Diesel distributor fuel-injection pumps VE - K-Jet.org

TypesThe increasing demands placed uponthe diesel fuel-injection system made itnecessary to continually develop andimprove the fuel-injection pump.Following systems comply with thepresent state-of-the-art:– In-line fuel-injection pump (PE) withmechanical (flyweight) governor orElectronic Diesel Control (EDC) and, ifrequired, attached timing device,– Control-sleeve in-line fuel-injectionpump (PE), with Electronic DieselControl (EDC) and infinitely variablestart of delivery (without attachedtiming device),– Single-plunger fuel-injection pump (PF),– Distributor fuel-injection pump (VE)with mechanical (flyweight) governoror Electronic Diesel Control (EDC).With integral timing device,– Radial-piston distributor injectionpump (VR),– Common Rail accumulator injectionsystem (CRS),– Unit-injector system (UIS),– Unit-pump system (UPS).Fuel-injectiontechniquesFields of applicationSmall high-speed diesel enginesdemand a lightweight and compact fuelinjectioninstallation. The VE distributorfuel-injection pump (Fig. 2) fulfills thesestipulations by combining– Fuel-supply pump,– High-pressure pump,– Governor, and– Timing device,in a small, compact unit. The dieselengine’s rated speed, its power output,and its configuration determine theparameters for the particular distributorpump.Distributor pumps are used in passengercars, commercial vehicles, agriculturaltractors and stationary engines.Fig. 2: VE distributor pump fitted to a 4-cylinderdiesel engineFuel-injectiontechniquesUMK0318Y9
