The Importance of Turbochargers

Historically, the power of a car's engine was dependent on the number and size of cylinders. But  today, electronic engine control, turbochargers or compressors are responsible for the overall performance. The turbocharger has a particularly important role it was used to considerably increase engine power. And why a turbocharger is so important to cars, here are three reasons.

1. Electrochemical Benefits

Given these conditions, the production of turbochargers can definitely be classified as one of the most demanding tasks in automotive production. This applies to both the complex housing and the turbine shaft. These components are manufactured from high-performance materials that can easily withstand temperatures of up to 1,000 degrees Celsius such as heat-resistant cast steels or Inconel alloys. There is no thermal damage to the material and tool wear is minimal even with the hardest of materials—these are major advantages over conventional machining techniques. After all, inconel and similar materials are responsible for shorter tool lives.

2. Increasingly Important

The fact that the production of turbochargers is becoming increasingly demanding has a lot to do with the major downsizing trend in the automotive industry. The displacement of many combustion engines is shrinking, while turbocharger compression ensures constant, or even increasing performance. Interestingly, downsized engines are even heavier than similar engines without a downsized design due to the additional weight of the turbocharger and intercooler. To decrease overall weight, developers are moving toward reducing the thickness of the housing wall, which puts more demand on conventional machining.

3. Future Challenges

Turbocharging continues to be a key technology for the development of economical and efficient engines. However, various technological trends present new challenges. For example, systems that are part of the exhaust gases are cooled, mixed with the charge air and recirculated into the engine are more frequently being implemented. This exhaust gas recirculation (EGR) is one of the major solutions implemented to reduce diesel engine emissions. As a result, the turbocharger must press more air into the combustion chamber in order to supply it with a sufficient amount of oxygen. Many manufacturers are relying on two-stage charging, which involves two different turbochargers.
