Abstract
Embodiments for an internal combustion engine are provided. In one example, and internal combustion engine comprises at least two cylinders each including an injection nozzle and a fuel supply system for supplying the cylinders with fuel. The fuel supply system includes a supply line connecting each injection nozzle to a first fuel reservoir storing fuel at a first pressure, the first fuel reservoir filled by a pump provided upstream, a second fuel reservoir storing fuel at a second pressure less than the first pressure and connected to the first fuel reservoir via a connecting line for filling with fuel, and a bypass line connecting the second fuel reservoir to each injection nozzle. The bypass line opens into the fuel supply system downstream of the first fuel reservoir, thereby forming a connection point, and a shutoff element is arranged in the bypass line, opening or shutting off the bypass line.
