Abstract(J)	アンモニアはCF燃料として注目されており、舶用内燃機関では、軽油との二元燃料方式が有望視されている。しかし、その難燃性とN₂O, NO_X等のエミッションが課題と考えられている。本研究では、これら課題解決のために、アンモニア軽油二元燃料機関に、反応性の高い水素を混合した際の基本的な燃焼・排気特性を調査した。 Translation
Abstract(E)	Ammonia is a promising substitute for fossil fuels. In terms of fuel redundancy, a dual fuel system with diesel oil is expected to be utilized for ammonia fueled ships. However, to utilize ammonia is not realized for practical use in ICE due to its low burning speed and emissions of N₂O and NO_X To overcome these chall enges, a mixing with hydrogen, which has high ignitability and high burning speed, is possibly effective. Therefore, in this study, fundamental combustion characteristics of tri fuel combustion engines, in which a mixture of ammonia and hydrogen is ignited by diesel oil, is investigated.

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".
