The emissions should be displayed in ppm.The following notes apply to Illustration 9.
12 - Emission data is post Caterpillar provided catalyst, values are dependent on proper engine and catalyst maintenance.
13 - NOx values are the maximum values expected under steady state conditions.
14 - CO, CO2, THC, NMHC, NMNEHC, and HCHO values are "Not to Exceed" levels. THC, NMHC, and NMNEHC do not include aldehydes.
15 - Volatile Organic Compounds (VOCs) as defined in US EPA 40 CFR 60, subpart JJJJ.
16 - Exhaust Oxygen tolerance is 0.2, Lambda tolerance is 0.05.Ratings that include a Caterpillar supplied catalyst (integrated catalyst) will show emissions after the catalyst that should represent Not to Exceed (NTE) values over the life span of the catalyst. To see engine out (pre catalyst emissions) look for a "sister rating" that is labeled as "catalyst setting".
