LML

By the time the 2010s rolled around, the Duramax engine was on its 6th iteration, the LML. As an extension of the LMM engine that introduced heavy emissions regulation technology to the engine, there are quite a few ways to improve on the 2011-2016 LML. That is actually a good thing, as the LML is…

Aside from the DPF filter and other exhaust-related emissions systems, the Duramax LML also has an EGR system. EGR stands for exhaust gas recirculation, which essentially routes exhaust gases back into the engine. EGR systems have a few components, most notably the EGR cooler, than are prone to failure. Additionally, it’s bad for engine longevity….

GM replaced the Duramax LMM in 2011 with the LML in part due to emissions requirements. One of the new features of the LML was the addition of he SCR system in conjunction with DEF fluid, which GM claims reduced emissions levels by over 50 percent. However many early model LML’s experienced SCR and DEF…

The 6.6L Duramax LML hit the market in 2011 and stuck around through 2016 after which it was replaced by the L5P. The LML produced a solid 397hp and 765lb-ft. of torque. While the LML’s torque output fell slightly short of the 6.7 Powerstroke and 6.7 Cummins, the engine produced just about as much power…

The 6.6L Duramax LML was released in 2011 and produced through 2016. Producing 397hp and 765lb-ft. of torque, the LML delivered solid power and was a strong competitor to Ford and Cummins 6.7L diesel engines of the time. While the LML’s power is just about as much as anyone would need, there are still some…

Following the short lived LMM engine, the Duramax LML was introduced in 2011. Featured in the same 2500 and 3500 HD work trucks, the LML sported the same 6.6L turbo-diesel design that Chevy diesel trucks have been using since 2001. However, the LML was actually the biggest overhaul Duramax had done to the 6.6, claiming…
