Abstract: In a reciprocating engine piston, added equipment to renew the piston pin's oil film once per crankshaft rotation. The equipment is located between the connecting rod's small end and the underside of the piston crown. There is a plunger carrier with a plunger, and a saddle with a plunger bore. The saddle closely straddles the plunger carrier, maintaining the alignment of the arcuate plunger with the arcuate plunger bore, for a plunger stroke without friction. The small end's natural oscillation during crankshaft rotation powers the plunger's working cycle. There is an oil-filling stroke and a delivery stroke. The delivery is to the saddle's top, which is just below the piston crown. The oil pressure pushes upward on the piston crown, lifting the piston slightly and the piston pin bosses off the piston pin. In the small gap thus created, new oil can enter, recreating the oil film.

Abstract: The invention concerns a Wells turbine, comprising a hub with a plurality of rotor blades having a drop-shaped profile orienting from a profile nose; the rotor blades are attached to the hub in a rotary fashion by means of a foot part such that the rotor blade angle is variable with respect to the plane of rotation, wherein the associated rotational axis intersects the chord for each profile section in a threading point, which is located in a region between the profile nose and the aerodynamic center of the profile; the adjustment of the blade angle is made passively by the equilibrium occurring during the operation of the wells turbine between the aerodynamic torque, acting on the rotor blades, and the centrifugal torque, wherein the average density of the rotor blade is selected to be less than 2700 kg/m3 and/or the mass distribution within the profile is selected such that the surface centrifugal torque of the rotor blade is reduced relative to a profile made from a solid and/or the surface centrifugal torque of the rotor blades is at least partially balanced by compensatory weights, disposed at a distance from the rotational axis and perpendicular to the chord.

Abstract: A cylinder liner for an engine block assembly of an internal combustion engine is provided. The cylinder liner includes a liner member formed of cast iron and presenting an outer surface. A first portion of the outer surface of the liner member is machined to a reduced outside diameter. An aluminum-based material is then thermally sprayed onto the machined first portion, while a second portion of the outer surface remains uncoated. The coated cylinder liner is then placed in a mold, and another aluminum-based material is cast around the coated cylinder liner to form the engine block assembly. During the casting process, the two aluminum-based materials form a strong intermetallic bond between the liner member and the engine block.
