Abstract(J)自動車の公開諸元のみに基づき、冷間始動の影響を考慮した燃費を予測する手法を提案する。車種によって異なるエンジンの性能曲線は、典型的なデータを回帰して得たマップを諸元に応じて補正することで推定する。エンジンは走行動力を賄うための理論サイクルによって動作すると仮定し、冷却損失量やその他損失量を推定する。

Abstract(E)The various factors contributing to the heat balance such as the heat loss of the engine and the recovery efficiency by the turbocharger need to be considered properly to predict the fuel efficiency of engine vehicle and HVs. However, the specifications are often classified and that is why the detailed data could not be obtained. In the present study, the estimation method of some parameters including the thermal efficiency of the engine based only on published data and open information. The method assumes a theoretical cycle, which has an equivalent power output to an actual cycle.

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.
