Clean Air Partners (CAP, San Diego, CA) demonstrated ultra-low emissions on its C-12 dual-fuel truck engine through a project sponsored by the National Renewable Energy Laboratory (NREL, Washington, DC). With NOx levels of only 0.5g/bhp-h and particulate matter measuring 0.004g/bhp-h, the system has established new benchmarks for CAP’s ultra-low emission technology.
"This project is part of Phase I of the Next-Generation Natural Gas Vehicles Program, led by the US Department of Energy (Washington, DC) and NREL, to develop advanced, commercially viable, medium- and heavy-duty, natural-gas vehicles," explained HC Wong, chief engineer at CAP and the program manager of the project. "By 2004, this can enable a commercially practical vehicle powered by an engine with NOx emissions of 0.2g/bhp-h or lower that meet the 2007 EPA emission regulations."
