<p>A system and method for using vegetable oil as fuel for a diesel engine includes: a diesel fuel tank; a vegetable oil fuel tank, a supply fuel valve for switching a supply fuel output port between a diesel fuel input port and a vegetable oil fuel input port; an overflow fuel valve for switching an overflow fuel input port between a vegetable oil fuel output port and a diesel fuel output port; a fuel selector switch; and an electronic block controller. The electronic block controller is for, in response to a user changing the fuel selector switch from diesel fuel to vegetable oil fuel, waiting a predetermined amount of time to allow the vegetable oil fuel to flush the diesel fuel to the overflow fuel valve, and then setting the overflow fuel valve to direct overflow vegetable oil fuel to the vegetable oil fuel tank. Cross-contamination of the fuel tanks is avoided.</p> |
