Operation fuel delivery air induction for 1988 Mercedes Benz 260E (124 Chassis) L6-2599cc 2.6L SOHC (103)
A mechanical hydraulic injection system provides the basis for the Bosch KE-Jetronic
(CIS-E) fuel system. The mechanical portion of the CIS-E system consists of the mixture
control unit (air flow meter and fuel distributor), primary pressure regulator, fuel accumulator, cold
start valve, fuel injectors, pumps, filter, lines, tank and fuel cooler. In addition, electrical
controls have been added for increased flexibility to meet todays more stringent
performance and exhaust emission requirements. Refer to "COMPUTERIZED ENGINE
CONTROLS" for a detailed description of electronic components.

The electro-hydraulic actuator is bolted to the side of the fuel distributor. It consists of a
plate valve fastened between two electromagnets.
By varying the electric current to the electro-hydraulic actuator and changing the
strength of the magnets, the plate valve can be moved. The varying position of the plate
valve controls the quantity of fuel allowed into the lower chamber of the fuel distributor,
causing the differential pressure to vary. The operating range is from -50 to +150mA.
Differential pressure will be from 0 bar to about 1.6 bar (24 PSI) less than system
pressure.
