Patent ID: 11255228

Abstract:
The present invention concerns a method for electrically controlling a valve actuator in a 2-stroke or 4-stroke engine, where the actuator comprises a first solenoid (A) with a plunger (5) and a second solenoid (B) with a plunger (15), wherein the engine has at least one cylinder (1) with at least one freely controllable engine valve comprising a valve disc (10) with associated valve stem (11) and a valve spring (4) and where air is introduced, or exhaust gases are evacuated from, a combustion chamber (3) past a lower part of the valve stem with the valve disc via at least one channel (2) in the cylinder, wherein the valve actuator is activatable to open the engine valve. The invention is characterized in that both the first and second solenoid are activated during opening of the engine valve.
