The　vehicle　being　ignited　in　tunnel　fire　could　disturb　the　temperature　distribution　and　result　in　more　serious　hazards.　However,　the　temperature　profile　about　the　tunnel　fire　with　an　ignited　vehicle　has　not　been　clarified.　This　paper　conducted　a　series　of　1/6　small　scale　experiments　with　different　heat　release　rates　to　investigate　the　vehicle　ignition　time　delay　and　temperature　profile.　The　longitudinal　ventilation　velocity　varied　from　0.5　m/s　to　2.0　m/s,　and　the　blockage-fire　distance　varied　from　0.35　m　to　1.6　m.　The　temperature　and　the　ignition　time　delay　were　measured.　Results　show　that　the　ignition　time　delay　is　shorter　with　shorter　blockage-fire　distance.　The　ignited　vehicle　results　in　the　temperature　hump　and　larger　high　temperature　region　at　downstream.　A　modified　model　to　predict　the　maximum　temperature　beneath　the　tunnel　ceiling　by　considering　the　combined　effect　of　longitudinal　ventilation　and　blockage-fire　distance　is　proposed.　Finally,　the　predictions　obtained　by　proposed　model　are　compared　with　the　experimental　data　and　previous　experiments.
