A method and system for monitoring any incursion of particulate matter from a gas hydrate formation into a well casing used for the production of the gas hydrate and determining the degree of incursion of particulate material within the distal end of the well casing.. .
|In-cylinder dynamic gas blending fuel injector and dual fuel engine|
A dual fuel engine utilizes a compression ignited pilot injection of liquid diesel fuel to ignite a mixture of gaseous fuel and air in each engine cylinder. The gaseous fuel is injected at a relatively low pressure directly into the engine cylinder from a fuel injector.
|Method and apparatus for reducing emissions and/or reducing friction in an internal combustion engine|
A method and apparatus for reducing at least one of hc, co, and nox emissions from an operating internal combustion engine fueled by hydrocarbon or similar fuels, such as alcohols, wherein a portion of the internal combustion chamber has aluminum and/or titanium containing surfaces coated with a titanium dioxide coating further comprising a dopant in and/or on the adherent titanium dioxide coating.. .
|Assembly and method for reducing nitrogen oxides, carbon monoxide and hydrocarbons in exhausts of internal combustion engines|
An assembly and method for reducing nitrogen oxides, carbon monoxide and hydrocarbons in exhausts of internal combustion engines, wherein the exhaust is acted upon in a first stage catalytic converter. A first portion of the first stage catalytic converter output is cooled and a second portion of the catalytic converter output is not cooled.
|Gasifier configured to electrodynamically agitate charged chemical species in a reaction region and related methods|
Embodiments are directed to a gasifier that electrodynamically agitates charged chemical species in a reaction region of a reaction vessel of a gasifier and related methods. In an embodiment, a gasifier includes a reaction vessel configured to gasify at least one hydrocarbon-containing feed material to synthesis gas.
|Gasifier having at least one charge transfer electrode and methods of use thereof|
Gasifiers that may be used for gasifying hydrocarbon-containing materials are disclosed. Methods for use of such gasifiers are also disclosed.
