Excavator Engine Assy DX420 DX520 DX480LC Complete Engine DV11



Brief Introduction:
DOOSAN 's DV11 diesel engine apply the over head valve and the turbocharger,is the electric control engine of the air cooling type by the cooling fan.The fuel is stored under pressure in the high-pressure accumulator (the "CommonRail") ready for injection. The injected fuel quantity is defined by the driver, andthe start of injection and injection pressure are calculated by the ECU on the basis of the stored map. The ECU then triggers the solenoid valve sensor that theinjector (injection unit) at each engine cylinder injects accordingly. Oil gallery cooling is used for thepiston of the engine. The design of the gallery, the design and location of the oil spray nozzle and the quantity of oil flowing in the gallery are critical in order to achieve the desired temperature reduction. The cross section shape of the gallery should be designed to achieve sufficient oil movement maximize cooling efficiency.


Engine Model

Thermostat Type Wax pallet type (79-94 ℃)
Water Temperature Indicator Water temperature sensor mounted
Air compressor type Water cooled
Air compressor capacity 550 (275 × 2 each)
Air compressor revolution ratio 1 : 1.265 (Engine speed : Air compressor speed)
Turbo charger

Engine stop system Fuel feeding shut-off by ECU
Common Rail System
Pressure generation and fuel injection are completely decoupled from each other in the "Common Rail" fuel injection system. The injection pressure is generated independent of engine speed and injected fuel quantity stored in the ECU.
Lubrication System
The engine is equipped with force-feed lubrication. The pressure is produced by agear pump whose drive gear is in direct mesh with the crankshaft gear at the flywheel end. The oil pump draws the oil from the oil sump and delivers it through the oil cooler and oil filter to the main distributor gallery and from there to the main bearings, big-end bearings and camshaft bearings as well as to the small-end bearings and the rocker arms. The turbocharger is also connected to the engine lubricating system. The cylinder walls and timing gears are splash-lubricated. Each cylinder has an oil jet provided for cooling the underside of the pistons. Thelube oil is cleaned in a full-flow oil filter.
