Abstract

1,270,945. Electromagnetic fuel injectors; regulating fuel injection. JOSEPH LUCAS (INDUSTRIES) Ltd. July 4, 1969 [July 4, 1968; Aug. 13, 1968], Nos. 32060/68 and 38743/68. Heading F1B. Fuel from an electromagnetically operated injector 16 is mixed with air or exhaust gas flowing through a sleeve 15 surrounding the injector body. The air or exhaust gas flow is caused by the pressure difference between the manifold 13 and the air or exhaust gas inlet, e.g. the engine air cleaner or exhaust system. The downstream end of the sleeve 15 may take various forms, Figs. 2 to 5 (not shown). The air may be heated by heat exchange with the exhaust gases. The heated air or exhaust gas may pass through an annular passage (47), Fig. 4 (not shown), surrounding the flow path from the sleeve outlet orifice (41). The atomized mixture may flow from the sleeve outlet orifice 21 through a tube (55), Fig. 5 (not shown). A plurality of fuel injectors 8, Fig. 6, fed with fuel by a pump 61, have their supply pressure determined by a by-pass valve 63 subjected to the pressure of air or exhaust gas flowing to the injectors. The fuel injectors may be of the type described in Specification 1, 064, 679 and the fuel injection system may include features disclosed in Specification 1, 107, 989.
