Doosan Engines: Korean Power for Doosan and Develon Machines
Doosan Engines: Korean Power for Doosan and Develon Machines
The Heart of Modern Construction Machines
Doosan Infracore Engines is a South Korean manufacturer that serves as the technological heart of construction machines known first under the Doosan brand, and now as Develon. By developing its own advanced power units, the company became independent from external suppliers, ensuring a perfect synergy between the engine and the machine's hydraulics. Doosan engines are renowned for their high performance, reliability, and innovative solutions that result in lower fuel consumption.
Although the name on the machines has changed, the technology and the need for service remain the same. Our offer includes a full range of spare parts for Doosan engines that fit both machines with the Doosan logo and the latest Develon models.
History: From Licensing to Technological Powerhouse
- Foundations on Daewoo's Legacy (2005): After acquiring Daewoo's heavy machinery division, Doosan Infracore also inherited its engine production plants. Initially, the production of proven, licensed units continued.
- The Birth of In-House Technology: Doosan made a strategic decision to invest heavily in R&D to create its own unique line of engines, perfectly tailored to the characteristics of its machines.
- A Supplier to Other Brands: The success of its own designs allowed Doosan to become an engine supplier for other manufacturers. The most well-known example is Bobcat, which extensively uses compact Doosan engines in its machines.
- Evolution into Develon (2023): Although the construction machinery division was rebranded as Develon, the engine division continues its mission under the Doosan name, supplying power units to the "new" machines.
Main Doosan Engine Series
Compact Series (D18, D24, D34)
Modern 3- and 4-cylinder units designed for the compact machine market. They feature Common Rail injection and advanced aftertreatment systems.
- D18 (1.8L, 3-cyl.): Used in the smallest machines where size and fuel economy are critical.
- D24 (2.4L, 4-cyl.): An extremely popular unit powering mini-excavators and skid-steer loaders (including many Bobcat models).
- D34 (3.4L, 4-cyl.): A larger, best-in-class torque compact engine that powers larger excavators (e.g., DX140) and wheel loaders.
DL Series (DL06, DL08)
Six-cylinder "workhorses" for heavy-duty tasks, forming the heart of the most popular Doosan/Develon excavators and wheel loaders.
- DL06 (5.9L, 6-cyl.): The direct successor to the legendary Daewoo DB58 engine. Installed in extremely popular crawler (e.g., DX225, DX235, DX255) and wheeled (DX190, DX210) excavators.
- DL08 (7.6L, 6-cyl.): A larger unit powering large excavators (e.g., DX300, DX340, DX380) and loaders (e.g., DL300-DL420).
DX Series (DX12)
Engines designed for the heaviest construction machines and articulated haulers.
- DX12 (11.1L, 6-cyl.): The modern equivalent of the historic Daewoo D2366 engine. This powerful unit powers the largest excavators (e.g., DX420, DX490, DX530) and wheel loaders.
In Which Machines Do Doosan Engines Work?
Doosan engines are designed for perfect integration with their own machines. You will find them in:
- Doosan/Develon crawler and wheeled excavators (DX and Solar series).
- Doosan/Develon wheel loaders (DL and Mega series).
- Doosan/Develon articulated haulers.
- Bobcat compact machines (loaders, excavators).
- Generator sets and specialized machinery from other manufacturers.
Company Size and Market Position
Doosan is one of the world's leading manufacturers of construction machinery, and its engine division plays a key role in this strategy. Producing hundreds of thousands of engines annually for both in-house use and external customers makes Doosan Engines a significant player in the global off-road engine market.
Innovation and Future
Doosan is actively investing in the technologies of tomorrow, preparing for the industry's transformation.
- D-ECOPOWER Technology: This is an intelligent hydraulic system that precisely manages the pump and engine operation. It allows power to be used most efficiently, leading to significant fuel savings without sacrificing performance.
- Alternative Powertrains: The company is developing compact battery packs and exploring the potential of hydrogen as a fuel of the future to meet growing environmental demands.
Interesting Facts
- Korea's Oldest Company: The Doosan Group, to which the engine division belongs, is the oldest continuously operating enterprise in South Korea, founded in 1896.
- Synergy with Bobcat: Belonging to the same group for years, Doosan and Bobcat exchanged technologies. Doosan engines became the heart of many bestselling Bobcat machines, proving their quality and reliability.
Whether your machine has a Doosan or Develon logo, its heart beats to the same rhythm.
We provide professional support in selecting spare parts for Doosan D, DL, and DX series engines. Our offer includes high-quality REDX filters, turbochargers, injectors, and other components to keep your machine in top condition. Contact us!
