Abstract:
A multi-cylinder spark-ignition direct-injection internal combustion engine is re-fired subsequent to a fuel cutoff event wherein fuel to all cylinders is cutoff. Re-firing the engine includes selectively firing individual cylinders during re-firing engine cycles exclusively at a predetermined fixed fuel mass until all cylinders have been fired at least once, whereafter subsequent firing of individual cylinders is not limited to the predetermined fixed fuel mass.
