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 delivering fuel from a fuel tank 2; a variable suction throttle valve 4 for influencing the fuel volume flow flowing through; A high-pressure pump 5 for fuel; an accumulator 6 for storing 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 integrated in the injector 7 as an additional damper body. As 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 turns the Fuel drains from the pressure accumulator 6 into the fuel...
