Abstract:
1. A fuel injector for heating and injecting fuel into an internal combustion engine, said fuel injector comprising: an element to control flow of fuel through said fuel injector; a heating element to heat fuel passing through said fuel injector, said heating element separate from said element that controls fuel flow through said fuel injector; and a circuit comprising said heating element and said element that controls fuel flow through said fuel injector, said circuit heating fuel passing through said fuel injector without actuating said fuel injector when current flows in a first direction and is below a predetermined level, said circuit heating fuel passing through said fuel injector and actuating said fuel injector when current flows in said first direction and is above said predetermined level, and said circuit actuating said fuel injector without substantially heating said fuel injector when current flows to said fuel injector in a second direction, said second direction different from said first direction, wherein said actuating of said fuel injector delivers fuel from the fuel injector.
