Title: Innovations by Inventor Stefan Wixe
Introduction
Stefan Wixe is a notable inventor based in Huskvarna, Sweden. He has made significant contributions to the field of internal combustion engines, holding 2 patents that showcase his innovative approach to engine performance and efficiency.
Latest Patents
One of his latest patents focuses on the adjustment of ignition timing at cut out. This invention involves an internal combustion engine that includes a combustion chamber where a mixture of fuel and air is supplied. A spark plug is positioned near the combustion chamber to ignite this mixture, driving a piston that is operably coupled to the crank portion of the engine. The invention features a speed sensor that determines engine speed and an electronic control unit that manages the operation of the spark plug. This control unit can initiate a speed limitation operation when the engine speed reaches a cut out speed threshold and adjust ignition timing within a specific operating band of ignition angles prior to reaching this threshold. The speed limitation operation may involve skipping the application of sparks, and the control unit is designed to apply a changed ignition angle for the first spark initiated after the speed limitation operation.
Another patent by Wixe is a method for optimizing the air-fuel (A/F) ratio during acceleration in a handheld machine. This method involves comparing at least two acceleration times of different A/F ratios over defined speed intervals. Based on this comparison, the A/F ratio is adjusted to enhance engine performance during acceleration.
