Description
Neshat, Imami, and Honnery build a model to predict burn timing in methane engines. Their target is the HCCI engine, which burns a uniform fuel mix under compression. Knowing when burning starts, called combustion phasing, is key to running such engines well.
Starting from a large known chemistry set, they trimmed it to 22 species and 48 reactions. Ion reactions were then added, giving 27 species and 54 reactions in total. The scheme uses ion current signals inside the cylinder to track the burn. It was built into a multi-zone engine model for testing.
