Abstract: The combustion characteristics of Wankel rotary engines, especially
     the flame propagation and knocking phenomena, are different from those of
     reciprocating engines because of the difference in engine mechanisms.
     Flame propagation and knocking phenomena of both one- and two-spark-plug
     rotary engines have been studied using high-speed photography, the ionized
     gap method, and a combustion simulation model. The influence of squish
     flow on flame propagation and places where knocking occurs have been
     clarified. The effects of spark plug location, ignition timing, and
     combustion chamber (recess) shape on flame propagation have also been
     investigated. The relation between knocking and emissions is discussed,
     and the overall results are summarized.
