Abstract: A rotary internal combustion engine with a rotor body made at least in major part of a first material, including at least one land protruding axially from each of its end faces and defining a contact surface extending at a fixed position with respect to the end faces. The contact surface frictionally engages a portion of the inner surface of the internal cavity of the engine, and at least the outer surface of the land includes a second material. The second material has a greater wear resistance than that of the first material with respect to frictional engagement with the portion of the inner surface of the internal cavity contacting the land. A method of axially positioning a rotor of a rotary engine within an internal cavity of an outer body of the engine are also discussed.

Abstract translation: 一种旋转式内燃机，其具有至少在第一材料的主要部分上制成的转子体，该旋转内燃机包括从其每个端面轴向突出的至少一个凸台，并限定了相对于端面在固定位置延伸的接触表面。 接触表面摩擦地接合发动机的内腔的内表面的一部分，并且至少外壳的外表面包括第二材料。 与第一材料的摩擦接合相比，第二材料具有比与内部空腔的内表面接触的部分更大的耐磨性。 还讨论了将旋转发动机的转子轴向定位在发动机的外部主体的内部空腔内的方法。

Abstract: A rotary internal combustion engine with a rotor body made at least in major part of a first material, with at least the contact surface of the rotor lands including a second material having a greater wear resistance than that of the first material with respect to frictional engagement with the portion of the inner surface of the internal cavity contacting the at least one land. For at least one of the end faces, the land(s) include(s) the first material and the contact surface is defined by a surface layer of the second material on the first material. A method of axially positioning a rotor of a rotary engine within an internal cavity of an outer body of the engine are also discussed.
