Certification Guidance for Engines Regulated Under: 40 CFR Part 86 (On-Highway Heavy-Duty Engines) and 40 CFR Part 89 (Nonroad CI Engines)

摘要

Under the authority of the Clean Air Act and Federal regulations, manufacturers regulated under these parts must submit applications to obtain a certificate of conformity to EPA. This document describes suggested procedures and formats for compiling such applications. This guidance is applicable to engines regulated by the Code of Federal Regulations, Title 40, Parts 86 and 89 (40 CFR 86 and 40 CFR 89) and in NO WAY supersedes either Part. Examples of engines covered under this document (jointly referred to as Nonroad Engines) are heavy duty diesel-cycle and gasoline-cycle engines for on-highway use, and nonroad compression ignition engines. This guidance also covers evaporative certification for vehicles containing engines which were certified under heavy duty engine protocol. Marine engines at or above 37 kilowatts are regulated under 40 CFR Part 91 and are not included in this guidance.
