THE PUMP-LINE-NOZZLE SYSTEM (1927- BOSCH)

Rugged butcomplicated mechanical devices –Upto 115MPa injection Pressure. Injection timing are pre-determined (designed in - to the pumping element geometry)

MECHANICAL UNIT INJECTOR

Features: Mechanically Actuated Rack / Gov. Controlled Fixed Timing Higher Volumetric Efficiency Higher Injection Pressures

Drawback •Many rods and levers inthe linkage system to synchronize and control each injector. •System governed by complex governor
