Abstract(E)	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.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.
