Abstract

A three-dimensional computational fluid dynamics model coupled with chemical kinetics mechanism was established and validated on an actual biogas fuelled engine. Arc and kernel tracking ignition model and coherent flame combustion model were implemented and applied to capture in-cylinder ignition and turbulent combustion. On this basis, the ignition process of biogas engine was simulated and the generation and development of flame kernel was analysed. Then the single variable method was used to study the effect of ignition system parameters, such as different ignition energy, spark plug gap and initial conditions (equivalence ratio and initial temperature) on biogas engine ignition performance. The results shows that ignition process of biogas engine can be described as three stages. Spark ignition energy has little effect on ignition performance. Increasing the spark plug gap and equivalence ratio in certain range is beneficial to igniting biogas engine. Preheating the mixture will improve the ignition performance.
