Abstract(J)	新型1.5Lエンジンの開発において，燃費性能の指標として車載走行の平均熱効率を導入した．本報では，温度昇温特性の改善と，それを考慮した最適なエンジン運転点を発電特化型エンジンの特性を活かした制御により，平均熱効率を向上させた手法について報告する． Translation
Abstract(E)	In developing a brand-new 1.5L engine, average thermal efficiency was introduced during on-vehicle driving as an index of fuel economy. This efficiency was improved through control that leverages characteristics of an electric power generation-dedicated engine to achieve optimal operating points considering an improved warm-up temperature profile.

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".
