Reciprocating Engine, Overhaul and Inspection Process

Reciprocating Engine, Overhaul and Inspection Process

1. The predictive maintenance of internal combustion and internal combustion engines is based on the multichannel treatment of cylinder pressure signals, high and low frequency vibrations, ultrasound, temperature and ignition voltages.

   • Measurement synchronization is carried out with an encoder or tachometer, which serves as a piston position reference, both in compression-ignition diesel engines and in GAS engines with ignition caused by electric spark.
     • Lean fuel injection
       • Valve and segment
         • leaks
           • Wear on valve
             • kinematic chain
               • Wear and scratches
                 • Connecting rod bush
     • clearances
       • Damage to
         • crankshaft bearings
           • Turbocharger
             • problems
               • Oil and water pump
                 • problems
     • Pressure measurement in cylinders, synchronized with the crankshaft position through encoder or neutral reference tachometer Measurement of synchronized mechanical variables on the pressure pattern (vibration
       • Functional and mechanical condition report with palliative recommendations.
         • Identification of combustion and ignition problems, dynamic adjustments of valves and mechanical impacts of the reciprocating train and bench supports.
