Abstract(E)	Small scooters have a large share of the motorcycle market because of their convenience and economy. Therefore, fuel efficiency is an important factor when customers choose products. Urban scooter users frequently use the low to medium speed range. The friction loss of the piston is a large part of the engine loss and affects the fuel consumption. The scooter piston slides horizontally. To improve the fuel consumption of scooters, it is necessary to understand the piston operating environment and improve the lubrication environment. In order to determine the thickness of the oil film required to reduce friction, we investigated the operating environment of the piston sliding horizontally at low and medium speed. As a method to control the oil film thickness, we focused on the shape of the streak. To reduce friction loss in scooters, we improved the lubrication environment of pistons.

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.
