New EPA Emission Standards

To meet the new exhaust emission standards, manufacturers will likely employ catalytic converters for the first time in many small engines, along with other new technologies.

Small gas-powered engines such as those used in many mowers and other golf course maintenance equipment are subject to new stricter standards by the EPA.

The new standards, which will go into effect beginning in 2010 and target mainly lawn and turf equipment and marine engines, are expected to substantially reduce the amount of gas fumes, carbon monoxide, hydrocarbons and smog-forming pollutants. The cuts go beyond the 60 percent reduction mandated two years ago. Nonroad gasoline-powered engines will see an additional 35 percent reduction in hydrocarbon emissions. The updated engines also will achieve a 45 percent reduction in fuel evaporative emissions.
