    Mechanical control valves

    Overview

    The tractor may be equipped with one type of mechanical control valves: premium (450 Series).

    Premium-couplers control valves also have an additional lock function (position 3), which holds the control lever in the raise or lower position until the pressure in the oil circuit has reached a predetermined value (e.g., when the control cylinder has reached its end position).

     

    In position 2, the control lever returns to neutral as soon as it is released and is the setting for normal hydraulic operation.

     

    If an implement is connected, pressure connection has to be connected to the lower coupler. With standard SCVs, a valve prevents sudden loss of pressure caused by leakage when the engine is shut off.

     

    On premium SCVs, the likelihood of leakage is further diminished.

    SCV flow setup

    Overview

    SCV flow rate can be programmed between 0.04 and 10 allowing fine tuning for implements with different hydraulic requirement.

    Behavior can be set between linear (red), progressive (green), or a combination (yellow) for exact flow modulation and precise valve management.

    • Linear means that the distance travelled by the SCV/ICV corresponds to the distance travelled by the control lever/multifunction lever
    • Progressive means that initially the distance travelled by the SCV/ICV is less than that travelled by the control lever/multifunction lever (giving a more sensitive start to the movement)

    Series turbochargers

    Overview

    The PowerTech PSS 4.5L and 6.8L utilizes two turbochargers – a VGT and a fixed geometry turbocharger, providing the torque rise and engine response needed to meet varying load conditions.

    Fresh air is first drawn into the low-pressure fixed geometry turbocharger and compressed to a higher pressure. The compressed, higher pressure air is then drawn into the high-pressure VGT, where the air is further compressed. By splitting the work between two turbochargers, both can operate at peak efficiency and at slower rotating speeds.

    Benefits

    • Deliver high power density
    • More low-speed torque and responsiveness to meet varying load conditions

    VGT

    Overview

    The VGT is electronically controlled and actuates the turbo vanes as required to maintain peak engine performance.

    The turbocharger’s vanes are in the exhaust flow. The opening or closing of the vanes changes the outlet volume and airflow speed against the turbocharger turbine. When exhaust flow is low, the vanes are partially closed. This partial closure increases the pressure against the turbine blades to make the turbocharger spin faster and generate more boost pressure.

    The ability to keep the airflow at optimum levels provides more consistent engine boost pressure and the ability to respond to load quickly across the entire engine rpm range. This system is without the turbo lag that can be found on some engines.

    Benefits

    • Increased low rpm torque 
    • Quicker response to load
    • Increased peak torque
    • Improved fluid economy
    • Improved performance at high altitudes

    Air-to-air after cooling

    Overview

    Air-to-air after cooling lowers the intake manifold air temperature and provides more efficient cooling while reducing cylinder firing pressure and temperatures for greater engine reliability. Since lower temperature air is denser, a higher volume of air flows into cylinders so the engine can meet the increasing horsepower demands. Lowering the intake manifold and cylinder temperatures also aid in lowering the combustion temperature, which lowers the NOx produced as a result.

    Benefits

    • Higher horsepower
    • Less NOx production

    HPCR fuel injection system

    Overview

    Every PowerTech PSS 4.5L and 6.8L engine utilizes a HPCR fuel system to efficiently supply fuel to injectors. The high-pressure fuel pump instantly responds to requirements for more or less fuel flow or pressure. This electronically controlled, high-pressure pump delivers pressure on demand according to the application requirements. Pressure on demand ensures an efficient injection system resulting in high-injection pressure independent of engine speed.

    Engine control unit (ECU)

    Overview

    The ECU uses signal inputs from sensors and pre-programmed performance modeling to control critical engine functions such as fuel quantity, injection timing, air-to-fuel ratio, multiple fuel injections, amount of cooled exhaust gas recirculation (EGR), and a host of other control parameters.

    Benefits

    • Optimized fluid economy
    • Maximum engine performance

    Details

    Each injector is controlled individually by the ECU. The ECU turns the injector on and off during each firing cycle to control the fuel delivery into each cylinder.

    Load and speed sensing allow each cylinder’s fuel delivery rate to be adjusted independently at the individual injector. With each injection cycle, the ECU can make the following adjustments on the go:

    • Number of injections
    • Fuel pressure in the common rail
    • Start of injection
    • Duration of injection

    This management system is connected to the transmission, allowing the engine and transmission to respond simultaneously.

    Cold weather and high-altitude compensation are also precisely controlled for quality starts regardless of weather and maximum performance at high elevations. The ECU also features improved diagnostic capabilities. It is faster, has more working memory, and is responsible for monitoring and executing all aspects of the Integrated Emission Control System.
