Aimed at load-carrying mechanism, systematic study was made on the functions of basic topological structures and some functional structures of the cylinder head, such as sprayer jacket, ports, strengthen rib, jobbing sheet, etc., in the load carrying system. Moreover, the deformation characters of these structures in the processes of carrying and transmitting loads were also thoroughly studied by the thesis.

针对气缸盖承载机理，系统地研究了气缸盖中的基本拓扑结构和气缸盖中一些功能结构——喷油器护套、气道、气门导管座孔、中隔板和加强筋等结构在气缸盖承力体系中的作用，以及这些结构在承受和传递载荷过程中的变形特性。

However, because of the consuming time and result jumpiness of using CFD, CFD can't replace the steady flow test in process of the development of the engine intake port presently.

但由于CFD相对试验来说耗时长，而且各气门升程下计算数据波动较大，故目前开发优化气道流程中CFD仍不能完全替代气道稳流试验。

This explains why the new model is equipped with the powerful 1.9 JTD 16v Multijet developing 110 kW (150 bhp) plus a 6 speed manual gearbox with sports ratios.

这解释了为什么新的模式是与强大的1.9装备离散度16气门多点喷射开发110千瓦（150马力），加上6速手动变速箱体育比率。

The interior also features a fashion fabric known as Centorighe while the engine range includes a 77 bhp 1.4 8v unit and a 75 bhp 1.3 Multijet 16v unit, both category leaders for their power/fuel consumption ratio.

内饰还具有时装面料的Centorighe称为而引擎系列包括了77马力，1.4 8V的单位和1 75马力1.3多点喷射16气门的单位，都为他们的权力类别领导人/燃油消耗率。

Powered by the sparkling 70 bhp 1.3 16v Multijet turbodiesel engine, the Lancia Ypsilon MomoDesign has the same dimensions and architecture as the other versions in the range, but includes a number of aesthetic and chromatic features peculiar to this version, starting with the special 'Orange' paintwork (the colour of some of the luminous inserts that decorate the stand).

本站由波光粼粼的70马力13气门多点喷射涡轮增压柴油发动机，蓝旗亚地老虎MomoDesign具有相同的尺寸和该区域中的其他版本的架构，而是包括了美学和色彩所特有的功能，此版本与特殊的'橙色开始，数'漆（其颜色的发光插入的一些装饰的立场）。

At the launch the model will be offered with a choice between a petrol engine (1.4 8v, 77 bhp) and a turbodiesel (1.3 Multijet 16v, 90 bhp with a variable geometry turbo), both combined with five-speed mechanical transmissions; the 120 bhp 1.4 16v Turbo from the new T-Jet family will be available at a later date.

在该模型将与汽油发动机之间（1.4 8V的选择，提供了发射77马力）和一个涡轮增压柴油发动机（1.3多点喷射16气门，90可变几何涡轮增压马力），同时结合五速机械传动； 120马力涡轮增压1.4升16v从全新的T -喷气系列将在日后公布。

In order to satisfy combined simulation and optimization for the engine, the multi-objective and multi parameter nonlinear restriction programming was performed using the Matlab code that transfered the import parameters such as the structural, injection, valve timing, combustion timing and other parameters to the simulation model.

用Matlab编制了多目标、多参数非线性约束优化算法程序，通过调用仿真计算模型，改变输入参数如压缩比、空燃比、点火提前角和气门正时等的输入数值，实现了联合仿真优化。

Four-valve, pent roof cylinder head design uses two spark plugs per cylinder for efficient combustion and great power delivery at all rpms.

四气门，压抑屋顶缸盖设计采用两个火花塞每个气缸的燃烧效率和巨大的功率输出在所有从RPMS 。

Displacing 1854cc (113 cubic inches), the 48 degree V-twin air-cooled OHV 4-stroke engine benefits from a highly advanced specification that includes 4-valve twin-spark plug cylinder heads, forged pistons, pent roof combustion chambers, EXUP, oil cooling, fuel injection, 100mm diameter plated cylinders and a hydraulic clutch.

驱1854cc， 48度V型双风冷式ohv四冲程发动机的好处从一个高度发达的规格，其中包括4气门，双火花塞缸盖，伪造活塞，压抑的屋顶燃烧室， exup ，油冷却，燃油喷射， 100毫米直径的镀缸和液压离合器。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
