On-Highway Vehicles Two types of Caterpillar® Emissions Solutions are available for on-highway trucks and buses: oxidation catalysts and particulate filters.   Oxidation Catalysts create a chemical reaction with exhaust gases as they pass through the catalyst material. This reaction coverts a large portion of carbon monoxide, hydrocarbons and other emissions into carbon dioxide and water. Available for diesel and natural gas engines, Cat Oxidation Catalysts come with a 1-year/8,000-hour warranty.   Diesel Particulate Solutions use special filters to reduce particulate matter (PM), carbon monoxide and hydrocarbon emissions. Exhaust backpressure is reduced through passive regeneration, a process that automatically removes particulate buildup. Available only for diesel engines, Cat Diesel Particulate solutions include a diagnostic module for backpressure and exhaust temperature monitoring. The type of solution appropriate for a specific application depends on the configuration of the vehicles’ exhaust systems and the specific emissions targeted by the applicable emissions regulations.   Reduce Emissions. Stay Competitive. Caterpillar Emissions Solutions provides the information, products and services you need to comply with emissions regulations, reduce risk and protect your business for the future.
