摘要： An estimation method to determine the concentration of recirculated exhaust gas present in a cylinder (2) of an internal combustion engine (1); the concentrations (%EGR) of recirculated exhaust gas in a gas mixture flowing through an intake duct (6) are periodically stored in a buffer (30); a first instant (T 1 ) is determined, in which a programming of a following combustion in the cylinder (2) is carried out; an advance time (T pred ) is determined, which elapses between the first instant (T 1 ) and a second instant (T 2 ) in the future, in which air will be taken into the cylinder for the following combustion in the cylinder (2); a transport time (T TR ) is determined; a third instant (T 3 ) in the past is determined by subtracting from the first instant (T 1 ) an amount of time which is equal to the difference between the transport time (T TR ) and the advance time (T pred ); and the concentration of recirculated exhaust gas present in the cylinder (2) in the second instant is estimated depending on a concentration (%EGR) of recirculated exhaust gas contained in the buffer (30) and corresponding to the third instant (T 3 ).

摘要： An actuator (4) comprising a main body (8) which delimits a kinematic chamber (12) inside which a valve (16) and/or a relative drive mechanism (20) of the valve (16) is at least partially housed, a closing lid (24) that can be associated to close the kinematic chamber (12) of the main body (8), wherein the throttle body (4) contains a position sensor (28), of the magnetic or magnetoresistive type, facing a slider (30) of the valve (16) and/or a component of said drive mechanism (20) so as to read the position of said slider (30) and therefore of the relative valve (16) and/or of the relative component of the drive mechanism (20). Advantageously, the closing lid (24) is provided with a screening device (36) of electromagnetic fields for the position sensor (28) and the slider (30), positioned near the position sensor (28), on the side opposite the kinematic chamber (12) with respect to the position sensor (28).

摘要： A method for managing and controlling the operation of a hybrid propulsion system 1, comprising at least one electric powertrain 2 and a thermal powertrain 3, is described.
The method comprises a step of storing, in a control unit 5 of the propulsion system 1, digital data organized in a first table (Trq_SYSH_map) configured to provide an electric powertrain optimum torque value (EM-Trq-Opt) adapted to maximize the total efficiency (EffSysH) of the propulsion system, as a function of operative parameters of the propulsion system (torque Td and revolutions per minute RPMd, referred to a common reference point 4, and gear); moreover, a step of storing, in the control unit 5 of the propulsion system, further digital data organized in a second table (EFF_SYST_map) configured to supply a thermal powertrain efficiency value (EffSysT) as a function of the aforesaid operative parameters.
During the operation of the hybrid propulsion system 1, at every required operative condition, expressed through the aforesaid operative parameters of the propulsion system, the method comprises the following further steps, carried out by the control unit 5 of the propulsion system: determining, as a function of the required operative condition, the efficiency of the thermal powertrain (EffSysT) based on the second table (EFF_SYST_map); detecting a current State of Charge (SOC) value of a battery (21) comprised in the hybrid propulsion system; determining, as a function of the detected State of Charge (SOC), an operative control threshold, represented by a thermal propulsion threshold efficiency value (Eff_T_THR), based on a predetermined ratio (f) in which the operative control threshold (Eff_T_THR) increases as the State of Charge (SOC) increases.
The method then provides comparing the efficiency of the thermal powertrain (EffSysT) with the operative control threshold (Eff_T_THR).
If the determined efficiency of the thermal powertrain is higher than the operative control threshold (Eff_T_THR), the method includes switching off the electric powertrain 2 and commanding the activation of the thermal powertrain 3.
If the determined efficiency of the thermal powertrain (EffSysT) is lower than the operative control threshold (Eff_T_THR), the method includes commanding the activation of the electric powertrain 2, so that the electric powertrain 2 works with the stored value of electric powertrain optimum torque (EM-Trq-Opt) corresponding to the required operative condition.
