Abstract
Fuel is conveyed by at least one high-pressure pump from a low-pressure region into a high-pressure region including a pressure-accumulator line consisting of at least two separate accumulator units connected to one another by means of feed lines, and to fuel injectors for the cylinders. The accumulator units each have an accumulator volume for serving at least two cylinders, and accumulator covers provided on both end faces. All the functional units are integrated into these accumulator covers in terms of fuel delivery and transfer, and at least one separate pump accumulator is arranged in the high-pressure region between the high-pressure pump and the assembled pressure-accumulator line. The pump accumulator is connected to at least one accumulator cover of an accumulator unit of the pressure-accumulator line for fuel conveyance and is capable of being acted upon by at least one high-pressure pump.
