Poll: Next big "green" powertrain
What will be the next big "green" powertrain in the U.S.?
BAF Technologies Starts Converting AT&T Vehicles to CNG
BAF Technologies said that it has started converting 600 AT&T Ford E-Series vans to CNG technology in 2009.AT&T expects to spend an estimated $350 million to purchase about 8,000 CNG vehicles as part of a $565 million, long-term strategy to deploy more than 15,000 alternative-fuel vehicles over the next 10 years. AT&T's investment represents the largest U.S. corporate commitment to CNG vehicles to date. The new deployments will bring AT&T's alternative-fuel fleet to more than 15,000 vehicles by 2019.
The vehicles will utilize the BAF CapComp System, a proprietary CNG fuel system certified by the EPA. CNG vehicles are expected to emit approximately 25 percent less greenhouse gas emissions than those traditionally powered by gasoline.
The CapCom System is fully integrated into the OEM powertrain control system. No additional control module is required.
The entire gasoline system is removed and replaced with CNG storage tank(s), HP plumbing, a CNG regulator, and new CNG injectors.
Control of all CNG components, including the original dash-mounted fuel gauge, is done using the OEM vehicle computer which BAF reprograms to optimize CNG performance. In a CNG Ford E-350 Van, the BAF CalComp system is integrated with the 5.4L V8 Triton engine.
The CalComp system features Include:
- Closed-loop fuel control
- Sequential fuel injection (SFI)
- Optimized ignition timing
- Maintains original fault codes (DTCs)
- Diagnostics accessed through DLC using original scan tool or any generic OBD-II scanner
AT&T will work with natural gas service providers to build up to 40 new CNG fueling stations across its operating region to provide the fueling infrastructure needed for the new vehicles.
The new CNG/passenger vehicle commitment follows AT&T's deployment of 105 alternative-fuel vehicles in more than 30 U.S. cities beginning in June 2008. In addition, AT&T piloted four Ford Escape hybrids, which were deployed in late 2007 in California.
