ABSTRACT:
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.
