Abstract(J)NH3はカーボンフリー燃料として有望視されているが、低着火性および燃焼速度の遅さが課題とされており、内燃機関への適用にあたっては軽油燃料との混焼が有効である。本研究では、0.8L単気筒ディーゼルエンジンを用い過給高負荷条件下でのNH3-軽油混合割合ならびに空気過剰率が燃焼および排気特性に与える影響を調査した。

Translation

Abstract(E)NH3 is a promising substitute for fossil fuels, but its low ignitability and low burning speed are issues, hence mixing with diesel oil is effective for applying internal combustion engines. In this study, effects of NH3 mixing ratio and air excess ratio toward combustion and emission characteristics have been investigated in NH3-diesel dual fuel engine under high load condition using the 0.8L single-cylinder diesel engine.

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.
