20090200505CONTROL VALVE FOR CONTROLLING A GAS FLOW - The present invention relates to a control valve (08-13-2009
20100132357INTERNAL COMBUSTION ENGINE SYSTEM - The invention relates to an internal combustion engine system (06-03-2010
20100133456ACTUATION DEVICE, VALVE MEANS AND OPERATING METHOD - The present invention relates to an actuation device (06-03-2010
20100162994VALVE DEVICE AND INTERNAL COMBUSTION ENGINE SYSTEM - The present invention relates to a valve device (07-01-2010
20100180852INTERNAL COMBUSTION ENGINE - The invention relates to an internal combustion engine (07-22-2010
20100242472PISTON ENGINE - A piston engine, having at least one cylinder that includes at least a first and a second discharge valve and a double overhead camshaft for controlling the first and a second discharge valves. The double overhead camshaft includes both an inner shaft, which has at least one first cam for controlling the first discharge valve, and an outer shaft that is coaxial to the first inner shaft and has at least one second cam for controlling the second discharge valve. The inner shaft and the outer shaft are rotationally adjustable relative to one another changing the discharge time frame of the discharge valves.09-30-2010
20110000187METHOD FOR DIAGNOSING ADDITIONAL VALVES - A method for adjusting an exhaust gas recycling rate in an internal combustion engine exhaust gas recycling system, comprising: arranging the exhaust gas recycling system in at least one of a fresh gas line, an exhaust gas line, and an exhaust gas recycling line of the internal combustion engine; actuating at least one additional valve; adjusting the at least one additional valve temporarily by changing the operation of the internal combustion engine based on an exhaust gas rate associated with a current operating point of the internal combustion engine; diagnosing the at least one additional valve; and evaluating the change of at least one engine operating parameter dependent on the exhaust gas recycling rate.01-06-2011
20110139134INTERNAL COMBUSTION ENGINE SYSTEM AND ASSOCIATED OPERATING METHOD - An internal combustion engine system includes a fresh air system, an exhaust gas system and an exhaust gas recirculation system. The exhaust gas recirculation system has an exhaust gas valve assembly for controlling a removal flow at a recirculation line removal point and a fresh air valve assembly for controlling an introduction flow at a fresh air line introduction point. The exhaust gas valve assembly is permanently displaceable between a first position and a second position for generating the removal flow. The fresh air valve assembly is permanently displaceable between a first position and a second position for generating the introduction flow. The valve assemblies are synchronized such that the positive pressure pulses entering at the removal point into the recirculation line meet the negative pressure pulses at the introduction point.06-16-2011
