Exhaust Gas Recirculation, Don't Delete Your EGR System
HTML-код
- Опубликовано: 18 окт 2024
- In this video, we’re taking a close look at the ISX EGR system. We’ll walk through how it functions, starting from the exhaust manifold, and explore the potential issues that arise when deleting this system.
What You Will Learn:
How the EGR system controls exhaust gas and intake air
Key components of the ISX EGR system and their functions
The risks and downsides of deleting the EGR system
Step-by-Step Guide/Tutorial:
EGR System Overview:
Exhaust gases flow from the exhaust manifold into the EGR cooler, where coolant helps reduce gas temperature before reaching the EGR valve.
The EGR valve controls the amount of exhaust gas mixed with clean air from the turbo’s charge air cooler, which then enters the intake manifold through a venturi, ensuring the right combustion temperature.
Potential Pitfalls of Deleting:
Legal Issues: Deleting the EGR system can result in your vehicle being non-compliant with emissions regulations, limiting where you can operate.
Loss of Engine Braking and Torque Curve: Removing the VGT (Variable Geometry Turbo) reduces engine braking and low-end torque, both of which are crucial for efficient operation.
Coolant Flow Issues: Without the EGR cooler, the coolant path from the water pump to cylinders 5 and 6 is disrupted, increasing the risk of cylinder scoring and overheating.
Increased Combustion Temperatures: With 100% clean air entering the engine, combustion temperatures rise significantly, from the typical 600-700°F with EGR to potentially 1,200-1,300°F without it. This can cause engine damage if not closely monitored.
Consequences of Deleting:
While removing the EGR system may seem cost-effective upfront, it often leads to long-term engine damage, including burned pistons, cracked valves, and costly overhauls.
Key Benefits:
Engine Longevity: Learning and maintaining the EGR system preserves your engine’s performance and lifespan.
Avoid Costly Repairs: Properly operating with the EGR system in place can prevent major engine failures that result from overheating and improper combustion.

Really glad I watched this video because I didn’t know several points about the turbo and EGR….Thanks!
Glad it was helpful!
Hi thanks for the video I just borck my head it's too hot what u can do to run less hot plz
The series 600 was good. Can make it like that and just plug everything up.
Really well explained video,my one question is,in order to delete all of the after treatment parts do I have to delete the egr cooler also or can I leave it on, the reason I’m asking is because there is a national back order on def sensor that I need, no body has them sensors in the nation so my 2020 389 Pete truck is down bc a def sensor shortage, thank you
It is best to replace sensor and keep all after treatment working as it should be.
This is very disappointing, I was ready to delete. I'm hoping to reduce the amount of soot that collects in the intake system and a delete seemed like a easy way to do it. Your video makes great points though, thanks for the explanation. Back to the ol' drawing board 🤪
Anyway to clean up the cooled egr gas before it gets into the intake side of the engine ? Intake manifold and IMAP sensor get all dirty with all the carbon build up. . DPF on egr exhaust after being cooled ? Thanks
Hi robert torres! Rob answered your question in our most recent video. Check it out here: ruclips.net/video/VWSAzGiTNls/видео.html
This is a chronic issue in our industry. Repair facilities that are unable to diagnose and service these systems turn to deletes but have no idea of the consequences.
Can you explain why they run unfiltered gas into engine instead of clean ? Seems soot is a major issue and causes most issues both mechanical and electronic .
Mechanical engines are not nearly as "clean" running as the electronic engines
The reason for the EGR is to allow inert gas to displace charge gas and control combustion temperature
You have a good point... when something is not correct in the engine soot production can go up. Being unfiltered can cause many issues due to this.
Caterpillar has a system called CGI that filters the gas then re introduces it to the engine.
good day sir.you have pcv valve w/c blowby coming out down to intake line to turbo the to intake manifold to be burned again since this is not O2 this also reduce temp during combustion process.sir is this not enough to reduce thermal stress on cylinder blocks.thanks for your kind reply.
Most Diesel engines (Heavy Duty) do not run a PCV valve.
Thx
Steven, thanks for watching!
Nice video bro! Really well explained.
This feels like a double edged blade. Egt not high enough to cleanly burn the diesel thus recirculating unburned exhuast gases. Then whats not being recirculated and reburned is being scrubbed in the dpf. Especially in high load situations.
Please give us a call for further trouble shooting. We will need some engine info as well. Thank you! (855) 447-1453
I'm about to buy a truck but it has the dpf and egr deleted.. Is it possible to put the systems back on and have it tuned back to stock?
Yes, it can be returned to stock! Reinstall the original components and have it re-tuned back to OEM Specs. If you're looking for what components are needed, give us a call with the Make / Model / Engine Serial Number.
