EPA NSPS for SI Engines – 40 CFR Subpart JJJJ
CK has performed dozens of emissions testing programs to satisfy the requirements of 40 CFR 60 Subpart JJJJ – New Source Performance Standards for Stationary Spark Ignition (SI) Internal Combustion Engines.
The purpose of these programs is to satisfy the compliance demonstration requirements for Oxides of Nitrogen (NOx), Carbon Monoxide (CO) and Non-Methane Organic Compounds (NMOC) contained in the subpart. The scope of testing for these projects includes the use of EPA reference test Methods 1-4, 7E, 10 and 18/25A contained in 40 CFR 60 Appendix A. Generally, three 60-minute test runs are performed. Pollutant emission rates are reported in units of g/HP-hr and ppmvd @ 15% O2.
