ABSTRACT:
A method is described for estimating cylinder airflow in engines that operate with manifold pressure near atmospheric pressure to compensate for degraded sensor response at such conditions. The method uses an adaptive approach that is updated under preselected engine operating conditions to thereby allow improved accuracy across a variety of engine operation.
