摘要： An in-cylinder pressure sensor obtains a high resolution pressure curve for each cylinder cycle allowing the various data to be derived for improved monitoring and control of operation of the engine. A more accurate measure of work done by the engine is obtained allowing more accurate estimation of the vehicle torque and hence real torque control. In addition engine losses can be more accurately calculated and the estimates corrected yet further by obtaining an accurate top dead centre position for the engine cylinders.

摘要： A method for the control of an electromagnetic actuator coupled to a respective valve and provided with a moving member actuated magnetically, by means of a net force, in order to control the movement of the valve between a closed position and a position of maximum opening, a pair of electromagnets disposed on opposite sides with respect to the moving member and an elastic member adapted to maintain the valve in a rest position. The method comprises the stages of estimating the disturbing forces acting on the valve, calculating an actual force as a function of the objective force value and the disturbing forces and implementing this actual force value.

摘要： Method for protection against overheating of electromagnetic actuators for actuation of intake and exhaust valves in internal-combustion engines, in which an actuator of an engine is connected to a respective intake or exhaust valve, and includes a mobile unit which is actuated magnetically, in order to control the movement of the said valve, and a first and a second electromagnet, which are disposed on opposite sides of the mobile unit; the actuator also being connected to a control unit, via a piloting circuit, which supplies at least one current to a current-measuring circuit, which supplies to the control unit measured values of the current. The method includes the steps of: estimating for each first and second electromagnet, a temperature value TK+1 which is updated on the basis of a present temperature value TK and of the measured values of the current; checking whether the updated temperature value TK is lower than a threshold; and implementing protective action, if the updated temperature value TK is higher than the first threshold.
