How Does A Turbocharger Work?

Traditionally, the car’s power was dependent upon the size and number of cylinders. Nowadays, turbochargers, compressors, and electronic engine control are responsible for overall performance. This is acquired by recovering the waste energy of the exhaust and feeding it back into the engine’s intake, ensuring better fuel efficiency before getting vented at the beginning of the exhaust stage.

A turbocharger is a vehicle engine device engineered to boost overall efficiency and performance. This is one of the significant reasons why most auto manufacturers opt to turbocharge their vehicles. Even some of the latest car models are equipped with turbocharged engines or constitute a popular choice of aftermarket product for most car enthusiasts. 

The Structure of a Turbocharger

A turbocharger comprises a turbine and a compressor, joined together by a shaft. The turbine further consists of a turbine wheel and a turbine housing that directs the exhaust gasses to the former component. The compression gives the engine additional power and efficiency, offering better airflow in the combustion chamber and more fuel to the engine for extra strength. 

The compressor also consists of two main parts: wheel and housing. The compressor’s action mode is contrary to the turbine’s functioning. Meaning: The compressor wheel is attached to the turbine with a forged steel shaft. So, when the turbine spins the compressor wheel, the high velocity draws the air inside and compresses it. The compressor further transforms the high-velocity, low-pressure air flow into a high-pressure, low-velocity airflow via the process of diffusion. The compressed air is then pushed into the engine, enabling it to burn additional fuel to produce greater power. 

What Supports the Functioning of a Turbocharger?

Ideally, four parts support the working of a turbocharger. These include


The manufacturing of a turbocharger features an air intake, two different impellers (a compressor towards the front and a turbine in the rear), and a charged air exhaust that connects to the intercooler. 


An intercooler or a secondary radiator is equipped to lower the temperature of the charged air forced out of your vehicle’s turbocharger. It is engineered to intercept the air before it reaches the engine and uses coolant as a chilling agent for your car.  


The valve between the turbocharger and the exhaust intake is a wastegate. It bypasses the turbine to further control the boost pressure of your vehicle. 

ECU Tune

The electronic brainpower of a turbocharged engine requires different calibrations for fuel-to-air mixture and ignition timing compared to vehicles with a naturally aspirated engine. For instance, if someone installs a turbocharger in a car that was not programmed to have one, they will have to reprogram their engine’s electronic control unit (ECU) to ensure its proper and smooth functioning. 

Greater airflow, increased power and efficiency, and better emissions all contribute as significant perks of installing a turbocharger to your vehicle’s engine. So, what are you waiting for? Consider getting a turbocharger installed in your car with the assistance of a reputed aftermarket car product dealer in town to ensure quality products and reliable services.
