Ap42 Emission Factors: diesel_engine_4stroke_stationary
EPA AP-42 Fifth Edition air pollutant emission factors for stationary combustion and area sources — uncontrolled emission factors in lb/MMBtu (combustion) or lb/hp-hr (engines) or lb/VMT (roads) for NOx, CO, SO2, PM10, PM2.5, VOC. Covers natural gas boilers (small <100 MMBtu/hr, large wall-fired >100 MMBtu/hr, large tangential >100 MMBtu/hr), diesel engines (4-stroke, 2-stroke stationary), gasoline engines (4-stroke), bituminous coal (pulverized and stoker), No. 2 distillate and No. 6 residual fuel oil, wood combustion boilers, LPG boilers, fugitive dust (construction, unpaved roads, material handling), and painting/coating VOC.
