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.
