Problems solved by technology

This makes waterborne slurries less susceptible to atomization which can cause increased ignition delay and incomplete combustion which can lead to engine misfires, seal damage and reduced engine life
Additionally, such deposits and agglomerations can hinder or prevent the proper operation of the fuel injector system and in some cases can cause blockages in the fuel injector system

Embodiment Construction

[0034] figure 1 A perspective view of the engine 100 is shown, figure 2 A fuel injector valve 200 shown in and discussed below may be used with engine 100 .

[0035] In this embodiment, the engine 100 is a turbocharged large, low speed two-stroke engine. exist figure 1 In the preferred embodiment, the engine 100 has six cylinders in line. Turbocharged, large, low-speed two-stroke engines typically have four to fourteen cylinders in-line supported by an engine frame. In some embodiments, engine 100 is used in conjunction with another similar or identical engine. In this embodiment, the engine is a marine 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. However, in other implementations, engine 100 may be another type and / or size of engine. For example, the engine may be a stationary engine used to operate a generator in a power station. The total output of...

Abstract

Disclosed is a slurry fuel injector valve (200), comprising: a fuel outlet valve (220) through which slurry fuel is able to exit the slurry fuel injector valve towards a combustion chamber of an engine; a pump cavity (230); a pump element (231) that divides the pump cavity into a pump chamber (234) and an actuation chamber (236); a fuel conduit (212) through which slurry fuel is flowable from thepump chamber to the fuel outlet valve; and an actuation fluid conduit (240) through which actuation fluid is flowable from the actuation chamber to the fuel outlet valve.

Description

technical field [0001] The present invention relates to fuel injector valves for engines, such as two-stroke marine engines. In particular, the present invention relates to fuel injector valves for injecting non-Newtonian fuels, such as slurry or emulsion fuels. Background technique [0002] Current injection technology in diesel engines uses 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. Conventional diesel engines use pressure atomization of relatively low viscosity fuels with Newtonian characteristics. [0003] In order for the fuel to combust, it needs to be pumped at high pressure into a chamber within the fuel injector valve. Conventional fuel systems use high pressure pumps and common rail technology to deliver high pressure fuel, typically up to 1000 bar, to the fuel injector valves. In other engines, such as marine common rail four-stroke ...
