Abstract: A method for controlling exhaust gas emission of a motor vehicle may include determining when the motor vehicle drives into a low-emission zone, wherein the low-emission zone dictates a maximum emission level for the motor vehicle; reducing actual accelerator actuation signals of the motor vehicle to effective accelerator actuation signals within the low-emission zone; and trimming an actual intake temperature of the motor vehicle, being measured with an intake temperature sensor of the motor vehicle, to an effective intake temperature when the actual intake temperature falls outside a predetermined temperature range within the low-emission zone; wherein at least one of the effective accelerator signals and the effective intake temperature are used as inputs for controlling an exhaust gas recirculation (EGR) subsystem of the motor vehicle.

Abstract: A method for determining fuel volatility and consequently performing cold starting of an internal combustion engine; in the event of cold starting, the method provides for the determination of an enrichment percentage as a function of a stored value for fuel volatility; the determination of a predicted value for starting quality before performing starting; the starting of the engine using the previously determined enrichment percentage; the determination of a measured value for starting quality; the determination of a correction value of the stored value for fuel volatility as a function of the comparison between the measured value for starting quality and the predicted value for starting quality; and the updating of the stored value for fuel volatility by applying the correction value to said stored value, so consequently modifying the amount of enrichment in force.
