    摘要:

    采用往复振动机模拟小型二冲程发动机运转工况,实验研究汽油和甲醇为燃料时发动机气缸和活塞环间的摩擦特性,并比较分别使用润滑油新油、润滑油老化油、润滑油新油和老化油的混合油作为润滑油时气缸和活塞环间的摩擦特性。结果表明,以甲醇为燃料时的摩擦因数和磨损量均小于以汽油为燃料时的摩擦因数和磨损量,特别是使用添加了润滑油新油的燃料时的摩擦因数和磨损量最小。通过黏度和热重(TG)分析,探讨甲醇燃料改善气缸和活塞环间的摩擦特性的原因,结果表明,甲醇燃料具有较高的黏度和较低的摩擦因数,因而以甲醇为燃料时可以降低磨损

    Abstract:

    A sliding equipment was used to simulate the running condition of a small two-stroke engine,and the tribological properties between cylinder and ring of engine fueled by gasoline and methanol were studied.The tribological properties between cylinder and ring were compared when the new lubricant oil,the aging lubricant oil,and the mixture of the new lubricant oil and the aged oil were used as the lubricating oils respectively.Results show that the friction coefficient and wear volume of the engine fueled by methanol are smaller than that by gasoline,especially,the friction coefficient and wear volume of the engine with fuel adding new lubricant oil are the smallest.Based on the analysis of viscosity and thermogravimetry (TG),the reason why methanol fuel can improve the friction between cylinder and piston ring was discussed.It is found that methanol fuel has high viscosity and low friction coefficient,so the wear can be reduced when methanol is used as fuel.
