ABSTRACT:
A fluid monitoring arrangement1for an engine is operated in accordance with a method whereby nuclear magnetic resonance (NMR) interrogation of the fluid flow3it is possible to determine whether appropriate fluids and additives are being utilised as well as whether potential detrimental actions occur such as engine wear and carbonisation through particulate components within the flow3. Generally, an expected signal response from the fluid flow3is determined and the actual signal response compared in a comparator8with that expected signal response. Divergence in the actual signal response and in particular with regard to its profile is identified and an indication provided in a display10with regard to the potential coolant of such divergence. Normally, a reference library11is provided of expected signal responses for comparison in the comparator with the actual signal responses. The library11stores reference responses for known causes of deviation in the signal response from the NMR interrogation. Thus, by a best fit comparison a prediction as to the cause of divergence as a result of erroneous use of fluids or additives within the fluid flow3can be highlighted.
