Current wisdom acknowledges that emissions from an engine used in over-the-road vehicles should employ a test incorporating transient engine speeds and load. It is well documented that a sudden increase in engine load is characterized by an increase in hydrocarbon emissions. The objective of this paper is to present a method for developing a chassis test for a specific and typical class of vehicles which will mirror the Federal Test Procedure (FTP) as closely as possible for purposes of emissions measurement. Emphasis will be placed on development of a preliminary heavy-duty chassis cycle for specific over-the-road class 8 trucks which will reflect the FTP currently imposed on heavy duty diesel engines.
