Abstract (en)

[origin: EP1273783A2] As soon as a change from an old value to a new value occurs in an amount of injected fuel, the amount supplied is immediately changed by relying on the new value of the amount for injection. The old amount for injection is still injected for a discretionary waiting time dependent on number of cylinders and transmission ratio between the high-pressure pump and an internal combustion engine. A high-pressure pump (16) pumps fuel into a pressurized reservoir (17) and a metering unit (15) for the pump to feed in an amount of fuel extracted from the reservoir and injected into an engine. Independent claims are also included for a computer program for a control device for a motor vehicle's internal combustion engine, for a control device for a motor vehicle's internal combustion engine and for a motor vehicle's internal combustion engine.
