With a total of six patents to his name, he has focused primarily on advancements in engine operation and fuel efficiency, particularly concerning flexible fuel vehicles.
Latest Patents
One of Prevost's most notable recent patents involves the operation of engines on an unknown ethanol fuel blend. This innovative vehicle controller is designed to adjust the fuel delivered to an engine when an unknown fuel type is added to a fuel tank. The controller cleverly fuels a first set of engine cylinders based on an initial fueling scheme, such as assuming that E85 fuel is utilized. Subsequently, it fuels a second set according to a different scheme, for instance, presuming that E0 fuel is present, and continues adjusting until an oxygen sensor feedback is available.
Another noteworthy patent focuses on ethanol content rationality for flexible fuel vehicles. This method enhances the accuracy of oxygen sensor-based determinations of the alcohol content in the fuel. After fueling, the system calculates two potential alcohol concentration thresholds, which are then used to test if the sensor’s readings are accurate. If discrepancies are found, necessary actions are implemented to ensure the accuracy of the alcohol concentration measurement.
