Abstract
An injection system for an internal combustion engine has at least one injector (18) which is coupled hydraulically to a fuel accumulator (16), a prefeed pump (12) for feeding fuel from a fuel tank (10), a high pressure pump (14) which is arranged downstream behind the prefeed pump (12) for feeding the fuel into the fuel accumulator (16), and a line (42) which branches off downstream of the prefeed pump (12) and upstream of the high pressure pump (14) and is coupled hydraulically to an exhaust section injector (47), by way of which fuel can be injected into an exhaust section of the internal combustion engine.
