California and federal officials have approved the Longview diesel emission retrofit system for use in all 50 states on virtually all on-road heavy-duty diesel engines
manufactured between 1994 and 2002, officials of Cleaire Advanced Emission Controls, announced this week.
"This technology can now be used to reduce emissions from buses and trucks across the country," said Brad Edgar, executive vice-president and chief technology officer for Cleaire, which is based in San Leandro, Calif. Clearaire's retrofit technology replaces the muffler in the exhaust system of a diesel vehicle, where it operates much like a catalytic converter in an automobile.
The federal approval is the result of a reciprocity agreement by which the federal Environmental Protection Agency will accept verifications from the California Air Resources Board.
The Longview reduces both particulate matter (PM), commonly referred to as soot, and oxides of nitrogen (NOx), a prime contributor to smog.
The verification classifies the Longview at 85% reduction in PM (the highest level possible) and a 25% reduction in NOx.
Cleaire Advanced Emission Controls (www.Cleaire.com) develops and manufactures retrofit systems that reduce emissions from diesel engines. Cleaire products are distributed through the Cummins distribution network.
