Abstract Volume I of the report gives emission results for a spark-ignited, largebore, reciprocating, internal-combustion engine operating both under baseline (normal) conditions, and with combustion modification controls to reduce NOx emissions to levels below the proposed new source performance standard (NSPS) for such engines. Exhaust gas measurements included (in addition to continuous monitoring of criteria gas emissions) total organics in two boiling point ranges, compound category information within these ranges, specific quantitation of semivolatile organic priority pollutants, flue gas concentrations of 73 trace elements, and particulates. Exhaust NOx emissions were reduced almost 50 percent, from a baseline level of 1,260 ng/J (730 to 420 ppm corrected to 15 percent O2 dry) by increasing the operating air /fuel ratio of the engine. Accompanying the reduction was a slight increase in engine efficiency. CO, methane, total hydrocarbon, and total semivolatile organic compound emissions were increased from 10 to 65 percent under low-NOx operation. However, total nonvolatile organic emissions decreased 55 percent. The organic emissions for both tests consisted primarily of aliphatic hydrocarbons with some carboxylic acids, phenols, and low-molecular-weight fused-ring aromatics. POMs were detected in concentrations below 4 micrograms/dscm.
