2017 Chevrolet Silverado HD Arrives With Segment First Jet Drain Oil Separator0
If we only had a few words to describe the 6.6-liter L5P Duramax turbo-diesel V8 engine, we would choose the following: it’s all new.
However, in an effort to ease digestion, we’ll continue to break up the newest of new components surrounding the 6.6L L5P V8 Duramax engine, found in the 2017 Chevrolet Silverado HD and 2017 GMC Sierra HD.
We’ve already covered its increased power ratings of 445 hp and 910 lb-ft of torque and also took a deep dive into how it burns cleaner despite increased power. Now, let’s look at a segment first: the venturi jet drain oil separator.
As stated, the 2017 Silverado HD and 2017 Sierra HD are the first in the segment to employ this system. The venturi jet drain oil separator is tasked with ensuring oil control in under full-load operation.
The sealed system works by collecting the fine mist of oil given off by the blow-by gas. It then uses a small portion of the boosted air via the turbocharger to pump the collected oil back into engine oil sump for reuse by the engine.
In other systems, oil is not able to return to the oil sump for reuse. This can result in oil carryover into the cylinders during combustion.
