Dorman and Diesel Laptops have partnered up to bring you an exclusive training opportunity all about the ins and outs of aftertreatment systems! It’s no news to any of us that these systems have high failure rates that can lead to significant downtime and stress. That’s why this class was designed to give technicians of any skill level a complete understanding of aftertreatment systems, including hands-on training, in just one day. Diesel Laptops has identified the most commonly overlooked areas that cause wasted time and money, and we’ve developed a foolproof, step-by-step troubleshooting plan for dealing with these issues.

Schedule
This class will take place from 8am - 5pm with a one-hour break for lunch that will be provided to students. The first half of the class will be a lecture portion focusing on the EGR system and the DOC and DPF. After lunch, we'll go over the SCR system and then start the hands-on training portion where we'll perform a live regeneration to validate the concepts we just covered and you'll perform labs with learning aids developed by the Diesel Laptops Training Department.

Aftertreatment System Components
You'll learn the function, operation, and the internal view of the diesel oxidation catalyst (DOC), diesel particulate filter (DPF), selective catalytic reduction (SCR) system, and aftertreatment fuel injectors and their alternative names.
See All Topics
Topics Covered:
Regeneration System Operation and Diagnostics:
- Engine controls that regulate the DOC inlet temperature during regeneration
- How to spot low temperature issues during regeneration
- How to clean DPFs and DOCs and inspect them for replacement when removed
SCR System Operation and Diagnostics:
- What diesel exhaust fluid (DEF) is and the importance of verifying concentration with a refractometer
- DEF system operations including pumps, tanks, lines, tank and line heaters, decomp tube, and dosers
- Particulate matter sensor function and operation
- How to address aftertreatment and SCR derates, including what they mean and how certain manufacturers require you to clear them.
Actuators Affecting Aftertreatment:
- Turbocharger and related components (How low boost can cause regeneration issues)
- EGR valve and related components (How EGR function can cause regeneration issues)
- Fuel systems and related components (How fuel-related issues can cause regeneration issues)
- How low power, oil consumption, smoke, and cylinder performance affect aftertreatment

No Fault Codes?
Sometimes a fault code isn't available to help with diagnosing issues with aftertreatment systems. To make diagnosing without a fault code easier, you'll learn about regeneration temperature diagnostics and the cause of regeneration temperature inversions.

Oil Dilution and Regeneration
Our instructors will explain the differences between post-injection and in-cylinder regeneration operations. You'll also learn about oil and fuel dilution issues and byproducts of them.

Injector Programming and Regeneration Issues
You'll learn about the importance of IQA or injector coding when replacing an injector and how it could potentially affect the aftertreatment system.

Benefits for Diesel Technicians
You'll sharpen the skills necessary to simplify diagnosing these seemingly complex systems. This knowledge will help you diagnose vehicles all across the board as this training is not specific to any one manufacturer, and we go over most variations you'll find.

Benefits for Shop Owners and Managers
The skills your technicians learn in this class will help them diagnose equipment quickly and efficiently, resulting in less time wasted on incorrect diagnostics and repairs, ultimately leading to less downtime. Your customers will be breaking down your door when they find out how quickly you can get them back up and running.
