Due　to　the　elongated　shape　of　the　combustion　chamber　and　strong　one-way　flow　characteristic,　changing　the　location　of　enhanced　combustion　is　an　effective　means　to　ameliorate　the　indicated　efficiency　of　the　Wankel　engine.　For　this　purpose,　strengthening　combustion　can　happen　by　allocating　spark-energy　in　the　desired　location　along　with　a　favorable　ignition　environment.　In　this　study,　three-dimensional　CFD　simulations　were　implemented　and　the　numerical　results　were　compared　with　existing　measured　data,　in　which　ignition　environment　variations　were　achieved　by　hydrogen　enrichment　within　the　intake　manifold　of　a　spark-ignition　Wankel　engine.　Based　on　CONVERGE　code　with　the　SAGE　detailed　chemistry　solver,　the　twin-plug　engine　model　was　then　used　to　assess　the　location　of　strengthened　combustion　employing　a　spark-energy　allocation　from　the　perspective　of　species　evolution,　combustion　characteristics,　and　emissions　formation.　The　results　indicate　that　enhancing　spark-energy　at　the　leading　side　of　the　rotor　chamber　has　an　overall　higher　burned　volume　rate　and　faster　species　evolution　due　to　the　later　connection　of　two　burning　sources　prior　to　quenching.　Increasing　the　hydrogen　content　in　the　ignition　environment　causes　richer　active　radicals　and　higher　turbulence,　ultimately　promoting　flame　propagation　and　combustion　intensity.　A　larger　T-plug　spark-energy　decreases　the　indicated　mean　effective　pressure,　heat　release　rate,　and　thermal　efficiency　because　of　the　intensified　wall　heat　flux　and　the　lower　mass　burning　rate　at　the　leading　side.　There　is　no　doubt　that　the　introduction　of　hydrogen　enrichment　presents　a　positive　effect　on　both　thermal　efficiency　and　specific　fuel　consumption　at　the　price　of　a　slighter　increase　of　nitrogen　oxide　formation　due　to　higher　mass　fraction　of　high-temperature　regions.　It　is　recommended　that　enhancing　local　mass　burning　rate　in　the　leading　part　of　the　rotor　chamber　under　the　hydrogen-enriched　ignition　environment　can　provide　a　great　potential　in　the　quest　towards　high-efficiency　Wankel　rotary　engine.
