Transient Air Flow Rate Estimation in a Natural Gas Engine Using a Nonlinear Observer

Stoichiometric air-fuel ratio control during transient operation requires an accurate estimate or measurement of the instantaneous air flow rate in an engine. Two methods are commonly used for determining engine air flow rate: air-mass sensing and conventional "speed-density." The lead air...
