  • Fuel line

    In conventional diesel engines injection pressure is generated for each injector individually. A direct injection engine based on the common rail principle separates the two functions pressure generation and injection by first storing the fuel under high pressure in a central container ("common rail") and delivering it to the individual injection valves (injectors) only on demand. This way an injection pressure of up to 1,600 bar (23,200 psi) is available at all times, even at low engine speeds. The high pressure produces a very fine atomisation of the fuel leading to better and cleaner combustion. Moreover, the fuel supply is not dependent on the engine revolutions but can be optimised independently. The time and duration of injection is not fixed (as in older conventional engines) but can be chosen independently for every operation point in order to optimise combustion and emissions.

    Benefits of the common rail principle compared to conventional engines are lower engine noise levels, stronger performance and greater combustion efficiency leading to lower emissions and enhanced fuel economy.

  • Injector

    The main injector components are: Hole-type nozzle(c), hydraulic servo-system(b), solenoid valve(a). The forces required to open and close the nozzle needle cannot be generated by the solenoid valve on its own. The nozzle needle is therefore indirectly triggered via a hydraulic force-amplification system.

    1. Injector closed With the solenoid valve closed, the complete chamber volume and the rail are at the same pressure. The nozzle needle is forced against its seat by a spring. 2-1. Solenoid ON When the solenoid valve opens, fuel flows from the valve control cavity and into the fuel return.The feed throttle prevents complete pressure equalization, and the pressure in the cavity drops.

    2-2. Start of injectionHydraulic servo spool move up side and the excess pressure in the chamber volume overcomes the spring force and lifts the needle so that injection can start.

  • Rail

    1. High pressure storage of injection system2. Rail contains pressure relieve valve(a) and rail pressure sensor(b).3. Pressure relief valve- Pressure relieve valve is a mechaninical safety device, which opens at 1950 (-100) bar / 28,275 psi (-1,450 psi) and protects the system concerning over pressure caused by any malfunction.-If opened the rail pressure remains in the range of 650 - 850 bar (9,425~12,325 psi) (dependend on speed and load). The engine keeps running but if necessary with decreased performance (limp home mode)-Under usual conditions the relief valve will not open during engine operation.4. Rail pressure sensor- Output signal goes to ECU and ECU controls FCU by using this signal.- If any malfunction is detected, the ECU may force the pressure relief valve to open by putting over pressure onto the system.

    Picture text:

  • Fuel control unit (FCU)FCU controlles filling of high pressure pumps. It is just delivered as much as needed to reach or keep the rail pressure set-point.This is an inverse proportional PWM valve. At the inside of valve, there are overflow valve and bleed-off orifice.

    Picture text:

  • IEGR(Jacobs system)NOx reduction solution is provided by Internal Exhaust Gas Recirculation (IEGR) which is altering engine valve lift. Jacobs IEGR reduces peak combustion temperatures and, therefore, reduces the formation of Nitrogen Oxides (NOx) to levels acceptable to meet upcoming emissions standards.

    Picture text: A: IEGR SolenoidB: Control valveC: Slave pistonD: Master pistonE: Connection passageF: Bleed hole(1 mm, 0.04 in)

  • IEGR operation1. IEGR consists of a solenoid valve, control valve, and master and slave pistons. These components are assembled into a housing. 2.When the solenoid is de-energized, the control valves move down and the high-pressure oil is released through the tops of the control valve bores.3. When the IEGR is activated, the solenoid allows oil to pass to the control valve. The control valve moves up and the check ball in the control valve is unseated, allowing oil to fill the master/slave piston circuit.4.The oil pushes the master piston out, and when rocker motion pushes the master piston back, high pressure is created which seats the check ball in the control valve.5.Continued rocker motion causes the high-pressure oil to move the slave piston. The slave piston motion causes the exhaust valves to open. As the rocker moves back down, the master piston follows, and the slave piston moves up, allowing the valves to close again, ready for the next cycle. These cycles continue as long as the brake solenoid is energized.

  • Engine speed and work mode control

    **Comparing B-Series, Engine rpm and pump input power of H and G mode are increased(Working mode refining).

    In control system, we can have 10-step engine speed and 5 work-modes.By rotating engine speed control switch, Engine rpm and work-mode is set at the same time. You can see the specification at the next page.

    This function allows the operator to select the engine speed and work mode according to working condition and to optimise the machine performance and fuel efficiency.

    Principle is simple. Excavator converts the mechanical power from engine to hydraulic power using hydraulic pump. So engine power should be bigger than pump consuming power. If not, engine could be stall or stop.

    The V-ECU always receives the current engine speed from the E-ECU . It balances engine horsepower and pump consuming power by changing output current to power-shift valve.(ESSPC: Engine Speed Sensing Pump Control)

    Power-shift valve is kind of proportional valve using PWM signal. By controlling power-shift valve, we can change the swash plate angle and finally change pump flow rate. So system can keep pump torque maintain lower than engine torque at the selected engine speed.

    (1) In I (Idle)& F (Fine) mode, current is fixed at specified value regardless of engine load condition. That means engine output is bigger enough compared to pump input power.

    In P (Power max.), H (Heavy duty), G (General) mode,

    (2) If engine is not loaded, it uses the specified current value at each engine speed.(3) When engine is loaded, VECU increase the current of power-shift valve to decrease the consuming power of pump.

  • Engine speed and work mode control(Without P)

    **Comparing B-Series, Engine rpm and pump input power of G mode are increased(Working mode refining).

    Picture text:

  • Automatic Return to Idle

    When operator turns on the function auto-idle & does not use any joystick & pedal, engine speed automatically goes down to I1 mode. This increase fuel economy and decrease noise. After engine has decelerated, if the operator changes one of input signals, then engine speed return to the previous speed.

    Default time delay is 5 second. This can be adjusted form 3 to 10 seconds by VCADS Pro.

  • Safe start & Stop

    1. Safe start- Key off --> ON- Engine is stop condition(rpm=0)- VECU request I2 to EECU & energize battery relay(RE3101)**Whenever start the engine, default mode will be I2 regardless of initial position of rpm control switch to prevent sudden engine rpm surge.

  • Rebound damping valve operation

    (1) Neutral position

    (2) Start of swing

    (3) full swing

    (4) Joystick return to the neutral. PA pressure goes high.

    (5) PA will reach to relief valve set pressure and machine will stop.In this point, PA=Relief set pressure and PB=Tank pressure.There is pressure difference between PA & PB. That means rebound of machine.

    (6) When machine starts rebound, PA pressure drops down.If PA is lower than the spring force of damping valve, those two valves starts to return to original position. But return speed is different because of small hole of front valve. This speed difference make gap between two valves. This gap connects A & B ports. As result, PA & PB will be same for short time. That means there is no force to rotate motor again.Finally, this valve can stop the machine at the early stage of first rebounding.During normal slewing, the port A & B must be disconnected at any case.

  • Parking brake operation

    The slew brake is spring applied and hydraulically released. Friction plates are splined to cylinder block and rotate with cylinder block. Mating plates are splined to motor casing.

    1. When there is no SH signal, parking brake will be engaged by spring force.

    2. When there is SH signal, primary pilot pressure(40 bar / 580 psi) goes to brake piston through PG and push the brake piston against spring.

    3. When there is no SH signal, Pilot pressure can not go to the brake chamber and oil in side of that chamber shoud be drained. But there is only small hole for drain near to time delay valve. In the beginning, oil pass through the orifice and go to tank, but pressure will be built up in front of the orifice and push the valve. Now the valve blocks tank line. There is no flow to tank. That means there is no pressure difference between front and rear side of valve. But the valve has return-spring at the rear side. So the valve can return to initial position and open tank passage again. The oil from brake chamber can go to tank again.

    Open-close-open movement can delay the parking brake engaging time for 5 seconds.

  • Brake valve operation

    1. Brake valve is now at neutral position.

    2. The pressure of supply line goes high and this pressure applies to the backside of brake valve and then pushes the brake valve against spring. So return side oil can go to tank.

    3. When machine travels at the down slope, this can cause overrun. That means the amount oil of supply line is less than expected. In this case we need brake function to control the machine from over-speed.

    The pressure of supply line becomes low and the brake valve return to the neutral position. So we can block the return line and slow down the machine speed. During this period, the relief valve help machine to be driven smoothly.(Low and high pressure relief)

  • Speed changeover

    1. When the pilot pressure at port P is disconnected, the spool moves upward by the spring force & hydraulic force which is applied to the differential area between red section and yellow section. The oil in chamber of swash piston flows to the drain line, and the swash plate moves to increase swash angle, so the motor rotates at low speed.

    2. When the pilot pressure at port P is connected, spool moves downward by the pressure at Pi. The supply oil through check ball folws to the swash piston. Swash pisto pushs the swash plate and decrease swash angle, so the motor rotates at high speed.

    3. In this picture, the force by P port pressure acts against the force by supply pressure which is applied on the differential area and spring. When the supply pressure reach to specified value, the force by supply pressure and spring overcomes the force by Pi pressure. So the spool moves upward. The oil in chamber of swash piston flows to the drain line, and the swash plate moves to increase swash angle, so the motor rotates at low speed and high torque.

  • Reducing valve operation

    In order to release parking brake, system uses the pressure from main pressure of supply line. So we need to decrease the pressure by using this valve.

    (1) Supply pressure goes to brake chamber to release the brake.

    (2) If the pressure of brake chamber exceed the specified value(spring tension), main pressure push the valve to the right becasue of area difference of valve and disconnect passage between main pressure and brake chamber. Therefore the parking pressure cannot exceed the setting pressure.

    This pump assembly consists of two pumps connected by spline coupling.The suction and delivery ports are integrated at the connecting section of the two pumps: The common suction port serves both the front and rear pumps.The pump consists of rotary group, swash plate group and valve block group.

    The rotary group consists of front drive shaft, cylinder block, piston and shoe, set plate, spherical bushing, and cylinder spring. The drive shaft is supported by bearings. The shoe is caulked to the piston to form a spherical coupling. It has a pocket to relieve thrust force generated by loading pressures and create a hydraulic balance so that it slides lightly over shoe plate. The sub group composed of a piston and a shoe is pressed against the shoe plate by the action of the cylinder spring through the set plate and spherical bushing. Similarly, the cylinder block is pressed against valve plate by the action of the cylinder spring.

    The swash plate group consists of swash plate, shoe plate, swash plate support, tilting bushing, tilting pin and servo piston.The servo piston moves to the right and the left as hydraulic oil controlled by the regulator flows to a hydraulic chamber located on both sides of the servo piston. The force exerted on the tilting pin by the servo piston causes the swash plate to slide on support to change the tilting angle.

    The valve block group consists of valve block, valve plate and valve plate pin. The valve plate which has two crescent ports is attached to the valve block to feed oil to and collect oil from the cylinder block. The oil discharged via the valve plate is routed to an external pipe line by way of the valve block.

  • Sectional view

    This pump assembly consists of two pumps connected by spline coupling.The suction and delivery ports are integrated at the connecting section of the two pumps: The common suction port serves both the front and rear pumps.The pump consists of rotary group, swash plate group and valve block group.

    The rotary group consists of front drive shaft, cylinder block, piston and shoe, set plate, spherical bushing, and cylinder spring. The drive shaft is supported by bearings. The shoe is caulked to the piston to form a spherical coupling. It has a pocket to relieve thrust force generated by loading pressures and create a hydraulic balance so that it slides lightly over shoe plate. The sub group composed of a piston and a shoe is pressed against the shoe plate by the action of the cylinder spring through the set plate and spherical bushing. Similarly, the cylinder block is pressed against valve plate by the action of the cylinder spring.

    The swash plate group consists of swash plate, shoe plate, swash plate support, tilting bushing, tilting pin and servo piston.The servo piston moves to the right and the left as hydraulic oil controlled by the regulator flows to a hydraulic chamber located on both sides of the servo piston. The force exerted on the tilting pin by the servo piston causes the swash plate to slide on support to change the tilting angle.

    The valve block group consists of valve block, valve plate and valve plate pin. The valve plate which has two crescent ports is attached to the valve block to feed oil to and collect oil from the cylinder block. The oil discharged via the valve plate is routed to an external pipe line by way of the valve block.

    The 2-way hydraulic circuit is almost same with EC210B Prime which has X1 2-switch control and 2 pump flow option. The machine will be usually used for log loader and road construction machine. Bucket is used and harvester operation is available in Hammer selection.

    If additional ECU for forestry attachemnt is installed, hammer & Shear can be controlled by PWM valve(PWM-A1, PWM-A2)

    During travel operation, the X1 Conflux is deactivated by the travel pilot pressure switch operation.
