What is a Turbocharger? 6 Reasons Why They are Used!

Wondering what is a turbocharger and why is it used?

A new turbocharger is essentially a power booster for your vehicle. It enhances performance without requiring a larger engine. 

Many drivers do not fully understand the technology behind turbochargers. This is the reason why they are unable to reap its full benefits. 

This guide will explain what a turbocharger is and how it works. More importantly, we’ll focus on its benefits, reasons why modern-day cars use them, and how to choose a turbocharger.

So, without any further ado, let’s get started! 

What is a Turbocharger? How Does it Work?

A turbocharger is a mechanical device attached to your vehicle’s engine with the purpose of enhancing its performance. 

Now, as you’re aware, internal combustion engines work on a mixture of air and fuel.  The temperature of this mixture is risen to a point where it combusts. 

Usually, this temperature rise takes place via compression inside engine cylinders. 

But what if there was a way to pre-charge the incoming air? Wouldn’t it make combustion much easier? Since the incoming mixture is already at a high temperature.

This is exactly what a turbocharger does. 

It increases the temperature of incoming air entering the engine cylinders. Now, when this hot air is mixed with the fuel, the mixture’s temperature is already high.

The engine needs to do less work to compress the mixture and ignite it. This is how even a smaller engine can generate more power.

One might ask, where does the heat that increases the air temperature come from? 

That’s the best part about turbochargers. They utilise the exhaust heat that would go out into the atmosphere. Hence, a turbocharger allows vehicles to balance power and efficiency. 

They enable the engine to produce more power while consuming less fuel. This makes a turbocharged engine a practical solution for all modern-day cars.

Therefore, rather than being an add-on for high-performance vehicles, turbochargers are now standard in many cars and vans. 

6 Reasons Why Turbochargers are Used in Modern Vehicles

Turbochargers were once mainly associated with sports cars and high-speed vehicles. Today, however, they’re also included in regular cars and vans. This is because they allow average drivers to benefit from fuel efficiency and a well-balanced drive. 

Here are the top 6 reasons why turbochargers are becoming increasingly popular:

1. Better Fuel Efficiency

Turbochargers help you save on fuel costs by enhancing efficiency. They enable smaller engines to deliver the same power as larger ones. Moreover, they utilise exhaust heat from your engine, which would go to waste.

Both of these reasons allow turbocharged engines to reduce fuel consumption. Many modern cars with turbo engines achieve impressive miles per gallon (MPG) ratings. 

In fact, a turbocharged engine can achieve up to 20% better fuel economy than its naturally aspirated counterpart. 

As fuel prices increase, owning a turbocharged vehicle is more advantageous for you!

2. Compact Engine Design

One of the most significant advantages of turbocharging is the ability to use smaller engine sizes. By utilising a turbocharger, manufacturers can replace larger engines with smaller ones that offer comparable power outputs.  This design reduces the overall weight, which can also improve the vehicle’s agility and handling.

Smaller engines also mean less material usage during manufacturing, contributing to lower production costs.

3. Lower Emissions

Turbochargers help manufacturers meet stringent emission regulations without sacrificing performance. The ability to generate power from smaller engines means less fuel is burned.

Moreover, turbocharged engines often work alongside systems like the EGR (Exhaust Gas Recirculation) valve, which helps reduce nitrogen oxide emissions by recirculating a portion of exhaust gases back into the engine. Together, this setup leads to lower carbon dioxide and other harmful emissions being released into the atmosphere.

So, turbocharges not only save money but also contribute to environmental sustainability by reducing your carbon footprint. 

4. Increased Power Output

An obvious benefit of turbochargers is that why they boost your car’s power output. For instance, a turbocharged four-cylinder can equal the power output of a six-cylinder naturally aspirated engine. This increased power enhances your driving experience significantly.

5. Improved Acceleration

With more power comes better acceleration. Turbochargers provide an immediate boost of power when you press the accelerator pedal. This results in quicker acceleration times compared to naturally aspirated engines.

You’ll notice this enhanced responsiveness during daily driving tasks like merging onto highways or navigating city traffic. Turbocharged engines deliver more torque at lower RPMs, making them feel lively and engaging.

6. Better Altitude Performance 

Driving at high altitudes is tough in cars with naturally aspirated engines. However, cars with turbochargers excel in these conditions due to higher power output.

Even at elevated altitudes, your turbocharged vehicle maintains optimal performance levels. You won’t experience the significant loss of power that typically affects non-turbo engines.

Many mountain drivers prefer turbocharged vehicles for this very reason. They can confidently tackle steep inclines without worrying about engine performance degradation.

Final Thoughts: What is a Turbocharger?

Turbochargers have become an essential feature in modern vehicles. They offer a practical solution for drivers who want efficiency without compromising quality. In short, it is a small addition with a big impact on your driving experience.

Whether you’re driving to work or taking the family out, a turbocharger helps keep fuel costs manageable. It does so while delivering a reliable performance that meets everyday needs. 

If you’re considering a turbocharged vehicle, it’s also important to understand how to choose a turbocharger that suits your car’s engine size and performance requirements. The right turbocharger can enhance your vehicle’s power while ensuring optimal efficiency.

Therefore, you should always choose a car with right turbocharger. When selling a car, one with a right turbocharger might fetch you more money.
