Petrol Engine Fault Detection Using Mechanical Vibration Analysis

Vibration monitoring is the most widely used condition technique, where machine's vibrations are analyzed to determine incipient faults. The early detection of a fault has many advantages as detecting simple before causes too complicated problems. Every machine contains mechanical parts that emit vibration. These can be monitored and recorded reference signal, displaying it using different strategies such time domain, frequency time-frequency domain simultaneously. root mean square (RMS) method analyze signal obtain code. This paper presents method, displaying, analyzing coding vibration newly invented device called Immediate Diagnosis Device (IDD) presented by same authors detect Daewoo Lanos engine faults mobile device. A sensor (model: 333B32) was installed on body monitor at speeds 900 1500 rpm. measured fed IDD passes through series operations processing in its components assess fault. Through IDD, signals were sent unit microcontroller 32BIT- 72MHZ-12BIT ADC, Serial Interface (STM32F103C8T6) store process it. Then compares with data Microsoft Visual Studio C ++ language program, final result will displayed message screen LCD (16X2 8BIT) explain reason.
