ДВИГАТЕЛЬ С ПЕРЕМЕННОЙ СТЕПЕНЬЮ СЖАТИЯ И ЧАСТОТНОЙ МОДУЛЯЦИЕЙ

摘要

A control method for the modulation of the torque of piston combustion engine that has a compression chamber ( 6 ) of variable volume and operable inlet valves ( 3 ). The torque requested for a predetermined operative condition is obtained through a selection of the volume of the compression chamber ( 6 ) combined with a selection of the time of opening and the time of closure of the inlet valves ( 3 ) combined with a selection of the frequency with which power strokes are performed.
