Why You Need a Garrett Turbocharger

With the commercial vehicle market focused on continuous improvement in areas of energy efficiency and performance, there has been a renewed push to find innovative solutions in turbocharger technology to stay ahead of the game.

Garrett turbochargers offer the latest in advanced technology truck turbos, specifically designed to provide reliable, high-performance solutions that improve fuel efficiency, reduce emissions and enhance engine braking capabilities.

How does a turbocharger work?

Put simply, turbochargers use the surrounding environment to boost power to the engine. They consist of two main parts, the turbine and the compressor. The main function of the turbocharger is to use exhaust gas pressure to drive a turbine, which in turn activates a compressor.

As the compressor spins, it draws in ambient air and converts a high-velocity, low-pressure air stream into a high-pressure, low-velocity air stream. This compressed air is then pushed into the engine, allowing it to burn more fuel and consequently produce more power.

What are the benefits of a turbocharger?

The major advantage of a turbocharger is that there is no need for an external power source to function. Sometimes referred to as the “free power” device, a turbocharger does not require the engine’s power to drive it but instead utilises latent energy in the exhaust gas generated from the engine.

Through their ability to provide greater power density and increased fuel efficiency, turbochargers offer the potential to downsize to a smaller engine and maintain (or even improve) the power capabilities of a much larger engine. This reduces emissions and boosts engine efficiency and overall performance.

Why Garrett turbochargers?

When it comes to replacement truck parts, Garrett leads the industry in high performance, high-tech turbochargers. With over six decades of continuous innovation and cutting-edge developments, Garrett continues to break new ground in the advancement of turbocharging technology.

The latest offerings from Garrett promise to further enhance fuel efficiency, durability and performance:

Variable Geometry Turbo (DAVNT Turbochargers)

The latest generation of Variable Geometry Turbochargers, DAVNT (Double Axle VNT), feature two axles to support the movable vanes and improve turbine function, increasing power and torque output by reducing engine backpressure.

Wastegate/Free Floating Turbochargers

High performing, even under harsh conditions and with options suitable for a variety of engine applications, these aerodynamically-designed turbochargers maximise mechanical durability with titanium compressor wheels, special casting processes to create low-stress turbine wheels, and a unique bearing system featuring a one-piece cartridge.

Two-Stage Turbochargers

Utilised in a wide range of truck applications, from downsized 4.4L construction vehicles to heavy-duty trucks and 64L mining equipment, two-stage turbochargers are comprised of two compressors able to generate pressure four to five times higher than ambient. By splitting the compression of air, each compressor operates at increased efficiency, which improves engine performance, offers better low-speed torque, optimises fuel efficiency, and provides a longer turbo life.

Garrett is a global leader in the supply of turbochargers for Japanese trucks, and the largest supplier of original fit turbo parts for Hino, Isuzu, Fuso and UD trucks. Garrett turbochargers are also widely used as original fit technology on European and American trucks,

Garrett’s history and expertise in producing superior turbochargers extends to its commitment to spare parts for trucks, providing authorised distribution channels for aftermarket parts direct from the original manufacturer.
