摘要： When determining the amount of a reducing agent solution to be introduced into the exhaust gas of a combustion system, in particular of a diesel engine, for catalytically reducing the nitrogen oxides by the SCR process, the concentration of the reducing agent in the reducing agent solution as well as the parameters characterizing the operating state of the combustion system, the exhaust gas and/or the catalyst are taken into consideration. As a result, the safety margin with respect to a theoretically optimum amount to be introduced that is required to avoid a leakage of reducing agent can be reduced, whereby the conversion rate of the nitrogen oxides is improved.

摘要： An internal combustion engine has an injection valve. A device for recording an instant at which injection starts in the injection valve includes a differentiating device connected to the injection valve for receiving current through the injection valve and emitting an output signal corresponding to a second derivative of a variation in current with respect to time. A threshold value stage is connected to the differentiating device for receiving the output signal and generating a threshold signal whenever the output signal exceeds a threshold value. A logic device is connected to the threshold value stage for recognizing the instant at which injection starts when the threshold signal occurs for a second time after a triggering instant of the injection valve.

摘要： The tank ventilation system has an adsorption vessel, a regeneration duct and a pump. The adsorption vessel captures and temporarily stores fuel vapors emerging from a fuel tank. A purge air flow can flow through the adsorption vessel. The regeneration duct connects the adsorption vessel to an intake duct. In the regeneration duct there is arranged a pump designed to draw the purge air out of the adsorption vessel and admix the purge air to intake air in the intake duct. A density of the purge air that flows in the regeneration duct is determined. Furthermore, a purge air mass flow flowing in the regeneration duct is determined as a function of the density of the purge air and a predefined pump characteristic of the pump.

摘要： An injector has a valve pin whose position is adjustable according to the pressure prevailing in a control chamber and which blocks a fluid flow through at least one injection port in a closed position. The injector has a control chamber that is hydraulically coupled to a high-pressure fluid reservoir, a piezo actuator, and a control valve which hydraulically connects and disconnects the control chamber, the piezo actuator acting upon said control valve. A combination of a triggering period for the piezo actuator and electric power that is to be fed to the piezo actuator is varied from a predefined initial combination to a target combination in which a pressure curve is detected that is characteristic of a movement of the control valve out of the closed position thereof without fluid being proportioned through the injection port.

摘要： A diaphragm pump includes a pressure sensor disposed in the housing thereof, and which is used as an expansion tank for protecting the pressure sensor. To avoid excess pressure on the pressure sensor, the pressure sensor membrane is directly disposed in the pump head, i.e., above the pump membrane of the diaphragm pump, such that the increase in volume of the reducing agent during the freezing of the reducing agent inside the diaphragm pump is detected by deflection of the pump membrane against the force of a spring, and the pressure sensor membrane is protected from damage.

摘要： To ensure the maximum possible conversion of nitrogen oxides in a DeNOx catalytic converter in an off-gas cleaning installation for reducing nitrogen oxides and, at the same time, to prevent the reducing agent which is used for the reduction from escaping into the environment, there is provision for the density of a reducing agent solution to be used to determine the volume of the reducing agent solution which is to be metered. The density is regulated in two ways, in that the temperature of the reducing agent solution is measured using a temperature sensor and set by a temperature-control device.

摘要： A tank for a vehicle having a selective catalytic reduction exhaust gas purification system operating with a reducing agent includes a fuel space for the vehicle fuel and a reducing agent space for the reducing agent. The fuel space and the reducing agent space are combined into a single structural that can be fastened as a whole to the vehicle by brackets on the structural unit. This utilizes the limited space available in any vehicle as efficiently as possible and eliminates the need to provide mounting arrangements for separate fuel and reducing agent tanks.
