Brian J. Fregonese is an inventor associated with Fond du Lac, Wisconsin, and Brunswick Corporation. His patent work addresses how marine engines can adapt their operation to fuels with varying alcohol content.

Latest Patents

Fregonese is credited with 1 patent: “Systems and Methods for Controlling Performance of Marine Engines with Alcohol Fuels.” The invention describes a marine propulsion system with a sensor that determines the alcohol content of the fuel and a memory that stores a reference calibration for engine output. One or more controllers use the fuel’s alcohol content to modify engine parameters so the engine can perform according to at least part of that calibration. Parameters may include throttle position, spark timing, air-fuel ratio, boost pressure, exhaust gas recirculation, or camshaft timing.

Career Highlights

The available information connects Fregonese’s invention to Brunswick Corporation and the development of marine propulsion technology. The patent focuses on adjusting engine operation to accommodate alcohol fuels while maintaining performance relative to a stored calibration.
