Problems solved by technology

Third, with the engine stopped, the fuel oil tends to solidify, making it difficult (if not impossible) for the device that controls the sleeve setting to work
Therefore, the fuel injection pump described in EP0537911B1 also has the same problem as the fuel injection pump in GB2260374A

Embodiment Construction

[0026] figure 1 A block schematic diagram of an exemplary embodiment of a fuel injection system 100 configured to supply fuel, such as heavy fuel oil, to nozzles 105 of a large internal combustion engine 5 is shown. According to this exemplary embodiment of fuel injection system 100 , each nozzle 105 may be connected to an associated fuel injection pump 110 via a high pressure fuel line 115 . Alternatively, one fuel injection pump 110 may be configured to supply fuel, such as heavy fuel oil, to multiple fuel nozzles 105 .

[0027] Each fuel injection pump 110 may be connected to a fuel reservoir 120 via a fuel supply line 116 . Additionally, each fuel injection pump 110 may be connected to a flushing system 125 via a flushing fluid supply line 111 . In other exemplary embodiments of the present invention, the figure 1 The arrangement shown is modified in that only one high-pressure fuel pump is provided instead of several pumps 110 . The one high pressure fuel pump may be ...

Abstract

The invention relates to a fuel injection system (100) configured to supply fuel, such as heavy fuel oil, to a nozzle (105) of a large internal combustion engine (5). The fuel injection system may include a fuel injection pump (110) configured to meter the correct amount of fuel, such as heavy fuel oil, to inject, generate high pressure, and deliver fuel to the large internal combustion engine (5) at the appropriate time at least one nozzle (105). The fuel injection pump (110) may include: a pump barrel (10) extending longitudinally and having a barrel inner wall (12); a piston (13) configured to reciprocate within the pump barrel (10) , and guided by the barrel inner wall (12); and a first groove (38), which is formed in the barrel inner wall (12) at a first position relative to the longitudinal direction, and is always guided by the reciprocating motion The piston (13) covers. A flushing system (125) may be provided connected to said first gutter (38). The irrigation system (125) may be configured to supply irrigation fluid through the first channel (38).

Description

technical field [0001] The present invention generally relates to a fuel injection system for supplying fuel, such as heavy fuel oil, to nozzles of large internal combustion engines. Furthermore, the invention relates to a fuel injection pump and a method of flushing a fuel injection pump configured to pump fuel of a large internal combustion engine, such as heavy fuel oil. [0002] Furthermore, the invention relates to a high-pressure fuel pump for supplying fuel, such as heavy fuel oil, to a common rail of a fuel injection system, the invention relates to a fuel pump, and a method of flushing a fuel pump configured Fuel for pumping large internal combustion engines, such as heavy fuel oil. Background technique [0003] In general, the term "large internal combustion engine" may refer to an internal combustion engine that may be used as the main or secondary engine on ships / vessels such as cruise ships, cargo ships, container ships and tankers, or on power stations for gen...
