METHOD AND APPARATUS FOR PROCESSING AND DISPLAY OF DIESEL INJECTION WAVEFORM

摘要

A signal processing apparatus for detecting and displaying the properties of diesel fuel powered compression-ignition engines senses strain pulses in the fuel injection rail structure to perform a variety of testing functions. Among other capabilities, the apparatus permits the user to establish stroboscope timing, to measure engine RPM, to view the relationshi p between crankshaft position and injection time, and to examine the time- dependent properties of strain pulses on individual fuel injectors in order to evaluate the condition of the diesel engine.
