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…
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…
Prepared to assist managers and engineers in the gas pipeline industry with a method of making dispersion estimates of effluent from reciprocating engines used for the transmission of natural gas. It is intended to be used as a first approximation of…
Gas exchange processes in two-stroke internal combustion engines, commonly referred to as scavenging, are responsible for removing the exhaust gases in the combustion chamber and preparing the combustible fuel-oxidizer mixture that undergoes…
In 2010, the U.S. Environmental Protection Agency (EPA) adopted a 1-hour nitrogen dioxide (NO2) National Ambient Air Quality Standard (NAAQS) of 100 parts per billion (ppb) or approximately 188 micrograms per cubic meter (µg/m3) that is considerably…
Phase II of the project has focused on improving the initial analysis performed in the first phase by enhancing the various aspects of predictive combustion for lean burn spark ignition natural gas engines under variable composition fueling. These…
The EPA's Industrial Source Complex (ISC) dispersion model was evaluated to determine its applicability to the gas industry. The ISC model uses meteorological data to estimate air quality impacts from multiple source industrial complexes. General…
A brief summary of NO2/NOx emissions data for reciprocating engines and gas turbines. Includes an Excel spreadsheet with the raw data that corresponds to the information in the report.
