Patent number: 9328682Abstract: The present invention relates to a regulating strategy for a special catalytic converter for exhaust-gas aftertreatment. The catalytic converter concept is distinguished in that at least two nitrogen oxide storage catalytic converters are used in the exhaust section of a vehicle. The first, possibly close-coupled unit is followed by one or more nitrogen oxide storage catalytic converters, which are possibly situated in the underbody of the vehicle. The nitrogen oxide storage catalytic converters are then regenerated as a function of the exceedance of nitrogen oxide threshold vales downstream thereof.Type: GrantFiled: September 21, 2009Date of Patent: May 3, 2016Assignee: UMICORE AG & CO.

Patent number: 9328654Abstract: The invention relates to engine construction, in particular to systems for regulating internal combustion engines. The invention makes it possible to reduce the toxicity of exhaust gases. A four-stroke reciprocating internal combustion engine is equipped with a vacuum valve. During the discharging of the exhaust gases, a vacuum pump pumps combustion products out of the cylinder via the vacuum valve. First of all, a discharge valve is opened, and the vacuum valve is opened later, after complete (or partial) closing of the discharge valve, and the vacuum valve is closed later on or at the same time as an inlet valve opens. The vacuum valve is situated in the exhaust pipe, and an additional shut-off valve is mounted downstream of said vacuum valve, along the path of the exhaust gases, the shut-off valve connecting the exhaust pipe to the exhaust manifold or disconnecting the exhaust pipe therefrom.Type: GrantFiled: February 8, 2012Date of Patent: May 3, 2016Inventors: Aleksandr Nikolaevich Volgin, Nikolai Aleksandrovich Volgin
