Abstract

An arrangement for and a method of detecting a beginning of injection in an internal combustion engine wherein an injection pressure is sensed by a pressure transducer and a pressure signal generated thereby is compared with a threshold pressure signal which is formed from a peak value of the injection pressure signal of the preceding injection period, and an injection signal is generated when the injection pressure exceeds the threshold pressure.
