Abstract(J)水素の普及拡大を目指して小型商用車向けに水素エンジンを開発した.V型6気筒3.5Lガソリン過給エンジンをベースに90%以上の部品を流用し,性能/信頼性を満足した上で熱効率40%を実現,排気はEuro7相当の規制値をクリアした.本講演では水素起因の異常燃焼などの技術的な課題とその対応について報告する.

Translation

Abstract(E)To promote hydrogen adoption, we developed a hydrogen engine for light commercial vehicles. Based on a V6 3.5L turbocharged gasoline engine, over 90% of parts were reused while achieving 40% thermal efficiency and meeting Euro 7 emission standards. This presentation will address technical challenges such as abnormal combustion caused by hydrogen and the solutions implemented.

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.
