Title: Innovations of Hans-Hubert Hemberger
Introduction
Hans-Hubert Hemberger is a notable inventor based in Notzingen, Germany. He has made significant contributions to the field of internal combustion engines, holding a total of 5 patents. His work focuses on improving the efficiency and functionality of diesel engines through innovative methods.
Latest Patents
One of his latest patents is a method for operating a diesel engine. This invention relates to a method where an air ratio of the fuel to be burnt and the combustion air supplied is set by a control unit according to predetermined values. When a predetermined value is recorded as a switching criterion, the control unit switches to a special operating mode for the regeneration of a catalytic converter. It sets the fuel/air ratio according to predetermined values for this operating mode. To achieve more effective regeneration of the catalytic converter, the invention provides for at least one afterinjection, which is separated in time from a main injection, of fuel that is also to be burnt during the special operating mode.
Another significant patent is for the open-loop and closed-loop control of the number and sequence of strokes in the motive process of a reciprocating-piston internal combustion engine. This method allows for leaner-than-stoichiometric combustion, where the residual oxygen not yet used for combustion can be utilized for further working strokes. A gas exchange occurs only after the residual oxygen in the combustion chamber has been completely burned or the air ratio in the combustion chamber has fallen below a lower limiting value.
