New Rules Will Reduce Lawnmower Emissions
The U.S. Environmental Protection Agency (EPA) has announced more stringent rules for non-road gasoline engines under 25 horsepower (19 kW). By 2011, manufacturers must reduce hydrocarbon and nitrogen oxide emissions from the engines by 35%. The engines, used in machines such as lawnmowers and string trimmers, must also show a 45% reduction in fuel evaporative emissions.
The rule also covers larger engines, such as those powering recreational watercraft, which must show a 70% reduction in hydrocarbon and nitrogen oxide emissions, a 20% reduction in carbon monoxide emissions, and a 70% reduction in evaporative emissions by 2010.To meet the regulations, manufacturers are likely to equip the affected engines with catalytic converters, which have been required on automobiles since the 1970s. The California Air Resources Board estimates the cost of a walk-behind mower will increase by 18%.
