Abstract

1421367 Fuel injection to IC engines; combustion chambers; injection nozzles McCULLOCH CORP 25 April 1973 [5 July 1972] 19627/73 Heading F1B Fuel injection apparatus for I.C. engines comprises a pump 100 from which fuel is supplied via a passage 102 to a nozzle 101, the flow-rate under some operating conditions from the pump into the passage 102 being greater than that from the passage to the nozzle 101, the fuel flow per engine working stroke from pump to passage and the amount of fuel diverted from the passage (i.e. not reaching the nozzle) being greater at low engine speeds than high for a given load. The amount of fuel supplied to the passage 102 by the pump 100 is determined by regulating the displacement volume of the pump in response to engine speed and the proportion of fuel diverted is determined by a valve 109 the opening of which (if any) is determined by the throttle position. The fuel injected into the combustion chamber from nozzle 101 emerges from the nozzle in discrete streams except under idling conditions, when the fuel streams are more diffuse. The form of these streams is determined by the amount the nozzle valve opens, Figs. 8 and 9 (not shown). The discrete streams are directed to agitation zones 105 Fig. 1 and 25 Fig. 3 and combustion occurs in discrete regions of burning 106 Fig. 1 and 30 Figs. 4 and 5, (not shown). The invention is applied to an I.C. engine 1 Fig. 2 having a working cylinder 2 to which combustion air is supplied by an air pumping cylinder 3 via conduit 10. Fuel is supplied by a pump 15 to a nozzle 17 which discharges in pre-combustion chamber or cavity 19. A valve 109 may be included in the conduit from a fuel pump to each injection nozzle of a multicylinder engine or a single valve 109 may be used with a conventional multiple output rotary fuel pump shown in Fig. 6. Fuel passes to pumping chamber 203 from a passage 203a connected to a fuel source via a metering valve (e.g. 123 in Fig. 1) and is pumped from chamber 203 by pistons 202 during rotation of a rotor 201. The fuel leaves the pump via a passage 205 and sequentially via output flow-paths 206. The valve 109 is connected to the distribution passage 205 via passage 112, groove 207 and passage 208.
