Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

First hydrogen combustion engines will most likely go into series with port-fuel injection, based on Diesel engine hardware. But it is already obvious that direct injection concepts will represent the second generation of mixture formation systems. Challenges like injection nozzle design and mixture formation for highest levels of homogeneity are already well known. Market participants are improving these kind of product properties.
This paper discusses several additional opportunities aiming to increase the homogeneity index of direct injection concepts allowing in consequence lower NOX and/or higher torque output at the borderline of an air-to-fuel ratio of approximately 2.5.
The new Schaeffler Dual Mode nozzle provides first results in terms of homogeneity using both flow patterns, Coandă and a straight jet, during the same engine working cycle. The Coandă fuel mass share can be varied by parameters like pressure ratios, needle lift and Coandă radius leading to a current reduction of engine out NOX Emissions of 30–40%.
