    Abstract: A device is provided for producing and/or augmenting a partial vacuum in a motor vehicle, in particular for operating a partial vacuum brake servo-unit. The device includes, but is not limited to a throttle unit, which has at least one throttle valve housing and a throttle valve which is arranged so as to be rotatable in an angle range in a throttle channel in the throttle valve housing for controlling a fluid flow in the throttle channel. The device also includes, but is not limited to means for producing and/or augmenting partial vacuum, the means being configured as partial vacuum augmentation means integrated into the throttle valve housing, which partial vacuum augmentation means act according to Bernoulli's principle in the manner of a sucking jet pump to produce an augmented partial vacuum for at least one brake servo-unit. The means are configured as at least one control bore extending through the throttle valve housing, wherein the control bore opens in the throttle channel in an opening to produce a partial vacuum in the control bore and the control bore is set in the drag direction at a setting angle α>0° measured with respect to the cross-sectional plane of the throttle channel.

    Abstract: The aim of the invention is to estimate a temperature jump (ΔT) of a catalytic converter of an internal combustion engine in the event of a change in the composition of the exhaust gas. To this end, a quantity of a reactand (SI) stored in the catalytic converter is monitored (2-7), and the heating (ΔT) of the catalytic converter resulting from the reaction heat released during the reaction of the stored reactand is assumed (13, 14, 16, 17) as the temperature jump (ΔT).
