Abstract This report addresses the emission deterioration rates for spark-ignition engines used in the final NONROAD2008a model. The specific deterioration inputs used in NONROAD and their basis will be addressed for land-based spark-ignition engines at or below 25 horsepower, land-based spark-ignition engines over 25 horsepower, recreational equipment, and recreational marine spark-ignition engines using gasoline. Deterioration is also addressed for land-based liquid petroleum gas (LPG) and compressed natural gas engines (CNG). Deterioration inputs for compression-ignition (diesel) engines are addressed in the report, Exhaust Emission Factors for Nonroad Engine Modeling - Compression Ignition (NR-009d). Relative to the December 2005 version of this report, this version has been updated to incorporate the deterioration rates corresponding to the Phase 3 exhaust standards in the 2008 final rulemaking affecting small nonroad nonhandheld SI engines and equipment, as well as the 2010 exhaust standards for marine SI engines and vessels. It describes updates to the deterioration rates for nonhandheld Phase 2 engines. It also reflects new technology type names assigned to offroad motorcycles, all-terrain vehicles, and snowmobiles.
