Abstract
Research was done to demonstrate the feasibility of using closed-loop three-way catalyst (TWC) technology in off-road large spark-ignited (LSI) engine applications to meet California State Implementation Plan (SIP) emission reduction goals. Available technology was investigated for applicability to engines in this category. Appropriate test cycles were recommended, and five representative engines were selected and baseline emission tested. Total feasible emission reductions were calculated. The retail price equivalent (RPE) for the recommended emission control technology was determined, and cost-effectiveness was calculated. Emission standards necessary to meet SIP goals were recommended.
