Abstract

1334381 Regulating I. C. engine fuel injection; fuel injection pumps CAV Ltd 19 April 1971 [18 March 1970] 12927/70 Headings F1A and F1B [Also in Division G3] The excursion of a metering shuttle 22 which determines the maximum delivery of fuel pumping apparatus is set by a part 41 within a piston 36. The piston 36 is movable against spring-bias in a cylinder 37, in accordance with the output pressure of the fuel feed pump 23 which varies dependent upon pump speed. The shuttle is engageable with the contoured surface 43, 44 of the part 41 which in turn abuts a pin 45 engaging the contoured surface 47 of a member 48 movable in accordance with engine intake manifold pressure, provided by a turbo-supercharger, applied to a diaphragm 58. The axis of the contoured surface 47 is off-set from the axis of the member 48 so that the control effected by the contoured surface may be adjusted by angularly adjusting the member with member 54. The supply of fuel to the inlet 20 of the shuttle cylinder 21 through passages 25, 26, 28, 29, 30 from the feed pump 23 is controlled by a throttle 27 which may be operated by a speed governor. The surface portion 44 of the part 41 provides excess fuel for starting.
