A piston of an internal combustion engine may include a piston head, a piston hub and a connecting rod having a joint end connected via an articulated connection to the piston hub. A reservoir may be provided and configured to receive splash oil for cooling the piston head. The reservoir may include at least one splash outlet directed towards the piston head. The reservoir may be arranged at the joint end of the connecting rod on a side facing towards the piston head.

Steering rod for connecting an actuator to a turbocharger drive member, comprising an elongated main body (2), which extends between a first end (5) equipped with a first through-hole (7), and a second end (6) equipped with a second through-hole (8), and two bushings (3), (4) immovably mounted in the through-holes (7), (8), wherein the bushings (3), (4) are made of a material which has a greater resistance to mechanical wear than the material delimiting the through-holes (7), (8), and wherein each bushing (3) (4) has an outer surface that is in contact with an inner part of the through-hole (7), (8) and has a radial recess (9), the second material tightening the bushing (3), (4) preventing it from rotating and filling the recess (9) preventing the bushing (3), (4) from being extracted from the second through-hole (7), (8).

The invention relates to a method for assembly, a method for disassembly and a connecting rod (1) for a combustion engine, the connecting rod (1) comprising a first and a second connecting rod part (2, 3), wherein the first connecting rod part (2) is configured to be connected to the second connecting rod part (3) when the connecting rod (1) is assembled around a rod-bearing journal of a crankshaft, wherein a connection between the first and the second connecting rod parts (2, 3) is an adhesive connection.

An engine has a connecting rod with a big end dimensioned such that a lower face height is a function of an upper face height, a face-to-face width, and a strap height and width. First and second bearing shells are received by the big end under a specified clamp load to form a convex axial profile in response to the big end dimensions, and a crankshaft crank pin interfaces with the convex axial profile. A method of assembling a connecting rod includes inserting upper and lower bearing shells into a big end having a lower face height as a function of an upper face height, a face-to-face width, and a strap height and width, where each shell has a free state with a straight axial profile and uniform cross-section, and fastening a cap at a specified load to form a convex axial profile of the upper and lower bearing shells.

An external combustion engine including a burner element, a heater head, a piston cylinder containing a piston, a cooler and a crankcase. The crankcase includes a crankshaft, a piston rod connected to the piston, a drive mechanism for converting the linear motion of the piston rod to rotary motion of the crankshaft and a linear cross-head bearing that is connected rigidly to the piston rod at one end and to the drive mechanism at the other end. Also the external combustion engine includes a piston clearance seal and a piston rod seal unit that has floating rod seals. The piston includes a inner dome to reduce axial heat transfer via radiation and convection.

A small end of a connecting rod includes an oil supply hole extending from an outer surface to an inner surface of the small end. The oil supply hole includes an oil storage groove and a communication hole. The oil storage groove is recessed from the outer surface and extends along the circumference of the small end. The communication hole extends through a bottom surface of the oil storage groove and connects the outer and inner surfaces. Opposite edges of the oil storage groove contact the outer surface in a direction the oil storage groove extends. The bottom surface of the oil storage groove has an opening contacting a wall surface of the communication hole. When the small end includes a distal end of the connecting rod defining a top, the opposite edges are located between the top and the opening in the bottom surface of the oil storage groove.
