Abstract:
A method for adjusting the timing of an internal combustion engine having a crankshaft and a camshaft, comprising the steps of:altering the timing of the camshaft with respect to the crankshaft to optimize engine performance; determining if the engine is operating in a power enriched mode by comparing a currently delivered fuel/air mixture to a predetermined fuel/air mixture; altering the timing of the camshaft with respect to the crankshaft from the previously optimized position to adjust engine performance in response to the engine entering the power enrichment mode; determining the amount of time the engine has continuously operated within the power enrichment mode; and altering the timing of the camshaft with respect to the crankshaft from the previously altered position to reduce the thermal load on the engine.
