In 2011, when the LML Duramax was introduced, it had a host of new upgrades, as there were very few parts that were carried over from the previous generation trucks. The injection system was overhauled again with a massive change to piezoelectric injectors, this utilizes a stack of Piezo crystals that would expand and contract with electrical current. In addition to this the LML received a whole new injection pump, CP4, that was able to hold a higher pressure for longer durations than the previous injection pumps. It was not immediately recognized that the CP4 had a design flaw that could lead to a catastrophic failure and required a complete fuel system replacement. The emissions system was completely new as well with the introduction of Diesel Exhaust Fluid (DEF).
This new process required DEF to be injected into the exhaust stream combined with heat and the materials from the Selective Catalyst Reduction (SCR) causing a chemical reaction to decrease the amount of harmful NOx emitted from the exhaust system.
