Abstract
The invention relates to a system for igniting a fuel-air mixture in a combustion chamber with a corona discharge. The system comprises an electrode inside of the combustion chamber, an electric circuit which provides radio frequency electric power to the electrode, and a ground formed by the combustion chamber walls. A radio frequency voltage differential formed between the electrode and the ground produces a radio frequency electric field therebetween which causes a fuel-air mixture to ionize resulting in combustion of the fuel-air mixture. The system can be utilized in engines such as internal combustion engines or gas turbine engines, for example.
