Abstract(J)	筒内に噴射された燃料噴霧は周囲の空気を取り込みながら発達していく．その過程においては，噴霧側面への空気導入の流れが隣接する噴霧のそれと干渉する．また噴霧はピストン壁と干渉し壁面に沿って発達後，同様に発達した隣接する噴霧とも干渉する．本報では，単気筒エンジンを用いて各干渉が燃焼に及ぼす影響を検証した． Translation
Abstract(E)	Fuel spray injected into diesel engine cylinder develops with entraining ambient air. Air entrainment flow surrounding the spray side boundary interferes with that of adjacent sprays. And the spray interferes with piston wall and develops along the wall surface. Then the spray interferes with the adjacent sprays developing along the wall surface similarly. In this study, the effect of each interference on combustion was investigated by using a single cylinder engine.

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".
