Abstract

Official abstract text for this publication.

The present disclosure is directed to a fuel circuit of a fuel injector that includes a first channel, a second channel, and a valve. The first channel is configured to receive a first fuel and define a flow path for the first fuel. The second channel is configured to receive a second fuel and define a flow path for the second fuel. The valve is in fluid communication with the first channel and the second channel. The valve is adapted to direct the second fuel to the first channel when a pressure in the first channel reaches a predetermined level.
