Embodiment Construction

[0012] The present invention is generally directed to a socket suitable for positioning an engine component in an engine. The sleeve includes walls defining a channel. Engine components are positioned in the channels, and heat transfer devices are positioned within the walls.

[0013] figure 1 with figure 2 One embodiment of a sleeve 10 of the present invention is shown. Socket 10 may be used to locate engine components in an engine, and in particular, may be used to locate engine components in a cylinder head or cylinder block. For example, an engine component could be a fuel injector, a valve stem, a thermocouple, or a spark plug. Specifically, sleeve 10 may be a fuel injector sleeve for positioning a fuel injector in a cylinder head adjacent to an engine coolant passage such that the fuel injector tip protrudes into a combustion chamber of the engine. Alternatively, the sleeve 10 may be a valve guide for positioning the valve stem to position the cylinder head adjacen...

Abstract

The present invention is directed to an engine component sleeve with an integrated heat transfer device. The sleeve includes walls defining channels, and one or more heat transfer devices. Each heat transfer device includes at least one cavity enclosed within a wall and a working fluid located within the cavity.

Description

technical field [0001] The present invention is directed to an engine component sleeve with integrated heat transfer means. The sleeve includes walls and channels, and the heat transfer means is disposed within the walls. Background technique [0002] Internal combustion engines typically include a plurality of cylinders in a cylinder block sealed by a cylinder head, the cylinders having a piston located inside each cylinder. A combustion chamber is formed between the piston head, cylinder wall and cylinder head face. Other engine components, such as valves, fuel injectors, thermocouples, and spark plugs, may be mounted inside or on the cylinder head or block. [0003] To reduce emissions and improve efficiency, engine power density is increased by reducing engine size and weight while maintaining the same power output. However, in order to maintain a similar output to a larger engine, the relative pressure and temperature within the combustion chamber will increase. Cyl...
