Based on experimental characterization of the scavenging behavior of a cross-scavenged, piston-aspirated, two-stroke, natural gas engine in phase III of the current project, a computationally inexpensive simple scavenging model was improved in this…
In this work, the details of catalyst poison deposition are studied, and new catalyst restoration methods are explored. Lubrication oil makes its way through the combustion chamber and into the exhaust system, depositing poisons onto the catalyst and…
Volatile organic compounds (VOCs) are defined as non-methane, non-ethane hydrocarbons and have negative environmental effects, especially in the formation of ozone that creates smog. The combination of a gas chromatograph and a flame ionization…
An experimental study was carried out to characterize the scavenging behavior of a cross-scavenged, piston-aspirated, two-stroke, natural gas engine to aid in the development of computationally inexpensive simple scavenging models for onboard engine…
Pre-Combustion Chambers (PCCs) are commonly used in large-bore natural gas engines to improve the repeatability of ignition and the completeness of combustion, particularly when the engine operates near the lean limit. A study of the ignition of the…
Using a laser, as opposed to a conventional (electrical) spark plug, to create combustion initiating spark is potentially advantageous for several reasons: flexibility in choosing and optimizing the spark location, in particular, to move the spark…
The available database on NO emissions from large-bore, gas-fueled internal combustion engines were evaluated. Based on these data the expected performance of various NO control approaches amenable to retrofit on in-use engines was projected.
This report presents the data obtained during recent tests on a Clark HBA-8 compressor unit at Transco Refugio Station 20. The data includes vertical and horizontal distortion of the frame as measured by laser targets attached to the frame
