Abstract

A fuel injection arrangement (2) for a multi-cylinder combustion engine has a fuel injector (3) for each engine cylinder. A feed duct (15) which is connected to a fuel pump (5) and is common to the fuel injectors is permanently connected via a constriction (25) to a return line (23) which is common to the fuel injectors and which leads to a fuel tank (7). Venting of pressurised fuel is thus made possible.
