Geometric Modeling of the Frequency of an Acoustic Detonation Pressure Wave in a Standard Spark Ignition Engine

Article Preview

Abstract:

In an archetypal engine the detonation frequency is usually analyzed using an overly simplistic model, incorporating only the rudimentary parameters (modeling the combustion chamber as a right circular cylinder). The research work is to develop a broader state space geometric model to discern the detonation frequency in a standard Otto engine based on engine conformation parameters. The intent of this project is to model the detonation event using a broader state-space i.e.to build on Draper’s Acoustic Wave Pressure formula and develop a sound underlying mathematical structure manifesting the models intricacies. The mathematical structure is predicated on standard wave equation, this mathematical generality makes it a potential candidate for future investigations into developing a superposition model using acoustic wave theory.
