DOOSAN DP126 Series
For Power Generation
Doosan Infracore, which has been engaged in engine production and development since 1958, introduces a new generator engine.
The newly introduced DP126 Series has been born with the two years of effort from Doosan Infracore, the company
with excellent track record of designing superb engine design techniques.
When compared to other engines in its class, which are manufactured by competitors, it displays a higher output, excellent fuel efficiency,
higher safety, and easier maintenance and is expected to become the key product from Doosan Infracore.
