The present invention relates to a vent with louvres or punched holes for allowing airflow between an exterior of a vehicle and an engine bay of the vehicle, wherein the vent has an exterior side and an interior side and is formed from a panel, in which the louvres or the punched holes are located, characterized in that the interior side of the vent is provided with an intumescent coating. The intumescent coating will inhibit the spread of flame from the engine bay to the exterior of the vehicle thus containing the fire for a much longer period. The invention is particularly suitable for buses.

    本发明涉及具有通风缝或冲孔的通风口,用于允许在车辆的外部和车辆的发动机舱之间空气流动,其中通风口具有外侧和内侧并由面板形成,通风缝或冲孔位于面板中,特征在于通风口的内侧设置有膨胀型涂层。膨胀型涂层将抑制火焰从发动机舱传播至车辆外部从而在更长的时间内控制火灾。本发明特别适合于公共汽车。
