Starter Motors and Generators Modular concept for Heavy Duty generators – fuel-saving solutions Introduction More performance with greater fuel economy and fewer emissions? The modular generator concept from Bosch makes this possible. With the various features, Efficiency E Power P Digital Interface D the Heavy Duty (HD) generators can meet any power requirement while opening up new savings potentials which will benefit drivers, haulers and the environment. Longlife L Temperature T Belt Tension B Hot Environment H Customer benefits ▶ Feature concept focuses on customer benefit ▶A djustment for reduced fuel consumption and emission ▶A pplication-specific solutions Digital Interface PWM (pulse width modulation) Interface: for optimized battery charging Our established product range of multifunction regulators has been expanded by a version with a digital PWM interface. This permits voltage regulation direct via the engine control unit. LIN (local interconnect network) Interface: the smart solution What is more, Bosch offers for the HD generators a regulator with bidirectional LIN interface. This makes Customer benefits it possible not only to use the engine control unit to ▶ Longer battery life due to controllable adjust various regulator parameters but also to send charge voltage ▶ Optimum adjustment of charging voltage to ambient temperature ▶ Helps to reduce fuel consumption and CO2 output by adapting the charge voltage ▶ Combinable with all HD generators back reports on different generator status parameters. For example the generator can be switched off completely during acceleration. In the boost mode its performance potential is fully exhausted again. In addition, the 28 V version incorporates the ability to synchronize various generators within one electrical system. Starter Motors and Generators | Modular concept for Heavy Duty generators – fuel-saving solutions Efficiency: improved efficiency Due to improvements in the stator geometry and the magnetic circuit HD-E (Efficiency) generators are characterized by high power output (up to 3.4 kW at 28 V) with average efficiency of up to 75 % and a maximum of Field of application for HD-E generator 14 V 28 V IG at 6,000 rpm (A) 80 %, as well as a power density of 1.05 W/cm3.
