A Sciemetric Signature Analysis system is used to perform the comprehensive final 'end-of-line' testing for a major manufacturer of 4.6L high performance V8 engines.
An electric motor is used to rotate the crankshaft with the engine 'cold' (i.e., not started) while the signature system records and analyzes waveform data from various sensors including torque, crankshaft angle and pressures. By comparing the waveforms and their common characteristics with those of 'good' engines, the system quickly identifies and pinpoints defects, rejecting abnormal or substandard engines.
