Faster processing speed, new engine ratings among new International products

March 4, 2015

INDIANAPOLIS. Navistar International announced some new features on its Diamond Logic electrical system and provided a quick overview of its Uptime program during a press briefing Wednesday at the NTEA’s Work Truck Show.

Diamond Logic is getting a new body control module that offers six times the processing speed, 16 new inputs, three new data links and meets 500K baud regulatory standards, said David Hillman, general manager-vocational truck line for Navistar.

“It’s faster and it has more power,” he said. “What that means for the body companies is it gives them more flexibility to interface their products with ours.”

Because of the new module, Hillman said several new features will now be available on the company’s vocational truck product line. Those include intelligent start, which provides single ignition activation. The starter motor is disabled the moment the engine starts, which prevents over cranking and overheating to extend starter life.

Also available is programmable real time starting, which allows a single person to program when vehicles should start.

“Timed start allows a fleet manager to set the time to start all the trucks so when the drivers come in they are all ready to go, saving human work time,” Hillman pointed out.

Auto start-stop will also be included. This reduces idle time and saves on fuel. But, customers recharging batteries or needing cab heat will still be able to have access without continuously running the engine.

All International medium-duty and vocational trucks are equipped with the Diamond Logic electrical system.

Hillman also mentioned that the company’s OnCommand Connection is now available via mobile app.

Also, the WorkStar is now available with the Cummins ISB 6.7L engine or Navistar’s own N9 and N10 engines, giving customers choices.

“Our customers demand that we provide more than a cookie-cutter approach to our products,” said Hillman. “[The inclusion of the ISB] allows us to get to the lighter end of the horsepower range.”

The N10 engines will also be available in two new higher power ratings this summer. Those are 385 hp. with a manual transmission and 370 hp. with mated to an Allison transmission.
