摘要： An internal combustion engine operated with excess air has an exhaust gas after-treatment device wherein nitrogen oxides in the exhaust gas are reduced by selective catalytic reduction. A pump is connected between a reducing agent container and a metering device for controlled feeding of a reducing agent to the exhaust gas upstream of an SCR catalyst. A pressure accumulator with an associated pressure sensor for intermediately storing the reducing agent is connected between the pump and the metering device. The pump delivers only so much reducing agent into the pressure accumulator as is being used in the exhaust gas after-treatment.

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 which 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： A pressure sensor includes a pressure sensor element that is provided with a pressure sensor membrane. The pressure sensor element is held in a receiving part in a defined position during operation within a permissible operating pressure range by a spring element. When the permissible range is exceeded, a relative movement, acting against the spring force, between the pressure sensor element and the receiving part takes place, thereby increasing the volume of the space immediately upstream of the pressure sensor membrane. The design allows for a limitation of the pressure and for an effective protection of the pressure sensor membrane when the liquid is frozen.

摘要： Excessive NOx emission in a diesel internal combustion engine with SCR exhaust gas treatment is detected by a control unit. The excessive NOx emission value is determined from the catalytic-converter efficiency calculated for the metering of the reducing agent. In response, measures are taken, such as delayed start of the fuel injection, deactivation of a coasting cutoff, reducing an exhaust gas recirculation rate and/or increasing the idling speed. As a result, the NOx content in the untreated exhaust gas drops, the catalytic-converter temperature increases more quickly after a cold start, and the NOx emission is reduced.
