ABSTRACT:
A fuel injection system for internal combustion systems is proposed, which serves to inject fuel into the intake tube of the engine. The fuel injection system includes at least one fuel injection valve which is disposed in the interior of a holder and communicates with both a fuel supply line and a fuel drainage line. The inflow of fuel into the fuel injection valve takes place radially via an inflow region. An orifice body is secured in the holder, forming a reservoir preceding the inflow region. In the first few seconds after hot starting of the engine, only the fuel stored in the reservoir reaches the inflow region and hence is injected. Because readily volatile fuel components have evaporated beforehand, the fuel stored in the reservoir enables especially good fuel preparation.
