last week, the Doosan Infracore Engine Business Group
introduced its state-of-the-art compact diesel engine models — the D18, D24 and D34 — ranging from 1.8- to 3.4-liter displacement, and 50 to 110 hp and higher depending on configuration, for the original equipment manufacturer (OEM) market.
“With the introduction of our new compact engines, we believe Doosan is positioned to become one of the world’s top class engine makers offering the most advanced environmentally-friendly technology available,” said Dan Rim, senior vice president of sales and marketing for the Doosan Infracore Engine Business Group.
The new engines are compliant with both the stringent Tier 4 Final standards in the United States and the European Union’s Stage IIIB & IV emissions standards and will be marketed to OEM’s in the compact equipment industry. A leading producer of diesel engines since 1958, Doosan developed these compact engines to offer advanced environmentally-conscious technologies — specifically a non-diesel particulate filter (DPF) design — attractive to OEM’s because they provide advantages dealers and end-user customers want.
The Doosan compact engines are designed for a wide range of construction equipment, agricultural machinery, and material handling products among others. The company first entered the OEM market in 2012 by partnering with Bobcat Co., a member of the Doosan Infracore Construction Equipment group.
Doosan’s value proposition is well-suited for OEM’s: The Doosan compact engines have been through extensive in-machine testing with customers in real working conditions; Doosan has an extensive history in engine manufacturing, and for compact engine development, they’ve partnered with credible industry engine development consulting firms; Doosan as an organization has a strong foundation and added experience in construction and industrial product manufacturing — the compact engines were developed in collaboration with top engineers from other Doosan brands, and strict manufacturing guidelines of those brands match up well with the Engine Business Group’s own standards.
For more than 50 years, Doosan Infracore has steadily leveraged its research and development capabilities and production technologies in Korea and beyond. Focused business expansion has allowed the Engine Business Group to become a global leader in supplying diverse customers with diesel and compressed natural gas engines, and it now operates facilities for engine assembly, materials production and parts processing. In addition to construction equipment, the Doosan Infracore Engine Business Group product portfolio has grown to include a strong presence in a wide range of engine markets including forklifts, generator sets, buses and trucks, marine and military hardware.
The D18, D24 and D34 engine models also allow for simple installation and configuration to fit almost any type of equipment. Created with exemplary fuel efficiency and a maintenance-free aftertreatment system, Doosan compact diesel engines offer lower total cost of ownership over the total life of the engine. Customers can expect faster payback periods with Doosan compact engines compared to any other engine in this class.
Typically, compact engine manufacturers apply a diesel particulate filter (DPF) to their after-treatment systems with the goal of lowering emissions and addressing growing environmental concerns; however, the D18, D24 and D34 models use an innovative after-treatment system that eliminates a DPF, reducing inconvenience and maintenance for the customer. A non-DPF engine design provides a simpler design; prevents the need for a larger mounting space; eliminates ash cleaning; enhances fuel economy; eliminates risk of thermal damage and reduces service claims.
Doosan achieved the non-DPF solution by designing an ultra-low particulate combustion (ULPC) engine. The ULPC is accomplished through a specially designed engine combustion chamber that significantly reduces the amounts of particulate matter created during combustion. Therefore, Tier 4 final and Stage IIIB & IV emissions compliance can be achieved without the need for a DPF.
