Abstract
1426808 Treating exhaust gases NISSAN MOTOR CO LTD 11 May 1973 [16 May 1972 27 May 1972 5 Sept 1972] 22645/73 Heading B1W [Also in Divisions F1, F3 and F4] An I.C. engine is combined with a source 54, 82 of hydrogen peroxide, manganese dioxide or dimanganese trioxide, an exhaust system with a thermal reactor for oxidising unburnt or partially burnt exhaust gas constituents and means to supply the oxygen compound from the source or decomposition products of the oxygen compound to the engine or the exhaust system 16, 72 to facilitate oxidation of one or more constituents of the exhaust gas. In Fig. 1, hydrogen peroxide is supplied to a float chamber 60 by pump 56 and thence to venturi 26 of carburettor 24. Manganese dioxide or dimanganese trioxide may be used in suspension or injected in powder form. In Fig. 2, hydrogen peroxide is fed from source 82 to a decomposer 84 containing catalyst (96) Fig. 3 (not shown) or a glow plug (98) Fig. 4 (not shown), the resultant oxygen passing to an exhaust reactor 74, the products from there being exhausted via a premuffler 78 and a main muffler 80. The rate of supply of peroxide is controlled by a metering valve 88 in response to engine load and/or speed. Water vapour collected in condenser 100 is returned to the intake manifold via carburettor 70. The exhaust gas may be treated by injecting hydrogen peroxide to a point between the exhaust valve (104) and the reactor (74) by means of a nozzle (108) Fig. 5 (not shown). In a rotary piston engine Fig. 6, hydrogen peroxide is supplied from a source 132 via valve 136 to an injection port 144. It is timed in relation to the power phase of each working chamber. The port 144 may be disposed in the epitroohoidal surface at a location forward of the exhaust port of exhaust channel 112 in the rotational direction of rotor 116 and in this case the hydrogen peroxide injection is preferably timed in relation to the exhaust phase of each working chamber, but continuous injection of hydrogen peroxide is possible.
