Turbocharger Cooling And Lubrication

WARNING: This page is about a different variant/trim than selected.

The turbocharger is connected to the engine oil circuit for lubrication and cooling purposes.

The pressurized engine oil for the turbocharger is supplied directly from the oil filter assembly.

The rapid acceleration and deceleration response demands of the turbocharger rely greatly on a steady flow of clean oil. The oil supplied from the engine's lubrication system provides lubrication to the turbocharger's spindle and bearings. It is also acting as a coolant for the turbocharger bearing housing.

For the turbocharger to remain durable, it is essential that the oil has a free-flow through the turbocharger and unrestricted return to the engine's oil pan. It is therefore imperative that the engine oil is replaced at regular service intervals with the recommended quality and quantity of oil.

The Low Pressure (LP) turbocharger compressor features a Water Cooled Compressor Cover (WCCC). The WCCC is allowing an increased charge air temperature compared to the lower output engine whilst mitigating oil coking within the compressor.
