Kenworth trucks to use PACCAR motors

Kenworth is enhancing its engine line-up for 2013 with the addition of the next generation of PACCAR proprietary engines


Kenworth is enhancing its engine line-up for 2013 with the addition of the next generation of PACCAR proprietary engines, which are designed to deliver industry-leading performance, reliability and fuel efficiency.

Kenworth customers can now specify the new PACCAR MX-13, PACCAR PX-9 and PACCAR PX-7 engines on new Kenworth truck orders placed through Kenworth dealers in the United States and Canada for delivery in 2013.

"The new engine line-up further strengthens Kenworth's vertical integration," said Judy McTigue, Kenworth director of marketing planning and research. "PACCAR's latest engine technology provides efficient and productive performance for customers in a wide range of truck applications."

 

PACCAR MX-13

The 12.9-liter PACCAR MX-13 engine is designed to meet the demands of heavy duty truck applications. The engine is available for Kenworth Class 8 models, including the Kenworth T660, T680, T700, T800 and W900. 

"The new PACCAR MX-13 engine offers a wide range of horsepower and torque ratings to meet customer power requirements. This engine opens the Kenworth door to additional customers in vocational applications, including logging, dumps and hauling applications over 100,000 lbs.," said McTigue. The engine's horsepower and torque begin at 380 hp and 1,450 lb-ft, respectively.

The PACCAR MX-13 utilizes the latest common rail, fuel-delivery technology, which enables injection pressures of up to 2,500 bar and significantly enhances fuel efficiency and performance.

The common rail fuel system uses controls to regulate the fuel in a central manifold, only compressing the amount of fuel mixture needed. The result is finer fuel atomization and more ways to optimize combustion, ensuring the lowest possible fuel consumption, emission and noise levels.

 

PACCAR PX-9

The 8.9-liter PACCAR PX-9 engine is available for Kenworth medium and heavy duty trucks, including the Kenworth T270, T370, T440, T470 and W900S. The PX-9 possesses one of the highest power-to-weight ratios in its class, with heavy-duty features such as replaceable wet liners, roller cam followers, bypass oil filtration and targeted piston-cooling. 

The PACCAR PX-9 offers ratings from 260 to 380 hp and provides up to 1,250 lb-ft of torque. The engine delivers the durability and efficiency necessary to help lower operating expenses, reduce maintenance and increase productivity. 

 

PACCAR PX-7

The 6.7-liter PACCAR PX-7 engine is available for Kenworth's medium duty conventional and cabover line-up. The engine offers ratings of 200 to 325-hp and up to 750 lb-ft of torque for the Kenworth T170, T270 and T370.  For the Kenworth K270 and K370 cabovers, PACCAR PX-7 ratings are 220-hp /520 lb-ft, 240-hp/560 lb-ft and 250-hp/660 lb-ft. 

The PACCAR PX-7 delivers superior performance, minimizes operational costs and maximizes uptime for medium duty customers.

The PACCAR MX-13, PACCAR PX-9 and PACCAR PX-7 replace the PACCAR MX, PACCAR PX-8 and PACCAR PX-6, respectively. The new engines are undergoing extensive testing and dealer service technicians will receive engine training to help provide excellent customer support.
