oversquare engine

The composition and properties of two stroke engine oils with biodegradability were discussed;Points for attention were given on developing two stroke engine oils with high performances and low pollution to enviromental protection.

介绍了生物降解性试验方法ＣＥＣ－Ｌ－３３－Ｔ－８２法，对生物降解性的二冲程发动机油的组成与性能评定进行了讨论，并给出了研制对环境有益的高性能、低污染的二冲程发动机油应注意的问题，对我国生物降解性润滑剂的研制提出了建

The paper deals with the data base technology for visualized numerical calculation of flows in exhaust channels, transfer passages, ports and cylinder in two stroke engine.

讨论了二冲程发动机扫、排气道和气口气缸内气体流动数值计算可视化数据库技术，采用合理的数据结构及约束管理机制，提出了一种面向对象的数据库结构化模块设计方法。

"As lower hood lines and over square engines became popular, the semi-slipper and full-slipper pistons came into use. "

由于低发动机罩和短行程发动机的进一步普及,半围延裙活塞和滑裙式活塞开始使用。

"One reason for the slipper piston is that, on the short-stroke, over square engine, the piston skirt had to be cut away to make room for the counterweights on the crankshaft. "

使用滑裙活塞的原因是:短行程发动机需除去部分活塞裙部,从而为曲轴的平衡重让出空间。
