PACCAR Introduces Enhancements to MX-13 and MX-11 Engines
PACCAR is launching exciting new power, torque and fuel efficiency enhancements to its MX-13 and MX-11 engines for North America. The new engines will be available in Kenworth trucks in January 2017. “The PACCAR MX-13 and MX-11 engines are designed to deliver optimum performance, durability, fuel economy, and the lowest total cost of ownership for our customers.” said Landon Sproull, PACCAR vice president.
PACCAR increased the MX-13 engine’s output to 510 hp and 1,850 lb.-ft. of torque and increased the MX-11 engine’s output to 430 hp and 1,650 lb.-ft. of torque. The enhanced PACCAR MX-11 engine also adds a new 335 hp and 1,150 lb.-ft. torque rating in the lower end of the power range. PACCAR’s MX engines deliver peak torque at 900 RPM for the majority of engine ratings, supporting increased performance and driving flexibility.
PACCAR designs MX engines to an industry-leading B10 life of one million miles. This means 90% of the PACCAR MX-13 and MX-11 engines are expected to reach one million miles without the need for a major overhaul. Each PACCAR MX engine also comes standard with factory installed remote diagnostics to deliver proactive customer support. This translates into low cost of ownership and superior uptime for truck owners.
The 2017 PACCAR MX-13 and MX-11 engines include a new single cylinder air compressor, variable displacement oil pump, and variable speed coolant pump providing customers with fuel economy gains over the previous engine design. The latest PACCAR MX-13 and MX-11 engines extend oil and fuel filter change intervals from 60,000 miles to 75,000 miles, a significant cost savings for customers over the life of the vehicle. PACCAR MX-13 and MX-11 engines now utilize a single canister aftertreatment system that reduces weight by 100 lbs., improves serviceability and lengthens service intervals.
PACCAR is one of the leading diesel engine manufacturers in the world with the design, manufacture and production of 1.4 million PACCAR engines globally since 1957. “PACCAR will have 135,000 PACCAR MX engines in operation in North America by year end. Nearly 50 percent of Kenworth trucks delivered to customers in North America this year will be powered by a PACCAR MX engine,” said Sproull. “This strong adoption level is a testament to the outstanding performance, durability, fuel economy and low cost of service delivered by the PACCAR MX-13 and MX-11 engines.”
