Performance Increase
Disabling the EGR system usually allows the engine to take in cooler, cleaner air, which can increase combustion efficiency. An increase in engine performance can be observed after disabling the EGR. This increase is usually between 5% and 10%, and may vary depending on engine condition, settings, and other variables.

Cleaner Engine Operation
With the EGR system disabled, exhaust gases no longer flow back into the combustion chamber, resulting in cleaner engine operation in Kenworth trucks. This can help reduce carbon buildup and soot, extend the life of engine components and reduce maintenance.

Fuel Economy
A slight improvement in fuel consumption can also be observed. Fuel savings after EGR deactivation are usually between 5% and 15%. This saving is due to the engine operating more efficiently and less recycling of unburned fuel.

Better Throttle Response
The EGR system can slightly reduce throttle response due to exhaust gases being returned to the combustion chamber. Deactivating the EGR can improve the vehicle's driving dynamics by providing quicker and more direct throttle response. This is particularly advantageous for performance-oriented drivers.

Reduced Cooling System Load
The EGR system works to reduce combustion temperature, which can put additional load on the engine's cooling system. Disabling the EGR system with the Kenworth EAS4 EGR Emulator reduces this load, provides more efficient cooling, and reduces the risk of overheating.

Less Engine Oil Contamination
Exhaust gases returning to the combustion chamber can mix with engine oil, causing it to become contaminated more quickly. Disabling the EGR system helps keep engine oil cleaner, extending oil change intervals and improving the overall health of the engine.

Extending the Life of Emission Control Systems
The EGR system can place additional stress on other emissions control components such as the catalytic converter and diesel particulate filter (DPF). The Kenworth EAS4 EGR Emulator can extend the life of these components and reduce maintenance needs.

Supported Models

The EGR cancellation emulator is compatible with MX-11 and MX-13 models with Paccar engines. It works with a wide range of models, especially the Kenworth series, thus optimizing your engine performance and helping you prevent malfunctions that may arise from the EGR system.
