Emissions testing and modeling ensures that propane-fueled engines and vehicles meet current regulations and take full advantage of propane's clean-burning characteristics.
Emissions testing and modeling assesses and models emissions of vehicles and engines (school and transit busses, heavy-duty trucks, etc.) that burn propane fuel. Projects also include emissions certification of propane-fueled engines and vehicles.
Projects
Greenhouse Gas (GHG) Emission Factors for MOBILE6.3/MOVES Model (Docket 11323)
Compilation of data about the three key GHGs — methane (CH4), nitrous dioxide (N2O), and carbon dioxide (CO2) — emitted by propane trucks for the EPA OTAQ for inclusion in its MOVES model.
Model Year 2003 Propane Gas Vehicle Emission Factor Derivation for MOBILE6.3/MOVES Model (Docket 11123)
Compilation of propane gas vehicle emission factor profiles for use in EPA MOBILE6.3/MOVES model. Focus on OEM propane gas light-duty pick-up trucks, heavy-duty trucks, school bus, and transit bus applications.
LPG Emissions Deterioration Factor Project (Docket 10319)
Development of propane-specific deterioration factors for engines for EPA publication CD-95-14. Includes defining factors for at least 15 light-duty engine families based on actual emissions testing.
Integrating Propane into EPA's Mobile Model (Docket 10266)
Negotiation with EPA about incorporating propane vehicle emission values into the MOBILE model. Presentation of technical data to EPA.
