Turbochargers are one of the most important components in modern engines. Industrial turbochargers work by compressing air and forcing it into the engine’s combustion chamber, allowing for more efficient burning of fuel and a higher output of power. But how does this all happen?

Let’s take an in-depth look at the anatomy of a napier turbocharger.

The core components of napier turbo chargers

A napier turbocharger is made up of several different components, all working together to increase performance and efficiency. It’s main three parts are the turbine, the compressor, and the bearing system. Let’s look at each of these…

The Turbocharger Compressor

The napier turbocharger compressor is made up of 2 main components, the compressor wheel and compressor cover. The turbine wheel draws in exhaust gases from your engine, while the compressor wheel pumps air into your engine’s intake manifold. Its job is to compress the air that enters your engine to increase its efficiency by increasing its power output without consuming extra fuel in the process.

The Turbine

Considered as the heart of the napier turbo, the turbine works to extract energy from the exhaust in order to turn the compressor wheel, which then supplies air to the engine. It is made up of two core components, which are the shaft assembly and the turbine housing.

The industrial turbine housing contains the turbine wheel which is connected to the engine’s exhaust manifold through a series of pipes or hoses. As exhaust gasses travel through the turbine housing they pass over the napier turbine wheel causing it to spin at high speed. This spinning wheel then drives the compressor wheel via a shaft, allowing for more air to be pushed into the engine’s combustion chamber. This increased air pressure helps to create a much more efficient burn, thus creating more power for the engine.

The Bearing System

The turbo bearing system is important as it is supports the turbine shaft, connecting the turbine and compressor wheels together. It must allow for high rotational speeds, withstand shaft motion gyrations, handle radial, axel and thrust loads, survive high temperatures and contain enough embeddability of contaminates to keep the turbo from failing prematurely. So, all parts within the bearing system need to be of the highest quality to reduce the risk of a breakdown and to optimise turbocharger performance.
