  "textContent": "A direct injection bi-fuel system (100) includes a first fuel subsystem (110), a second fuel subsystem (150), and a junction (124) configured to receive first fuel from the first fuel subsystem when the system is operating in a first fuel consuming mode, and to receive second fuel from the second fuel subsystem when the system is operating in a second fuel consuming mode. A pump (126) is configured to receive the fuel passing through the junction (124) and pump the fuel to a high pressure rail (180) of a combustion engine, and a purging unit (250) is configured to purge the second fuel from the rail (180) when the system is switched from the second fuel consuming mode to the first fuel consuming mode. The purging unit (258) includes a piston (258a) and is configured to receive the second fuel on one side of the piston (258a) and the first fuel on the other side of the piston (258a).",
