Integrated Cylinder Heads/Exhaust Manifolds: the LFX’s new cylinder head design has a revised intake port design that enhances airflow to the combustion chambers. Larger-diameter intake valves are used in the heads and work in conjunction with new, longer-duration intake camshafts to provide the engine’s boost in horsepower. By using larger valves and holding them open longer, more of the air is pulled into the combustion chamber, for a more powerful combustion. The exhaust manifold is incorporated with the cylinder head, which saves weight, reduces complexity and helps promote a quicker light off of the catalytic converter, which further helps reduce emissions.

Aluminum Engine Block & Integral Oil Pan: the 3.6L V6 VVT’s engine block is cast from A319 aluminum alloy. This aluminum-intensive construction means less weight and greater efficiency than conventional cast-iron engines – and less weight translates to improved vehicle fuel economy. The sand-mold-cast block features strong cast-in iron bore liners, six-bolt main caps, and inter-bay breather vents. A cast aluminum oil pan is stiffened to improve powertrain rigidity and reduce vehicle vibration. Read more: http://gmauthority.com/blog/gm/gm-engines/lfx/#ixzz3v0TfhbiM
Dual Overhead Cams with Four Valves per Cylinder & Silent Cam Drive: four-valves-per-cylinder with inverted-tooth chain cam drive contributes to the smoothness and high output of the LFX. The engine incorporates a timing chain with an inverted tooth design. These smaller links engage at a lower impact speed, which decreases the noise generated. In conjunction with the smaller pitch chain, the number of teeth on the sprockets are increased, which increases the meshing frequency and further reduces noise and vibration. Four valves per cylinder and a silent chain valvetrain contribute to both smoothness and high output. Four-cam phasing changes the timing of valve operation as operating conditions such as rpm and engine load vary. Read more: http://gmauthority.com/blog/gm/gm-engines/lfx/#ixzz3v0UczULy
Composite Intake Manifold and Fully Isolated Composite Camshaft Covers: the upper intake manifold for the LFX is made from composite material and provides mass savings over an aluminum manifold, with a carefully designed structure that helps ensure quiet engine operation. The surfaces on the cam covers are shaped to limit the broadcasting of undesirable noise, and the covers use isolating perimeter gaskets, as well as isolating radial lips around the tubes that accommodate the spark plugs. These effectively de-couple the covers from vibration generated in the block and engine during combustion. Acoustic dampening has also been added for additional NVH improvements.
