Ignition system for reliable starting and maintaining regeneration process of diesel particulate filter

Abstract

Ignition system for reliable starting and maintaining regeneration process of Diesel particulate filer wherein the said ignition system is composed of a diesel particulate filter inside the exhaust pipe, fuel burner beside the exhaust pipe, ignition system for fuel burner, a tube for supplying the fuel, a tube for air intake, spark plug with a special arrangement of spark gap, battery as electric energy supply, an engine control unit and high voltage screened interconnection cable whereas the ignition system comprises spark plug ( 5 ) and glow plug ( 6 ) with the air gap ( 11 ) formed by central electrode ( 7 ) of spark plug ( 5 ) and glowing tip ( 8 ) of glow plug ( 6 ), grounded by fixing point ( 10 ), whereas spark is formed in mentioned spark gap ( 11 ).The ignition controller ( 1 ) consists of spark generator and glow plug controller, both placed in the same enclosure

What is claimed is: 
     
         1 . An ignition system for reliable starting and maintaining regeneration process of a diesel particulate filter inside an exhaust pipe, said ignition system comprising:
 a spark plug and a glow plug proximate the exhaust pipe and forming an air gap between a central electrode of said spark plug and a glowing tip of said glow plug; and   a fixing point acting as ground; and   wherein a spark is formed in said air gap.   
     
     
         2 . The ignition system of  claim 1 , additionally comprising an ignition controller comprising a spark generator and a glow plug controller. 
     
     
         3 . The ignition system of  claim 2  wherein both said spark generator and said glow plug controller are placed in the same enclosure. 
     
     
         4 . The ignition system of  claim 2 , wherein said ignition controller consists of a spark generator and a glow plug controller. 
     
     
         5 . The ignition system of  claim 1 , wherein spark current is below  60  mA RMS. 
     
     
         6 . A method of reliably starting and maintaining regeneration process of a diesel particulate filter inside an exhaust pipe, the method comprising:
 placing a spark plug and a glow plug proximate the exhaust pipe and forming an air gap between a central electrode of the spark plug and a glowing tip of the glow plug; and   placing a fixing point acting as ground; and   forming a spark in the air gap.   
     
     
         7 . The method of  claim 6 , additionally comprising controlling the spark via an ignition controller comprising a spark generator and a glow plug controller. 
     
     
         8 . The method of  claim 7  wherein both the spark generator and the glow plug controller are placed in the same enclosure. 
     
     
         9 . The method of  claim 7 , wherein the ignition controller consists of a spark generator and a glow plug controller. 
     
     
         10 . The method of  claim 6 , wherein spark current is below 60 mA RMS.
