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).

Excerpt

The article delves into the critical issue of lube oil ignition (LOI) in medium-speed MTU gas engines, which hinders optimal performance and efficiency. Through extensive research and collaboration between Rolls-Royce Power Systems and the Massachusetts Institute of Technology, the authors identify oil droplets from the Power Cell Unit (PCU) as the primary source of LOI. They employ advanced diagnostic techniques, including optical measurements and CFD simulations, to trace the oil's path to the combustion chamber. The study reveals a strong correlation between LOI and the oil control ring gap, providing valuable insights into mitigating this issue. The findings are validated through high-speed camera studies and engine tests, highlighting the importance of understanding oil transport dynamics for enhancing engine durability and efficiency. The article offers a compelling case for the practical application of these findings in both current and future gas and hydrogen engines, contributing to cleaner energy solutions.
