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.

Abstract:: The mechanism principle and characteristics of the new cycloidal single-cylinder diesel engine S195HC developed on the basis of S195 diesel engine were introduced, the piston motion law and its influence of S195HC new diesel engine were analyzed, and the gas distribution characteristics of S195HC new diesel engine were studied. The results show that compared with the traditional crank connecting rod mechanism, the piston of S195HC diesel engine stays near top dead center for a long time, and the piston is closer to top dead center, which is conducive to full combustion of fuel and improves the economy of internal combustion engine. The S195HC diesel engine does not have second-order and higher-order reciprocating inertial forces, which improves the mechanical vibration and noise of the internal combustion engine; The piston movement characteristics of the S195HC diesel engine facilitate the entry of fresh charge and improve the combustion process.
