Engine Monitoring

Modern diesel engines are designed to achieve a high output at an economical cost. This normally means that these engines are lighter, have much closer tolerances than previous generation engines and often have forced induction in the form of turbochargers or super chargers. These engines must also run for extended periods at maximum power to achieve competitive production costs and reduce time-to-market factors.


In fact most modern diesel engines (also applies to LP gas & petrol) are operated close to their limits, requiring both the lubricating and cooling systems to operate at their peak – leaving little margin for error. The machine operator, of a dump truck for example, does not have the knowledge or time to evaluate the engine health status while operating the machine; instead he must focus his attention on the task at hand.


The lack of operator attention often causes a simple fault – such as low coolant level or low oil level - to escalate to a catastrophic engine failure. Operating an Engine at an excessive temperature or without enough lubrication will cause expensive engine damage and loss of production. An early warning for impending damage could instead result in simply filling the cooling system or checking the oil level – if an effective engine monitor is fitted. Thus good, effective engine monitoring is a necessity.


With more than 5000 AMS Monitors units installed in the mining, transport and materials handling industry, Autolectron is a leader in the field of engine monitors. These engine monitors have been proven to pay for themselves many times over, by providing early warning alarms and acting as a service aid. The fact is that the AMS monitor costs much less than a replacement cylinder head of a typical diesel engine.


All units will link the engine speed (RPM) to the engine oil pressure – providing pressure monitoring from idle to full load conditions and not just low end engine protection as found on some units. The units also provide a serial communication interface for PC software and interfacing to other third party systems. The AMS2000 and AMS3000 PC software programs allow the user to view engine performance in graphical form prior to an alarm, allowing the user to evaluate the cause of the alarm and follow the correct action before returning the machine back to service. The PC software also allows the user to evaluate machine usage and production cycles.
