Baytech Announces 6.0L CNG Engine and Vehicle Certifications

LOS ALTOS, Calif.--Baytech Corporation has received 2006 and 2007 EPA and CARB certifications for Baytech’s compressed natural gas (CNG) fueled GM 6.0L heavy duty engines, and medium and light duty vehicles equipped with the GM 6.0L engine. Heavy-duty engines are available in both dedicated CNG and bi-fuel (CNG or gasoline) configurations in all 50 states. Dedicated CNG medium and light duty vehicles are available in all 50 states and are certified SULEV; bi-fuel is available only in states that do not require CARB standards.

As part of the certification process, Baytech successfully achieved OBDII compliance approval from CARB for the medium and light duty 6.0L CNG vehicles. OBDII approval work was jointly funded by the South Coast AQMD, with additional support provided by Clean Energy.

The Baytech heavy duty CNG 6.0L engines are certified for use in the GM Topkick/Kodiak C Series and W4500, Isuzu NPR HD, GM Express/Savana Van Cutaway, and Workhorse heavy-duty vehicles with Gross Vehicle Weight Ratings ranging from 14,000 lb to 37,600 lb. Heavy duty engine emissions testing was funded in part by the Texas Commission on Environmental Quality.

Medium and light duty CNG vehicles certified by Baytech include the GM W3500, Isuzu NPR, Workhorse chassis, GM Silverado/Sierra 2500HD/3500 Classic pickup trucks and Chassis Cab, and GM Express/Savana Full-Size Van and Van Cutaway. All dedicated CNG medium and light duty vehicles are certified SULEV.

“Baytech has significantly expanded the line-up of CNG vehicle models we can offer to our fleet customers to include both 6.0L and 8.1L vehicles and engines,” says Richard Turner, Baytech Vice President. “The response has been fantastic.”

The CNG fueling systems incorporate Baytech’s sequential Multi-Port Fuel Injection technology for gaseous fuels. Baytech’s engine calibration software provides optimized closed-loop fuel control, spark advance and other engine parameters. Engine diagnostics functions are accessed through the vehicle’s diagnostic port with the same scanners used for gasoline diagnostics.
