Abstract:
1. A system for electronically actuating valves in an internal combustion engine, comprising: a first voltage source; a second voltage source; plural cylinder valve actuator subsystems coupled between the first voltage source and the second voltage source, each having a valve actuator and a switch configured to selectively control application of voltage to the valve actuator to thereby selectively control energization of the valve actuator; a dissipation switch operatively coupled with the valve actuator subsystems, the dissipation switch being selectively operable to control dissipation of energy from any of the valve actuators; wherein the second voltage source is connected in parallel with the plural valve actuator subsystems; and wherein freewheel current from each of the plural valve actuator subsystems is configured to be recycled though the second voltage source and made available to any of the plural valve actuator subsystems, the second voltage source not being a battery.
