Translation

Abstract(E)The purpose of this study was to investigate the dilution ratio of oil by fuel in each part of the piston and the oil tank due to the difference in post injection timing, and to clarify the transportation route of the fuel adhering by post injection from the cylinder wall to the oil tank. Under motoring conditions, the maximum dilution was shown in the oil tank and top ring groove when the post injection timing was 60 °. The dilution ratios of the 2nd land part and the 2nd ring part showed the same tendency at any post-injection timing. In addition, there was no significant change in the dilution rate even if the position of the ring gap was changed.

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.
