Abstract
697,249. Fuel injection systems. AKTIEBOLAGET GOTAVERKEN. March 21, 1951 [Aug. 17, 1950], No. 6800/51. Class 7 (iii) [Also in Group XXVIII] A fuel injection system, particularly for viscous fuels, comprising an injection pump of the angularly adjustable plunger type, which is supplied with heated oil under pressure, is characterised in that the plunger is arranged, when turned to the fuel cut off position, to open a passage for return flow of fuel from the supply means through the injection nozzle back to the fuel heating means. An injection pump 3, Fig. 1, feeding an injector 8 and supplied by a pump 1 with fuel heated in a heater 2, is arranged so that when set to cut-off to stop the engine its inlet and outlet 5, 6 are connected together by the plunger control groove and return pipes 10, 12 from the nozzle 8 are connected together by a groove 11 in the plunger to permit fuel to be circulated through the pump and nozzle and back through the return pipe, thus preventing congealing of the fuel in the system. If the pump 1 is engine driven, an independently driven pump 13 circulates the fuel through the system when the engine is stopped, but if the pump 1 is independently driven the pump 13 is omitted and the pipe 12 connected to the inlet of pump 1. In a modification, Fig. 4, the pipes 10, 12 are connected together at the inner end of each pump stroke by a groove 15 in the plunger, whereby a periodic flow through the pipes 10, 12 is maintained when the engine is operating. Diametrically opposed grooves 16, 17 connect the pipes 10, 12 together when the plunger is rotated to cut-off position. A second groove 15 may also connect the pipes 10, 12 together at the outer end of each pump stroke,
