Simulation of Combustion in an Internal Combustion Engine by the Converge Code

EasyChair Preprint no. 7298

Abstract

Lately, petrol engines have undergone a remarkable evolution thanks to their outstanding performance despite the emission of polluting gases. The reheating of the Earth’s atmosphere, depletion of natural resources, and the increasing Toughening of the anti-pollution standards have pushed scientists to study seriously the physical phenomena and chemical phenomena of burning in order to decrease the emission of polluting gases through the fuel reformulation while maintaining engine performance. We begin this study with generalities on internal combustion engines. Then we will make an overview of the fuels, after that we quote the mathematical formulations as well the chemical and physical models. In the end, we present the concentrations of different polluting species: NOx, Soot Particles, unburned hydrocarbon HC and carbon monoxide CO calculated numerically using the CONVERGE code for the two fuels: iso-pentane  and heptan  engine with direct injection by introducing the chemical kinetics reactions of NO and the total reaction of oxidation of the fuel and equilibrium reactions contributing in the formation of the pollutants

Keyphrases: CONVERGE Code, Fuels and Combustion, Petrol engine, Polluting gases
