FUEL INJECTION NOZZLE

摘要

A fuel injection nozzle for supplying fuel to a compression ignition engine includes a holder (13) which accommodates a spring (14) which biases the valve member (11) of the nozzle to the closed position. A spring abutment (19) abuts against a surface (18) of the holder and a blind bore (20) is formed in the holder in the vicinity of the surface. A transducer (21) is located in the bore and produces an electrical signal when an increase in the stress in the spring occurs as the valve member is moved to the open position.
