Control device for variable-geometry turbocharger
TLDR
In this paper, a control device for a variable-geometry turbocharger which allows adjustment of the opening of the nozzle in the turbine inlet, the basic opening target value is calculated on the basis of the actual engine rotational speed and load.Abstract:
In a control device for a variable-geometry turbocharger which allows adjustment of the opening of the nozzle in the turbine inlet, the basic opening target value of the nozzle is calculated on the basis of the actual engine rotational speed and load. The final opening target value of the nozzle is then calculated by adding a nozzle opening correction value VNta to this basic opening target value. In the calculation of this nozzle opening correction value VNta, the amount of variation ΔAc in the engine load is multiplied by a correction gain calculated on the basis of the engine rotational speed and pressure ratio, and a filter processing using a specified transmission function is performed on the resulting value ΔAc1. The amount of variation in load ΔAc2 following this filter processing is used as the input value for the calculation of the nozzle opening correction value VNta.read more
