Abstract

The motor vehicle fuel injection system (1) has injectors (5) with a pressure feed (2) for fuel and an accumulator (3) common for each injector. Between the accumulator and each injector is a fuel storage holder (4) to hold fuel under pressure. On starting, the store feeds extra fuel to the respective injector.
