Embodiment Construction
[0026] figure 1 A system diagram showing an electronically controlled internal combustion engine 1 with a common rail system. The common rail system comprises the following mechanical components: a low-pressure pump 3 for supplying fuel from a fuel tank 2; a variable suction throttle 4 for influencing the flowing fuel volume flow; for supplying under increased pressure A high pressure pump 5 for fuel; a pressure accumulator 6 for accumulating fuel; and an injector 7 for injecting fuel into the combustion chamber of the internal combustion engine 1 . Optionally, a single accumulator can also be assigned to the common rail system, so that, for example, a single accumulator 8 is built into the injector 7 as an additional buffer body. As a protection against impermissibly high pressure levels in the accumulator 6, a passive pressure-limiting valve 11 is provided, which opens, for example, at an accumulator pressure of 2400 bar and in the open state closes the The fuel leaks from...
