Abstract: An apparatus and system for cooling the air charge of an internal combustion engine to increase power output while reducing engine emissions. The system utilizes gaseous fuel stored as a liquid wherein the liquefied gaseous fuel is vaporized and warmed at least partially with heat removed from the intake air charge supplied to the engine. In a preferred embodiment, the compressed intake combustion air is first cooled in an aftercooler against an ambiently cooled coolant and is subsequently cooled further by the chiller of the instant invention which utilizes the change in phase, between liquid and gas, of the alternative fuel to cool the incoming air charge. The fuel, in the gaseous phase, is then supplied to the engine in a controlled manner for combustion by the engine. The operation of this system is measured and controlled by a control box mounted in the engine compartment.

Inventor: GU GUOXING
IPC: F22B1/18
Filed: 2010-05-27
Abstract: A method for thermal recovery of heavy oil, bitumen and natural gas from a formation containing various hydrocarbons and an apparatus for generating a mixture of steam and flue gas, named as steamflue gas. In general, the method incorporates high temperature flue gas into a steam assisted gravity drainage (SAGD) operation to become a steamflue gas injection.  A mixture of high temperature flue gas and steam is injected into the SAGD top well within a formation to enhance recovery of heavy oil and bitumen. The high temperature flue gas is produced from the first burner burning inexpensive fuels, such as coal, used oil, scraped tire, petroleum coke and sludge containing high oil content; and the steam is generated by mixing water with the high temperature flue gas or the steam generated using a steam generator conventionally used in a SAGD recovery operation. The returning flue gas with entrained hydrocarbons from the formation is burned in the second burner as an additional fuel to preheat water or generate steam. Then the flue gas produced from the second burner is injected into the formation and acts to re-pressurize the formation which otherwise becomes depressurized when depleted of natural gas. Accordingly, environmental and economic advantages are realized with the methodology.

Abstract: A system and method are described that provide an alternative way in which to produce a Montgomery reduction from below by storing a new precomputed value used to substantially replace the µ and n values used in Montgomery reduction with a single value. By modifying the Montgomery reduction mechanism in this way, the number of multiplications and registers required to effect the Montgomery reduction can be reduced. To avoid having to store both µ and n, a modified reduction value or a logical shift or signed version of such a value can be used in place of µ and n for the bulk of the low-order reduction.
