Yamaguchi, S

A fuel injection system is described for an internal combustion engine, comprising: (a) a fuel injection pump driven by the engine for fuel injection thereto and including a plunger reciprocably movable at a non-uniform speed and a control sleeve slidably fitted on the plunger; (b) first drive means operatively connected with the plunger for rotating the latter to thereby adjust the effective stroke of the plunger; (c) second drive means operatively connected with the control sleeve for displacing the latter in an axial direction to thereby adjust the pre-stroke of the control sleeve; (d) an operation sensor for detecting operating conditions of the engine; (e) a position sensor for detecting a position of the control sleeve; (f) first arithmetic means responsive to the engine operating conditions detected by the operation sensor, for computing an object injection quantity; (g) second arithmetic means responsive to the position of the control sleeve detected by the position sensor, for computing an object pre-stroke of the plunger; (h) third arithmetic means responsive to the engine operating conditions detected and the position of the control sleeve detected, for computing a correction amount; (i) first control means responsive to the correction amount computed by the third arithmetic means, for correcting the object injection quantity and for delivering a control signal to the first drive means; and (j) second control means responsive to the object injection quantity computed by the second arithmetic means, for delivering a control signal to the second drive means.
