GE Sensing & Inspection Technologies, Billerica MA, has introduced ACCUSOLVE advanced diesel particulate filter (DPF) soot sensor that enables reduced emissions and improved efficiency of internal combustion engines and after treatment systems, according to GE Sensing information.

ACCUSOLVE provides real-time soot loading data and is designed to meet the harsh environment and life requirements of on-road, off-road, and industrial heavy-duty diesel applications, according to the company's information.

Leveraging proprietary technology from GE Sensing & Inspection Technologies, the high accuracy soot sensor improves diesel fuel economy and meets the stringent performance requirements of heavy duty and automotive diesel engines.

"As we talked to major vehicle OEMs and diesel engine manufacturers, it became clear that the industry needed an improved sensing solution to better control DPF regeneration," said Tim Dummer, global director of transportation at GE Sensing & Inspection Technologies. "To meet this need, GE and a major equipment manufacturer collaborated to develop, validate, and benchmark this innovative technology."

Meeting the strict particulate matter regulations cost effectively, such as the United States Tier 4 emissions regulation, requires the ability to measure DPF loading with high accuracy. The DPF Soot Sensor utilizes radio frequency technology from GE Sensing & Inspection Technologies to achieve much more accurate measurement of DPF soot loadings compared to conventional differential pressure sensors in the market, the company said.

The ACCUSOLVE DPF Soot Sensor is a breakthrough product enabling optimization and extension of the DPF regeneration cycle and results in improved fuel economy, reduced thermal history, and improved filter life. Along with fuel economy and increased asset productivity, benefits also include extended DPF service intervals and reduced warranty costs, the company said.
