Turbocharger CHRA [Center Section]
and Model first.
The Turbocharger CHRA which stands Center Hub Rotating Assembly is the component that incorporates the shaft that connects the compressor and the turbine. The CHRA also houses a bearing system to support the rotating shaft with minimal fiction. This is usually a ball-bearing or thrust-bearing system. A constant flow of pressurized engine oil keeps the bearings lubricated. The ball-bearing system is more efficient than a thrust-bearing system as it generates less heat and uses less engine oil. They are designed to handle high speeds and also reduce turbo lag.
The CHRA also implements a cooling system to remove the heat generated within the turbocharger. It can be air-cooled or water-cooled. A water-cooled CHRA has an inlet and outlet for the coolant to circulate inside the assembly. The coolant keeps the lubricating oil thick and cool, and prevents the engine oil from coking, a destructive distillation process that leaves a layer of carbon deposits in the housing assembly. Due to the high temperatures generated within the turbo unit, oil coking is one of the common causes of turbo failure.
Other causes include coolant and oil leaks, both of which can affect the efficiency of your turbocharger. The shaft that connects the impeller and turbine can also become faulty or damaged due to improper balancing, inadequate lubrication or excessive overheating. If you notice that your engine's performance is lower than normal or if your exhaust smoke is black or has a trace blue in it, it's a possibility that the CHRA is at the root of the problem. You should replace any defective part of your Turbocharger CHRA at the earliest to avoid any possible damage to your engine and your turbocharger.
