Abstract
A fuel injector in a fuel system having a first fuel supply of a first fuel and a second fuel supply of a second fuel includes a multifunctional control valve movable in the fuel injector to control admission of the first fuel to a combined-fuel outlet passage, and to control a timing and an injection pressure of a fuel charge containing the first fuel. In an embodiment the first fuel includes a compression-ignition fuel such as diesel and the second fuel includes an alcohol fuel such as methanol. Related apparatus and methodology is disclosed.
