This report describes and documents exhaust emission factors and brake specific fuel consumption (BSFC) estimates used for spark ignition (SI) engines in EPAs draft NONROAD2004 emission inventory model. It covers engines powered by gasoline, natural gas and liquefied petroleum gas. Additional EPA reports describe other issues relating to emission factors including NONROAD emission factors for evaporative emissions, crankcase emissions, spillage and other non-exhaust emissions (NR-012b), adjustments to emission rates due to variations in fuel and temperature (NR-001b), speciation of hydrocarbon emissions (NR-002b), and adjustments to emission rates as equipment deteriorates due to time and use (NR-011b). Emission factors for compression ignition (diesel) engines are covered in a separate report (NR-009c).
