Title:
METHOD AND DEVICE FOR PROCESSING SIGNAL FROM MEASURING SENSOR OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS59110846
Kind Code:
A
Abstract:
A method for evaluating output signals of a sensor for measuring operational parameters of an internal combustion engine, utilizes characteristic wave forms of signal portions derived from a sensor. Threshold levels for setting the beginning and the end of an injection process are determined from threshold levels of an (n+m)th signal portion which are derived from a fraction of preceding nth signal. The device for carrying out this method includes a store for the peak value of the nth signal and a controlled discharging device which cooperates with a threshold switch and which is controlled by other parameters of the engine such as rotary speed.
