Carbon B Gone and the Science of DPF Cleaning: Clearing Up the Confusion
Introduction Fleet managers and diesel owners are always looking for easier ways to keep DPFs clean. Products like Carbon B Gone market themselves as chemical solutions that “break down carbon and ash.” In some of their own wording, the claim goes further: the ash...
Keep Rust Off Your Nuts (And Bolts Too)
Rust is like that one coworker who never showers: once it shows up, it spreads, stinks, and nobody wants to deal with it. On trucks, fastener corrosion is not just ugly, it is expensive, dangerous, and one stripped stud away from ruining your day. So how do you keep...
The 2015 Freightliner Cascadia Emissions Challenge: How Fuel Mapping Issues Lead to DEF Quality Codes and SCR Damage
In the intricate world of diesel emissions systems, precision is paramount. For the 2015 Freightliner Cascadia, however, a critical flaw in fuel mapping during its production has left many truck owners facing persistent, costly issues. Late-model 2014 and early-model 2016 Cascadias also suffer from this problem, which manifests most acutely when trucks are under load, climbing grades, or hauling heavy weights.
The Road to Zero Emissions: Navigating Regulations, Challenges, and Solutions for Fleets
As California forges ahead with groundbreaking emissions regulations, the trucking industry is left grappling with how to adapt to these sweeping changes. From the Advanced Clean Trucks (ACT) and Advanced Clean Fleets (ACF) rules to the EPA’s approval of CARB’s...
Freightliner M2 Emissions and Maintenance Guide
The Freightliner M2 is one of the most widely used medium duty trucks in North America. From delivery fleets and municipal trucks to ambulances and vocational work trucks, the M2 is everywhere. With that workload comes one reality: emissions problems. If you own or...
On-Truck DPF Cleaning Chemicals Compared Side by Side
Introduction Truck downtime is expensive, and nobody likes pulling a diesel particulate filter (DPF) off a truck just to get it cleaned. That’s why the aftermarket has long pushed “on-truck” chemical cleaners—spray it in, let it soak, run the truck, and the filter is...
Busting the Myth: The Truth About Ships vs. Trucks and Diesel Emissions (and No, You Can’t Delete Your DPF)
When the rubber meets the road in the debate over diesel emissions systems, a question often arises in trucking circles: If massive cargo ships crossing the oceans don’t have emissions systems, why should trucks on highways be saddled with them? It’s a common...
Revoy’s Battery Dolly: Turning Diesel Tractors into Hybrids—With No Upfront Investment
Can you really turn an existing diesel tractor into an EV with no upfront investment and cut fuel expenses by up to 10% and emissions by up to 90%? If it sounds too good to be true, it often is. But sometimes, it’s the coolest thing since sliced bread or robot lawn...
Busting the Chevron Myth: Why Deleting Your DPF Is Illegal (No Matter What You Read Online)
There’s a myth making the rounds in trucking circles, fueled by internet misinformation, that the infamous Chevron case somehow gives drivers the green light to delete their diesel emissions systems. This couldn’t be further from the truth. Let’s set the record straight: the Chevron case has absolutely nothing to do with diesel emissions compliance, and deleting your DPF is still illegal under U.S. law.
If you’ve stumbled across social media posts or forums claiming otherwise, it’s time to dig deeper into the facts. Here’s everything you need to know about the Chevron case, diesel emissions laws, and why believing in this myth could cost you big.
The Knoxville Study and The Fallacy of Deleted Emissions Systems: Unmasking the Dirty Truth About Diesel Pollution
When we think about the backbone of American commerce, the image of a diesel truck barreling down the highway often comes to mind. These trucks, carrying everything from fresh produce to industrial machinery, keep our economy humming. But beneath the roar of their engines lies an inconvenient truth: diesel trucks, especially those with tampered emissions systems, are major contributors to air pollution.
Big Brother is Watching Your Diesel Exhaust: A Warning to Anybody With a Deleted, Defeated or Illegally “Tuned” Diesel Emissions System
In an age where the fight against climate change is a global priority, the trucking industry is taking center stage. Diesel trucks are the backbone of the economy, hauling goods across continents and keeping supply chains alive. But they’re also a key contributor to air pollution, emitting nitrogen oxides (NOx) and particulate matter (PM) that harm both human health and the environment. Enter remote emissions monitoring — a technology that’s transforming how regulators, fleet managers, and even the public approach diesel emissions.
Did Trump “scrap diesel emissions rules”? No. Here is what changed and what did not.
Overview: Deleting or tampering is still illegal everywhere. The Clean Air Act bans removing or disabling emissions controls and bans defeat devices for on-road and nonroad engines, including any nonroad engine subject to federal regulations. See 42 U.S.C. § 7522 and...
Diesel Emissions Tampering Crackdown: How EPA Fines and Jail Time Will Cost You Big if You Delete, Defeat, or Illegally “Tune” Your Diesel Truck’s Emissions System
In the trucking world, a diesel engine is more than just machinery; it’s the beating heart of your livelihood. But with great power comes great responsibility—especially when it comes to emissions. In recent years, the EPA and state regulators have tightened their grip on diesel emissions, bringing heavy fines, lawsuits, and even jail time to those who tamper with or “delete” their emissions systems. For trucking companies and independent drivers, understanding these laws isn’t just good business; it’s a survival strategy.
Scania’s DPF-Free Tier 4 Final Diesel Engine: A Game-Changer for Emissions Compliance
In the world of diesel engines, few manufacturers have challenged the status quo like Scania. Known for its innovative engineering, Scania developed a line of Tier 4 Final diesel engines that meet stringent emissions standards without relying on a Diesel Particulate Filter (DPF). This achievement isn’t just a marvel of engineering; it raises significant questions about the future of diesel engine design and emissions compliance.
How Public Safety Vehicles, U.S. Military Branches, FEMA, the National Park Service, and Ambulances Navigate Diesel Emissions Regulations
In today’s regulatory environment, diesel emissions are tightly controlled, with strict standards aimed at reducing harmful pollutants like nitrogen oxides (NOx) and particulate matter (PM). These emissions contribute to environmental damage and public health risks, prompting federal and state governments to mandate the use of emissions control systems such as Diesel Particulate Filters (DPFs) and Selective Catalytic Reduction (SCR) systems.
