    Doosan Infracore’s CNG engines applied Selective Catalytic Reduction(SCR) technology in order to comply with Euro 6, the latest emissions requirement. The high efficienct engines also remarkably lowered the total cost of ownership.

    Doosan Infracore began development of a natural gas engine in 1995. With rich experiences in diesel engine development, euro 3 natural gas engine was born and began mass production in 1999. Since then, Doosan natural gas engines are supplied all over the world powering diverse kind of commercial vehicles. Now 2014, Euro 6 compliant natural gas engines are supplied all over the world powering. What are benefits of a natural gas engine? It’s more environmental-friendly and emissions are much lower than other fuel engines. It offers lower total cost of owner ship with high fuel efficiency and low price of natural gas. Then does a natural gas engine compromise performance? Absolutely No. Vibration and noise are much lower than diesel engine. Power output of a natural gas engine is the same or better than a diesel engine. Doosan Infracore has 2 models of natural gas engine; 8.1 liter GL08 and 11.1 liter GL11. All of Doosan Infracore natural gas engines meet Euro 6 emissions regulation. Doosan natural gas engines have Oxidation Catalyst and Selective Catalytic Reduction to meet euro 6 regulation. What are benefits of SCR? Three words. It saves cost. It delivers better fuel efficiency and consumes less engine oil than an EGR equipped engine. SCR Muffler doesn’t need to be replaced until the end of life engine. SCR simply adds a Diesel Exhaust Fluid (DEF) into the exhaust gas and filters it through a catalyst to convert NOx into nitrogen and water, and then it is released into the air. Doosan Infracore euro 6 natural gas engines have on board diagnostics system. OBD can monitor an overall performance of engines and aftertreatment system. Doosan Infracore natural gas engines It provides the best solutions for our environment and people.

    The generator diesel engine is greatly enhanced in power, quality, durability and maintenance, reflecting the voice of customers.

    Doosan Infracore started building Korea’s first diesel engines in 1958 and has been expanding its business ever since. Today, Doosan Infracore manufactures diesel engines and natural gas engines for buses and trucks, industrial purposes, power generation, and marine engines and supply them to all over the world. Now, Doosan Infracore introduces new engine, DP series for generator sets developed based on over 50 years of engineering expertise to satisfy the customer. DP Series engines evolved in every aspects Performance Design Convenince DP Series engines deliver all of this by improving and upgrading the existing engines to satisfy customer. New DP Series engines is getting stronger. Power output is increased by more than 20% comparing the current models but offers in smaller size and maintains mechanical type which contributes to handling and operating engines more easily. DP Series consists of in-line and V type engines offering power range between 86 kW and 828 kW. DP Series engines consume noticeably lower fuel. As all DP Series engines have higher power output than existing models, users can use new DP Series 10 cylinder V type engines instead of previous 12 cylinder V type engines. Both new 10 cylinder and previous 12 cylinder offers the same range of power output but new DP Series engines are in smaller package and consume less fuel. DP Series engines are designed to allow easy maintenance and ease of convenience. DP Series engines obtain the maximum power output and fuel efficiency while maintaining mechanical type that helps customers manage an engine more easily and conveniently. The brand new engines are designed to be in more compact package which resulting in easier engine installation and maintenance. DP Series engines are easy to install into generator sets. A hanging of engines are much easier and an installation of an alternator are simpler than before. In addition, smaller size but high power output engines can secure the larger space in generator sets DP Series engines of durability is strengthened. Among thousands parts of an engine, there are 5C, the most important parts of an engine. 4 parts of 5Cs are reinforced to improve durability. Cylinder Head Cylinder Block Crankshaft Connecting Rod & Piston Ring Rigidity of these major parts is improved by minimizing stress concentration and increasing fatigue strength. DP Series engines have high performance radiators. Intercooler is redesigned and material is changed. The ability of cooling down the heat generated by engine combustion is improved.

  • Casting Manufacturing Process Video (Cylinder Block and Head)

    Doosan Infracore Engine Video

    All of Doosan Infracore’s engines are equipped with cylinder blocks and heads which are produced in-house.

    Doosan Infracore has manufacturing plants building engines and metal castings Engine manufacturing plants cover 38,300m2 and a casting manufacturing plant covers 20,000 m2. Doosan builds 55,000 tons of castings a year. All Doosan Infracore engines have its own built cylinder blocks and cylinder heads. In 1975, Korea’s first casting manufacturing plant was established to build Doosan’s own cylinder blocks and cylinder heads. A cylinder block and a cylinder head are 5C parts of engines which are the most important parts of an engine. Let’s look into how a cylinder block and a head are built. First, main material, metal should be melted. Melted metal is poured into a mold to harden into shape. We called this “Liquid Metal“ and pour them into a mold which is made from sands. In order to produce a block and a head which have complicated internal and external surface, “Core” procedure is necessary. A core is a replica, of the internal features of the part to be cast which mold internal of parts. Over 1,500 degrees Celsius of liquid metal is pored into a mold and wait for a while to cool down a temperature. Then next, inside and outside of parts are cleaned. Now parts are ready to be painted. Final process is inspection. After going through thorough test, then it’s good to be delivered to customers. Doosan Infracore has 18 models of cylinder blocks and 10 models of cylinder heads Does Doosan Infracore only build its own parts? Of course not. We also develop new products. Here is a customer who needs a new hydraulic pump and other parts. New equipment require newly designed parts. Doosan Infracore develops new parts with a customer. Long and rich experiences in development of various products and mass production are enable to meet diverse demands of customers. Doosan Infracore always tries to meet the needs of customers.
