Abstract(J)	エンジン排出ガス中の成分について、FTIRで直接計測できない水素と酸素濃度の推定法を検討した。水素、酸素各々について、FTIRで計測可能な成分との相関関係から回帰する方法と、赤外吸収スペクトルを用いて推定する方法を、ガソリンエンジンアウトの排気で評価した。定常および過渡運転において本方法の有効性を確認した。 Translation
Abstract(E)	Quantitative estimation methods of hydrogen and oxygen concentrations in gasoline engine exhaust gas are studied. About hydrogen, oxygen each, two kinds of method are evaluated. One is a method to recur from the correlation with the measurable gas components in FTIR analysis and the other is one using the infrared absorption spectrum. These are compared and validated in gasoline engine out exhaust gas emissions both at steady-state and transient operations.

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".
