Exhaust combustion system

Abstract

Abstract DEVICES DISCLOSED FOR INCLUSION IN THE EXHAUST SYSTEM OF A VEHICLE TO ACHIEVE A MORE COMPLETE COMBYSTION OF THE EXHAUST GASES PRIOR TO ADMITTING THEM TO THE ATMOSPHERE. THE DEVICE INCLUDES AN INLET VENTURI WHICH RECEIVES THE EXHAUST GASES FROM A VEHICLE''S ENGINE AND ALSO DRAWS IN FRESH AIR FOR MIXING WITH THE EXHAUST GASES. THE DEVICE INCLUDES AN INNER LABYRINTH-CHAMBER DEFINING MEMBER AND AN OUTER SHELL SEPARATED BY A CORRUGATED STEEL SPACER. ATMOSPHERIC AIR IS FORCED THROUGH THE SPACE BETWEEN THE OUTER SHELL AND THE LABYRINTH BY THE MOTION OF THE VEHICLE FOR COOLING. THE LABYRINTH DEFINES A SERIES OF INTERCONNECTED CHAMBERS OF INCREASING CROSS SECTIONAL AREA, THE FIRST OF WHICH EXTENDS LONGITUDINALLY OF THE DEVICE AND PASSES THE EXHAUST GASES MIXED WITH FRESH AIR ADJACENT A SPARK PLUG WHICH PERIODICALLY INGINITE THE PASSING MIXTURE. A SECOND CHAMBER PASSES THE IGNITED GASES IN COUNTER CURRENT WITH RESPECT TO THE FIRST CHAMBER AND INTO A THIRD EXPANDING CHAMBER IN WHICH THE DIRECTION OF FLOW IS AGAIN REVERSED. THE COOLING AIR ENCOMPASSING THE LABYRINTH MIXES WITH THE FINAL EXHAUST GAS FROM THE THIRD EXPASION CHAMBER WHICH PASSES THROUGH A FLAME SCREEN.
