Abstract
An ignition method is provided for an internal combustion engine having an engine cylinder and a remote ignition chamber in fluid communication with the main combustion chamber via a tubing assembly. The remote ignition chamber and tube are charged with a first combustible charge gas. The main combustion chamber is charged with a second combustible charge gas. A plurality of high-voltage electrodes arranged along the tube are used to pretreat the first combustible charge gas to generate radicals therein. The pretreated first combustible charge gas is ignited to produce a deflagration flame. A plurality of high-energy discharge sparkplugs arranged along the tube are used to sense a property of the deflagration flame. When the sensed property of the deflagration flame is within predetermined threshold limits, at least one of the high-energy discharge sparkplugs is used to provide a transient high energy spark to the deflagration flame to stimulate deflagration-to-detonation transition.
