  • Electronics is coming more and more to the forefront in the control and management

    of the diesel engine, whereby the question is often raised Is it really necessary to fill

    the vehicle with so much electronics ?

    The point is though, without electronics it would be impossible to detect a large

    number of important variables, such as engine speed, quickly enough for them to be

    used for engine management. Electronic control is behind the modern diesel engine

    having become more powerful, more efficient, quieter, cleaner, and more economical.

    These facts hold true irrespective of the engines operating range or mode.

    Electronic Diesel Control, EDC, permits the implementation of such auxiliary func-

    tions as smooth-running control (SRC).

    EDC is applied for all modern diesel injection systems:

    In-line injection pumps, PE, Distributor injection pumps, VE, VR, Unit Injector System, UIS, Unit Pump System, UPS, Common Rail System, CRS.

    Although these injection systems differ in many respects, and are installed in a wide

    variety of different vehicles, they are all equipped with a similar form of EDC.

    This Technical Instruction manual describes the Electronic Diesel Control and all

    its components. The differences between the individual injection systems are shown in

    tabular form (Pages 12 through 17). The manual thus provides the reader with a com-

    prehensive overview of the various diesel fuel-injection systems from the point of view

    of their open and closed-loop electronic control.

  • Diesel engines are characterized by theirhigh levels of economic efficiency. Since thefirst series-production injection pumpswere introduced by Bosch in 1927, injec-tion-system developments have continuedunceasingly.

    Diesel engines are employed in a wide rangeof different versions (Figure 1 and Table 1),for example as:

    The drive for mobile electric generators (up to approx. 10 kW/cylinder),

    High-speed engines for passenger carsand light commercial vehicles (up to approx. 50 kW/cylinder),

    Engines for construction, agricultural,and forestry machinery (up to approx. 50 kW/cylinder),

    Engines for heavy trucks, buses, and trac-tors (up to approx. 80 kW/cylinder),

    Stationary engines, for instance as used inemergency generating sets (up to approx. 160 kW/cylinder),

    Engines for locomotives and ships (up to 1,000 kW/cylinder).

    Technical requirements In line with the severe regulations coming intoforce to govern exhaust and noise emissions,and the demand for lower fuel consumption,increasingly stringent demands are beingmade on the diesel engine's injection system.

    Basically speaking, depending on the partic-ular diesel combustion pr
