In diesel engines in particular, EGR systems come with serious drawbacks, one of which is a reduction in engine longevity. For example, because the EGR system routes exhaust gas directly back into the cylinder intake without any form of filtration, this exhaust gas contains carbon particulates. And, because these tiny particles are abrasive ...
Balancing the percentage of cooled external EGR with the hot internal EGR generated by a VVA system, makes it possible to control the in-cylinder temperature. While electro-hydraulic and camless VVA systems offer control over the valve event, the componentry for such systems is currently complicated and expensive.
The block designation was changed to J to reflect the changes to the new engine, which included power assembly and block redesigns, as well as the addition of a two-stage turbocharging system consisting of three turbochargers. [12] Other new features are an EGR system to reduce exhaust emissions and double-walled fuel injection to increase safety.
In addition to changing the fuel, US engineers have also come up with two other principles and distinct systems to all on-market products that meet the U.S. 2010 emissions criteria, [citation needed] [needs update] selective non-catalytic reduction (SNCR), and exhaust gas recirculation (EGR). Both are in the exhaust system of diesel engines ...

The series-turbo system is set up to provide a better throttle response while in motion to give a power flow more like a naturally aspirated engine. The 6.4 L also has a DPF and dual EGR coolers which are capable of reducing exhaust gas temps by up to 1,000 degrees before they reach the EGR valve and mix with the intake charge.
The L56 is emissions controlled with EGR and catalytic converters. The L65 engine has neither an EGR system nor a catalytic converter, but there is a soot trap on L65 engines that is often mistaken for a catalytic converter. GM was the first manufacturer to introduce an electronically-controlled fuel injection system into a diesel pickup truck. [2]
