Latest Patents

Ehrentraut holds a patent for a "Method of operating a combustible mixture generator of an internal combustion engine." This invention focuses on producing a transition mixture enrichment during the acceleration of an engine. The system utilizes a carburettor or other mixture generator equipped with a mixing chamber, a main throttle, and a choke valve. The choke valve is operated by a quick-acting electric drive controlled by a microprocessor. This microprocessor receives signals that monitor the opening of the main throttle and other engine parameters, such as temperature and speed. When the throttle is opened, the microprocessor commands the electric drive to close the choke valve abruptly, optimizing the mixture enrichment without the need for an accelerator pump.
