摘要: 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.

摘要: A split-cycle internal combustion engine includes a variable displacement compressor having two or more cylinders, an adjustment mechanism for varying the displacement volume of the compressor and possibly the phase between the compressor and the motor, and a rotary motor having two or more expansion chambers. A passage valve system located between the compressor and the motor transfers working fluid and combustion exhaust products, and, in addition, mechanically and thermally isolates the compressor from the high pressures and temperatures present in the motor.

摘要: A method of making a piston for an opposed-piston engine comprises providing a piston. The piston comprises a substantially cylindrical portion including a sidewall and a piston crown located at an end of the piston. The piston crown comprises an end surface structured to form a combustion chamber when disposed within a cylinder bore in cooperation with an end surface of a cooperating opposing piston. A bonding layer including a bonding material is deposited on the end surface of the piston crown using a high velocity oxy-fuel spray process. At least one thermal barrier layer comprising ceramic material is deposited above the bonding layer.

摘要: In one configuration, the present disclosure provides a cylinder including a first housing, a second housing, and an insert. The first housing includes a first body portion and a first collar portion. The first body portion has a first inner diameter, and the first collar portion has a second inner diameter that is greater than the first inner diameter. The second housing includes a second body portion and a second collar portion. The second body portion has a third inner diameter and the second collar portion has a fourth inner diameter that is greater than the third inner diameter. The second housing is coupled to the first housing such that the first and second collared portions cooperate to form an annular channel. The insert is disposed within the annular channel formed by the first and second collared portions.

摘要: A linear compressor is provided that may include a shell provided with a refrigerant inlet; a cylinder provided inside of the shell to form a compression space; a piston that reciprocates inside of the cylinder to compress a refrigerant in the compression space; and a motor assembly that provides a drive force to the piston and provided with a permanent magnet. The piston may include a piston body having a cylindrical outer circumferential surface and a surface-treated area, which may be processed with a material having a predetermined hardness value, and a valve support provided at an end of the piston body and having a suctioning hole be in communication with the compression space. The valve support may form a first non-surface-treated area, which is not surface-treated.

摘要: A control apparatus of an engine including a cylinder into which a piston is reciprocatably fitted is provided. The apparatus includes a fuel injector, a water injector, and a controller. The controller includes an engine load determining module for receiving a parameter and determining whether an engine operating range is within a low high load range or a high load range. Within the low load range, the controller controls the fuel injector to inject fuel into a center region of a combustion chamber. Within the high load range, the controller controls the fuel injector to inject the fuel in a period between a latter half of compression stroke and an early half of expansion stroke, and the water injector to inject supercritical water or subcritical water toward a crown surface of the piston in a period that is after the injection and before a mixture gas ignition.
