    摘要： A piston and cylinder assembly for an engine is disclosed. The assembly includes a piston including an aluminum alloy piston body having a crown and a skirt extending from the crown. The skirt has an exterior surface having a surface finish in a wave form with peaks and valleys, and having a roughness total between approximately 6 and 12 micrometers, the roughness total (Rt) being defined as the difference between the highest peak and lowest valley within an assessment length. The surface finish has an approximate peak-to-peak distance between 0.17 and 0.25 millimeters within the assessment length. The exterior surface is coated with a nickel ceramic composite coating. An aluminum alloy cylinder bore is disposed in an engine block and is configured to receive the piston body. The cylinder bore has a bore surface having a roughness average (Ra) between approximately 0.09 and 0.25 micrometers. The cylinder bore may be made of a eutectic Al—Si alloy including other alloying elements.

    摘要翻译： 公开了一种用于发动机的活塞和气缸组件。 该组件包括活塞，该活塞包括具有冠部的铝合金活塞体和从冠部延伸的裙部。 裙部具有外表面，其表面光洁度为波峰形，峰值和谷值，粗糙度约为6至12微米，粗糙度总数（Rt）定义为最高峰和最低谷之间的差值 评估长度。 表面光洁度在评估长度内具有0.17和0.25毫米之间的近似峰 - 峰距离。 外表面涂有镍陶瓷复合涂层。 铝合金气缸孔设置在发动机缸体中并构造成接收活塞体。 气缸孔具有在大约0.09和0.25微米之间的粗糙度平均值（Ra）的孔表面。 气缸孔可以由包括其它合金元素的共晶Al-Si合金制成。

    摘要： A piston assembly is provided for use in an engine. The piston assembly includes a piston body including a crown with a skirt extending from the crown. The skirt has an exterior surface. The exterior surface has a surface finish in a wave form with peaks and valleys, and having a roughness total between approximately 6 and 8 micrometers. The roughness total is defined as the difference between the highest peak and lowest valley within an assessment length. The surface finish has an approximate peak-to-peak distance between 0.18 and 0.23 mm within the assessment length. A composite coating is provided over the exterior surface.
