Effects of Temperature Distribution on Operational Parameters of a Spark Ignition Engine

Abstract:

In recent years, automobile manufactures have been required to meet stringent fuel consumption specification. An important factor with regard to this problem is the operating temperature and its effect on functional parameters. In this paper, the effect of heat transfer on the various parameters such as inlet mixture temperature, compression ratio, exhaust gas, fuel consumption, lubrication oil of a spark ignition engine is studied. A number of studies have been reported which dealt with the thermal analysis of the structure of internal combustion engine. Because of the complexity of the problem, these analyses are approximate. Thus, to improve the accuracy of the results of the thermal analysis, we must work with experimental results prelevated from a 24 valve – 6 cylinder spark ignition engine. Included are comparisons between cooling characteristics of the water solutions with those of 100% ethylene glycol coolant.
