The Engine Condition Monitoring System (ECMS) is a non-intrusive condition monitoring technology that predicts engine health and defects much earlier than all other systems. This is achieved with the help of instaneous angular speed obtained by measuring speed.
How Does ECMS work?
Defects in an engine generate non-uniformity in the rotation (torsional vibration) of the crankshaft, which can be measured on the flywheel by the installation of a single non-intrusive speed sensor (a magnetic pickup sensor). This helps to assess in detail the mechanical behavior of the engine and its operating condition by diagnosing injection, compression, or valve state defaults, as well as bearing and moving parts damages.
ECMS vs. the Engine's OEM-mounted Sensors
While the installation of OEM-mounted sensors serves as a crucial safeguard, it alerts operators only once significant damage has already occurred and protects machinery from catastrophic failure. A torsional vibration-based system, on the other hand, enables early detection of emerging defects, ensuring timely maintenance actions to mitigate potential risks.
How Does It Help Pin-point the Cylinder Level Fault?
This can be achieved by adding another RPM sensor on the camshaft for identifying the top dead center (TDC) on any one of the cylinders.
