How does EGR work on a Cummins diesel engine?

EGR, or exhaust gas recirculation, is an emissions-control system that redirects a portion of the engine’s exhaust gases back into the intake system. Its purpose is to help reduce certain emissions produced during diesel combustion.

Over time and depending on operating conditions, particulates contained in the exhaust gases can contribute to deposits within the EGR and intake systems. These deposits may affect engine operation and can increase maintenance requirements.

Why consider EGR delete for an off-highway Cummins engine?

For an eligible off-highway application, an appropriate tune can modify the operation of the EGR system. Results depend on the specific engine, its condition, configuration and operating environment.

Depending on the application, owner-operators and fleet managers may be looking for benefits such as:

• Optimized engine efficiency: tuning matched to the engine configuration may help improve engine operation under certain conditions.
• Improved engine response: depending on the engine and calibration, changes in engine response and performance may be noticeable.
• Reduced EGR-related issues: deposits and failures involving EGR components can contribute to additional maintenance requirements and engine downtime.

Results vary by engine. The engine model, year and configuration should always be verified before any tuning service is performed.

How can I check whether my Cummins engine is compatible?

Compatibility primarily depends on the Cummins engine model, year and electronic configuration. Review the supported-engine table above or provide this information to Diesel Spec so our team can determine which tuning services are available for your engine.

Contact Diesel Spec to confirm your engine configuration before proceeding with a tune.
