Abstract

Engine compartment forms often a geometrical complex and is filled with a variety of combustible materials. In this paper, two groups of half scale fire experiments were conducted to investigate the fire behavior in the engine compartment of a motorcoach under different conditions. In the first experiment group, the obstacles made of iron boxes and pipes, arranged accordingly to the actual structure of a motorcoach engine compartment, were placed inner the experimental apparatus and a liner type fire source was adopted. In the second experimental group, the pool fire was used and the horizontal wind underneath the apparatus was added. Measurements of interior temperatures with different diameter thermocouples were performed. Standard video and static photograph were recorded. The temperature measured in the experiments was compensated by the first order method. Results showed that the pool fire and wick-type oil-burning formed both on the obstacles' surface and ground greatly prolonged the burning time. The horizontal wind underneath the engine compartment remarkably enlarged the flame size and changed its shape. We recommend that oil leakage to the equipment surface and using thermoplastic materials in engine compartment should be avoided. In the case of fire the motorcoach engine should be turned off immediately.
