摘要： A steel piston with an oil gallery, and process for forming a steel piston oil gallery channel, which corresponds to the complex shape of the combustion bowl in the piston crown. The piston crown is made by a cast metal or powder metal forming process. The oil gallery channel is formed to the basic shape that corresponds to the shape of the walls of the combustion bowl. Machine-turning surfaces in the oil gallery channel can be machine-finished as desired. Surfaces in the oil gallery which cannot be machined with conventional turning operations, such as recesses and protrusions into the channel, are left in the original as-formed condition.

摘要： A piston and method of construction thereof is provided. The piston has a lower member with diametrically opposite skirt portions and axially aligned pin bores and an upper member joined to the lower member. The upper member has a substantially planar upper combustion surface and a combustion bowl depending from the upper combustion surface. An undercrown surface is formed directly opposite the combustion bowl and a combustion bowl rim transitions the combustion bowl with the upper combustion surface. At least one of the combustion bowl, the undercrown surface and the upper combustion surface has a machined surface and an “as forged” surface.

摘要： A steel piston with an oil gallery, and process for forming a steel piston oil gallery channel, which corresponds to the complex shape of the combustion bowl in the piston crown. The oil gallery channel is first forged to the basic shape that corresponds to the shape of the walls of the combustion bowl. Machine-turning surfaces in the oil gallery channel can be machine-finished as desired. Surfaces in the oil gallery which cannot be machined with conventional turning operations, such as recesses and protrusions into the channel, are left in the original forged condition.

摘要： A piston for an internal combustion engine including a cooling gallery and a complex combustion surface is provided. The piston includes an upper crown member joined to a lower member, for example by hybrid induction welding. A complex combustion bowl is formed in the upper crown member by forging. The combustion bowl includes at least one protrusion, and typically a plurality of protrusions spaced from one another. After the forging step and before the joining step, portions of an undercrown surface located opposite the spaces between the protrusions are machined, and portions located directly opposite the protrusions are left as-forged. The crown member is joined to the lower member, for example by hybrid induction welding.

摘要： A piston for a high temperature internal combustion engine is provided. The piston includes an upper wall, base wall, outer rib, and inner rib defining a cooling chamber therebetween, and a plurality of ring grooves formed in the outer rib. Only the second ring groove is formed with the keystone cross-section, and all of the other ring grooves are formed with the conventional rectangular cross-section. Thus, the piston can be formed with low manufacturing costs and can also provide exceptional performance when used in high temperature combustion engines, wherein the temperature at the first ring groove is greater than 280° C., and thus prevents carbon from depositing or burns off any carbon deposits, but the temperature at the second ring groove is between 200° C. and 280° C., in which case carbon deposits can form and cause the piston ring to stick.
摘要翻译：提供了一种用于高温内燃机的活塞。活塞包括在其间限定冷却室的上壁，底壁，外肋和内肋，以及形成在外肋中的多个环槽。只有第二环槽形成有梯形截面，并且所有其它环形槽都以常规的矩形横截面形成。因此，可以以低制造成本形成活塞，并且当在高温内燃机中使用时也可以提供出色的性能，其中第一环槽处的温度大于280℃，因此防止碳沉积或燃烧任何碳沉积物，但是第二环槽的温度在200℃和280℃之间，在这种情况下，碳沉积物可以形成并使活塞环粘结。
