Peterbilt Motors Co. announced the availability of the next generation of PACCAR engines, which the company said has been developed to meet the Environmental Protection Agency’s (EPA) 2013 emissions requirements. The PACCAR MX-13, PACCAR PX-9 and PACCAR PX-7 engines are designed to maximize fuel efficiency and reliability, and provide a low total cost of ownership, the company added. The PACCAR engine lineup will be available in Peterbilt’s complete range of medium- and heavy-duty products beginning in 2013.
“The integration of PACCAR engines into Peterbilt vehicles provides an outstanding solution to our customer’s operational needs,” said Bill Kozek, Peterbilt general manager and PACCAR vice president. “The new PACCAR engines were developed to combine increased fuel economy with industry leading reliability, resulting in maximum operating efficiency.”
The 12.9-liter PACCAR MX-13 engine is characterized by its combination of proven technologies and a large number of state-of-the-art innovations that improve fuel economy, the company said. It is designed to meet the demands of heavy-duty truck applications in both vocational trucks and on-highway tractors and is available in a wide range of horsepower ratings starting at 380 with torque offerings up to 1,450 lbs.
Additional PACCAR MX-13 engine enhancements include a common rail fuel system that maintains injection pressures of 2,500 bar, providing improved efficiency. The result is finer fuel atomization and more ways to optimize combustion, ensuring the lowest possible fuel consumption, emission and noise levels, the company said.
The PACCAR MX-13 is available in Peterbilt’s all-new Model 579, as well as the company’s Models 587, 386, 384, 389, 388, 367 and 365.
The 8.9-liter PACCAR PX-9 engine has one of the highest power-to-weight ratios in its class, with heavy-duty features like replaceable wet liners, roller cam followers, bypass oil filtration and targeted piston cooling, Peterbilt said. It is available in both medium- and heavy-duty configurations with horsepower ratings from 260 to 380 and provides up to 1,250 ft.-lb. of torque. The PX-9 is available in Peterbilt’s regional haul Model 382, specialty application market Model 348, and the Model 320, a low cab forward vehicle specializing in refuse markets.
The 6.7-liter PACCAR PX-7 engine delivers superior performance, minimizes operational costs and maximizes uptime for medium-duty customers, the company said. It is available in horsepower ratings from 200 to 325 and offers up to 750 ft.-lb. of torque. The PX-7 is available in Peterbilt’s entire medium-duty product line, including Models 330, 325, and Models 210/220, which are ideal for pickup and delivery, towing, refrigerated van, roll-off and landscaping applications, the truck maker said.
