Abstract(E)	Production GDI injectors have been modified for use as high speed sampling valves. Data is presented showing how, when used with existing high frequency response emissions analysis equipment, cyclic measurements of hydrocarbons (indicated AFR) and CO₂ (indicated trapped residuals) can be made with rather easily. It is shown that the high speed sampling valve concept (which we dub the CSV) is adequately rugged, and can be used for extended periods. The CSV employs a unique sampling method, which eliminates pressure interference in the gas sensor unit.

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.
