The cylinder block, the basic structure for an engine, is a key component that determines the durability of an engine. Doosan’s cylinder blocks have been manufactured and supplied based on Doosan Infracore’s own technical expertise accumulated for years. Cylinder blocks act as the basic framework for Doosan Infracore’s off-highway and on-highway diesel engines.

The crank shaft, a key engine component, needs to be strong and hard enough to withstand high spin speeds and a heavy load while maintaining its balance. Our crank shafts, which have been used for Doosan Infracore diesel engines and chosen as Original Equipment Manufacturing(OEM) parts by top-tier engine makers across the world, have already been highly recognized in global markets for their high quality and price competitiveness.
The connecting rod, one of the key engine components, delivers the back and forth motion of a piston to a crank shaft. Our connecting rods, which have been used for Doosan Infracore diesel engines and chosen as OEM parts by top tier engine makers across the world, have already been highly recognized in global markets for their high quality and price competitiveness.
The piston, a high-precision and technology-intensive component, moves back and forth, keeping the inside of an engine sealed. Doosan Infracore’s genuine pistons are eco-friendly parts that can prevent engines from emitting pollutants. Diverse types of pistons including standard ones are supplied by phase, depending on the status of maintenance.
Liners are high-precision engine parts that require regular maintenance. These parts keep the inside of engines fully sealed and protect cylinder blocks. Moreover, they should be properly replaced, depending on the degree of use. Diverse types of liners including standard ones are supplied by phase, relying on the status of maintenance.
Ring kits, high-precision entire parts, are fitted to pistons to keep engines sealed, remove oil and conduct heat. Depending on the status of engines, they should be properly replaced to extend durability of engines, control emissions, and thereby reduce environmental pollution.
Doosan genuine filters are subject to strict quality control including the selection of filter paper. The filters are designed to flawlessly fit each functional part and sift out impurities. Doosan genuine filters extend the life of engine and maximize equipment effectiveness.
Water pumps properly control engine temperatures by cooling engines in operation.
Gaskets keep engines perfectly sealed and prevent cooling water and engine oil from leaking. Relying on the status of each unit and maintenance, different sizes of gaskets are supplied.
Cam shafts, core high-precision parts, flawlessly control engine intake and exhaust systems and play a key role in determining engine power.
Main Bearings & Thrust Bearings
Metal bearings themselves should withstand changing loads without being damaged and must not be excessively worn out. Standard or large bearings are supplied, depending upon the status of maintenance.
Via oil coolers, engine cooling oil exchanges heat with cooling water. The coolers enable engines to maintain consistent temperatures.
The turbo charger acts as a kind of air pump that puts pressure on intake to improve engine power, torque and fuel consumption.
Fuel Injection Pumps
The fuel injection pump, one of the key engine parts, compresses fuel at a high pressure and supplies it to the nozzle at a right time.
Engines can not be self-activated. Therefore, to put engines into operation, starters turn crank shafts by force from outside. They should be properly selected, considering engine capacity, and are supplied for all our vehicles.
Generators produce and supply power to engines in operation. They should be properly chosen, taking into account engine performance and capacity.
Air compressors, key vehicle parts, are managed via in-house designing and thorough quality control. Assembled compressors and maintenance tools are supplied.
Steering pumps create oil pressure for power handles. Directly linking to engines, they ceaselessly generate and supply oil pressure to vehicles.
Fly Wheels & Housings
Fly wheels & housings store and deliver power generated by engines to the outside. Fly wheels are rotating objects while housings protect the wheels, on which engine equipment is also installed.
