Peterbilt LNG is first SmartWay alt-fuel

| September 16, 2011

Peterbilt Motors Co. Sept. 16 said it received accreditation for developing the industry’s first SmartWay designated alternative fuel vehicle.

The U.S. Environmental Protection Agency’s SmartWay Program has recognized Peterbilt’s Model 386 liquefied natural gas truck as meeting the established fuel-saving, low-emission equipment requirements set for Class 8 trucks. The Model 386 LNG will join Peterbilt’s other SmartWay designated vehicles, which are models 587, 386 and 384.

Equipped with a fuel efficient, aerodynamic package, the Model 386 LNG SmartWay designated vehicle is ideally suited for a variety of applications, including line, bulk and tanker hauling.

The contoured aerodynamic package features roof fairings with trim tabs that help propel air up and over the cab and trailer, re-contoured chassis fairings pushing airflow around the tires and wheels, and a Peterbilt transition fairing positioned between the cab and detachable sleeper directing airflow over and around the sleeper. In addition, a composite molded sunvisor featuring a Gurney strip design transitions air more efficiently over the cab while providing glare protection for drivers, and three-inch rubber mounts are fastened to the end of the sleeper driving airflow out and around the trailers.

The alternative fueled vehicle is powered by the EPA-certified Westport GX engine, offering up to 475 horsepower and 1,750 lb.-ft. of torque, Peterbilt said. The 15-liter engine uses high pressure direct injection technology, specialized cryogenic fuel tanks, and associated electronic components to facilitate performance and operation. This technology uses a cleaner-burning fuel than diesel without compromising engine torque, power, fuel economy, or drivability, in addition to reducing greenhouse gas emissions by 25 percent, the company said.

Peterbilt also offers compressed natural gas and LNG power platforms. Also powered by Westport GX engine, the Model 367 is aimed at dump, mixer and construction applications. In addition, models 384, 365 and 320, equipped with the Cummins Westport ISL-G engine, can be spec’d with CNG or LNG offering 320 hp and 1,000 lb.-ft. of torque.
