Function
As a result of a lower number of clock pulses of the injection timing solenoid valve (Y60) (pressure rise) an earlier start of injection is achieved by overcoming the force of the spring (11/10a).
Earlier start of injection, engine at full load
11/10 Adjusting plunger
11/10a Spring
11/10b Restrictor 0.6 mm
B Pump internal pressure (approx. 8 bar)
R Pressure in fuel pump return flow
