Nitrogen Oxides Control Regulations | Ozone Control

Nitrogen Oxides are a family of poisonous, highly reactive gases. These gases form when fuel is burned at high temperatures. NOx pollution is emitted by automobiles, trucks and various non-road vehicles (e.g., construction equipment, boats, etc.) as well as industrial sources such as power plants, industrial boilers, cement kilns, and turbines.

Cleaner Air: Mowing Emissions and Clean Air Alternatives

Older more powerful, less efficient two-cycle engines release 25-30% of their oil and gas unburned into the air. Gas mowers emit hydrocarbons and oxides of nitrogen (the principle ingredients of smog), particulate matter (damaging to the respiratory system), carbon monoxide (a poisonous gas) and carbon dioxide (contributing to global warming).
