Title: DIRECT INJECTION SYSTEM AND METHOD
Abstract:
The disclosure describes a system (101) for pressurizing a fluid. The system (101) includes a source of liquid fuel (104), a pressure build chamber (112) in fluid communication with the source of liquid fuel (104) such that the pressure build chamber (112) is configured to receive a volume of liquid fuel from the source, wherein the pressure build chamber (112) is configured to heat a portion of the volume of liquid fuel to a sufficient temperature to convert the portion of the volume of liquid fuel into a gaseous fuel or supercritical fluid, and wherein the pressure build chamber (112) is configured to increase a pressure of a fluid in the pressure build chamber (112) to a threshold pressure to inject the gaseous fuel or supercritical fluid into an engine (102).
