摘　　要：介绍了在S195柴油机基础上开发的新型内摆线单缸柴油机S195HC的机构原理和特点,分析了S195HC新型柴油机的活塞运动规律及其所带来的影响,研究了S195HC新型柴油机的配气特性.结果表明:与传统曲柄连杆机构相比,S195HC柴油机的活塞在上止点附近停留的时间比较长,活塞更接近上止点,有利于燃料的充分燃烧,改善内燃机的经济性;S195HC柴油机不存在二阶及更高阶往复惯性力,改善了内燃机的机械振动和噪声;S195HC柴油机的活塞运动特性有利于新鲜充量的进入,改善了燃烧过程.Based on S195 diesel engine,utilizing the hypocycloid principle,the new type hypocycloid single cylinder diesel engine,S195HC,was developed and its mechanism principle and characteristics are introduced.The motional law of piston and its influences in the new type S195HC diesel engine was analyzed.The valve characteristic of the new type S195HC diesel engine was studied.The results show that compared with traditional mechanism of crank and connection rod,the piston of S195HC diesel engine has longer residen...
