A dual fuel system includes a fuel injector having a fuel pressurization plunger, and a fueling control unit structured to determine a fuel bulk modulus term based upon a volume change value (dV) and a pressure change value (dP) for a fuel pressurized in t...

A method for controlling fuel pressure in an internal combustion engine consuming a gaseous fuel and a liquid fuel comprises steps of determining a gaseous fuel pressure target value as a function of an engine operating condition; pressurizing the liquid f...

Provided is a fuel supply system for a marine structure using a high-pressure natural gas injection engine, for example, an ME-GI engine, in which boil-off gas generated in an LNG storage tank is compressed to a medium pressure, reliquefied, compressed to ...

Provided is a fuel supply system for a high-pressure natural gas injection engine having an excess boil-off gas (BOG) consumption unit, which can consume excess BOG corresponding to a difference between an amount of BOG generated in the storage tank and an...

An object of the present invention is to restrain the emission amount of unburned fuel components while restraining the consumption of fuel with relatively high ignitability in a multi-fuel internal combustion engine. The present invention resides in such ...

Provided is a fuel supply control device that performs power supply control of a shut-off valve including a first valve body that is disposed at a fuel supply path ranging from a gaseous fuel tank to a regulator and is opened in advance during power supply...

A method for controlling fuel injection in a multifuel internal-combustion engine (1); the control method envisages the steps of: receiving a request for fuel switching at a first instant (T 0 ); waiting, starting from the first instant (T 0 ), for a first...

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, a...
