摘要：

The　integrated　simulation　model　of　vehicle　engine-organic　Rankine　cycle　combined　system　was　built　by　using　GT-Suite　software.　The　influence　of　the　speed　of　pump　on　the　performance　of　the　combined　system　was　studied　based　on　the　simulation　model,　the　speed　of　pump　was　optimized　by　using　genetic　algorithm,　and　running　mode　for　combined　system　was　determined　according　to　the　analysis　results.　The　results　show　that　the　optimal　pump　speed　is　about　1000　r/min　under　the　low　load　region　of　engine.　When　the　engine　speed　is　higher　than　1800　r/min,　the　optimal　pump　speed　increases　with　the　engine　load.　At　the　engine　rated　condition,　the　thermal　efficiency　of　combined　system　is　higher　than　that　of　original　engine　by　3.　57%,　and　the　brake　specific　fuel　consumption　(BSFC)　of　combined　system　decreases　by　10.　09　g/kWh.　©　2019,　Editorial　Board　of　Acta　Energiae　Solaris　Sinica.　All　right　reserved.
