Abstract

1275772 Controlling feed of engine exhaust gas to purifying system TOYO KOGYO CO Ltd 26 Sept 1969 [28 Sept 1968] 47478/69 Heading B1X [Also in Division F1] An I.C. engine exhaust gas purifying system includes a passage 3 Fig. 1 branched into a reactor passage 7 and a by-pass passage 8 and a jet stream from a control nozzle 9 is influenced in accordance with the proportion of unburnt component in the exhaust gas so that when the proportion is low the gas passes through the by-pass and when the proportion is greater the gas passes through the reactor. When the throttle valve 5 is closed the inlet vacuum acting on diaphragm 14 opens valve 12 and closes valve 13 so that air pumped from pump 10 passes through jet 9 to deflect the gas through the reactor passage 7. When the throttle valve 5 is open valve 12 is closed and the air passes to atmosphere through the open valve 13. The reactor may have a catalyst for reacting the unburnt component with secondary air or may be a substance to absorb an unburnt component. In a modification the air passing valve 13 (when open) is passed into the exhaust gas passage downstream of the exhaust valve. In another modification the reactor passage (7), Fig. 4 (not shown) and by-pass passage (8) are symmetrically offset from the exhaust passage and the exhaust gas stream is controlled by opposed jets (9a, 9b). In a further modification the inlet of the control jet passage (20), Fig. 5 (not shown) is inclined to the exhaust gas stream upstream of the control jet (9), the reactor passage (7) being in lime with the exhaust gas passage (3). In another embodiment air from pump 10, Fig. 6 is directed either to control jet 9 or atmosphere by vacuum-actuated valves 21, 22 controlled by solenoid valves 25, 26, one or the other of which is energized by relay 30. The latter is actuated in response to signals from intake manifold vacuum 35, coolant temperature 36, lubricant temperature 37, exhaust gas temperature 38, engine speed (by pulses from coil 41) and vehicle speed (by signals from generator 39).
