AIR SUPERCHARGING CONTROL METHOD AND DEVICE IN INTERNAL COMBUSTION ENGINE Russian patent published in 2011 - IPC F02D41/00 F02D23/00

Abstract RU 2414618 C2

FIELD: engines and pumps.

SUBSTANCE: control method involves pressure control in inlet engine manifold as per the specified value. The above control involves slow control loop (36), quick control loop (38) and pressure limitation (40) at turbine inlet of supercharging turbine. Supercharging pressure limitation (40) is performed as soon as turbine inlet pressure exceeds the pre-determined threshold value.

EFFECT: invention provides supercharging pressure control in transient mode, in steady-state mode and pressure limitation at turbine inlet.
