System and method for delivering multiple fuel injections to a cylinder of an engine based upon engine operating conditions, the control system including an electronic controller coupled to an electronically controlled fuel injector and a plurality of sensors for inputting certain signals representative of certain engine operating conditions, the controller being operable to output a fuel injection signal to the fuel injector to deliver a first fuel shot during the intake stroke and, in one embodiment, when the cylinder piston is positioned near top dead center during the intake stroke, a second fuel shot when the cylinder piston is positioned near top dead center during the compression stroke, and a third fuel shot when the cylinder piston is positioned near top dead center during the compression stroke. The first shot fuel quantity is preferably greater than the second shot fuel quantity but preferably less than the third shot fuel quantity.

A force sensor comprising: a means for electrically isolating a first pattern of upright electrodes relative to a second pattern of upright electrodes; a means for annularly suspending the first pattern of electrodes relative to the second pattern of electrodes for motion of the first electrodes into recesses between the second electrodes by suspending a reaction mass having the first pattern of electrodes projecting therefrom from an annular ridge portion by an annular diaphragm flexure; a means for generating a capacitance between the first and second electrodes; and a means for measuring a change of capacitance as a function of a displacement of the first pattern of electrodes relative to the second pattern of electrodes. 14. The sensor of claim 13 wherein the means for suspending the first pattern of electrodes for motion relative to the second p
