초록 ▼

A combustor 10 for enhancing the combustion of entrained fuel or oil in the exhaust stream of an internal combustion engine is provided. The combustor 10 includes a housing 20 and an expansion chamber 60 inserted into the exhaust stream. The housing 20 forms a cylindrical combustion chamber 27 which is transected by an ignition module 30 with a combustion grill 31. The ignition module 30 includes an insulator ring 40 in which two grates 32, 34 of electrodes 50 are mounted to form the combustion grill 31. The electrodes 50 are elongate rods which extend across the open area of the insulator ring 40 to form multiple chords of varying lengths. The electrodes 50 in each grate 32, 34 are oriented such that their central axes are parallel and substantially coplanar to adjacent electrodes 50 within the same grate 32, 34. The grates 32, 34 are substantially parallel, but rotated such that the central axes of the electrodes 50 of one grate 32, 34 are perpendicular to the central axes of the electrodes of the opposing grate 32, 34 to create a lattice-type electrode 50 configuration. A cascading electrical arcing pattern and distribution among the nodes formed between various electrodes 50 is provided. The arcing between electrodes 50 of the combustion grill 31 is controlled and managed by a spark generation module 70 which includes a computer module 76 which is programmable to appropriately modify arcing variables such as voltage and switching frequency based upon feedback from sensors in the exhaust stream.

[ What is claimed is:] [1.] A combustor to heat and substantially oxidize fuel and oil entrained in the exhaust stream of an internal combustion engine, wherein the exhaust stream is conducted and flows via exhaust piping from an exhaust manifold attached to the internal combustion engine to the ambient atmosphere adjacent the end of a tailpipe of the exhaust piping, said combustor comprising in combination:a housing;said housing having a first end;said first end coupled to an upstream end of the exhaust piping nearest the exhaust manifold of the internal combustion engine;said housing having a second end opposite said first end;an expansion chamber having an intake end coupled to said second end of said housing and a downstream discharge end opposite said intake end, nearer the tailpipe of the exhaust piping;said discharge of said expansion chamber coupled to a downstream end of the exhaust piping nearer the tailpipe end of the exhaust piping;said housing including a combustion chamber;said combustion chamber having a combustion grill including a plurality of electrodes;said combustion grill substantially transecting said combustion chamber such that the exhaust stream flows over, about and through said combustion grill en route to said expansion chamber;said electrodes having a rod shape with central longitudinal axes;means to generate electric potential difference between at least two of said plurality of electrodes; andsaid electric potential difference sufficient to generate an electrical arc which travels between said at least two of said plurality of electrodes.
