Motor Doosan DV11

Basic parameters
Engine type: water-cooled, 6-cylinder V-type 90°, turbocharged, air intercooled.
Combustion chamber type: direct injection.
Number of cylinders - bore × stroke: 6-128×142mm.
Total displacement: 10,964cc.
Compression ratio: 17.1:1.
Engine size: length × width × height is 1,206x1,031x1,070mm.
Engine weight: 904kg.
Direction of rotation: counterclockwise from the flywheel end.
Ignition order: 1-4-2-5-3-6.
Performance parameters
Output power: maximum up to 309kW (420PS)/1,800rpm.
Torque: maximum torque is 1,834N・m (187kg・m)/1,200rpm.
Fuel consumption: The minimum fuel consumption is 203g/kW・h (149g/PS・h).
Structural features
Cylinder block: Made of single-piece alloy cast iron, with rigidity treatment below the centerline of the crankshaft, and replaceable wet cylinder liners and independent cylinder heads.
Piston, connecting rod and crankshaft assembly: The crankshaft is forged in one piece and has undergone dynamic balancing tests. The connecting rod is die-forged and has an oblique cut. It can be removed from the top of the cylinder block together with the piston. The crankshaft and connecting rod use steel-backed lead-copper alloy bearings.
Valve mechanism: Overhead valves are used, and their movement is achieved by the camshaft driving the carburized tappets, push rods and rocker arms.
Fuel system
Fuel high-pressure pump type: Bosch CP3.4 fuel high-pressure pump.
Nozzle type: Multi-hole (8xφ0.197 Bosch DLLA146).
Fuel injection pressure: Working pressure 1,600bar.
Control type: Electrical control type (ECU), common rail system, fuel is under pressure in the high pressure accumulator ("common rail") ready for injection, the amount of fuel injected is determined by the driver, the start of injection and injection pressure are calculated by the ECU based on the data.
Lubrication and cooling system
Lubrication method: forced lubrication, the oil pump is a gear pump driven by the crankshaft, and the oil cooling form is cold water type.
Cooling method: pressurized circulation, the cooling water pump is a belt-driven centrifugal type, the cooling water volume (in the engine) is 14.3 liters, the thermostat is a wax plate type, and the opening temperature is 95°C.
Other features
Turbocharger: exhaust drive type (wastegate).
Starter motor: voltage - output is 24V-6.0kW.
Oil filter type: full flow (filter element).
