Patent number: 10704474Abstract: Disclosed is a device for reducing the combustion instabilities of a combustion engine, this device including: an intake circuit admitting oxidizing air to the engine, a valve positioned on the engine oxidizing air intake circuit and designed to regulate the flow rate of oxidant gas admitted to the engine, an exhaust gas recirculation circuit connected to the intake circuit upstream of the oxidizing air flow rate regulating valve. The device is arranged in such a way that, at least when an injection of fuel to the engine is cut off, a minimum opening of the valve is assured so as to eliminate recirculated gases from the intake circuit.Type: GrantFiled: July 20, 2016Date of Patent: July 7, 2020Assignee: CONTINENTAL AUTOMOTIVE FRANCE S.A.S.Inventors: Florent David, Frederic Cousin, Damien Fournigault

Patent number: 8720422Abstract: The invention relates to an internal combustion heat engine, with at least one combustion chamber for intake gases comprising a mixture consisting of a fuel such as petrol and an oxidizer such as air, connected to an intake circuit (A) for the intake of said intake gases into the chamber and an exhaust circuit (B) for the exhaust of the burnt gases outside the chamber, an exhaust gas recirculation circuit (C, D) connecting the exhaust circuit to the intake circuit, and a control system for the exhaust gas recirculation. The control system is arranged so that the exhaust gas recirculation is implemented for at least one operation point defined by an engine speed and a torque output by the engine, for which the output torque is higher than 50% of the maximum engine torque. The invention can be used for operating the engine with optimal stoichiometric mixture and ignition advance without the occurrence of rattling.Type: GrantFiled: December 18, 2009Date of Patent: May 13, 2014Assignee: Valco Systemes de Controle MoteurInventors: Sebastien Potteau, Philippe Lutz, Damien Fournigault
