Fault elimination process for commercial vehicles by eliminating of the over heating problem in the buses

This study focuses on the fault elimination method by eliminating the overheating problems in the commercial vehicles. Fault elimination which is the main occupation in all engineering systems is a difficult process and should be handled properly. In order to maintain the operation of engineering products, systems or services and improving quality progressively, fault elimination processes should be done by applying science, psychics, mathematics, and engineering knowledge. In the study, the problems such as bad inside climate which affect the passenger comfort and customer satisfaction, discoloration of exterior engine lids, heat transfer through the floor from the engine compartment into interior without absorption of heat and noise, temperature differences, excessive heat in the engine compartment, excessive heat over the seat rails, insufficient ventilation of the interior air, have been studied according to fault elimination method. The most feasible solutions were discussed and proposed in the study such as air flow optimizing, better insulation of engine compartment, additional air ducts, and waste heat recovery. The study showed that managing the excessive heat properly improves efficiency, decreases cost and improves customer satisfaction.
