Document Type and Number:

Japanese Patent JP2003534494

Kind Code:

A

Abstract:

A fuel injector performs main fuel injection by raising fuel pressure in a nozzle chamber to lift a check valve member to a fully open position, and performs preinjection or microinjection by operating a solid state motor to lower a check stop so that when fuel pressure in the nozzle chamber is raised the check valve member is limited to lift a much smaller distance.
