1411573 Treating exhaust gas REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 20 Dec 1972 [28 Dec 1971] 58774/72 Heading B1W I.C. engine exhaust gas treating system consists of a reducing catalytic reactor and an oxidising catalytic reactor in series, each reactor being supplied at its upstream end with a variable amount of air and is characterised in that the air is provided by a pump capable of delivering an amount of air at least twice as great as that required for complete combustion of the carbon monoxide present in the exhaust gas of the engine, and the flow to each reactor is controlled by a common distributor means which in turn is controlled by thermostatic means responsive to the reactor temperatures, such that a conduit supplies to the exhaust manifold, at the outlet of each cylinder, an amount of air slightly less than that required for stoichiometric combustion of all the combustible substances in the exhaust gas .... and air is also supplied to a distributor having four outlets, two of said outlets being restricted and each supplying a respective reactor, an outlet for venting excess air to atmosphere and a high-output outlet connected to the inlet of the oxidising reactor. An engine 1 drives a pump 7 which supplies air to a gallery 8 which feeds air to nozzles 9 at the exhaust outlets of the cylinders. The exhaust manifold 2 is connected to a casing 3 which contains a reducing reactor 4 and an oxidising reactor 6 separated by a space 5. The temperature of the reactors is sensed by probes 23 and 24 respectively. The pump also supplies air to a distributor 11 having four outlets controlled by two spool valves 16 and 17 mounted on a common spindle 18, and biassed by springs 21 and 22 to the position shown on the Figure. When the engine is started from cold the reducing reactor 4 is operated as an oxidising reactor in order to quickly heat it to the temperature at which it begins to function as a reducing reactor. To achieve this, air from the restricted outlet 12 is fed into the upstream end of the reactor, excess air being exhausted through the vent 14. When the reactor reaches its working temperature, the probe 23 produces a signal which causes the relay 25 to operate, which energises the solenoid 19 and moves the spindle 18, against the spring 21 to the position 16 1 and 17 1 . The supply of air to the reactor 4 ceases and air is supplied to the space 5 from the restricted outlet 13, the excess air vent 14 remaining open. If the reactor 6 exceeds its safe working temperature, the probe 24, through relay 26 energises the solenoid 20 and pulls the spindle 18 to the position 16 2 and 17 2 , which opens the high output outlet 15 and closes the vent 14. The flow of air is then sufficient to cool the reactor 6.
