Abstract(J)排ガス規制が強化される中,エンジンの排ガスに含まれる微粒子状物質(PM)が規制対象の一つとなっている. PMは微粒子フィルターを用いて捕集する.捕集したPMを定期的に除去する必要があり,PM酸化触媒を用いた低温化が望まれている.そこで,本研究では最適なPM酸化触媒担持位置を数値計算を用いて推定した.

Translation

Abstract(E)With the tightening of exhaust gas regulations, particulate matter (PM) in engine exhaust gas has become one of the regulatory targets. PM is trapped using a particulate filter. It is necessary to remove the trapped PM periodically, and it is desirable to use a PM oxidation catalyst at low temperatures. In this study, we estimated the optimum support position of the PM oxidation catalyst by using numerical calculation.

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.
