ABSTRACT:
A fuel injection system for an internal combustion engine having a fuel supply line and at least one electromagnetically actuated fuel injection valve for metering a fuel injection quantity, which valve includes a mouthpiece fitting embodied on the valve body which protrudes into an opening in an intake tube of the engine, and the end remote from the mouthpiece fitting communicates via a fuel inflow opening with the fuel supply line. To meet hot-start conditions of the engine, the valve body is surrounded by a sheath and between the sheath and the valve body an annular chamber is formed, which extends over a substantial portion of the axial length of the valve body. Via one inflow and one outflow opening, the annular chamber is incorporated into the fuel flow in the fuel supply line.
