EF&EE

Engine, Fuel, and Emissions Engineering, Inc. (EF&EE) specializes in reciprocating engine emissions and emissions control. We build, sell, and maintain advanced emission-control systems, including Compact SCR technology for gaseous-fueled and diesel engines. SCR, or selective catalytic reduction technology, reduces emissions from diesel, biogas, an... d natural-gas engines. Combined with our Optimin self-tuning technology, the Compact SCR system enables natural gas and biogas engines to meet California's strictest emission standards. Compact SCR systems fitted to the diesel engines of the San Francisco-based ferries Gemini, Pisces, Taurus, and Scorpio reduced their emissions of oxides of nitrogen (NOx) and particulate matter (PM) by 97 percent and 60 percent, respectively, winning Gemini the distinction of being "the most environmentally friendly ferry in the nation." EF&EE conceived and developed the RAVEM portable emissions measurement system for laboratory-grade emission measurements (including PM) under field conditions. We sell custom-built RAVEM systems for laboratory and field use, and use our own RAVEM to perform on-board and on-site emission measurements on engines, ranging from automobiles to container ships. EF&EE was founded in 1990 and incorporated as a California corporation in 1992. The company is privately held and more than 90 percent employee-owned.Read More
