Abstract:
In an engine-driven vehicle, an engine power control system controlling the power output of the engine, said engine power control system comprising:(a) a fuel system including a fuel supply pump and adjustment apparatus which adjusts the rate at which fuel is delivered to combustion chambers of the engine in response to control signals supplied to an input of the adjustment apparatus, thereby to adjust power output of the engine; and (b) an electronic engine controller capable of generating, and delivering to the adjustment apparatus, a series of control signals which cause the adjustment apparatus to change the rate at which fuel is delivered to the combustion chambers thereby to change the power output of the engine, the electronic engine controller having at least one of a power curve or an algorithm for a power curve stored in memory which, responsive to certain predetermined operating conditions other than sensed engine speed, provides a sequence of pro-active change inputs, at predetermined rates of change, in quantity of fuel delivered to the engine combustion chambers, at points in time based on timing of occurrence of the respective operating conditions, thereby to produce pro-active incremental changes in power output of the engine, which pro-active incremental power changes are effected in anticipation of changes in load demand on the engine, and which pro-active incremental power changes generally correspond with expected incrementally progressive changes in load demand on the engine.
