Abstract: A method for automatically emergency stopping a motor vehicle from a starting speed to a standstill by a braking device of the motor vehicle is provided. The braking device is actuated to carry out a delay profile with at least two delay phases. During a delay increase phase the delay until a threshold delay is increased and during a delay decrease phase, lasting until standstill, the delay is reduced to zero. The temporal courses of the delay are determined during the delay increase and the delay decrease at least sectionally as nth degree polynomials, where n>0, depending on the starting speed, in such a way that a stopping duration, which represents a time duration necessary for emergency stopping, does not fall below a predetermined minimum stopping duration and a distance covered during the stopping duration does not exceed a predetermined maximum stopping distance.

Abstract: The present invention relates to a system and method of calibrating a desirable engine speed for power take-off (PTO) operation. In particular, the present invention discloses having an instrument cluster unit (ICU) (102) that allows an operator to select a fourth desirable speed value for PTO operation, and a signal actuating module (SAM) (104) that may be configured to receive the value from the ICU (102) and store the value in its memory. Further, the present invention describes having a common power-train control unit (CPC) connected to the SAM (104) and configured to receive the desirable speed value from the SAM (104), and in response, modify one or more engine parameters to attain the desirable speed value for operating an engine PTO.

Abstract: A fuel injector for a combustion engine. The fuel injector includes a check valve with a return element that is a magnet, by means of which a magnetic field can be provided or is provided, such that, as a result of the decrease in pressure, a second valve element of the check valve can be moved from an open position back into a closed position and held in the closed position.

Abstract: An exhaust system of an internal combustion engine of a motor vehicle includes a particulate filter where particles are filterable out from the exhaust gas by the particulate filter. A selective catalytic reduction (SCR) catalytic converter through which the exhaust gas from the internal combustion engine is flowable for denitrifying the exhaust gas from the internal combustion engine is disposed downstream of the particulate filter. The exhaust gas of the internal combustion engine is heatable by a combustor at a point disposed upstream of the SCR catalytic converter and downstream of the particulate filter where the combustor provides an exhaust gas of the combustor. Particles are filterable out from the exhaust gas of the combustor by a filter element.

Abstract: A valve actuation device for actuating a first and second gas exchange valve of an internal combustion engine. A tilting lever is pivotable between a first starting position and a first actuation position and a valve bridge is movable between a second starting position and a second actuation position. A coupling device is switchable between a locking state, in which the valve bridge is movable out of the second starting position into the second actuation position via the coupling device by the tilting lever, and an unlocking state, in which, despite a movement of the tilting lever out of the first starting position into the first actuation position, there is no movement of the valve bridge out of the second starting position into the second actuation position. The coupling device is held on the tilting lever such that the coupling device is pivotable with the tilting lever.
