| 抄録(英) | This study analyzes the causes of diesel injector claims in the Indian market from the perspective of the low-pressure fuel system and fuel characteristics under low-temperature conditions. Injector claim rates exceed 1%, predominantly occurring in northern regions with harsh winters. Investigations reveal that fuel filter internal leakage caused by paraffin crystallization and structural weaknesses leads to injector malfunction. Comparative chamber tests confirmed filter leakage in specific filter types under cold conditions. Field tests in mountainous northern India supported these findings. Recommendations include structural improvements and heater application to mitigate leakage. This research contributes to enhancing diesel injector reliability in challenging climates. 翻訳 |
