| 20080276600 | Apparatus for Plasma Reaction and System for Reduction of Particulate Materials in Exhaust Gas Using the Same - A reduction system for particulate materials in exhaust gas, which is connected to a tailpipe of an engine that burns a hydrocarbon-based fuel supplied from a fuel storage tank, and collects and removes particulate materials within the exhaust gas, may include a plasma reactor having a gas inlet and an outlet, and a DPF (diesel particulate filter) trap having a filter. The tailpipe of the engine may communicate with the gas inlet of the plasma reactor, and the outlet of the plasma reactor may communicate with the DPF trap. The exhaust gas exhausted from the engine may be transferred to the DPF trap after being heated while passing through the plasma reactor. | 11-13-2008 |
| 20090031703 | PLASMA BURNER AND DIESEL PARTICULATE FILTER TRAP - A plasma burner and a diesel particulate filter (DPF) trap that can effectively oxidize and remove a particulate material (PM) within an exhaust gas by preheating fuel and mixing the fuel with the exhaust gas are provided. The DPF includes: a filter that is connected to an exhaust conduit at a side opposite to that of an engine; a plasma burner that is provided within the exhaust conduit between the engine and the filter, and that includes a fuel inlet that supplies fuel and a flame vent that projects a flame by a plasma discharge, and that heats exhaust gas; and a fuel inflow conduit that connects the fuel inlet and a fuel tank. | 02-05-2009 |
| 20100008831 | PLASMA REACTION APPARATUS, PLASMA REACTION METHOD USING THE SAME, PLASMA REACTION METHOD OF PERSISTENT GAS, AND APPARATUS FOR DECREASING NOx BY OCCLUSION CATALYST - The present invention relates to a plasma reaction apparatus and a plasma reaction method using the same. More particularly, the present invention relates to a plasma reaction apparatus which is applied to the reforming of fuel by generating rotating arc plasma and using the rotating arc being generated, the chemical treatment of a persistent gas, and the apparatus for decreasing NOx by an occlusion catalyst, and a plasma reaction method using the same. For this purpose, a raw material for a reaction is allowed to flow through an inflow hole in a swirl structure so that the raw material forms a rotating flow to progress. Accordingly, the raw material is sufficiently reacted in a plasma reaction space of a restrictive volume, and a high temperature plasma reaction is more promptly performed. Furthermore, a plasma reaction zone is expanded, prior to discharge, by a broad area chamber formed as the width of an upper part of a furnace is expanded, and plasma being generated is expanded and stayed as a pointed end spaced from an electrode at a predetermined interval is formed at an expanded end. Accordingly, the present invention relates to a plasma reaction apparatus and a plasma reaction method using the same, a plasma reaction method of a persistent gas, and an apparatus decreasing NOx by an occlusion catalyst, all of which are capable of excluding the discontinuity of the plasma reaction zone. | 01-14-2010 |

| 20090157313 | METHOD OF LOADING 3-D IMAGE DATA - The present invention relates to a method of loading 3-D image data in a navigation system. In the method, whether a vehicle enters an intersection while traveling is determined. A mask array based on a travel path of the vehicle is selected. An object to be displayed at the intersection is selected and a level-of-detail array of the object is selected according to a distance between the vehicle and the object. The level-of-detail array of the object overlaps the mask array. The object is displayed according to a level of detail of the object obtained from the level-of-detail array overlapping the mask array. According to the method, real-time 3-D image data can be loaded in a simple and efficient manner. | 06-18-2009 |
