Abstract

1475451 Fuel-air mixture homogenizing apparatus P AUGUST 14 Jan 1975 [22 Jan 1974] 1448/75 Heading F1B An extra air admission device for the inlet manifold of an I.C. engine comprises a member 11 located downstream of a carburetter and provided with a pair of opposing slots 3, 7 connected to an air supply and dimensioned so that air passing through them exceeds sonic velocity. During engine idling, air enters only through slot 3, while at part-load air also enters through slot 7 under control of a throttle valve (not shown) linked to a carburetter throttle valve (also not shown). Recirculated exhaust gas may also be introduced via slot 7. At full load the slot 7 is not supplied with extra air. In the modification shown in Fig. 4, the mixture is heated in a heat exchanger 59 supplied with exhaust gases. Additionally an electric heating element 58 is provided.
