Latest Patents

One of Wollenhaupt's latest patents is an operating method for an internal combustion engine with lambda-value control. This invention relates to a method for the cylinder-selective control of an air/fuel mixture in a multi-cylinder internal combustion engine. It involves separately sensing and controlling the lambda values for different cylinders or groups of cylinders. The method allows for simultaneous control of the lambda values to different required values using an integrating I-control proportion with variable integrator slope and/or a differentiating D-control proportion. Another significant patent is a device for protecting a lambda probe. This invention addresses thermal shock reactions of a heated lambda probe caused by liquid droplets impacting the heated ceramic probe body during cold starts. The device includes a gas deflector plate arranged before the lambda probe in the exhaust gas flow, which helps to avoid fractures of the ceramic probe body and improves the representativeness of the signals transmitted by the lambda probe.
