Title:
ガソリン熱エンジンの排ガス循環回路の制御方法、及び対応する再循環システム
Document Type and Number:
Japanese Patent JP2011528767
Kind Code:
A
Abstract:
The invention relates to a method for managing an exhaust gas recirculation circuit of a petrol thermal engine, the engine including at least one combustion chamber connected to an inlet line and an exhaust line between which extends said recirculation circuit, the recirculation circuit including a flow-rate adjustment valve, wherein said method comprises the step of adjusting flow-rate adjustment valve based on a flow-rate setpoint, said method further comprising the steps of: detecting an operation parameter representative of a pressure difference between an upstream pressure and a downstream pressure relative to the flow-rate adjustment valve, and, after comparing the parameter with a threshold corresponding to a minimum pressure difference, adjusting the flow-rate in at least one of the lines in order to increase the pressure difference.
