Title:

METHOD FOR OPERATING FUEL INJECTION SYSTEM USED FOR INTERNAL COMBUSTION ENGINE

Document Type and Number:

Japanese Patent JP2004011642

Kind Code:

A

Abstract:

To remarkably reduce the difference in injection quantity among various different injectors in one operation cycle.

This method comprises calculating the start and end of injection in relation to the operating state of an internal combustion engine and a load request; calculating the period TFoerder of force feed state of a high-pressure pump; and controlling a quantity control valve so that the force feed stage of the high-pressure pump is symmetrically arranged to the start and end of injection.
