Abstract: Past pistons have been susceptible to reduced longevity due to increased forces of combustion thereon during operating cycles of an engine. The present two piece unitary piston increases the longevity of pistons used with increased forces of combustion. For example, a head member has a crown portion defining a ring band portion having a bottom surface and a support portion. And, a skirt member defines a ring band support surface and a top surface. The head member and the skirt member have a preestablished material strength being generally the same. The head member and the skirt member are joined by an inertia welding process. The force of combustion acting on the crown portion is resisted by the ring band support surface being in contacting relationship with the bottom surface. Thus, the skirt member structure supports and resists the bending moment of the combustion forces on the head member.

Abstract: A method for reducing the incidence of piston pin failure by providing a retainer assembly for piston pin plugs such that the plugs cannot be removed or shaken lose during operation. A plastic rod is inserted into the piston pin, and the rod is ultrasonically welded to the stems of mushroom-shaped plastic piston plugs such that the plugs cover the open ends of the pin and are held in place by the cooperation of structure between the plugs and the rod. In an alternate embodiment, the stem of each pin plug is hollow and a respective internally threaded brass insert is disposed in the stem and ultrasonically welded therein. An externally threaded rod is then engaged with the two internally threaded inserts to hold the plugs on the piston pin.

Abstract: Carbon deposits on engine components can negatively affect engine performance. An engine of the present disclosure includes at least one carbon deposit resistant engine component attached to an engine housing. The engine component includes at least one relatively high surface tension surface that is a non-contact wear surface and to which a relatively low surface tension coating is attached. The relatively low surface tension coating has a surface tension at least one of equal to and less than 30 dyne/cm.
