The Used Truck Association sponsored a webinar last week to introduce the used truck market to the International N13 engine.
The N13 was released about four years ago and has recently been finding its way into the aftermarket.
“We have seen great results with this engine and now they are beginning to creep into the secondary market,” says Navistar’s director of pricing, marketing and strategy, Brock Frederick.
The N13 was introduced in 2013 to replace the Maxxforce 13 and meet new federal emissions regulations.
The engine uses Cummins Emissions Solutions, Frederick says.
“We partnered with Cummins so we feel everyone in the industry should be comfortable with this product,” Frederick says.
Navistar’s On-Highway Marketing Manager Jim Nachtman says several of the engine’s design changes from the Maxxforce 13 have been popular in the new sales market.
“There is a new thermal valve to house the fuel doser and NOx sensor and it provides higher temperature coolant to the low temperature EGR cooler to prevent soot build up,” Nachtman says. “It’s known as a hot side re-plumb.”
The Cummins Emissions Solutions after treatment uses Diesel Emission Fluid to clean the exhaust, Nachtman says.
As part of the Selective Catalytic Reduction System, Nachtman says there several benefits of the N13 engine.
Nachtman says the SCR creates less soot and requires less regenerations, improving after treatment system uptime.
“Less soot extends power cylinder, bearings and valve train life,” he says.
The company has found that the N13 creates a two-percent fuel economy improvement over the last built Maxxforce 13 engines, which results in an estimated savings of $800 annually on fuel costs.
