Recommended practice for determining exhaust emissions from heavy-duty vehicles under transient conditions. Technical report

Technical Report ·
OSTI ID:6647806
This recommended practice represents the completion of one phase of EPA's transient cycle development effort. The finalized chassis procedures detailed here parallel the engine test procedures recently published as subpart N of the Heavy-Duty Notice of Proposed Rulemaking (NPRM). The engine test will remain for EPA the primary means of determining transient heavy-duty emissions; however, the chassis test will be available when total-vehicle testing is desired (for example, for a radically new engine design, for in-use programs, or perhaps for future durability testing on in-service vehicles). This report contains a bibliography of EPA technical reports and contract reports which document various aspects of the chassis driving cycle and engine cycles' development.
