A turbocharger is an extremely precise mechanical device designed to increase engine power by efficiently compressing and supplying air to the cylinders. Although a turbocharger may appear to be a single component at first glance, it consists of many complex, high-precision parts that operate under extreme conditions – high pressure, high temperature, and immense loads. In this article, we will take a detailed look at all the main turbocharger parts, their functions, prices, and the most well-known manufacturers.

Main Turbocharger Components

Each turbocharger consists of several main assemblies: the compressor side, the turbine side, and the central housing (CHRA – Center Housing Rotating Assembly). Each of these components has its own important function, ensuring smooth turbocharger operation.

1. Compressor Side

The compressor side is responsible for compressing air and supplying it to the engine. It consists of the following main parts:

2. Turbine Side

The turbine side is responsible for converting exhaust gas energy into mechanical energy, which spins the compressor.

3. Central Housing (CHRA – Center Housing Rotating Assembly)

The CHRA is the main part of the turbocharger, connecting the compressor and turbine sides. It contains bearings and the lubrication system.

How Much Do Turbocharger Parts Cost?

The prices of turbocharger parts depend on the manufacturer, materials, and technological solutions. Here are some examples:

Most Well-Known Turbocharger Manufacturers

There are several major turbocharger manufacturers worldwide that supply parts to both automakers and the aftermarket:

A turbocharger is a complex, high-precision mechanism where each part plays an important role. To ensure long-term operation, it is important to use high-quality components and choose reliable manufacturers. Properly maintained turbochargers can last hundreds of thousands of kilometers and ensure maximum engine efficiency.
