Patent number: 11180020Abstract: The invention concerns a device (12) for controlling an air flow (F) circulating in a first heat exchanger (4) for a motor vehicle comprising at least two screens (14), the control device (12) being configured to go from a closed configuration in which the screens (14) obstruct the passage of the air flow (F) completely to an open configuration in which the screens (14) are positioned in such a manner as to allow the air flow (F) to pass with a maximum flow rate, and any intermediate configuration. According to the invention, the two screens (14) are adapted to be moved away from one another when the control device (12) goes from the closed configuration to the open configuration and to be moved toward one another when the control device (12) goes from the open configuration to the closed configuration.Type: GrantFiled: February 28, 2018Date of Patent: November 23, 2021Assignee: Valeo Systemes ThermiquesInventors: Eric Droulez, Mikhaël Preschner, Carlos Martins, Anne-Sylvie Magnier-Cathenod, Bertrand Gessier

Publication number: 20100031911Abstract: A method and a device for starting a diesel engine with no heater plugs, comprising pistons and cylinders defining combustion chambers into which gases intended to participate in combustion are admitted, in which method a strategy is adopted whereby the gases present in the chambers are heated up in such a way as to raise them to a minimum temperature within the entire volume defined by the chambers when the pistons are in the position of maximum compression or close to that position. The gases are heated by compressing the air in the cylinders using an electrical machine, or using a heating system in the intake.Type: ApplicationFiled: September 22, 2006Publication date: February 11, 2010Inventors: Bertrand Gessier, Claudiu Vasilescu, Michael Chemin, Laurent Albert, Philippe Colacicco, Yohan Comorassamy, Benoit Dupeux, Nicolas Labbe, Philippe Lutz
