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.
