Heat Shields / Shroud
Heat shield is to keep the piston ring and the bearing housing from the hot gases, and protect the piston ring from hitting by exhaust gas.
l In the old generation, heat shield was a pressed piece of stainless steel, the material quality was not good and dimensional accuracy was not high
l As updating of new generation of VNT / VGT turbo series, E&E also use better material to withstand high temperature gas.
l Twin heat shields in addition to VNT steel gasket can be provided either.
