Abstract(J)	内燃機関の熱効率向上には，熱損失の中でも割合が大きい冷却損失の低減が有効である．本研究では火花点火機関を対象として，冷却損失低減効果を拡大するために，伝熱メカニズムを解析した．特に，火炎面が壁面に近接する時の伝熱の変化を解明するため，急速圧縮装置により現象を単純化することにより解析を行った Translation
Abstract(E)	Highly efficient internal combustion engine is still important powertrain to meet a future carbon neutral society. The cooling loss gives a large impact to improve the thermal efficiency. This paper presents a study of the heat transfer mechanism in the SI engine for reduce the cooling loss. This article is highlighting the effect of wall temperature on local heat flux. To simplify the heat transfer phenomena, the experiment was carried out using rapid compression machine. The results indicate the heat flux increases with higher wall temperature caused by wall-flame interaction

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".
