Abstract : The Phase I Small Business Innovation Research completed demonstrates the feasibility of determining the cooling system performance of an engine by monitoring two temperature parameters associated with the engine system, ambient air temperature, (TA), and coolant temperature at the coolant exit point from the engine, (TB). The performance of the cooling system was computed through a proposed algorithm with real-time TA and TB as inputs. The inputs were fed into a custom-designed prototype electronic circuit that performed the computation when TB exceeded 205 F. The output of the circuit was a digital readout of the cooling system performance degradation in percent. The proposed algorithm was shown to be unsuitable for the intended purpose. However, the experimental results led to the discovery of a different algorithm which provided the indication of cooling system performance with TA and TB inputs. Keywords: Cooling system: Degradation; Indication; Temperature.
