An intelligent novel approach for diesel engine life monitoring using infrared image processing technic

This investigation is carried out as an effort to apply infrared thermography for assessing diesel engine life monitoring. The thermal image from engine operation is quantified via applying image processing to evaluation engine life in terms of pixel values and it is associated with engine heat release rate (HRR) and oxides of nitrogen emission (NOx). The area of cylinder head heat (CHH) from infrared image and engine life possess inverse correlation. Engine analysis was conducted on direct injection, four‐stroke, and single‐cylinder diesel engine with a constant speed of 1500 rpm and a standard compression ratio of 17.5:1 at varying engine load (W) conditions. The engine behavior and infrared (IR) image processing analysis resulting from Aegle marmelos pyrolysis oil‐diesel opus (A20) was compared with neat diesel. Engine experimental and image processing output responses reveal that A20 fuel opus is suggested to attain the enhanced engine life as compared with diesel fuel.
