Understanding Turbo Engines: How They Work, Benefits, Types, and Tips

Earlier, turbochargers were designed originally for use in aircrafts, however, they gained prominence in the 80s for being fitted in cars. Through the help of the guide below, we will get a better look into what a turbo engine is, how it works, its advantages and disadvantages, and the types included under these.

What is a Turbo Engine in a Vehicle?

Turbo engines are engines powered by a turbocharger, a device that forces extra air into the combustion chamber, thereby boosting engine power. This device is responsible for the extra boost of air, which allows fuel to burn more efficiently and thereby produces more power than a Naturally Aspirated engine of the same size.

Why are Turbo Engines Becoming Popular?

There are several reasons for the rise in popularity of turbo engines. These are:

1. Improved Performance

Provides smoother acceleration with an enhanced driving experience.

2. Increased Fuel Efficiency

Enables smaller engines to produce the same power as larger ones, without consuming more fuel.

3. Space Saving

Smaller engine sizes help reduce vehicle weight, ensuring more space and better handling.

4. Environmental Benefits

Ensures reduced emissions due to better and effective fuel efficiency.

How Turbocharged Engines Work

Turbo engines work in a simple manner:

• A turbo engine consists of two components, located within a snail-shaped housing, which includes an inlet port and an exhaust port, namely the compressor wheel and the turbine.

• Exhaust gases produced by the engine spin the turbine, which is connected to the compressor.

• The compressor forces more air into the engine intake, increasing the oxygen available for combustion.

• More air and fuel mixture results in greater power output per engine cycle.

The Role of Exhaust Gases in Turbo Operation

The exhaust gases, which would otherwise go to waste, play a crucial role in turbo engine operations, as they help power the turbine of the turbocharger, effectively recycling energy and boosting engine performance as well.

What is Turbo Lag and Why Does it Happen?

Turbo lag occurs when there is a delay between the driver pressing the accelerator and the engine’s response, i.e. the turbocharger providing the boost. It may last only up to a second, but it may prove to be uneventful for the driver. This lag may occur due to the engine not forming enough exhaust gases to spin the turbine of the turbochargers.

Today, many car manufacturers are using twin-turbo setups and superchargers to help minimise or eliminate the effects of turbo lag.

Pros and Cons of Turbo Engines

Let's have a look at the advantages and disadvantages of using a turbo engine in your car:

Pros:

• Provide better fuel economy than Naturally Aspirated (NA) engines.
• Can be fitted in both petrol and diesel engines.
• Provides better acceleration, reaching higher speeds than larger engines.
• Generate lower emissions at the same power output as larger engines.
• Produce higher torque than regular engines.
• Being smaller in size, turbo cars are lighter than regular cars.
• Engine noise is quieter due to the muffling effect, reducing the sound of exhaust gases escaping from the engine.

Cons:

• Require more maintenance to ensure optimal performance.
• It may be more complex and expensive than regular engines.
• High pressure and temperature may affect the turbocharger’s lifespan.
• Chances of turbo lag may occur, affecting the response and drivability of a car.
• More prone to breakdowns or sudden malfunctions than regular engines.
• May result in higher car insurance premiums, due to increased chances of risk.

What is a Twin-Turbo Engine and How Does it Work?

A twin-turbo engine is a car engine that makes use of a set of two turbochargers. Instead of a single one, it uses two to boost engine power, which can be either sequentially or in parallel, enhancing power delivery and reducing turbo lag.

Difference Between Turbocharged Petrol and Diesel Engines

Turbocharged Petrol Engines

It is a petrol internal combustion engine fitted to a turbocharger, focusing on driving higher power and smoother acceleration.

Turbocharged Diesel Engines

It is a diesel internal combustion engine fitted to a turbocharger, providing higher torque at lower RPMs, ideal for towing and heavy-duty use.

Turbo Engine vs. Naturally Aspirated Engine

Difference Between a Turbocharger and a Supercharger

Let us see the key differences between a supercharger and a turbocharger:

Engine Oil and Maintenance for Turbo Engines

Turbo engines require a specific kind of oil, such as higher octane fuel and premium synthetic oil, since they operate at higher temperatures and pressures, in order to protect the turbocharger and engine components.

Maintenance Tips:

• Ensure to engage in regular oil changes with recommended oil grades.
• Avoid sudden engine shutdowns after hard driving to allow turbo cooling.
• Drive smoothly and avoid excessive revving.
• Maintain recommended tire pressure and regular servicing.

What to Avoid When Driving or Maintaining a Turbo Engine:

• Avoid shutting off the engine immediately after high-speed driving.
• Do not neglect oil changes or use low-quality oil.
• Avoid aggressive driving that can overheat the turbo

Car Insurance and Turbocharged Engines

A car insurance policy is necessary to safeguard your vehicle on the road from unforeseen risks. Here's how turbocharged engines play a crucial role in impacting a car insurance policy:

• Perceived as High Risk

Insurers view cars equipped with this engine as high-risk, as they deliver high performance and acceleration, leading to higher accident risks.

• Higher Premiums

It could result in higher premiums for your car insurance policy due to the high risk associated with them.

• Modification Disclosure

If a turbocharger is added as a modification after purchase, failure to inform the insurer can lead to claim denial or policy cancellation.

Final Thoughts

For drivers looking for better fuel efficiency, performance and power—turboengines are the ideal addition to your vehicle, becoming increasingly popular in India with every passing day. But, it may have its own impact on your car insurance policy.
