1991 Mitsubishi Eclipse: Case Study

Summary of Fire Investigation

 

Propagation

  • Fuel: Engine oil
  • Ignition: Hot surface likely, mechanical spark possible
  • Initiation: Immediate
  • Propagation time: Fire extinguished before propagation to passenger compartment


The oil pan was breached by collision with the culvert after the vehicle left the road. Engine oil was splattered directly on the hot exhaust system adjacent to the oil pan. Oil collection occurred in the mesh covering around the exhaust pipe and was likely ignited by the hot surface. Propagation of fire was minimal because of its location (high on the upside down vehicle) and because it was extinguished rapidly.
