Turbocharger Structure

A turbocharger consists of a compressor wheel and exhaust gas turbine wheel coupled together by a solid shaft and that is used to boost the intake air pressure of an internal combustion engine. The exhaust gas turbine extracts energy from the exhaust gas and uses it to drive the compressor and overcome friction.

Here is the details of the essential parts of a turbo system,

1, Turbine: The turbine converts the energy from the engine’s exhaust gases into rotational force. It comprises two primary parts: the turbine wheel and the turbine housing. The gases cause the turbine wheel to spin, connected to the compressor via a shared shaft.
2, Compressor: The compressor is tasked with increasing the pressure of air entering the engine. It consists of a compressor wheel and a compressor housing. The spinning turbine causes the compressor wheel to rotate, thereby pulling in and compressing air.
3, Center Housing: This central part houses the shaft that connects the turbine and compressor. It also accommodates the bearing system and provides the turbocharger’s necessary lubrication and cooling mechanisms.
4, Wastegate: Fitted to the turbocharger’s exhaust side, the wastegate regulates exhaust gas flow to the turbine. By controlling the speed of the turbine, the wastegate helps manage the amount of boost pressure.
5, Actuator: The actuator controls the opening and closing of the wastegate and is typically driven by pressure differentials in the system.
6, Intercooler: Although not a part of the turbocharger itself, the intercooler is an integral component in a turbocharged system.

Turbocharger Materials

Turbochargers are constructed with high quality materials with mechanical strength and thermal resistance to withstand high rotational speeds, extreme temperatures, and pressure differentials. Here are some of the commonly used materials:

1, Turbine Housing and Wheel: The turbine housing and wheel must endure the highest temperatures in a turbocharger. They are typically made from high nickel-content cast iron, such as ductile iron, to resist thermal fatigue and oxidation. In some high-performance applications, stainless steel or even Inconel, a type of superalloy, may be used for their superior heat resistance.
2, Compressor Housing: The compressor housing usually experiences less extreme temperatures. As such, it is often made from lighter materials like aluminium or plastic to reduce weight and improve overall engine efficiency.
3, Bearing Housing: The bearing housing supports the turbine and compressor and is generally made from cast iron or aluminium. It also incorporates lubrication and cooling channels to maintain optimal operation conditions.
4, Shafts and Bearings: Shafts and bearings are subjected to high loads and rotational speeds. They’re typically crafted from high-strength steel or alloyed steel. Bearings may also be composed of materials like bronze or brass.
