Summary:

In this study, the effects of using of twin spark-plugs in SI engines on engine performances have been investigated theoretically .

For this purpose, by using two-zone quasi-dimensional spherical flame front approach, a thermodynamic model has been devloped. By using this model, the effects of varying spark-plugs location from center to cylinder wall on engine performances have been investigated and compared with the geometry having one spark-plug at the same locations.

It has been determined that the geometry having centrally located spark-plug gives the best performances. If spark plug is located anywhere accept from center, the using of twin spark-plugs gives better performances.

Key Words : Twin Spark-Plugs, Dual Spark-Plugs, Thermodynamic Model, SI Engine, Two-Zone Quasi-Dimensional Combustion Model
