Abstract

The invention is concerned with an improved fuel injection control system which is useful with an internal combustion engine comprising a pair of pluralities of equal numbers of cylinders with said pairs of pluralities of cylinders being aligned side by side and including a pair of pluralities of fuel injection pumps in one-to-one relation with said cylinders. The improved system serves to control each of the pumps to operate simultaneously and to deliver a generally equal amount of fuel to each respective cylinder. The improved control system comprises a pair of control shafts, one aligned parallel to each of the pairs of pluralities of cylinders and generally perpendicular to the axis of each of said cylinders and spaced laterally therefrom. The system further includes a pair of pluralities of fuel injector pump control link means, each of said pairs of pluralities of pump control link means being movable responsive to rotation of a respective one of said control shafts, each of said pump control link means controlling fuel injection from a respective one of said pumps to a respective corresponding cylinder. Also part of the control system is a cross shaft extending from adjacent a respective one of said control shafts to adjacent a respective other thereof, and mounted to rotate about a longitudinal axis thereof. Still further a part of the system is means for controlling rotation of the cross shaft about the longitudinal axis thereof and means communicating the cross shaft with each of the control shafts to cause an equal rotation of each of the control shafts about a longitudinal axis thereof responsive to a rotation of the cross shaft about the longitudinal axis thereof.
