Pulsed jet combustion generator for premixed charge engines
Patent
·
OSTI ID:5729927
This patent describes an apparatus for generating pulsed jets comprising combustion initiating high temperature combustion products containing an appreciable amount of active radicals, for injection into compressed premixed fuel-air charges of internal combustion engines during an appropriate time interval close to the end of the compression stroke, for initiating and controlling combustion of the compressed premixed fuel-air mixture. The apparatus comprises: a body defining an interior chamber, the chamber including a terminal section defining at least one orifice for forming the jet, the body being capable of being secured to the internal combustion engine in fluid communication with the head space of a cylinder of the engine to direct the jet into the head space; a hollow electrically conductive tube secured to the body in electrically insulated relationship thereto, one first end of the hollow electrode projecting into the interior chamber, the first end being closed and defining spray perforations between the interior of the tube and the chamber.
