Abstract

A fuel injection system for internal combustion engines in which a high pressure fuel reservoir is provided, from which fuel is supplied to injection valves in an electrically controlled manner. In order to reduce damage which occurs when there are leaks from the high pressure reservoir, the high pressure reservoir is enclosed by a sheath that can capture the emerging leakage fuel.
