摘要： An apparatus includes first and second movable members for coupling force therebetween and a magnetic flux coupling element. Each of the first and second movable members has an array of magnetic poles. The first and second movable members are arranged concentrically for relative rotation therebetween. The magnetic flux coupling element is arranged between the first and second movable members, thereby providing a flux density region of relatively high magnetic flux density between a pole of the first movable member and a pole of the second movable member. The magnetic flux coupling element is split along an axis orthogonal to a direction of motion of the first and second movable members into a plurality of flux coupling parts.

摘要： A water jacket for a cylinder head of an internal combustion engine includes a coolant chamber arranged to permit the flow of coolant within the water jacket and a coolant conduit positioned to permit the flow of coolant proximate to a recess for receiving an exhaust valve mounted to the cylinder head. The coolant conduit is in fluid communication with the coolant chamber, and the coolant conduit is shaped as a complex curve. A water jacket includes a pair of apertures arranged to receive a spark plug and a fuel injector. The apertures are separated by a separating member, and a coolant chamber is arranged to permit the flow of coolant about the apertures. The separating member includes a coolant channel in fluid communication with the coolant chamber so as to permit the flow of coolant between the apertures.

摘要： A method of operating an internal combustion engine comprising a cylinder and a piston, the method including injecting into the cylinder, as a liquid, a fuel which has been condensed into its liquid phase via a refrigeration process, such that the fuel vaporises into its gaseous phase during a compression stroke of the piston and before combustion such that a rise in temperature caused by the compression stroke is limited by the absorption of heat by the fuel.

摘要： A process for removing hydrocarbons from a feed stream containing hydrocarbons includes introducing ozone to the feed stream to produce an ozone doped stream containing ozone and hydrocarbons, and contacting the ozone doped stream with a supported metal catalyst at a temperature of from 100° C. to 300° C. to produce a treated stream, wherein the supported metal catalyst comprises iron supported on a support selected from aluminosilicates, silica-aluminas, silicates and aluminas. A process for removing NOx from a feed stream containing NOx, and an apparatus for removing hydrocarbons and/or NOx from a feed stream containing hydrocarbons and/or NOx are also provided.
