SYSTEM AND METHOD FOR ESTIMATING VOLUMETRIC EFFICIENCY FOR ENGINES WITH INTAKE AND EXHAUST CAM PHASERS

摘要

An engine control module comprises a table that outputs a parked VE estimate based on an input parameter when intake and exhaust cam phasers of an engine are in a parked position. A calculation module calculates VE estimate when the intake and exhaust cam phasers are not in a parked position based on the parked VE estimate and a mathematical relationship.
