Embodiment Construction

[0048] figure 1 A perspective view of engine 100 is shown including fuel injector valve 102 and fuel supply valve 122 discussed below.

[0049] In some embodiments, engine 100 is a turbocharged large, low-speed two-stroke diesel engine. In some embodiments, the engine is a two-stroke marine engine. In other implementations, engine 100 may be another type and / or size of engine. exist figure 1 In the example shown in the embodiment, the engine 100 has six cylinders in line. Large turbocharged low speed two-stroke diesel engines typically have four to fourteen cylinders in-line supported by an engine frame. In some embodiments, engine 100 may be used in conjunction with another identical engine. Engine 100 may be used as the main engine or one of the main engines in an ocean going vessel. Engine 100 may be coupled to a propeller shaft of a vessel. Alternatively, the engine may be a stationary engine used to operate a generator in the power station. The total output of the...

Abstract

The present invention relates to a slurry fuel injector valve and a fuel supply valve for a slurry fuel injector valve. A fuel supply valve (502, 822) for a slurry fuel injector valve (500, 800) includes a fuel inlet (802) for fluid communication with a slurry fuel reservoir; a fuel outlet (804) for in fluid communication with the nozzle (808) of the fuel injector valve; a pump chamber port (806) for fluid communication with the pump chamber (506, 820) of the fuel injector valve; and valves (504, 875 ) movable between a first position in which the fuel inlet is in fluid communication with the pump chamber port along a first slurry fuel flow path and a second position in which A position in which the fuel outlet is in fluid communication with the pump chamber port along a second slurry fuel flow path; wherein the valve can be operated with valve actuating fluid from the engine.

Description

technical field [0001] The present invention relates to a fuel supply valve and a fuel injector valve for an engine, preferably a two-stroke marine engine. In particular, the present invention relates to fuel supply valves and fuel injector valves for non-Newtonian fuels, such as slurry fuels or emulsion fuels. Background technique [0002] Current injection technology in diesel engines employs oil-based Newtonian fuels derived from liquid hydrocarbons. This may include, but is not limited to, conventional diesel, marine diesel, marine gas oil and heavy fuel oil. [0003] In order for the fuel to burn, it needs to be pumped at high pressure into a chamber within the injector, also known as a fuel valve or fuel supply valve. Conventional fuel systems use high pressure pumps and common rail technology to deliver high pressure fuel up to one thousand bar to the fuel injectors. Thus, in conventional fuel systems, a volume of fuel is kept under high pressure. Conventional die...
