Engines

Doosan Infracore

For more than 50 years, Doosan has been building industrial engines that stand out for their durability, reliability and quality.

The portfolio is constantly being expanded, most recently in the compact engine segment with displacements of between 1.8 and 3.4 liters. They are used wherever robustness, reliability and maximum economy are required – with or without a diesel particulate filter (DPF). The low-emission diesels for industrial applications meet the most stringent environmental and ecological requirements of the extremely strictly regulated markets in North America and Europe.

Doosan Infracore manufactures diesel engines for industrial applications and agricultural machinery as well as for generators or marine applications with displacements between 1 and 22 liters. The modern super-compact engines of the G2 series meet the latest exhaust emission standard of the American TIER 4 Final as well as the European regulations according to stage 3B or stage IV and stage V.

In addition, Doosan diesel engines will be available as ready-to-run hybrid units in the very near future.
