Title:
METHOD AND APPARATUS FOR DETERMINING A VALVE OPERATOR POSITION
Document Type and Number:
WIPO Patent Application WO2004083692
Kind Code:
A3
Abstract:
A valve operator position is determined for an exhaust gas recirculation valve (117) for an internal combustion engine (101). The valve position may be adjusted (313) for transient engine speed conditions and/or adjusted (309) for transient engine load conditions. During high transient states, the EGR valve is closed more, to allow more air to reach the cylinders of the engine, thereby improving engine performance.
