Operating internal combustion engine involves determining time of first sign change of flywheel angular acceleration gradient from load change, generating load change compensation moment at that time

摘要

The method involves temporarily varying the engine torque when a load change reaction occurs to generate a compensating moment for the load change reaction by determining a flywheel angular acceleration time profile by differentiating the engine revolution rate and deriving the time variation of the gradient of the angular acceleration by further differentiation. The compensation moment is generated at the time of the first gradient sign change. The method involves temporarily varying the engine torque when a load change reaction occurs in order to generate a compensating moment for compensating the load change reaction. It involves determining the time profile of the angular acceleration of a flywheel by differentiating the time variation of the engine revolution rate and deriving the time variation of the gradient of the angular acceleration by further differentiation. The time of the first sign change of the gradient is determined from a load change and the compensation moment is generated at that time.
