缸孔作为发动机完成燃料压缩、燃烧及爆发做功的能量转换室,与活塞形成发动机的最为重要的摩擦副,承受着各种载荷和温度的剧变,因此缸孔加工工艺的选择将直接影响到发动机的功率输出、机油消耗、尾气排放及发动机的可靠性,目前国内普遍采用平台网纹珩磨加工技术,而随着国家法律法规对排放要求的进一步的提高,特别是后续欧五、欧六的要求,对发动机缸孔的设计精度和加工质量提出了更高的要求,在平台网纹珩磨加工技术增加锥度珩磨是能够保证上述要求的有效手段之一。
Cylinder hole as the engine to complete the fuel compression, combustion and explosion work done energy conversion chamber, and piston form the most important friction pair of the engine, subject to a variety of load and temperature drastic changes, so the choice of cylinder machining process will directly affect the engine Of the power output, oil consumption, exhaust emissions and engine reliability, the current domestic widespread use of network technology hieroglyphics, and with the national laws and regulations to further improve the emission requirements, especially the follow-up requirements of the EU five, the European six , The engine cylinder bore design precision and processing quality put forward higher requirements in the platform hieroglyphing technology to increase taper honing is able to ensure that one of the effective means of the above requirements.
