Abstract
Abstract Heated, exhaust gas is conducted through a chamber into which a protective conical housing is inserted exposing the tip of a spark plug. An ignition coil assembly is fixedly mounted within the conical housing having a high voltage contact in engagement with the spark plug to ignite the exhaust gas for pollution reducing combustion. The housing is heat resistant to protect the coil assembly from heat and a liquid spray may be directed into the heated exhaust gas.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
166 words
IN COMBINATION WITH A HEAT RESISTANT ENCLOSURE HAVING A CHAMBER THROUGH WHICH A FLOW OF HEATED EXHAUST GAS IN CONDUCTED TO ATMOSPHARE, A POLLUTION CONTROL DEVICE MOUNTED ON SAID CLOSURE AND PROJECTING INTO THE CHAMBER, COMPRISING A CONICAL HOUSING OF HEAT RESISTANT MATERIAL HAVING A BASE PORTION SUPPORTED ON THE ENCLOSURE EXTERNALLY OF THE CHAMBER AND CONVERGING TOWARD AN APEX PORTION INTERNALLY OF THE CHAMBER, AN INGITATION COIL ASSEMBLY FIXEDLY MOUNTED WITHIN THE HOUSING HAVING LOW VOLTAGE TERMINALS PROJECTING THROUGH THE BASE PORTION OF THE HOUSING EXTERNALLY THEREOF AND HIGH VOLTAGE CONTACT MEANS PROJECTING TOWARD THE APEX PORTION INTERNALLY OF THE HOUSING, A SPARK PLUG DEVICE MOUNTED IN THE APEX PORTION OF THE HOUSING HAVING AN EXPOSED TIP PROJECTING INTO THE CHAMBER AND A CONNECTOR END PORTION IN ENGAGEMENT WITH THE HIGH VOLTAGE CONTACT MEANS, AND A SOURCE OF ELECTRICAL ENERGY CONNECTED TO THE LOW VOLTAGE TERMINALS FOR PRODUCING AN IMGNITION ARC AT THE EXPOSED TIP CAUSING COMBUSTION OF THE HEATED EXHAUST GAS IN THE CHAMBER.
