Driving a car that effortlessly zooms past highway traffic is a thrill, and turbochargers make that possible. Once reserved for high-end sports cars, turbocharging in cars is now a mainstream feature in India.

But what exactly is a turbocharger, and why is it so popular? In this blog, we will explore how these powerful components work, their benefits, and essential maintenance tips to keep your turbocharged car running smoothly.

How Turbocharger Works in a Car?

A turbo is a device that takes in extra air and pushes it into the combustion chamber of an engine, so it can burn more fuel and make the car go faster. Engines without a turbo, called naturally aspirated, depend on atmospheric pressure to breathe in. Turbochargers use your exhaust gases instead.

The gases cause a turbine wheel to rotate at high RPM, which can exceed 200,000 RPM. This turbine wheel is attached to a compressor wheel by a shaft. As the turbine turns, the compressor draws in some good air, pushes it into a wheel, and throws it into the cylinders.

The reason is that since this air is denser and has more oxygen in it, the engine is going to have a much more efficient time burning fuel. This gives you a huge power boost without increasing the size of the engine block.

What are the Types of Turbochargers?

Now that you understand how turbocharging works in cars, you may ask, ‘Are there different types of turbocharging?’ The answer is yes.

Single Turbo: It is the simplest form of turbocharger as it uses only 1 turbine to compress air into the car’s engine.
Variable Geometry Turbocharger: It adjusts the vanes relative to your car’s speed, which provides much easier control of boost.
Twin Turbo: Twin turbo uses 2 miniature turbines to draw in air into the car’s engine. Usually, they are placed in parallel or in series.
Twin Scroll Turbocharger: In this kind of turbocharger, there are 2 exhaust gas inlets and 2 injection ports. It can be found in sports cars.
Electric Turbocharger: It uses an electric motor to spin the turbocharger, which reduces turbo lag.

What are the Turbocharged Engine Benefits in India?

The appeal of the turbocharged engine is that it offers a perfect mix of fuel efficiency and peppy performance. This is the reason why turbocharged cars are dominating Indian roads. Let us look at turbocharged engine benefits in India below:

Economy: Turbocharged cars require a much smaller engine to generate power similar to a larger naturally aspirated engine, which leads to lower fuel consumption in the city.
More Efficient Emission Compliance: With turbocharging in cars, vehicles can adhere to tougher BS6 and CAFE 2.0 emission standards by maximising fuel combustion and slashing overall carbon emissions.
Improved Power and Torque: Turbochargers give you more torque at significantly lower RPMs. As a result, you can overtake faster on Indian highways, drive smoothly, and conquer hilly roads without stressing the engine.
Tax Advantages: Smaller engine sizes and shorter cars, generally less than 4 m in length, result in lower excise duty levels in India. This benefit is passed on to the end consumer by the automaker, making these very affordable.

How to Maintain Turbo Car Engines in India?

Maintaining a turbocharged car in India requires regular oil changes, timely filter replacements, and proper engine warm-up habits to protect its internal components.

Turbochargers operate at extreme temperatures and high RPMs. To ensure maximum longevity and avoid expensive repairs, you must follow these crucial maintenance practices:

Maintenance Tip	What to do	Why You Should Do It
Warm up and Cool Down	Keep your car idling for 30-60 seconds after a cold start	It allows oil to circulate and lubricate the high-speed turbo engines
Use Synthetic Oil	To ensure your engine is protected, you should use high-quality synthetic oil and follow the manufacturer's instructions.	Synthetic oil can resist high temperatures and prevent carbon sludge buildup.
Fuel Quality	You should get your fuel from reputed and trusted pumps to avoid any damage.	If you use poor-quality fuel, it may cause engine knocking and put stress on your turbocharger.
Air Filter Care	If you live in a dusty area, then you should clean and replace your air filters regularly.	This will ensure that the airflow is clean and efficient and won't damage the compressor wheel.

Bottom Line

Turbocharging in cars can be the perfect mix of power, economy and green driving over Indian roads. With a bit of knowledge about how it works and some discipline with your maintenance routine, be it engine idling or timely oil changes, you can get the benefits of it.

FAQs About Turbocharging in Cars

Does a turbocharger decrease engine life?

No, turbocharging in cars does not decrease your car’s engine life if you maintain it properly.

Which oil is best for turbo cars?

Fully synthetic engine oil is highly recommended for turbo cars. It handles extreme heat better than conventional oils and provides superior lubrication. It also prevents harmful sludge buildup inside the turbocharger.

Are turbo cars more expensive to insure?

Insurance premiums depend on the car’s make, model, and engine capacity. Bajaj General Insurance offers competitive premiums and optional add-ons to fully protect your turbocharged car's engine.
