Understanding the EGR Delete Kit for the 6.7 Cummins 2012
Introduction
The EGR (Exhaust Gas Recirculation) delete kit for the 6.7 Cummins 2012 is a modification designed to improve the performance and longevity of the vehicle’s engine. This article aims to provide a comprehensive understanding of what the EGR delete kit is and its significance for Cummins owners.
What is the EGR System?
The EGR system is an emissions control mechanism found in modern diesel engines, including the 6.7 Cummins. Its purpose is to reduce nitrous oxide (NOx) emissions, which are harmful to the environment. The EGR system achieves this by recirculating a portion of the exhaust gases back into the engine’s intake manifold, lowering the combustion temperature.
The Problems with the EGR System
While the EGR system has its benefits, it also poses several issues, especially in older engines like the 6.7 Cummins 2012. Over time, the recirculated exhaust gases tend to leave carbon deposits within the intake manifold and EGR system components. These carbon deposits can restrict airflow, hinder performance, and potentially lead to costly repairs. Additionally, the EGR system can cause excessive soot buildup in the engine, affecting fuel efficiency.
The Significance of the EGR Delete Kit
The EGR delete kit is a modification that allows Cummins owners to eliminate or bypass the EGR system entirely. By removing the EGR system, the engine can operate at a more optimal combustion temperature, resulting in improved performance, reduced wear and tear, and increased fuel efficiency. The EGR delete kit essentially prevents the recirculation of exhaust gases, thereby minimizing carbon deposits and soot buildup in the engine.
Installation and Components
The EGR delete kit typically includes various components that allow for the removal of the EGR system. These components may vary depending on the specific kit and manufacturer, but commonly include EGR valve delete plates, EGR cooler delete pipes, and a tuning device or ECU programmer. The tuning device is crucial as it reprogrammes the engine control unit (ECU), ensuring proper engine management without triggering any fault codes.
Necessary Considerations
Before installing an EGR delete kit, it is essential to consider local emissions regulations and laws. In some regions, tampering with emissions control systems is illegal, and you may risk facing penalties or even voiding your vehicle’s warranty. Additionally, removing the EGR system may cause your vehicle to fail emissions tests, making it unsuitable for road use in certain areas.
Conclusion
The EGR delete kit for the 6.7 Cummins 2012 provides Cummins owners with an opportunity to address the drawbacks associated with the EGR system. By bypassing or eliminating the EGR system, this modification improves engine performance, reduces carbon deposits and soot buildup, and enhances fuel efficiency. However, it is crucial to consider local regulations and the potential consequences before proceeding with the installation of an EGR delete kit.
