What Is A Turbocharger : Location, Types, Parts and Working

what is turbocharger

At present, turbochargers are being used in the engines of most modern vehicles, so that the engine performance can be further improved and more power can be obtained.

Turbocharger is a main part used in modern engines, which helps in increasing the power of the engine so that the vehicle engine can provide better power and performance in every condition.

So, you should know what is a turbocharger and how does it work? Besides, you also need to know why turbocharger is necessary and what effect it has on the performance of the engine?

What Is A Turbocharger?

A turbocharger is an engine component that increases the velocity and volume of air to efficiently ignite fuel combustion in modern engines.The engine’s exhaust gases rotate the turbocharger’s turbine at high velocity, causing the turbocharger’s turbine to push air into the internal combustion chamber at high speed and pressure.

The increased airflow into the internal combustion chamber of a turbocharged engine ignites the fuel more easily, and the engine provides more power and better efficiency.

At present, turbochargers are being used in both diesel and gasoline-powered engines, as turbochargers help increase the power of the engine.

How Does A Turbocharger Work?

A modern engine is equipped with a turbocharger, whose turbine is connected to the compressor wheel. The turbine rotates due to the flow of exhaust gases of the engine. The turbocharger’s turbine is located in the exhaust flow of the engine and converts the exhaust gases into mechanical energy to rotate the turbine wheel.

The compressor wheel in the turbocharger is located on the side of the air intake system, where with the help of the compressor the turbocharger draws outside air and injects it into the engine with high pressure.

When the engine is running, the exhaust gases from the engine flow through the turbine housing of the turbocharger.

These exhaust gases pass through the turbocharger’s turbine wheel, causing the turbocharger’s turbine to rotate, and are transmitted through the turbocharger’s shaft to the compressor wheel located at the other end.

The turbocharger’s compressor wheel draws in outside air more quickly than the inlet air, and the turbocharger compresses the air before it goes into the air intake manifold.

This compressed air contains more oxygen and is denser. The turbocharger injects compressed air into the internal combustion chamber of the engine. This speeds up the process of burning fuel in the internal combustion chamber of the engine. Which provides more power to the engine.

Wastegate and bypass valve are two important components of a turbocharger. The wastegate is a valve that controls the amount of exhaust gases flowing through the turbine wheel and increases pressure.

When boost pressure exceeds a certain level, a bypass valve is used to release the compressed air, preventing over-boosting and potentially damaging the engine.

Where Is The Turbocharger Located?

However, the location of the turbocharger may vary depending on the engine model. But in most engines the turbocharger is usually located between the engine and the exhaust manifold. However it is mounted on the top or side of the engine.

Types Of Turbochargers

  • Single Turbo
  • Twin Turbo
  • Twin Scroll Turbo
  • Variable Geometry Turbo
  • Variable Twin Scroll Turbo
  • Electric Turbo

Parts Of Turbocharger

There are six parts to a turbocharger used in a vehicle’s engine. These parts are as follows:

1. Compressor Wheel

The compressor wheel is an important part of the turbocharger, which compresses the air entering the engine and compresses it into the internal combustion chamber of the engine, thereby accelerating the process of fuel combustion in the internal combustion chamber.

2. Turbine Wheel

In a turbocharger, the turbine wheel is driven by the exhaust gases of the engine, when the exhaust gases of the engine pass through the center of the turbine. It then rotates, and the turbine drives the compressor wheel of the turbocharger.

3. Center Housing

One part of the turbocharger is the center housing. This part connects the compressor wheel and turbine wheel of the turbocharger. The main shaft and bearings are located in this housing.

4. Actuator

The actuator part of a turbocharger controls the amount of boost from the turbocharger by adjusting the position of the wastegate, due to which the engine provides more power when the engine is accelerated. The actuator works on the principle of vacuum.

5. Westgate

A wastegate is a type of valve in a turbocharger that controls the exhaust gases flowing through the turbine wheel of the turbocharger, due to which the turbocharger can work successfully.

6. Fluid & Coolant Lines

Fluid is that part of the turbocharger by which the shaft and bearings of the turbocharger are lubricated, due to which the compressor wheel and turbine wheel of the turbocharger rotate smoothly without friction or overheating.

FAQ’s

Here are some FAQs related to turbochargers, which will help in making this article helpful content for the users.

What Are The 3 Main Parts of A Turbocharger?

Actually, there are many parts of turbocharger. But a turbocharger has three main parts. Turbine wheel, compressor wheel, shaft and bearing.

What Controls Turbo Pressure?

The turbo pressure is controlled by the actuator and wastegate, due to which the turbocharger works successfully.

What Causes Turbo Failure?

The cause of any turbocharger failure is lack of lubrication in the internal parts. Because the shaft of the turbocharger works on the basis of lubrication. But due to lack of lubrication, the shafts wear out, become loose or seized, due to which the compressor or turbine wheel stops spining.
