In the realm of mighty engines, turbochargers are the unsung heroes helping to revolutionize the performance of heavy-duty equipment driving power generation, marine propulsion, and mining operations.

This core technology helps original equipment manufacturers (OEMs) develop powertrains that are more fuel efficient and comply with stringent emissions regulations. It’s a world in which engineering innovation contributes to environmental progress.

Turbochargers have long been integral to automotive performance. Indeed, Garrett Motion has been at the forefront of this domain for nearly 70 years, most visibly in passenger cars, vans, trucks and motorsports. It’s fair to say that Garrett’s development of differentiated boosting solutions has helped OEMs transform everyday driving, by increasing power and efficiency while also reducing emissions.

What’s less well known perhaps is Garrett’s leadership in large off-highway engines. In fact, the very first Garrett turbo was developed for a Caterpillar D9 tractor in 1955. It was an application that marked the beginning of a turbo era that today reaches into every corner of the globe and just about every on-and-off highway automotive sector.

While passenger cars often get the headlines, turbo’s impact, in the off-highway and industrial space is just as impressive, with today’s technology helping large engines comply with challenging emissions standards in every continent.

Introducing Garrett MEG, the latest generation of large-scale turbos designed to tackle the unique demands of heavy-duty applications. Garrett’s investment in R&D across its global engineering footprint continues to deliver breakthrough advances in large turbos, including Garrett MEG, which offers enhanced performance and efficiency for industrial and off-highway engines. Garrett innovation is driving the evolution of this core enabling technology and has solutions fitting all relevant regulations, spanning from UN ECE R96 Stage IIIA, IMO Tier III, EPA & CARB Tier 4, EU Stage V, China Nonroad Stage IV and more.

A Core Technology for Off-Highway and Heavy Industry

A turbocharger harnesses energy from exhaust gases to compress intake air. By doing so, it significantly boosts an engine’s power output without increasing its displacement. This enables engines to extract more energy from each fuel molecule which, in turn, translates to higher power output. And because turbocharged engines can operate with leaner fuel-air mixtures, fuel efficiency is also improved, and corresponding greenhouse gas emissions reduced.

These benefits are sought-after in multiple heavy industries that rely on ultra-large engines. In marine, for example, turbocharged engines propel cargo ships, cruise liners, and offshore vessels, with the inherent efficiency gains helping to reduce environmental impact.

In power generation, whether in remote locations or grid-connected plants, turbos help optimize engine fuel utilization, especially during periods of peak demand. In mining or constructions, where reliability and productivity are paramount, boosted engines help provide consistent power for blasthole drills, bucket-wheel excavators, dozers, mining trucks and more.

In short, turbos are the boost behind efficiency, power and emissions reduction in many essential heavy-duty sectors, with reliance on technology growing in step with environmental commitments. So, the next time you witness a large-scale construction project, ship gliding across the ocean or a generator humming in a remote power plant, remember that behind the scenes, a turbocharger – quite possibly a Garrett – is likely hard at work, advancing progress through engineering innovation.
