Major items that determine the life of the engine as the basic structure of the engine. Manufactured and supplied directly by Doosan Infracore's unique technologies. The reputation of Doosan Infracore’s diesel engines, ranging from industrial engines to car engines, begins with the cylinder block.
The core precision part of the engine that should have enough strength and rigidity, as it rotates at high speed under heavy load, and balance should be maintained. Quality and price have already been proven by being adopted as OEM (Original Equipment Manufacturing) parts for Doosan Infracore's diesel engines and world's leading engine makers.
A core engine part that transfers the reciprocating motion of the piston to the crankshaft; its quality and price have been proven by being adopted as an OEM part for Doosan Infracore’s diesel engines and leading engine companies around the world.
A highly technology-intensive part that makes a reciprocating motion while maintaining airtightness inside the engine. Doosan Infracore's genuine piston is an eco-friendly part that suppresses the pollutant emission of the engine, and piston other than the standard type is supplied in stages depending on the maintenance situation.
The precision consumable part of the engine that requires maintenance on a regular basis. A part that demands airtightness inside the engine and protects the cylinder, requiring proper replacement depending on the wearing condition. A part other than the standard type is supplied in stages depending on the maintenance situation.
A high-precision consumable part assembled to the piston and divided into functions such as airtightness, oil removal, and heat conduction. It should be replaced properly according to the engine condition, in order to extend the service life of the engine and reduce environmental pollution by suppressing the emission gas.
A genuine filter that applies strict quality control from the selection of filter paper does not allow even fine impurities as it is designed to fit the various functional areas of the equipment. Choose a genuine filter to extend the equipment life and maximize equipment efficiency.
A part that keeps the engine at proper temperatures by cooling the engine during operation.
Plays the role of maintaining airtightness and preventing coolant and engine oil leak by pressing each side of the engine. Differently sized gaskets are provided depending on each unit product and maintenance condition.
A high-precision part that adjusts the intake and exhaust stroke of the engine seamlessly and determines engine power.
Main Bearings & Thrust Bearings
An important consumable part, the metal bearing itself should withstand varying loads without damage and should not wear out excessively. Standard type and large size are supplied depending on the maintenance situation.
A place where engine cooling oil exchanges heat using coolant, which enables the engine to maintain constant temperature continuously.
A part that acts like an air pump that applies pressure to air intake to improve engine power, turning force, and fuel consumption rate.
Fuel Injection Pumps
One of the key engine parts that compresses fuel at high pressure and supplies fuel to the nozzle at a certain timing.
As the engine cannot start itself, the starter starts the engine by turning the crank from the outside. It should be selected according to the engine capacity. The starter is supplied for all models of the company equipment.
Equipment for generating and supplying electricity to the engine, should be selected according to the performance and capacity of the equipment.
A key vehicle part that compresses air. Managed by self-design and strict quality control. Assembled finished products and repair tools are supplied.
Equipment that generates hydraulic pressure used for the power handle of the vehicle. Directly connected to the engine, this equipment generates and supplies hydraulic pressure continuously as required by the vehicle.
Fly Wheels & Housings
A part that stores motive power generated by the engine and transfers it to the outside. The flywheel is a rotating body, and the housing protects it and holds the engine equipment at the same time.
