发动机排气系统产生的热量比大多数人意识到的要高得多。借助发动机上的所有重要组件，重要的是要对热量进行适当的保护。在保护发动机的重要部位免受火灾时，隔热罩是第一道防线。这种类型的盾牌通常由金属或陶瓷材料制成。隔热罩在整个发动机室中均安装，并执行非常具体的工作。每次运行发动机时，隔热罩都必须提供保护。

安装在汽车上的隔热罩应该像汽车一样持续。与其他任何金属组件一样，Rust是汽车上的隔热罩将拥有的最大敌人之一。由于发动机产生的水分，最终将开始显示生锈的迹象。没有解决盾牌所带来的生锈问题会导致各种不同的问题。如果发动机的某些部位太热，则可能导致火灾危害和其他危险情况。

The more you are able to find out about the overall condition of this part, the easier you will find it to get the proper repairs when needed. Due to the importance that this part plays in the running of the engine, it is important to get a professional to perform the repairs that are needed. The following are some of the things that you may notice when your heat shield is in need of replacement:

Getting the heat shield replaced in a hurry is wise due to the damage that it can cause. If you have any concerns about your car overheating, or are already experiencing increased heat in your car, it may be good time to检查或更换隔热罩。
