SYSTEMS AND METHODS FOR AT-CYLINDER FUEL SWITCHING

Abstract: an internal combustion engine system is described herein. the systems described herein allow for switching from the methanol to the diesel as a primary fuel at the cylinder rather than at the system. a valve at an inlet of a primary return tank is used to isolate a primary return tank of a primary fuel. a primary fuel pump is deenergized allowing an input valve to open. pilot fuel is then directed into both a primary fuel input line and a pilot fuel input line into the injector.
