Abstract: The invention relates to a device (20) for assisting a driver of a vehicle to perform physical exercises, comprising:—means (21) for acquiring data representative of a driving context,—means (22) for determining a level of risk, from the acquired data,—means (23) for selecting at least one physical exercise compatible with the level of risk,—means (24) for transmitting a signal indicating to the driver the at least one selected exercise; characterised in that it further comprises—means (21?) for acquiring data representative of a history of exercises performed by said driver, said data coming from a remote storage,—and in that the means (23) for selecting at least one physical exercise also use said data representative of a history in order to select said at least one exercise.

Abstract: Device for assisting a driver of a vehicle to perform physical exercises. The invention relates to a device (20) for assisting a driver of a vehicle (15) to perform physical exercises, characterized in that it comprises: —means (21) for acquiring data representative of a driving context, —means (22) for determining a risk level on the basis of the acquired data, —means (23) for selecting at least one physical exercise compatible with the risk level, —means (24) for emitting a signal indicating the at least one selected exercise to the driver.

Abstract: The invention relates to an exhaust line of an internal combustion engine comprising: a pipe receiving exhaust gases, and a particulate filter impregnated with a first catalytic coating forming a reduction catalyst for nitrogen oxides (NOx), and with a second catalytic coating forming a first oxidation catalyst for carbon monoxide (CO) and hydrocarbons (HC). The line comprises an additional filter housed in the pipe downstream of the particulate filter and impregnated with a catalytic coating forming a second reduction catalyst for nitrogen oxides (NOx). And, the additional filter has an internal structure such that the additional filter creates a pressure drop which is less than the pressure drop created by the same volume of particulate filter impregnated with the same quantity of the same catalytic coating.

Abstract: The invention relates to a method for injecting urea in an exhaust line of an engine (1), the urea containing ammonia which is used for chemically reducing, during a selective catalytic reduction reaction, or SCR reaction, the nitrogen oxides produced by the engine, the injection being performed upstream of a catalyst (3) in which the reaction takes place, the process comprising the following steps: the temperature in the exhaust line of the engine is measured (7); an amount of urea to be injected is determined (5), from a known relation between the temperature and the amount of urea to be injected for all possible operating temperature values; a determined urea amount is injected (6) in the engine exhaust line.
