Abstract
Implementations of the current subject-matter include systems, methods, and techniques that assist with controlling of injected fuel and spark timing across a range of operating conditions. For example, a prediction technique can be used to predict variation in combustion cylinder wall and internal metal temperatures over time, thereby enabling the likely effect of one of the calculated temperatures on airflow and hence on combustion to be assessed. The obtained information can be used to adjust fuel flow or spark timing in accordance with the predicted temperature variation from steady state conditions.
