Manual Extract – Relief Valve

If the rail pressure relief valve is not opened quickly enough, it is pushed open, i.e. opening is forced. To push open the rail pressure relief valve, the Y091 dispensing unit is opened by interrupting the power supply and the fuel supply is blocked via the injections. The rail pressure increases strongly until the opening pressure of the rail pressure relief valve is reached. If pushing is not successful, the engine is switched off, for example by a mechanically jamming rail pressure relief valve.
