Abstract: A road vehicle comprising: an internal combustion engine; an electric starter motor; a high-voltage electric circuit provided with a first storage system; a low-voltage electric circuit provided with a second storage system and directly connected to the electric starter motor; an electronic DC-DC power converter, which connects the low-voltage electric circuit and the high-voltage electric circuit to one another; and a control unit configured, in the presence of a turned-on condition of the road vehicle and when the internal combustion engine is off, to activate the electronic DC-DC power converter so as to transfer power to be at least partially supplied to the electric starter motor from the high-voltage electric circuit to the low-voltage electric circuit only in case of a cold-start condition of the internal combustion engine.

Abstract: A method to adjust an internal combustion engine is described, comprising the steps of: i) controlling a first and second adjustment member so as to adjust a first and second quantity of air in a first and second cylinder provided with a first and second piston; ii) operating a first and second ignition member with a first and second advance angle relative to the first and second top dead centre of the first and second piston; iii) processing a value of one of the amplitudes associated with a respective frequency of a driving member; iv) detecting that the amplitude at a corresponding desired frequency exceeds a threshold value; v) reducing the first advance angle; and vi) increasing the first quantity of air so as to maintain the average value of the resulting torque constant at two complete rotations of said driving member.
