What exactly is a turbocharger for cars and what does it do? Here’s to learn a little more about the same!
Turbochargers are specific car components that are used to boost vehicle performance by pumping fresh air into the engine, with the gases coming out of it. They were invented by Alfred Bucci in the year 1905 and have since evolved into a standard engine component. The mechanisms for a turbocharger are fairly simple being composed of a compressor and a turbine. The exhaust gases have an outlet, which spins the turbine and serves as a suction pump for fresh air from the outside.
When the engine runs, exhaust gases are tapped from the exhaust and brought within the turbocharger. They help to rotate the turbine wheel attached to the compressor. This in turn sucks the fresh air in. Air moves through the intake and into the engine. However, sucking up air means that its temperature rises with compression. Therefore, cars have another component known as an intercooler. The blow-off valve is connected to the inlet manifold while making that signature whooshing Sound with excessive air sucked in the same. wastegate The exhaust is the part attached to the manifold and helps to expel excess gases. It also creates what . is referred to as turbo whistle or turbo flutter,
Advantages of Turbocharger
- The main job is to improve power delivery and performance.
- Another advantage is better efficiency if the car is driven carefully.
- A turbocharger helps in smaller engines especially the 1.0 liter mills that would have been sluggish otherwise.
However, there are some challenges worth noting. Turbo lag is one such issue—it means extra wait time while more power is created. The power band is at times too narrow, hindering the overall boost time as well. There are a variety of turbochargers available with the cars as well. These include twin-scroll turbo as well as twin and single turbo units. Then there is the variable Twin Scroll Turbo which is a rare but one of the most advanced options, which works on VGT principle but offers better performance at an affordable manufacturing cost.

Variable Geometry Turbo (VGT) is known for a single-turbo system with vanes within the unit that helps control airflow and spinning the turbine. This results in better delivery of power as well as higher efficiency overall. An electric turbo is another type of unit that is a state-of-the-art system to use. This solves various issues including excessive heat and overall turbo lag. No more power delays or inefficiency issues. With the electric motor attached to the turbine, the turbo unit spools rapidly, increasing overall effectiveness.
