一、前言对发动机提出的提高功率,降低燃料、润滑油消耗以节约运输费用,减少排气、嗓声公害以及提高使用寿命等要求,愈来愈紧迫。为了适应上述要求,发动机方面的解决措施直接涉及到活塞的设计问题,对活塞的结构和材质的多样化要求已成为活塞厂商的重大课题。本文以柴油机为主叙述往复式内燃机活塞 First, the foreword To the engine to raise the power, reduce fuel, lubricating oil consumption in order to save transportation costs, reduce emissions, voice pollution and improve life expectancy and other requirements, more and more urgent. In order to meet the above requirements, engine solutions directly related to the piston design issues, the piston structure and material requirements of the diversification has become a major issue for piston manufacturers. In this paper, the main piston reciprocating internal combustion engine narrative
