Cleaire Advanced Emission Controls on Thursday, June 23, announced that the California Air Resources Board has approved an extension to the LongMile diesel particulate filter verification. Cleaire says the extension means that owners of trucks and buses powered by engines equipped with an OEM diesel oxidation catalyst – such as the family of Caterpillar Acert diesel engines – now can retrofit those engines with its LongMile DPF and makes the LongMile applicable to essentially all model year 1994 through 2006 four-cycle engines.

Cleaire says the LongMile’s low temperature requirement allows for broader engine-duty cycle application and greater flexibility in duty cycle changes without compromising the filter’s ability to regenerate. According to the company, LongMile’s greater ash capacity means more time between filter de-ashing, translating into greater operating flexibility, less downtime for maintenance and lower cost of ownership.

“While only introduced in late 2010, customer demand for LongMile’s many advantages has made it our best-selling product,” says Gale Plummer, Cleaire chief executive officer. “We’re pleased that CARB’s extension allows for an even broader range of engines to be retrofit with the LongMile.”

The LongMile, manufactured by Cleaire Advanced Emission Controls in San Diego, is a Level 3+ CARB-verified emissions control device used to reduce particulate matter in diesel exhaust. The LongMile DPF uses a sintered metal material designed to provide low backpressure, high ash holding capacity and low exhaust temperature requirements. Cleaire says the LongMile’s passive regeneration system, compact size and monitoring system make it suitable for retrofitting a broad variety of truck and bus applications.
