Abstract
A fuel injection nozzle for supplying fuel to a compression ignition engine includes a holder which accommodates a spring which biases the valve member of the nozzle to the closed position. A spring abutment abuts against a surface of the holder and a blind bore is formed in the holder in the vicinity of the surface. A transducer 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.
