Does LML Duramax have EGR?
Starting in 2011 the Duramax LML engine featured a much larger EGR and EGR cooler. Cooling the exhaust gas is a crucial piece of emissions equipment working. Colder temperatures mean more air can be compacted into a given area which helps reduce combustion temperatures.
How does the EGR work on a Duramax?
Halsten says the Duramax EGR only operates at idle and cruise where it allows “inert gases” into the cylinders so the engine can run leaner for optimum mpg while keeping the combustion chamber cooler and reducing NOx. “The EGR is automatically turned off under heavier throttle load and WOT to maximize power.
What size Turbo does a LML Duramax have?
6.6L Duramax LML
| Compressor | ||
|---|---|---|

Is a 6.6 Duramax a twin turbo?
Known internally at Banks as the Super-Turbo, this blown and twin-turbo’d 6.6L Duramax engine was built for a military-spec offshore boat. Though this LBZ-based engine was intended for use in the ocean, there’s no reason one of these babies couldn’t end up in the engine compartment of your next project.
What year did Duramax start using EGR?
In 2001, the Duramax turbo diesel was introduced to the GM 3/4 ton, 1 ton trucks and commerical trucks. In 2004.5, the EPA required a catalytic converters (Cat) and exhaust gas recirculation (EGR) on the LLY engines.
How much HP does a twin turbo Duramax have?
This resulted in an output of 650 hp and 1,215 lb-ft of torque, so the overall gain was 375 hp and 760 lb-ft of torque at the rear wheels.
Are Duramax turbos water cooled?
all duramax turbos have water-cooled center sections.
What does EGR delete do on Duramax?
Essentially an EGR delete removes the EGR valve/motor assembly along with the EGR cooler etc. It requires serious plumbing changes to the exhaust and intake and in my opinion is only advisable for the hard core racer.
What happened to the Duramax LML EGR coolers?
The coolers were much too small and the EGR itself was grossly undersized for the work it was doing. Starting in 2011 the Duramax LML engine featured a much larger EGR and EGR cooler. Cooling the exhaust gas is a crucial piece of emissions equipment working.
What is a Duramax LML engine?
Starting in 2011 the Duramax LML engine featured a much larger EGR and EGR cooler. Cooling the exhaust gas is a crucial piece of emissions equipment working. Colder temperatures mean more air can be compacted into a given area which helps reduce combustion temperatures.
What is the best turbo kit for a Duramax?
Twin turbo kits for Duramax engines to provide the best response time, improve towing capabilities as well as providing the lowest EGTs. Screamin Diesel Performance, INC.
What does Def do on a Duramax EGR system?
This is primarily for the 2011-2016 Duramax EGR system however, most of it applies to all 2011 + diesel pick-up engines. 1. DEF reduces the usage of EGR The EGR uses inert gas (exhaust has no oxygen in it) and recirculates that gas into the combustion cylinder.
