Abstract
The effects of engine operating parameters on the speciated engine-out hydrocarbon emissions from a natural gas fueled spark ignition 16 valve four-cylinder engine were examined. Total hydrocarbon emissions were dominated by methane, the main component of natural gas. The non-methane hydrocarbons consisted primarily of ethane, ethene, and acetylene. Except for changes in the fuel-air equivalence ratio rich of the stoichiometric condition, emissions of unsaturated species were found to be less sensitive to engine operating parameters than were the fuel components. A single species, ethene, dominated the engine-out hydrocarbon reactivity, accounting for over 80% of the NMHC reactivity.
