Modeling the Effect of Engine Parameters on Engine Temperature during ICE Operations.

Abstract

Increasing manufacturing of more complex internal combustion engines has led to application of sophisificated computer programs in automobile industry for production and servicing. Some of these applications are modeling and simulation. These applications are also applied to heat transfer with reference to the objective of this article. A maximum of thirty three percent (33%) of total heat generated is transferred to coolant to be blown away. During operations of internal combustion engines, factors such as age, fuel type, pressure, environmental temperature, road nature, among others influenced rate of heat transfer within ICEs.Internal combustion engines are design in such a way that waste combustible gases are channeled through exhaust system. Components of the exhaust system are designed in such a way to withstand failures, stresses, vibrations and impact. In these engines, convection, radiation and conduction are modes of heat transfer through metal components and fluid. Sources of heat generation in these engines are friction within piston -cylinder liner compact and internal fuel combustion. Thus, internal combustion is the process of burning fuel with oxidizer exclusively in combustion chamber to produce heat energy. The methodology adopted involves modeling and simulation of heat equations. Thus, objectively these equations are analyzed to predict how these parameters will decrease heat generations. Graphical results obtained from applying this methodology indicate temperature reduction.
