A　gasoline　rotary　engine　enriched　with　directly　injected　hydrogen　could　be　regarded　as　an　appealing　option　to　improve　combustion　efficiency　while　reducing　emissions.　In　this　paper,　a　three-dimensional　dynamic　simulation　model　coupling　with　the　chemical　kinetic　mechanisms　was　established　using　CONVERGE　software　and　validated　by　the　experimental　data.　The　numerical　model　was　implemented　for　evaluating　the　influences　of　varying　duel　spark　plug　locations　on　flow　field　distributions,　combustion　processes　and　major　emissions　formation　of　a　gasoline　rotary　engine　with　hydrogen　direct　injection　enrichment.　Simulation　results　showed　that,　a　mainstream　flow　field　formed　during　the　end　period　of　the　compression　stoke　whose　direction　was　identical　to　the　rotor　rotating　direction.　The　variation　of　trailing-spark　plug　location　resulted　in　slight　influence　on　the　mean　flow　velocity　as　well　as　notable　impact　on　hydrogen　concentration　and　turbulent　kinetic　energy　distribution.　It　was　conducive　to　initial　ignition　when　the　local　equivalence　ratio　was　intensified　near　the　duel-spark　plug　on　the　leading　side　of　the　combustion　chamber.　Higher　hydrogen　concentration　near　spark　plugs　could　effectively　improve　the　combustion　intensity.　The　preferable　combustion　and　emission　performance　were　achieved　when　the　duel-spark　plug　positioned　symmetrically　with　respect　to　the　minor　axis.　Compared　with　the　scheme　of　the　closest　duel-spark　plug,　the　peak　pressure　increased　by　24.4%　and　corresponding　crank　position　advanced　by　9.2　degrees　CA.　Despite　nitric　oxides　emissions　increased　slightly,　carbon　monoxide　emission　notably　reduced　by　57.6%　versus　the　scheme　of　the　farthest　duel-spark　plug.　When　the　leading-spark　plug　remained　constant,　the　trailing　spark　plug　arranged　on　the　major　axis　of　cylinder　wall　and　kept　an　appropriate　offset　from　the　minor　axis　was　recommended　in　engineering　applications.
