Timing valve
The timing valve in the common rail system is operated by a cam and
lever (Figure 2.15). When the timing valve is lifted by the cam and lever
the high-pressure fuel flows to the injector. The timing valve operating
lever is fixed to a sliding rod which is positioned according to the
manoeuvring lever setting to provide the correct fuel quantity to the
cylinder.
