Abstract(J)IDI燃焼エンジン向けに特化した新電子制御燃料噴射システムを備えるD902-Kエンジンを開発した。噴射特性の違いに注目した副室・インジェクタ仕様の最適化により、5%以上の燃費改善と可視スモークレスを同時に実現した。またクランクケース冷却水路を変更し、現行機以上の耐久性を確保した。

Abstract(E)We developed the D902-K engine with a new electronic control fuel injection system specialized for IDI combustion diesel engines. By optimizing the characteristics of the sub chamber and the injection system, we achieved over 5% improvement in fuel efficiency and simultaneously achieved invisible smoke emission. Additionally, the crankcase coolant passage was modified to ensure higher durability than current models.

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.
