Production to begin on new engine series

Paccar’s MX engines have CGI heads and blocks.

Paccar will begin building its MX Series of engines this summer at a $400 million factory in Columbus, Miss. The engines will be standard on Peterbilt and Kenworth trucks, which are produced by Paccar. The MX was developed by Paccar’s European subsidiary DAF and was an early recipient of selective catalytic reduction emissions technology. The series features an in-line, six-cylinder design with four valves per cylinder. Five engines make up the MX Series, with power ratings ranging from 380 to 485 horsepower and 1,450 to 1,750 lb.-ft. of torque. The MX engines are designed with compacted graphite iron heads and blocks. Paccar is the only heavy-duty engine maker to construct both components from this lighter, yet stronger material. CGI gives MX engine components 75 percent greater strength and stiffness and a 200 percent increase in thermal fatigue resistance. In addition, CGI is quieter and transmits fewer engine vibrations to the cab of the truck. The MX engines come with a two-year/250,000-mile standard warranty. Each certified Paccar dealer will provide full service support for the new engines.

Seat uses advanced vibration control

The Bose Ride will be produced “on a build-to-order basis for fleets at the end of March,” and after that for owner-operators, said Mike Rosen, a chief engineer.

Bose Corp. introduced a futuristic driver’s seat that senses cab vibrations and neutralizes them with high-speed adjustments to the seat’s suspension. The Bose Ride was unveiled at the Massachusetts headquarters of a company better known for its high-end sound systems.

Packed in to the seat’s base are sensors, a microprocessor, power amplifier, linear electromagnetic actuator and energy storage system. Together, these components reduce “whole body” vibration by 90 percent, the company says. To handle the system’s power needs, engineers reduced the electrical demand by designing the system to be regenerative.

“When you hit a pothole, the unit draws energy to hold you in place,” said Jim Parison, the project’s principal engineer. “But then at the other side of that hole the upward impact does the pushing, and the system instantly becomes a generator and sends the excess energy to a local onboard storage device.” This reduces the constant electrical draw to about 50 watts instead of 3,500.

Bose officials declined to discuss pricing except to say that it will be “well below five figures.” The officials also declined to say which truck seat manufacturer is providing the seat back and bottom.
