Title: Method and an apparatus to control the temperature of an engine exhaust gas purifying device
IPC: F02D41/34
Filed: 1976-05-17
Abstract: 1500882 Regulating IC engines; spray carburetters NISSAN MOTOR CO Ltd 17 May 1976 [16 May 1975] 20236/76 Headings F1B and F1H [Also in Divisions Bl F4 and G3] The combustion temperature in an exhaust gas purifying device 46 is maintained within a predetermined temperature range by means of an air/ fuel ratio control device 60 which comprises sensor 68 which generates a signal representative of the combustion temperature, a control circuit 70 in which the generated signal is compared with first and second reference signals representative of the minimum and maximum of the predetermined range and which generates a first error signal when the temperature is too low and a second error signal when the temperature is too high and means responsive to the first error signal to reduce the air/fuel ratio of mixture to be burned in the combustion chamber of an engine; and means responsive to the second error signal to increase the air/ fuel ratio of the mixture.  Carburetter 20 has a main nozzle 28, an associated air bleed 32 and a supplementary air inlet 76 controlled by solenoid valve 80. Slow running part 36 has an air bleed 38 and supplementary air inlet 78 controlled by solenoid valve 82. When the temperature in chamber 46 is too low, both valves 80 and 82 close, to increase the amount of unburnt fuel which reaches chamber 46, and thereby increase the chamber temperature. Conversely, when the temperature in chamber 46 is too high, both the valves open. Exhaust gas recirculation. Conduit 50 conducts exhaust gas from pipe 42 to inlet passage 16 at a rate controlled by diaphragm-operated valve 54, the vacumn chamber of which is connected to inlet passage 16 downstream of throttle valve 21 so that exhaust gas recirculation increases with increases in inlet passage vacuum. Ignition timing control. Distributer unit 98 includes a first set of contact breaker points 96 which time the engine for normal running and a second set of points 108, electrically in parallel with the first set which provide for the spark to occur later than the first set. In series with second points 108 is switch 106 which is closed by control circuit 70 when chamber 46 is at too low a temperature, to retard the spark and thus increase the temperature of exhaust gases reaching chamber 46. Secondary air supply to afterburner. Enginedriven pump 64 feeds air to control valve 116, which directs air to pipe 44 upstream of chamber 46 when control circuit 70 produces the first error signal indicating that the temperature of chamber 46 is too low. When circuit 70 produces the second error signal, valve 116 is actuated to divert the pump output to duct 118 leading to air cleaner 18. Afterburner ignition device. A spark-plug 120 receives a high voltage from generator 122 when the first error signal is produced by circuit 70. Operation of the generator ceases when the second error signal is produced.

Patent GB-202671-A (GB)
Abstract: 202,671. Leffler, F. H., and Barton, A. C. Feb. 3, 1923. Pneumatic actuation.-In a combination of two fluid-operated switches or cut-outs one operated by negative or positive air or gas pressure and the other bv oil or liquid pressure both pressures being consequent upon the operation of an internal combustion engine, the two switches are introduced in parallel in one circuit e.g. the ignition circuit whereby one switch as cut-out is adapted to support or confirm the other, and they may also control other circuits e.g. the dynamo charging circuit. The gas pressure cut-out consists of a piston 2 working in a cylinder 4 and arranged to be pressed upwards by a spring 16. The reduced projecting upper end 17 of the piston 2 carries a square insulating block 18 containing two pairs of interconnected spring plunger contacts 19, 21 and 20, 22 adapted to bridge fixed contacts in two sides of a rectangular cavity of insulating material. The oil cut-out comprises a piston in a cylinder 3 connected through an orifice 23 with the lubricating system, the piston 1 carrying pairs of contacts 12, 13 and 11, 14 in an insulating block 10 secured to the upper reduced end 9 of the piston, which is pressed downwards by springs 6. The piston 1 has a transverse passage 7 arranged when it is in its inoperative pcsition to complete the passage 8, 5, 15 between the gas cut-out and the engine induction pipe and to render the gas cut-out inoperative when the oil piston is raised. The electrical connections to the fixed contacts are shown in Fig. 3, a, b being connected in the ignition circuit and c, b in the dynamo to battery circuit. On starting the engine the suction of the engine draws down the piston 2 to complete the ignition circuit through contacts 28, 30 and when the oil pressure rises sufficiently to raise the piston 1 the ignition circuit is broken through these contacts 2 and remade through the parallel path through contacts 24, 26. At the same time the dynamo charging circuit c, d is completed through the following path : fixed contact 25, movable contacts 12, 13, fixed contacts 27, 31 which are electrically connected together, movable contacts 20, 22 and fixed contact 28. When the speed of the engine falls to a predetermined value the consequently reduced oil pressure fails to maintain the pistou 1 in its raised position so that the gas cut-out is then brcught into operation again the ignition circuit being finally broken when the engine stops. The oil pressure cut-out may, alternatively, be operated by pressure from the cooling water system and the gas cut-out by the positive pressure due to an air or gas compressor driven by the engine, the cut-outs alternatively being of the flexible diaphragm type. The switch or push of an electric engine starter may be adapted to move either piston to ensure contact in the ignition circuit for starting.
