Abstract:

This report describes the results of research that was conducted to evaluate designs of the partition between the engine compartment and the passenger compartment in motorcoaches (rear-mounted engines), medium-size buses (forward-mounted engines), and school buses. The research examined the following. The ability of the partitions to mitigate the propagation of fire originating in the engine compartment into the passenger compartment. An accounting of openings or gaps in partition designs that could allow fires to propagate and noxious gases to flow into the passenger compartment. Conformity of firewall designs to identify benchmarks in terms of their ability to mitigate propagation of engine fires into passenger compartments. Practical considerations and design constraints for improved partitions to mitigate propagation of engine compartment fires into the passenger compartments.
