A piston for a heavy duty diesel engine including a composite layer forming at least a portion of a combustion surface is provided. The composite layer has a thickness greater than 500 microns and includes a mixture of components typically used to form brake pads, such as a thermoset resin, an insulating component, strengthening fibers, and an impact toughening additive. According to one example, the thermoset resin is a phenolic resin, the insulating component is a ceramic, the strengthening fibers are graphite, and the impact toughening additive is an aramid pulp of fibrillated chopped synthetic fibers. The composite layer also has a thermal conductivity of 0.8 to 5 W/m·K. The body portion of the piston can include an undercut scroll thread to improve mechanical locking of the composite layer. The piston can also include a ceramic insert between the body portion and the composite layer.

An engine room structure for a vehicle uses dividing portions of plural wall members forming a cover member, and can thereby easily form a through portion through which plural routing members are caused to pass by notch-shaped portions without forming a substantial through hole. An engine room structure for a vehicle, which includes a cover member covering an upper portion of an engine and in which a through portion is formed in the cover member, and plural routing members pass through the through portion. The cover member is divided into at least a first member and a second member, continuous notch-shaped portions are formed along a partial dividing line between the first member and the second member in either one of those, and the through portion for the plural routing members is formed with the notch-shaped portions of the one member and an end portion of the other member.

A method for applying a thermal barrier coating (TBC) to a surface of a cast component includes providing a core, applying the TBC to the core to form a coated core, disposing the coated core within a casting mold, casting metal around at least a portion of the coated core to form a casting intermediary, and removing the core from the casting intermediary to form a cast component. The TBC includes hollow microspheres comprising metal, glass, and/or ceramic materials. The hollow microspheres can have an average diameter of about 10 μm to about 100 μm. The component can be an automotive component, such as an engine intake assembly, an engine exhaust manifold, an engine block, and/or an engine cylinder head. The surface of the cast component can be one or more surfaces which define an engine intake passage, an engine exhaust passage, and an engine combustion chamber.

A component for an engine is provided. The component includes a thermal barrier coating applied to a body portion formed of metal, such as steel or another ferrous or iron-based material. According to one embodiment, a bond layer of a metal is applied to the body portion, followed by a mixed layer of metal and ceramic with a gradient structure, and then optionally a top layer of metal. The thermal barrier coating can also include a ceramic layer between the mixed layer and top layer, or as the outermost layer. The ceramic includes at least one of ceria, ceria stabilized zirconia, yttria, yttria stabilized zirconia, calcia stabilized zirconia, magnesia stabilized zirconia, and zirconia stabilized by another oxide. The thermal barrier coating can be applied by thermal spray. The thermal barrier coating preferably has a thickness less than 200 microns and a surface roughness Ra of not greater than 3 microns.

A piston for an internal combustion engine includes a piston body. The piston body includes a head, two side walls, two skirts, and a reinforcement member. The head includes a recessed crown. Each side wall includes a pin boss configured to support a piston pin. The two skirts are respectively located at a thrust side with respect to an axis of the piston pin and an anti-thrust side with respect to the axis of the piston pin. The reinforcement member includes two legs and a connecting portion connecting upper ends of the two legs. The two legs are respectively insert-casted in the two skirts. The connecting portion is insert-casted in the head.

摘要:
A method and apparatus for the oxy-combustion of fuel in an internal combustion engine (ICE) used to power a vehicle converts the free energy available onboard the vehicle in the form of waste heat from the engine exhaust gas stream and coolant system into electrical and/or mechanical energy which energy is used to separate oxygen from air to eliminate or significantly reduce the volume of nitrogen entering the ICE's combustion chamber, and thereby reduce NOx pollutants released into the atmosphere and increase the concentration of CO2 in the engine exhaust stream for capture using an integrated system to compress and increase the density of the captured CO2 for temporary on-board storage until it is discharged at a recovery station, e.g., during vehicle refueling.
