Emissions Solutions

Caterpillar has the right environmental solutions for your on-highway vehicles. Backed by the reliability and performance of Foley, Inc., these solutions reduce emissions and are tailored to fit a wide range of diesel engines.

  • Oxidation Catalysts create a chemical reaction with exhaust gases as they pass over the catalyst material. This reaction reduces some of the particulate matter and converts a large portion of carbon monoxide, hydrocarbons, and other emissions into carbon dioxide and water.
  • Diesel Particulate Filters use special filters to reduce particulate matter (PM), carbon monoxide, and hydrocarbon emissions. Exhaust backpressure is maintained through passive regeneration, a process that automatically removes particulate buildup.

Cat® Diesel Particulate Filter solutions include a diagnostic module for backpressure, exhaust temperature monitoring, and data logging.

The type of solution appropriate for a specific application depends on the configuration of the vehicle’s exhaust system and the specific emissions targeted by applicable emissions regulations.
