Abstract
A fuel injection system, for internal combustion engines in which fuel is brought to high injection pressure and distributed via magnet valves to the various fuel injection locations with the aid of a simple, unregulated high-pressure injection pump; high-pressure injection does not take place until a fuel injection quantity control valve, connected to the distribution of the high-pressure side, has closed a relief line. It thus becomes possible to vary the injection time to the maximum possible extent, without entailing major structural expense.
