The increasing demands placed upon the diesel fuel-injection system made it necessary to continually develop and improve the fuel-injection pump. Following systems comply with the present state-of-the-art:

– In-line fuel-injection pump (PE) with mechanical (flyweight) governor or Electronic Diesel Control (EDC) and, if required, attached timing device,
– Control-sleeve in-line fuel-injection pump (PE), with Electronic Diesel Control (EDC) and infinitely variable start of delivery (without attached timing device),
– Single-plunger fuel-injection pump (PF),
– Distributor fuel-injection pump (VE) with mechanical (flyweight) governor or Electronic Diesel Control (EDC). With integral timing device,
– Radial-piston distributor injection pump (VR),
– Common Rail accumulator injection system (CRS),
– Unit-injector system (UIS),
– Unit-pump system (UPS).
