Abstract(J)ゼロエミッションの実現に向けて内燃機関からのCO2とNOx排出の同時低減が求められている.本研究では,リーン燃焼排気(二気筒分)の100% EGRによる希釈ストイキ燃焼(二気筒分)を用いてTWC適用可能な二段燃焼式水素エンジンシステムをシミュレーションにより提案した.その結果を基に四気筒ディーゼルエンジンをベースとした実機構築を含めて検討した.

Translation

Abstract(E)To realize zero emissions, simultaneous reduction of CO2 and NOx emissions from internal combustion engines is required. In this study, a two-stage hydrogen engine system enabling the application of a TWC was proposed through simulations using diluted stoichiometric combustion with 100% EGR of lean-combustion exhaust gas. Based on the simulation results, a prototype engine based on a four-cylinder diesel engine was developed for further investigation.

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.
