NOTE: Data are continuous NDIR except Reactivity Units which are from F.I.D. tests on bag samples. 1/ Gasoline emissions are for cold start sequence, except as noted in 2/ Natural gas emissions are from hot start cycles, corrected to 11% difference between cold and hot starts, Table I. 3/ Reactivity Units for natural gas from Table IV. 4/ Hot start cycles. footnote 4/, corrected to 15% CO2. 5/ Oxides of nitrogen derived from bag samples, using mean ratio of bag to NDIR values. |
