US 2020/0400083 A1 · FUEL EXCHANGE SYSTEM AND FUEL SUPPLY SYSTEM FOR FUEL SYSTEMS

Abstract

A system for exchanging of different fuels that can be used for operation of an engine. The system includes a fuel exchange unit, a control and an exchange return conduit. The fuel exchange unit is configured to deliver a first fuel at pressure into the injections system given a switched-off engine, in order to replace a second fuel, which is located in the injection system, with the first fuel. A fuel delivery system includes a media converter which includes a deflectable element. The media converter is driven by a drive unit via the fluid by way of the fluid being able to be led at a varying pressure to the media transformer via a first feed conduit, and is configured to deliver the fuel via a pumping effect.

Dependent claims

A system for use in a fuel facility of an engine and for the exchange of different fuels which are useable for operation of the engine,

wherein the system, via a connection, is configured to be connected onto a high-pressure region of the fuel facility supplying the engine, said high-pressure region being arranged downstream of a fuel high-pressure pump, and/or onto an injection system of the engine,
wherein the system comprises:
a fuel exchange unit,
a control, and
an exchange return conduit,
wherein the control is configured to discharge a second fuel out of the injection system via the exchange return conduit and the system is configured to autonomously deliver a first fuel at pressure from the fuel exchange unit into the injection system via the connection in order to replace the second fuel, which is located in the injection system, with the first fuel.
