Abstract
A strain gauge transducer device externally mounted on a fuel line leading to a diesel engine and a circuit for developing engine timing signals from the transducer device output. The circuit includes a peak voltage detector to detect a peak signal from the transducer device output and a scaling potentiometer which attenuates the peak signal by a preset percentage to a level corresponding to the desired fuel pressure. A comparator compares the attenuated signal to the transducer device output and produces a timing signal when the latter is equal to or exceeds the former.
