Abstract(J)	ガソリンHCCIエンジンの過渡制御MBDのため，MILSプラントモデルに適用するHCCI燃焼モデルを開発した．単気筒エンジン実験と数値解析から，HCCIの燃焼期間が筒内の温度差に由来する着火遅れ差で説明できることを明らかにし，壁面低温部の温度履歴から燃焼終了を特定するため3領域モデルの構成とした． Translation
Abstract(E)	HCCI combustion model has been constructed for development of switching strategy from SI to HCCI. An engine test indicated the differences of heat release between steady and transient on HCCI operation. It analyzed with CFD and chemical kinetics calculation that the change of heat release derives from the wall heat transfer. In-cylinder space is divided into three zones so that the combustion end timing might be characterized from a state transition in a low temperature region near the chamber wall.

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".
