Stricter legislation on clean air together with unstable fuel prices tending upward are increasing the demand for clean, economical automobiles. So the development of our Efficiency Line Generators (EL) concentrated not only on high performance but above all on increased efficiency. The result: a new, extremely efficient generation of generators with a particularly high degree of efficiency permitting reductions in fuel consumption as well as CO₂ output of up to 2% – good for motorists, good for the environment and an important sales argument for vehicle manufacturers.

The greater the efficiency, the more effective the generator and the less fuel required for generating electrical energy. Thanks to their further improved electrical layout, the new generation of generators achieves an very high degree of efficiency which can – if an optional High Efficiency Diode (HED) from Bosch is used – amount to as much as 77% (according to VDA). The HED increases not only the efficiency but also the performance of the generator.

By comparison with their predecessors, the performance of these generators has been further increased, especially at low engine speeds. Our EL series is available in different sizes. These cover a performance range from 130 to 210 Ampere (at 6,000 rpm). EL generators are thus suitable for reliably supplying the widest possible range of vehicle electrical systems with energy.

EL generators are quiet in operation and can be supplied with multi-function regulators (MFR) or regulators with a communication interface such as LIN, for instance. Yet another convincing feature is their light, compact design and their heat resistance to temperatures of up to 125 °C. Different mounting situations within the engine compartment are thus no problem.
