Abstract(J)	再生可能エネルギーから生成されるオキシメチレンジメチルエーテル（OME）は，Well-to-WheelのCO₂排出量を削減でき，またC-C結合のない化学構造がすす低減に寄与するとされている．本論文では，単気筒エンジンを用いてOME3-5の燃焼・排出特性が軽油に比べ改善することを示した．併せて実施した数値計算により，すす-NOxのトレードオフが改善する要因の１つを明らかにした． Translation
Abstract(E)	Oxymethylene dimethyl ether (OME) produced from renewable energy is a promising fuel for reducing Well-to-Wheel CO₂ emissions and other pollutants. Especially the Soot-NOx trade-off of diesel engines is dramatically improved by using OME. Recent investigations revealed that the chemical structure of OME without C-C bond reduced soot production. In the present paper, we examined the use of OME3-5 in a single-cylinder diesel engine and proved improved combustion and emission characteristics. Simulation results indicate that the lower flame temperature and lower equivalence ratio due to higher oxygen content realized improved Soot-NOx trade-off.

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.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
