The Nonlinear Multi-Fuel Combustion Equation: Comparison between the Model of Heat in SIE for Ethanol-Gasoline Blended and High Order Iteration Method

Abstract:

A quasi one-dimensional engine cycle, the simulation program was developed to predict the simple heat transfer during combustion stroke in a spark ignition engine (SIE) of ethanol-gasoline blended fuels. A two-zone heat release model was utilized to model the combustion process inside the combustion cylinder by using high order iteration method (HIM) in combustion equation. The fuel, air and burned gas properties throughout the engine cycle were calculated by using variable specific heats. The transient heat flux inside the combustion chamber due to the change in the cylinder gas temperature and pressure during combustion was determined by using the constant of heat rate from enthalpy heat rate coefficient. The program was written in MATLAB. The results of this paper such as the average heat flux cycles of the burned gas during the combustion and showing the emissions of at during the combustion process by high iteration method. Based on these results, it was concluded that the fundamental thermodynamic properties of the fuel, air, and combustion product species were in agreement with previously published results to within the scatter of those results typically less than 1% form references 1%. The combustion products were calculated by the high order iteration methods by around 1% from the old methods.
