Technical expertise on the cause of engine failure of the Mitsubishi Pajero Sport
Journal Title: Invention Journal of Research Technology in Engineering & Management - Year 2018, Vol 2, Issue 5
Abstract
The article concerns the case of the damage to the Mitsubishi Pajero Sport engine and the methodology a technical expert applied to identify a direct cause of failure. The engine failure occurred while a vehicle was being repaired to eliminate air conditioning malfunction and engine overheating. When repairing, it was necessary to replace a cylinder head and the pistons were checked removing the pully from a crank shaft. After the repair had been completed and after 16-day vehicle operation, engine timing belts got damaged. To eliminate this malfunction, damaged belts were replaced. Thirty (30) days after the vehicle had been put into operation, emergency engine failure occurred, and a technical expert was called upon to assess the quality of the repairs having been performed. The article describes the procedures and methodology a technical expert applied. In the conclusion, the findings are stated. To determine the cause, a vehicle was on the car service station premises, where a technical expert was present and according to his instructions, diagnostic and subsequent disassembly works have been done. The procedure of evaluating the key characteristics on individual parts, their display, and the resulting evaluation are described.
