Organic　Rankine　cycle　(ORC)　technology　can　convert　the　exhaust　heat　energy　from　engines　into　mechanical　energy　or　electrical　power　efficiently　to　improve　the　efficiency　of　vehicle　engines.　In　this　paper,　the　development　of　ORC　waste　heat　recovery　technology　for　vehicle　engines　was　studied,　with　a　focus　on　numerical　simulations,　control　strategy　and　key　components　(expander,　heat　exchanger　and　pump).　The　future　development　and　prospect　were　also　put　forward.　Results　show　that　recovering　exhaust　heat　energy　from　vehicle　engines　by　the　ORC　system　has　a　broader　development　perspective.　However,　at　present,　the　dynamic　matching　characteristics　of　the　vehicle　engine　and　ORC　system　under　working　conditions,　three-dimensional　simulation　and　experimental　test　of　ORC　waste　heat　recovery　system　for　vehicle　engines,　and　optimum　design　of　key　components　suitable　for　the　system,　etc.,　still　need　further　research.　The　development　of　high　performance　components,　highly　integrated　experiment　and　simulation,　and　intelligent　control　strategy　of　the　ORC　waste　heat　recovery　system　for　vehicle　engines　will　be　the　prevailing　trend.　©　2019,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
