摘要: A system and method comprises receiving a mass air flow signal having a frequency that varies based on mass air flow in an intake manifold of an engine, determining first period data from the mass air flow signal, deriving first mass data for the mass air flow signal based on the first period data, cumulating the first period data and the first mass data for N cylinder events, wherein N is an integer greater than 1, and calculating a mass air flow between the N cylinder events from the cumulated first period data and the cumulated first mass data.
