Reducing Lawnmower Exhaust Emissions in the U.S. Postal Service 961734
An electronic fuel/air mixture controller has been developed which is designed to reduce exhaust emissions on small utility engines. Lean Power Corporation has conducted a field study using this controller in cooperation with the United States Postal Service. Additional laboratory testing was performed in cooperation with the U.S. Environmental Protection Agency using the SAE J1088 test procedure.
In this study, electronic air/fuel mixture controllers were installed and exhaust emissions evaluated on a sample of lawnmowers and engines. A significant reduction was achieved in Carbon Monoxide and the sum of Hydrocarbons plus Oxides of Nitrogen with the electronic mixture controller.
