After removing EGR, your vehicle can operate more stably. However, some problems will arise if we do not entirely dismantle parts related to the exhaust gas recirculation system, such as the Cummins throttle valve.
This set of valves is the leading cause of unstable operation even though we have removed the EGR properly. To end this annoying situation, you should refer to using the 6.7 Throttle Valve Delete 6.7 Cummins via the guides in this article.
What Does A Throttle Valve Cummins Do?
This type of valve has a specialized structure to control the transportation of liquids, gasses, or even liquefied gasses in the engine system. This unit has two main operating mechanisms, manual and automatic. Manual faucets depend on handwheels and levers, while mechanical valves require regulators.
The Cummins throttle valve is closely related to the exhaust gas recirculation (EGR) system that manufacturers have integrated into the vehicle to reduce emissions. To understand the true purpose of a throttle faucet, you need to know how EGR works.
This system works with exhaust gasses generated after the engine inside the vehicle ignites the fuel.
Instead of completely escaping into the environment, this gas mixture will go to the electronic pressure control valves of the exhaust gas recirculation system.
This mechanism allows a large stream of air to split into smaller streams. Only one current can fly out while the rest will travel back to the motor for reuse.
Cummins throttle faucet is the part that controls the return exhaust flow through the EGR.
The faucet is located between the intake horn and the rest of the exhaust gas recirculation system, so the device will push the remaining air in the other direction when closed.
Without a throttle valve, the exhaust gas will not be able to return to the EGR but go straight out.
What Is A Throttle Valve Delete On A Cummins?
Throttle Valve Delete 6.7 Cummins Kits
Many users forget about disposing of the faucet set after removing the EGR from their vehicle.
The close connection between the Cummins throttle faucet and the exhaust gas recirculation system allows the two components to self-regulate when operating.
More specifically, the faucet will work to adjust the ratio between the intake air and the recirculated exhaust gas. Meanwhile, the EGR system will suck in the air after re-adjustment, circulate it and finally return it to the system.
When EGR disappears while the faucet is still open and closed, the exhaust gas will still circulate as usual.
However, there will be no alternative source of intake air, and it will cause asphyxiation in the internal system. As with many other suffocation conditions, a build-up of gas in the faucet will damage and disable the vehicle. In addition, the 6.7 Cummins throttle also obstructs the airflow even though we no longer need this operation.
Throttle delete will help us ultimately remove the adverse effects from this valve set after you have removed the EGR from the system.
These kits are physical replacement parts to ensure the valve doesn’t close. We can see that the cap and the fixed cuff keep the faucet in place.
Throttle delete will help us remove the butterfly faucet and disable the inherent ability to open and close when the system is still connectable to the EGR.
About Throttle Valve Delete Install On 6.7L Cummins
Unlike when we remove the EGR, the throttle valve operation is much simpler. This part is inaccessible positions, and it is not difficult to determine the shape.
You need to open the capo and use a few operations to access the faucet set.
However, the actions you are about to perform will also have many adverse effects if mistakes occur. That is why we need to be careful in all our activities.
The first step is to remove the hose clamp from below and remove the four bolts. With this action, you have completed half of the basic steps.
Next, we removed the metal pipe and the fixing belt from the eraser and put the line in the part we removed and fixed with the attached strap. When this step is done, we have completed the necessary operations.
However, replacing any part is not simply replacing the physical mechanisms but also solving problems with the software system.
You need to check and override to avoid the error code appearing and the car not working because we have reached too deep inside the engine. The control will lock the vehicle if you don’t try to fool it.
Is Throttle Valve Delete Necessary?
If you care about your vehicle’s performance and want to ensure that the car is in the most stable operation, removing the throttle valve is necessary.
The throttle faucet will close when you turn off the car engine and not affect much. Modern vehicles also have built-in airflow control mechanisms to minimize the possibility of flammable or explosive gasses.
But you can still get into trouble with your control systems if, unfortunately, scans don’t detect changes in airflow. In this case, the whole system will not be able to operate because the controller has locked all the starting mechanisms.
You can only start the car once you have fixed the problem with the throttle valve. The repair process is not too complicated, but you will undoubtedly have to spend time and effort manipulating the faucet.
When we operate the vehicle at below-average speed and do not have to move through too unstable areas, you do not need to worry about this faucet set.
At this point, we can choose the simplest option to ignore this part.
6.7 Cummins Throttle Valve Problems
There are many problems that the 6.7 Cummins throttle valve can cause to the system under certain circumstances. Most of these cases are random or only appear when the car has been operating at high performance for a long time.
You should still consider the issues I am about to address below. Any danger that appears can directly or indirectly cause trouble to us. Therefore, paying attention and taking early remedial measures is never superfluous.
Butterfly valve blockage
6.7 Cummins throttle valve can get stuck or blocked due to the impact of exhaust gas from fuel combustion.
In addition to CO or CO2, there are dust, soot, and microscopic particles inside this exhaust gas mixture.
Despite its small size, the long-term accumulation of the above agents will make the valve jammed and unable to open or close.
If there is EGR, the airflow moving through the faucet will be much cleaner, thereby limiting problems caused by dirt and physical agents.
Unstable airflow
All valves, including the 6.7 Cummins throttle valve, regulate the flow of liquids or gasses. If you removed the EGR with the delete kit and filled the gap with an empty tube, the gas can still move.
But now, there will be no airflow to return to the throttle valve, causing the part to open and close continuously without self-control.
The valve will close tightly or open completely, creating a precondition for gas asphyxiation. Not only does it hurt the vehicle, but asphyxiation can also cause the vehicle to stop suddenly on the road.
When driving a vehicle at high speed, a sudden stop will be a disaster for safety.
Problems with sensors and smart systems
Technology development allows manufacturers to integrate many mechanisms to make their vehicles safer and more stable.
One of those mechanisms is the intelligent management and sensing system. This system will not ignore any changes in the structure of sensitive electronic components.
Then it will intervene and lock the car until we recover and scan the error again. The opening and closing action of the 6.7 Cummins throttle valve when there is no EGR is often quite unusual and can create many other problems.
It’s not too difficult to understand when the sensor will not let your car start if we let the valve operate arbitrarily. If we want to use the vehicle again, we need to intervene.
Conclusion
Throttle Valve Delete 6.7 Cummins is an action you can consider minimizing valve effects on your vehicle’s performance.
Through today’s article, I hope that you have gained the necessary knowledge to manipulate. Besides, it will also be easier for you to make decisions based on the intelligence that I have brought.
