The present invention relates to a system for controlling loading of an internal combustion engine based on a an adjusted load bias signal produced by an engine control computer. The engine control computer is responsive to engine speed and commanded fueling to produce a load bias signal, is responsive to engine speed, engine intake air pressure and the load bias signal to produce an acceleration-adjusted load bias value, and is responsive to engine speed, a reference engine speed and the load 10 bias signal to produce a deceleration-adjusted load bias value. The engine control computer is thereafter operable to compare the load bias value, the acceleration-adjusted load bias value and the deceleration-adjusted load bias value and produce the adjusted load bias signal as one of these three signals based on a comparison therebetween. The adjusted load bias signal is provided to an external load generator operable to control loading of the engine based thereon. Improper loading of the engine is avoided with the present invention by accounting for transient engine operation involving engine acceleration and deceleration conditions.

[ What is claimed is:] [1.]1. A system for producing an adjusted load bias signal to provide for optimal acceleration conditions for an internal combustion engine, comprising:means for sensing engine rotational speed and producing an engine speed signal corresponding thereto;means for sensing intake air pressure of an internal combustion engine and producing a boost pressure signal corresponding thereto;means for determining a load bias signal as a function of said engine speed signal; andmeans for producing an adjusted load bias signal as one of said load bias signal and an acceleration-adjusted load bias signal, said acceleration-adjusted load bias signal based on said boost pressure signal and said engine speed signal.
