摘要 |
Described is a method of operating a fuel-injection device, and a fuel-injection device suitable for operation by this method, the fuel being fed in measurable amounts under high pressure to a high-pressure fuel reservoir (1) whose pressure is controlled by a pressure-control valve (9) and from which fuel is taken, through electrically controlled injector valves (14), for injection. The high-pressure reservoir is monitored for leaks by comparing the amount of fuel supplied to the reservoir by a pump (3) and the amount taken from the reservoir through the injector valves (14) and the pressure-control valve (9). If these two amounts are found to differ, a signal-generation device is triggered or action taken to modify the operation of the fuel-injection device.
