Abstract

1,212,898. I.C. engine exhaust systems. G.L. SCHNURMACHER. Nov.22, 1968 [Nov.24, 1967], No.55448/68. Heading F1B. A vehicle I.C. engine comprises an exhaust passage leading to atmosphere from an exhaust manifold, a stream of air from an electric blower being heated by an electric heater element and directed into the exhaust passage to vaporize liquid in the passage and carry it along the passage to the atmosphere, and a temperature-responsive switch to energize the blower and heater element when the temperature of the exhaust fluids is below the level at which the liquid is vaporized. When ignition switch 26 is moved to the ON position, capacitor 29 is charged slowly through a resistor 28 to provide a time delay before a relay 37, 41 energizes a blower 17 and a heater element 18 located in a duct 22 communicating with the exhaust pipe 13. The time delay allows the starter motor 24 to be operated by means of the starter switch 27 before the battery has to supply power to the blower 17 and heater element 18. The hot air discharged from the duct 22 into the exhaust pipe 13 vaporizes liquids occurring in the exhaust pipe during cold running of the engine. A switch 39 actuated by a temperature-responsive bi-metallic element 36 in the tailpipe 16 de-energizes the blower 17 and heater element 18 when the temperature is sufficient to ensure vaporization. When the ignition switch is turned to the OFF position, the capacitor 29 discharges slowly through a resistor 43 to provide a time delay before the relay 37, 41 drops out, whereby if the blower 17 and heater element 18 are still energized they will remain energized for a short time to discharge any lingering vapours from the exhaust system.
