CUMMINS EGR REMOVAL
SERVICE

Deleting the DEF (Diesel Exhaust Fluid), (Diesel Particulate Filter), and (Exhaust Gas Recirculation) systems on a 6.7 Cummins engine is a hot topic among diesel technicians and fleet managers. These systems, mandated for emissions compliance, play a critical role in reducing environmental pollutants but can also create maintenance challenges. This analysis delves into the advantages and disadvantages of bypassing or removing these systems, focusing on technical implications for heavy-duty truck operation.

Additionally, modifying or removing SCR (Selective Catalytic Reduction) systems as part of an aftertreatment solution for emissions control is also considered. Delete SCR components can improve engine performance and efficiency, but it is important to be aware of the legal implications and potential risks associated with such modifications.

PROS EGR DELETE CUMMINS:

Increased Engine Efficiency:

• Removing the EGR system eliminates the recirculation of exhaust gases, which restores full oxygen-rich airflow to the cylinders, optimizing combustion.
• By bypassing the Cummins EGR system, technicians report smoother engine operation and reduced turbocharger strain

Improved Fuel Economy:

• The fuel consumption associated with DPF regeneration cycles is eliminated.
• EGR delete for 6.7 Cummins models can lead to a measurable savings in fuel usage by avoiding the inefficiencies caused by reduced air intake quality.

Reduced Maintenance Costs:

• Technicians frequently cite failures in components like injectors, NOx sensors, and DPF pressure sensors as high-cost fix.
• Deleting these systems prevents recurring issues like clogged filters, DEF pump failures, or stuck valves.

Enhanced Performance and Longevity:

• Deleting emissions systems reduces backpressure in the exhaust, allowing the engine to run cooler and more efficiently.
• A Cummins EGR delete can result in better throttle response, higher torque output, and a longer-lasting engine due to lower thermal stress.

CONS EGR DELETE CUMMINS:

Emissions Non-Compliance:

• Removing emissions systems renders the vehicle non-compliant with EPA and DOT regulations, which can result in significant fines.
• Vehicles with deleted systems are not allowed on public roads in many regions.

Void Manufacturer Warranty:

• Any modifications to emissions systems typically void the Cummins factory warranty.
• Repairs or replacements for issues like injector failure or turbocharger damage would be fully out-of-pocket.

Potential Diagnostic Challenges:

• Deleted trucks can complicate diagnostics and repair processes if not properly tuned.
• Without the correct ECU reprogramming, technicians may encounter fault codes, limp mode activation, or unstable engine performance. To prevent fault codes, it is crucial to unplug the EGR sensors connectors during the EGR delete process.

Environmental Considerations:

• The absence of these systems significantly increases NOx and particulate emissions.
• Some fleet operators face reputational risks for non-compliance with green initiatives or customer expectations.

DISCLAIMER FOR OFF-HIGHWAY TUNING

It is important to note that off-highway tuning, including DPF delete programming, is illegal in some areas and can void the manufacturer’s warranty. Off-highway tuning refers to modifications made to a vehicle that are not intended for use on public roads.

By installing off-highway tuning products, you are assuming all liability for the use of the vehicle and any resulting damages or injuries. These modifications may not comply with the laws and regulations in your area, and you could be subject to fines and penalties if caught using the vehicle on public roads.

Off-highway tuning products are intended for closed-course racing or off-road use only and are not legal for use on public roads. It is your responsibility to ensure that you are using these products in compliance with all applicable laws and regulations.
