Abstract(J)	筒内直噴希薄燃焼ニアゼロエミッション水素エンジンの高圧縮比化によって，大幅な図示熱効率の向上を実現することができた．20:1近傍の圧縮比化でもノッキングの発生は抑えられているが，希薄混合気かつ低負荷条件でも筒内の気柱振動が発生すること，過濃化によってもそのレベルが高くならことなど，その発生のメカニズムが炭化水素系燃料とは異なり，混合気の均質化が難しい水素燃料固有の現象であることを明らかにした． Translation
Abstract(E)	Development of energy resources are being targeted to resolve global warming, atmospheric contamination and fossil resource depletion. Among them, hydrogen, which can be produced from renewable energy and emit any CO₂ by combustion is attracting attentions. In application of hydrogen to IC engines, authors proposed a new combustion concept called PCC (Plume Ignition and Combustion Concept), which significantly reduced NOx emissions during high-load operation and achieved high thermal efficiency through combination of lean-burning with jet optimization. In this study, characteristics of in-cylinder pressure oscillation which became evident by increasing compression ratio to achieve much more improved thermal efficiency are evaluated.

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".
