAS ROTARY
