Abstract(E)Further increase in thermal efficiency of internal combustion engines should be the essential issue even in the future carbon-neutral society. To drastically improve thermal efficiency of diesel engines, the effectiveness of the new heat insulation structure, the optimized target thermodynamic cycle, the combination of extremely-high peak cylinder pressure tolerance and higher compression ratio, and their integration have been numerically and experimentally investigated as the technologies for aiming halved cooling loss and much increased “cycle efficiency” (conversion efficiency of effective heat in the cylinder to indicated work). This paper presents fundamental concept and achieved results for each technology by New ACE.

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".
