<p>1,127,193. Treating exhaust; treating charge; air turbine plant. C. W. MORRIS. Jan. 3, 1966 [Jan. 11, 1965], No. 92/66. Headings F1B and F1G. A unit 20, comprising a turbine which drives a blower, Fig. 2 (not shown), is supplied with atmospheric air through pipe 21' via filter 15', some of the air driving the turbine and then exhausting through pipe 23' to a low pressure region of an I. C. engine induction system, whilst the rest of the air is pumped by the blower through pipe 22' to the engine exhaust system - either to the exhaust manifold, or to the exhaust pipe, or to an exhaust afterburner 50. In the latter case, if the temperature in the afterburner exceeds a certain value, a temperature - responsive valve, Fig. 8 (not shown), opens to put pipes 21" and 29 into communication so that some of the air passing through the filter 15' by-passes the unit 20 and is supplied to the pipe 23' thus reducing the pressure differential across the turbine and therefore its speed, reducing the air supply to the afterburner, and weakening the mixture supplied to the cylinders. The air supply to the turbine part of unit 20 may be restricted, or a metering orifice may be provided in a fitting 63 between the pipe 23' and the unit 20 downstream of the junction with pipe 29, Fig. 7 (not shown).</p> |
