Shahai Sharpening SwordEscort with ingenuity--The Story of Fukuda Maintenance Engineer's Difficult Work in United Arab Emirates
I, Sima Aiming, Wang Jiming, Wu Jianhong and other masters, will go to United Arab Emirates in November 2025 to provide guidance on passenger car maintenance
The Foton bus project we undertook in the United Arab Emirates has caused problems such as power system failures and poor contact of circuit interfaces on many buses due to extreme local conditions of high temperatures and high sand. The goal is to quickly investigate and resolve vehicle failures and restore normal operation of all vehicles; Optimize vehicle sealing and cooling systems to improve vehicle adaptability under local working conditions; and simultaneously complete customer technical training to ensure stable use of subsequent vehicles
After the maintenance team arrived at the scene, it immediately carried out comprehensive troubleshooting. Combined with the vehicle operation log and customer feedback, the main fault types and causes were determined as follows: Power system failureEngine power is low and accidental flameoutSand and dust block the air filter and fuel filter element, resulting in poor air intake and fuel supply; overload of the engine cooling system in high temperature environmentsCircuit fault, flashing light, abnormal instrument displaySand and dust invade the circuit interface, causing contact oxidation and poor contact; high temperature causes the aging of some line insulation layersAging seals sand seepage at door and window sealsThe large temperature difference between day and night in the local area accelerates the aging of seal rubber materials and reduces sealing performance.
Overseas maintenance under extreme working conditions requires targeted preparations in advance, including customized parts, special maintenance plans and high temperature protective equipment. Overseas services need to strengthen the ability to localize spare parts allocation, establish an Incident Response Service mechanism, and effectively shorten the fault handling cycle. The simultaneous advancement of technical training and maintenance services can significantly improve customers 'independent operation and maintenance capabilities and reduce the incidence of subsequent failures.
