Exhaust Emission Tests of Four Heavy Duty Gasoline Spark-Ignited Engines.

摘要

This report covers the confirmation tests on four heavy duty gasoline engines: a 292CID Chevrolet, a 392CID International Harvester, a 360CID Ford,and a 318CID Chrysler. Test methods,equipment,and instrumentation are described. The exhaust gases generated during the test sequence are sampled continually,and specific component concentrations obtained via nondispersive infrared (NDIR) analysers. The basic exhaust emission test is designed to provide single values for hydrocarbon and carbon monoxide on an engine dynamometer simulating a truck driving pattern in a metropolitan area. Composite emission values obtained are presented.
