Paccar's newly-named MX-13.
KIRKLAND, Wash. — Paccar has introduced a new line of engines for 2013, which it says opens the door to new applications and provides improved performance.
The company’s 2013 engine line includes the MX-13, PX-9 and PX-7.
“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.”
The 12.9-litre MX-13 can be spec’d in applications over 100,000 lbs, the company announced.
“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 PX-9 boasts one of the highest power-to-weight rations in its class, Paccar claims, and offers heavy-duty features such as replaceable wet liners, roller cam followers, bypass oil filtration and targeted piston cooling. It’s available with 260-380 hp and up to 1,250 lb.-ft. of torque.
The PX-7 has power ratings of 200-325 hp and up to 750 lb.-ft. torque.
These engines replace the Paccar MX, Paccar PX-8 and Paccar PX-6 in the company’s portfolio. They’re currently undergoing field testing and dealer service technicians will soon be trained on the new offerings, Paccar announced.
