Title: Innovator Spotlight: David Darin Wickman
Introduction
David Darin Wickman is a notable inventor based in Madison, Wisconsin, known for his innovative contributions to the field of internal combustion engines. With a total of five patents to his name, Wickman has focused on advancements that aim to improve fuel efficiency and promote the use of alternative fuels, particularly biofuels.
Latest Patents
Wickman's most recent patents include groundbreaking technologies such as the "Wet Biofuel Compression Ignition" system. This compression ignition engine utilizes hydrous biofuels, which can contain a water content of 20-85%. By pressurizing and heating the hydrous fuel through the engine's exhaust gases, this system is able to inject it into the engine cylinder near the top dead center, yielding a dramatic brake thermal efficiency increase of 20% or more compared to conventional diesel engines.
Another of Wickman’s notable inventions is the "Supercritical Reforming of Fuels Without Separate Water Supply" for internal combustion engines. This innovative engine-reformer system transforms a specified fuel into syngas, which is then used to fuel an internal combustion engine. The system maintains the first fuel in a supercritical state during reforming, allowing for the injection of supercritical syngas into the engine to mitigate autoignition issues commonly associated with gaseous syngas. This pioneering technology allows the utilization of wet fuels such as hydrous ethanol, thereby reducing fuel production and operation costs.
