Abstract (en)

[origin: DE10127932A1] Fuel injector comprises a valve member (3) in a housing (11) in order to provide a connection to or shut off an adjacent space. The valve member is operated by an activation element (2) with a spring element (10) that springs the valve member in a tensioning direction. The valve member has a sensor element that supplies pressure measurements in the combustion chamber into which fuel is injected. The pressure information is transferred to the valve member. Independent claims are made for a method for measuring the pressure or pressure changes in the combustion chamber of a cylinder head and transmission of such information to the valve member; and use of a piezoelectric or magnetostrictive actuator in a fuel injector either for direct or indirect operation of the valve member.
