ABSTRACT:
A fuel injection system for internal combustion engines having a high-pressure fuel pump, which supplies fuel from a low pressure chamber via a supply line into at least one high-pressure accumulation chamber. The at least one high-pressure accumulation chamber communicates via high-pressure lines with injection valves, which protrude into the combustion chamber of the engine to be supplied and whose opening and closing movements are each controlled by an electrically triggered control valve disposed in the high-pressure line at the injection valve. In order to prevent an uncontrolled escape of fuel in the event of a breach of a high-pressure line, flow limiting valves are additionally provided in all high-pressure lines, which valves close these lines when an admissible throughput quantity is exceeded.
