Abstract(E)	This study presents the impact of two engine oil additives on fuel efficiency and CO₂ emissions. Formulations containing either Olefin Copolymer (OCP) or Comb polymer (Comb) were compared in tests for fuel efficiency retention, fine particle emissions, and ash accumulation in the gasoline particulate filter. The Comb formulations showed higher fuel efficiency throughout the testing, retaining this efficiency after three distinct engine aging test cycles. No significant differences between formulations were observed in oil consumption, ash accumulation, and filtration efficiency.

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.
