Abstract: An internal combustion engine for neutron diffraction analysis is provided. The engine includes an elongated piston chamber formed from an aluminum alloy to ensure maximum neutron visibility into the combustion chamber. An elongated piston assembly reciprocates within the elongated piston chamber, the piston assembly including an upper piston joined to a lower piston. The upper piston and the lower piston are hollow, thereby reducing the reciprocating mass and increasing neutron access to the combustion chamber. The upper piston is lubricated with a neutron-transparent fluorocarbon lubricant such as perfluoropolyether (PFPE), while the lower piston and the crankcase are lubricated with hydrocarbon lubricant. The engine enables 3D and time-resolved measurements of strain, stress, and temperature, as well as phase transformation, texture, and microstructure.

Abstract: An oil-spray tube assembly includes a tube having an outer circumferential surface, an inner circumferential surface defining a hollow center, a closed distal end, an open proximal end defining an axially recessed annular seat, and an orifice extending between the inner and outer surfaces. A poppet valve has a radially extending flange and is received in the hollow center with the flange disposed on the annular seat. The valve defines an inlet, a cylindrical valve chamber in fluid communication with the inlet, an outlet exiting the valve chamber, and a valve seat between the inlet and the outlet. A ball is disposed within the valve chamber and is movable between a closed position in which the ball is seated on the valve seat to sever fluid communication between the inlet and the outlet and an open position in which the ball is spaced from the valve seat to place the inlet and outlet in fluid communication.

Abstract: An oil pressure switch, which is connected in an oil path of a piston oil cooling jet to diagnose oil pressure, includes an upper body and a lower body, in which a plunger vertically moves according to oil pressure; a fixing plate that is disposed between the upper body and the lower body; a moving plate that selectively contacts a fixing plate according to movement of the plunger; a spring that generates an elastic force in a direction in which the moving plate selectively contacts the fixing plate; an output terminal that outputs an output signal according to contact between the moving plate and the fixing plate; and a parallel resistor that is electrically connected with the output terminal and electrically connected with a control resistor of a controller.

Abstract: A piston cooling jet includes a first body and a second body. The first body includes a housing having an inlet fluidly coupled with nozzle outlets. The second body is coupled to the first body to form an interior chamber disposed inside the first body and the second body. The interior chamber is fluidly coupled with the inlet and the nozzle outlets. The interior chamber directs fluid received via the inlet through the nozzle outlets and out of the piston cooling jet assembly in a direction towards a spray target.

Abstract: A galleryless piston having a reduced weight and a reduced operating temperature is provided. The piston includes an undercrown surface exposed from an underside of the piston, a ring belt, pin bosses each presenting a pin bore, and skirt panels depending from the ring belt and coupled to the pin bosses by strut. The piston further includes an inner undercrown region extending along the undercrown surface and surrounded by the skirt panels, the struts, and the pin bosses. The piston also includes outer pockets each extending along the undercrown surface and each surrounded by a portion of the ring belt, one of the pin bosses, and the struts coupling the one pin boss to the skirt panels. Cutouts are located in the pin bosses above the pin bores to increase the area of the undercrown surface and thus allow cooling oil to remove more heat from the undercrown surface.
