Abstract(J)産業用エンジンのカーボンニュートラル実現に向けて量産LPGエンジンをベースに燃料供給系を水素用に換装した水素エンジンを開発した.ターボ過給に加え,異常燃焼の抑制技術やクランクケース内循環システムなどの採用による最小限のシステム変更で,ベースエンジンと同等の出力および超低NOx排出を達成した.

Abstract(E)A hydrogen engine was developed by converting the fuel supply system of a mass-produced LPG engine to accommodate hydrogen, with the goal of achieving carbon neutrality for industrial engines. To address the torque reduction caused by the conversion to a hydrogen engine, turbocharger was added, along with abnormal combustion suppression technologies and hydrogen concentration reduction technologies in the crankcase. Minimal system modifications enabled the achievement of power performance comparable to the base engine as well as low NOx emissions.

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".
