Abstract: An internal combustion engine for motor-vehicles, includes a system for variable actuation of the intake valves of the engine having a solenoid valve controllable between a closed condition and an open condition wherein it places a pressurized fluid chamber in communication with an exhaust chamber, with the aim of decoupling the intake valve from the respective tappet and causing the quick closing of the intake valve due to the respective return spring. The solenoid valve has a valve element with a cylindrical body having a first conical surface portion and a second conical surface portion. The conical surface portions are defined by the axially opposite ends of a circumferential groove formed on the valve element. The first conical surface portion cooperates with the valve seat. The other conical surface portion has an outer diameter substantially identical to the diameter of the annular edge defining the valve seat.

Abstract: A method for determining the bidirectional reflectance distribution function of a generally plane rough surface of a specimen made of a given material includes acquiring a refractive index of the material, the spectrum of total reflectance measured on the specimen, and the geometry of the profile of the surface. The geometry is determined by: detecting the height and approximating the surface of the specimen as a distribution of plane triangular microfaces. For each direction of incidence of the light on the surface of the specimen and for each direction of observation there is determined the angular orientation of the microfaces contributing to reflecting in a specular way the light incident in the direction of observation. The Fresnel factor defining the specular reflectance of each microface is determined. The total BRDF is determined as the sum of a Lambertian component and of a specular component.

Abstract: A process that estimates the torque transmitted by a friction clutch coupled to the shaft of a motor vehicle engine. The process includes determining the angular speed of the engine shaft and the torque developed by this shaft; calculating the difference between the measured value of the engine shaft's angular speed and an estimated value of the angular speed; and determining an estimated value of the torque transmitted by the clutch, corresponding to the calculated value of the difference or error in the engine shaft angular speed. The estimated value of the torque is used, along with the value measured or otherwise determined of the torque developed by the engine shaft, to obtain the estimated value of the angular speed of the engine shaft on the basis of a predetermined mathematical model.
