  • DEVICE FOR CONTROLLING THE OPERATING STATE OF A CATALYTIC CONVERTER OF AN EXHAUST LINE PERTAINING TO AN INTERNAL COMBUSTION ENGINE, AND ENGINE COMPRISING ONE SUCH DEVICE
    Publication number: 20090070003
    Abstract: A device for controlling an operating state of a catalytic converter of an exhaust line pertaining to an internal combustion engine. The device determines the temperature upstream of the catalytic converter, adds fuel to the exhaust line of the engine at the moment at which the temperature of the exhaust gas upstream of the catalytic converter corresponds to the ignition temperature of a catalytic converter with a normal operation, and controls the quantity of heat emitted by the reaction generated in the catalytic converter as a result of the addition of fuel. The addition device includes a dedicated fuel supply system arranged in the exhaust line of the engine upstream of the catalytic converter to be controlled.
