The research work of this thesis has much guiding significance on the design of the two-stroke engine.

结论和提出气缸气口的改进设计方案。本文的工作对二冲程柴油机的结构设计具有一定的指导意义。

According to the request of construction features, processing spot, size precision, surface roughness and productivity that diesel engine air cylinder, sets the machine tool for single location horizontal type modular machine tool. Considered to the factor of the size precision, surface roughness, scrap removes and productivity and so on of the work piece, selects the Hard alloy not grind type surface milling cutter.

根据柴油机气缸体的结构特点、加工部位、尺寸精度、表面粗糙度及生产率等要求，确定该机床为单工位卧式组合机床；考虑工件尺寸精度，表面粗糙度，切屑的排除及生产率等因素，选用硬质合金不重磨式面铣刀；根据工件的尺寸、特点及其材料选择切削用量；然后，再经过切削用量来确定组合机床的通用部件；最后进行组合机床的总体设计。

The new UCS study uses detailed modeling to examine for the first time how diesel and gasoline vehicles compete among a variety of cars and trucks, applying improved engines and other conventional fuel-saving technologies that could be implemented today, as well as advanced and hybrid technologies that could be implemented within the next 10 to 15 years.

新的UCS研究报告采用详细建模的方法，第一次检测出了柴油机和汽油发动机在不同型号的汽车上竞争的结果。他们使用了改良后的引擎和传统的节油技术，这些技术今天就能应用，除此以外，还使用了高级的混合节油技术，这些高级技术也许在10到15年以后才能广泛应用在汽车上。

The effects of dimethyl carbonate as an oxygenate additive in diesel f uel on fuel characteristics,engine performances and emissions are studied.

By using contour plot method with Matlab s high performance on data processing and 3D graphics drawing to draw the universal characteristic curve of the GM-L65 diesel,provide a powerful backing for the integrated powertrain control and shift schedule s design.

根据总功率试验数据，采用曲面拟合的方法，利用MATLAB软件的数据处理和三维曲面功能，求出了GM-L65柴油机的万有特性，为动力传动系统的一体化控制以及换挡规律设计提供了依据。

Precise describe of geometry structure is an important premise to realize numerical simulation, but the diesel model refers to intake system, exhaust system, turbocharger system, fuel injection set, cylinder and crank case etc, which have complex structure, therefore, if the geometry model is established as true structure, it will spend a great lot of time and it is unrealizable and unnecessary.

几何结构的精确描述是实现准确实现数值模拟的重要前提，但柴油机模型涉及到进气系统、排气系统、涡轮增压系统、喷油组件、气缸和曲轴箱等诸多实体，而且结构极其复杂，如按真实实体结构建立计算几何模型需要花费大量时间且难以实现，也没有必要。
