| 中文摘要: |
| 本文使用二氧化碳灭火系统进行了汽车发动机舱火灾灭火试验,试验表明:系统采用闭式洒水喷头自动启动时,在风的作用下,火羽向风的下游偏移,可能导致下游的喷头启动,不能有效灭火。系统手动启动时,在发动机舱内部安装4个或者8个开式喷头,均能迅速扑灭汽车发动机舱火灾,且具有灭火时间短,灭火剂用量少,灭火效果好的特点。 |
| 英文摘要: |
| Experiments were performed to study the suppression of automobile under-hood fires by carbon dioxide extinguishing system.The results show that if the automatic sprinklers are used to inject carbon dioxide,the system can’t effectively extinguish fires under effect of strong wind;however,if open sprinklers are used and operated manually,the system comprising of 4 or 8 sprinklers is capable of extinguishing fires rapidly with a small amount of carbon dioxide. |
