GM Duramax 6.6L 11-14 LML
RPO LML (VIN code “8″) is the latest version (2011 – present) of the
Isuzu/GM Duramax V8 diesel engine and actually a further advanced
version of the LMM engine with the majority of the changes addressing a
required drastic reduction in engine emissions. Some mechanical aspects
of the engine, such as piston oil flow design for improved temperature
control and oil pump design, were also improved to enhance durability
engine was significantly updated for 2011 to provide improved exhaust
emissions that comply with the new federal emission standards for diesel
engines, provide better engine rigidity and further noise reduction.
New 29,000 PSI piezo injectors, a complete fuel system-hardening to
tolerate up to 20% biodiesel mixtures and urea injection (to reduce
Nitrogen oxides) with a 5.8 gallon urea tank are updating the fuel and
emissions systems. This engine also has now 9 fuel injectors, one
directly injecting in the exhaust tract, to allow raw fuel injection
during the particulate filter recycling routine. This was previously
accomplished by running raw fuel through the engine via the engine fuel
injectors without igniting the fuel (valves were kept open), but risks
of washing down cylinder walls and causing engine damage are increased
with the use of Biodiesel. The RPO LML engine is rated at 397 horsepower
at 3000 rpm and 765 lb.-ft. of torque at 1600 rpm.
