Abstract:
1. A fuel control system for controlling delivery of a primary and an alternate fuel to an internal combustion engine of a vehicle without cross-contaminating primary and alternate fuel sources with bypassed fuel from the engine, comprising: a primary fuel flow controller that controls delivery of the primary fuel from a primary fuel source to a primary fuel flow path; an alternate fuel flow controller that controls delivery of the alternate fuel from an alternate fuel source to an alternate fuel flow path; an electronic controller coupled to the primary fuel flow controller and the alternate fuel flow controller, wherein the electronic controller is adapted to control the primary fuel flow controller to control delivery of the primary fuel in the primary fuel flow path to a flow cell and control the alternate fuel flow controller to control delivery of the alternate fuel in the alternate fuel flow path to the flow cell; wherein the flow cell comprises: wherein the electronic controller is further adapted to receive RIN information comprising at least one RIN for the alternate fuel when the alternate fuel is delivered to the alternate fuel source.
