Abstract: The present study proposed an experimental analysis of the burning pattern in a combustion engine vehicle. Fire investigation is based on the analysis of burning patterns resulting from fire behavior. However, up to now, no experimental work carried out in Brazil has sought to prove the repeatability of fire patterns used to investigate vehicle fire scenes. Therefore, the objectives of this research included causing a fire in a motor vehicle to reproduce the burning patterns, evaluating relevant parameters for data collection, observing the development of burn marks through thermal readings at points related to these predicted marks and, finally, measuring the heat flow to which firefighters are exposed during a vehicle fire. Initially, it was expected that the fire would develop in a way that would provide burn marks related to the area of origin, according to the Manual de Perícia em Incêndios e Explosões: II Conhecimentos Específicos as reported (CBMDF Manual de perícia em incêndios e explosões: conhecimentos específicos Diretoria de Investigação de Incêndio—Corpo de Bombeiros Militar do Distrito Federal Brasília, 2019). However, an unexpected dynamic was observed and, consequently, atypical burning patterns. It was evident that the development of a vehicle fire depends on some parameters that have not yet been considered in the aforementioned manual, such as the geometry of the fire panel and the direction and intensity of the wind.
