Abstract(J)	近年，内燃機関の高効率化とカーボンニュートラル燃料の活用が求められている．一方，燃焼室内に生成・堆積するデポジットは，異常燃焼などを誘発する要因となることが懸念される．そこで本研究では，カーボンニュートラル燃料を対象とした燃焼室デポジット堆積速度予測モデルの構築を目的とした．本報では，模擬デポジット生成実験結果を活用し，燃料組成がデポジット堆積特性へ及ぼす影響について検討した．さらに，実機試験により得られるデータを活用したモデル化についても検討した． Translation
Abstract(E)	In recent years, improving the efficiency of internal combustion engines and utilizing carbon-neutral fuels have become increasingly important. Meanwhile, deposits formed and accumulated in combustion chambers are a concern because they can induce abnormal combustion phenomena. Therefore, this study aimed to develop a predictive model for combustion chamber deposit growth rates in carbon-neutral fuels. In this report, simulated deposit formation experiments were utilized to investigate the effects of fuel composition on deposit growth characteristics. Furthermore, model development incorporating data obtained from actual engine tests was also examined.

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".
