Abstract(E)	Inversed-delta injection concept and TAIZAC (TAndem Injectors Zapping ACtivation) injector developed by the authors through SIP Innovative Combustion Technology Program (October 2014 to March 2019) and AICE Project Research (April 2019 to March 2021) for thermal efficiency improvement of diesel engines are briefly reviewed. Optical diagnostics of diesel late combustion, conceptual proposal for late combustion reduction based on the inversed-delta injection rate shaping, development of TAIZAC injector as a handy and effective research tool to realize the injection rate shaping, demonstration of engine thermal efficiency improvement, and further experimental examination of vortex development, enhanced mixing and heat release are outlined.

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".
