Don’t overlook truck DEF filter importance

It might be time to stop pointing the finger at the truck’s DPF and take a closer look at aftertreatment issues.

Considerations for reconditioned diesel particulate filters

“Reconditioned”, baked or cleaned diesel particulate filters (DPF) units offer short term financial benefit. In terms of  functionality, the overall cost to the customer is much higher. In reality these processes can deactivate the original catalyst and stress the DPF substrate to an even greater extent during normal active regen cycling. Reconditioned units present an

International pulls the sheet off of its S13 integrated powertrain

At a press event at the Las Vegas Motor Speedway, International introduced its S13 integrated powertrain. Developed in collaboration with the TRATON Group, the S13 integrated powertrain was created from a clean sheet design and consists of three distinct components–an engine, a transmission and an aftertreatment system–all designed and developed concurrently to ensure maximized compatibility

It’s easy to blame the DPF, but what’s causing the aftertreatment problem?

The diesel particulate filter is the whipping boy of the heavy-duty truck aftertreatment system. It can be costly to replace as obvious culprit of fault codes … or maybe a little too obvious. The component can shoulder a lot of the aftertreatment service the blame, but did it really cause it? After all, it’s the

Eaton develops 48-volt aftertreatment heater controller

Eaton has recently announced its eMobility business has introduced a 48-volt programmable power electronics control unit for electrically heated catalysts that can be used by commercial vehicle manufacturers to meet tightening global emissions regulations, the manufacturer noted. Rapidly warming up the exhaust aftertreatment catalyst, and keeping it warm during low engine load operation, is essential for optimal

The truck service similarity between ADAS and aftertreatment

Advanced driver assistance systems, or ADAS, like advanced cruise control and active lane keep assist technologies are helping to improve truck safety, but these systems are starting to create service mysteries for shops as they roll into bays. they’re complex systems that can make seemingly basic repairs like a windshield replacement a costly and time-consuming

Talking biodiesel viability & aftertreatment technology

Biodiesel has been cropping up in more decarbonization conversations as the industry drives toward lower (and sooner than you think: zero) emissions. Volvo Trucks North America mentioned biodiesel during its ATA MCE press conference. While we’ve had the likes of REG talking about the potential benefits of biodiesel, its appeal seems to be gaining a

How to deal with trucking’s DEF sensor shortage

Supply chain shortages hit the trucking industry hard and no more so evident than in new trucks that are slowly rolling off the line. It’s the dreaded microchip shortage that shows no sign of letting up, but while there’s been plenty of talk of not being able to get new trucks, fewer are talking about

Diesel engine aftertreatment service tips

It’s probably not a surprise to hear that a large number of the most common issues with today’s diesel engines involve aftertreatment systems. Recently, Fleet Equipment discussed the causes of problems such as excess regeneration activity and how to determine if the regeneration frequency with their engines is within a normally accepted range. Our panels

Eaton highlights diesel engine technology to curb emissions

Eaton’s vehicle group has demonstrated cylinder deactivation (CDA) as an effective technology for meeting future global emissions requirements for diesel-engine powered commercial vehicles, the company says. In a press release, Eaton explained that, to date, the technology has been evaluated with a close-coupled selective catalytic reduction (SCR) aftertreatment system with and without a 48-volt electric

Electrical system maintenance to improve aftertreatment performance

Running a regen is an easy out to deal with aftertreatment issues, but even if it fixes the problem in the short term, you’re sure to see that same truck back in the shop with the same set of aftertreatment-related faults. You need to get to the root of the aftertreatment system’s problem, and the
