This core technology helps OEMs develop powertrains that are more fuel-efficient and meet stringent emissions regulations. This is a world where engineering innovation drives environmental progress.

Turbochargers have long been a critical component of automotive performance. In fact, Garrett has been a leader in this field for nearly 70 years, especially in passenger cars, vans, trucks and racing. It can be said that Garrett’s differentiated boosting solutions have helped OEMs transform daily driving, increasing power and efficiency while reducing emissions.

Perhaps less well known, Garrett is also a leader in large off-road engines. Garrett’s first turbocharger was developed for the Caterpillar D9 tractor in 1955, marking the beginning of the turbocharger era. Today, turbocharging technology is used around the world, covering nearly all on-road and off-road vehicle applications.

While passenger cars always get the spotlight, the impact of turbochargers in the off-road and industrial sectors is equally impressive. Today, this technology helps large engines meet stringent emissions standards on every continent.

Garrett’s global engineering R&D investment continues to drive breakthroughs in large turbochargers. Garrett’s innovations advance this core technology and provide solutions for all relevant regulations, including UN ECE R96 Stage IIIA, IMO Tier III, EPA & CARB Tier 4, EU Stage V, China Nonroad Stage IV, and more.

Core Technology for Non-Road and Heavy Industry

Turbochargers use the energy in the exhaust gases to compress the intake air. This allows the engine’s power output to be significantly increased without increasing displacement. This enables the engine to extract more energy from each fuel molecule, which translates into higher power output. In addition, because turbocharged engines can use a leaner fuel-air mixture, they also improve fuel efficiency and reduce greenhouse gas emissions.

Turbochargers used to be mainly associated with sports cars and fast vehicles. However, today they are also found in regular cars and vans. This is because they allow the average driver to enjoy fuel efficiency and a balanced driving experience.

Here are six reasons why turbochargers are becoming increasingly popular:

1. Improved Fuel Efficiency

Turbochargers help you save on fuel costs by increasing efficiency. They enable smaller engines to deliver the same power as larger engines. Additionally, they utilize waste heat generated by the engine that would otherwise be wasted.

These two reasons allow turbocharged engines to reduce fuel consumption. Many modern cars with turbocharged engines achieve impressive miles per gallon (MPG) ratings.

In fact, turbocharged engines can achieve up to 20% better fuel economy than naturally aspirated engines.

With fuel prices rising, owning a turbocharged car is even better for you!

2. Compact Engine Design

One of the most significant advantages of turbocharging is the ability to use smaller engines. By using turbochargers, manufacturers can replace large engines with smaller engines that have comparable power output. This design reduces overall weight and can also improve the vehicle’s agility and handling.

Smaller engine size also means less material is used during manufacturing, which helps reduce production costs.

3. Reduced emissions

Turbochargers help manufacturers meet strict emissions regulations without compromising performance. Being able to generate power from a smaller engine means burning less fuel.

In addition, turbocharged engines can also utilize exhaust gases, thereby reducing the amount of carbon dioxide and other harmful substances emitted into the atmosphere.

Therefore, turbocharging not only saves money, but also promotes environmental sustainability by reducing carbon footprint.

4. Increased power output

One obvious advantage of turbochargers is that they can increase the power output of a car. For example, the power output of a turbocharged four-cylinder engine is comparable to that of a six-cylinder naturally aspirated engine. This increased power can significantly improve your driving experience.

5. Improved acceleration performance

The more power, the better the acceleration performance. When you step on the accelerator pedal, the turbocharger can immediately increase the power. This can shorten the acceleration time compared to a naturally aspirated engine.

You’ll notice this enhanced responsiveness in everyday driving tasks, such as merging onto the highway or driving in city traffic. Turbocharged engines offer more torque at lower rpm, making them feel lively and fun.

6. Better high-altitude performance

Cars with naturally aspirated engines have a very difficult time driving at high altitudes. However, turbocharged cars perform better at high altitudes due to their higher power output.

Even at high altitudes, your turbocharged car will maintain optimal performance levels. You won’t experience the drastic loss of power that you would normally experience with a non-turbocharged engine.

Many mountain drivers prefer turbocharged vehicles for this very reason. They can confidently tackle steep slopes without having to worry about a drop in engine performance.
