In the early days of cars, you actually had to crank the engine with a little handle. Now the crank ing motor or starter is just powerful enough to start the engine turning.

以前的汽车需使摇柄才能使发动机启动，现在启动机或点火机已足以使发动机启动了。

Using expurgation method divide combustion noise from mechanical noise, it showed combustion noise is main noise.

采用消去法分离了发动机的燃烧噪声和机械噪声，确定发动机燃烧噪声占主导地位。

This shows the extendible, flexible and reliable characters of the simulation system. Its can be used to study advanced technology aeroengine.

同时也说明该航空发动机性能仿真系统扩展性强、灵活可靠，可用于新型航空发动机的研究。

Based on the modular design theory, the module partition of extension clustering analysis methods and principles are applied to divide engine into different modules and make reasonable layout of engines product platform.

在模块化设计理论指导下，本文研究了可拓聚类分析的模块划分方法和划分原则，利用该理论，对发动机产品进行了模块划分，并对发动机的产品平台进行了合理的规划。

Fabre said he was looking to Asia for increased sales in the next 30 years, pointing that China only has around 600 helicopters but could see equal the 6000 or so helicopters operating in the United States in the next three decades. In 2009 60 of engines were to replace old engines, with 40 % new sales, Fabre believes that by 2039, 60 % of sales would be for new engines.

法布尔说，他希望亚洲在未来30年增加销售，指出中国目前只拥有大约600架直升机，但同样可以看到，在未来3年有6000多架直升机在美国工。2009 年，60%发动机销售是替换旧发动机，40％是新机销售，法布尔后认为，到2039年，销售额的60％将是新机销售。

法布尔说，他希望亚洲在未来30年增加销售，指出中国目前只拥有大约600架直升机，但同样可以看到，在未来3年有6000多架直升机在美国工。2009 年，60%发动机销售是替换旧发动机，40％是新机销售，法布尔后认为，到2039年，销售额的60％将是新机销售。

In order to improve the engine's power, emission and the economy of the fuel, we developed a system to investigate the electronic control fuel injection of motorcycle engine. Inspect each parameter real-timely and modify some parameters factitiously to get the best power performance, emission performance and economical performance.

0引言采用电子控制燃油喷射技术是减少机动车排放污染的最有效的方案，它具有反应快、实时性好、控制精度高与控制算法灵活等特点，可以根据发动机运行的不同工况，实现空燃比最佳控制，从而取得良好的排气净化和节油效果；而且相对于原来化油器式的燃油喷射方式来说，电子控制的进气压力损失小，燃油效率高，满足发动机动力性、经济性和排放性要求[1]。

1While launching machine Dai soon suddenly accelerate, if the transition spray bore to stop, especially the vacuum type carburetor appear a transition badly, hybrid once annoy sparse but clean a carburetor transition after turning off by oneself the bore then can smoothly start to launch machine behind, after start in response to steady mildly accelerate, as far as possible avoid nasty acceleration, the factitiousness result in transition bad.

当发动机怠速时突然加速，若过渡喷孔堵塞，特别是真空式化油器出现过渡性不良，混合气过稀而自行熄火后，清洗化油器过渡孔后便可顺利启动发动机，启动后应平稳柔和地加速，尽量避免急加速，人为造成过渡性不良。

The selection of fracture splitting forceparameter mainly depends on experience and no theory can abide by.In this paper aim at the technique of fracture splitting of engine connectingrod, the materials fitting to fracture splitting have been analysed, according tosome influence factors that the former has researched. The influence that thechemistry compositions to the mechanics function and the physical function insteel have been analyzed. The theory of quasistatic fracture splitting of suitableconnecting rod for engine EA827 has been studied. Aimed at the new materialC70S6, the quasistatic procedure has been numerical simulation analyzed bySPH non-mesh method. The solved stress intensity factor module andparameterize model building module have been developed based ANSYS byAPDL.

本论文主要研究发动机连杆裂解工艺，根据已知的一些连杆裂解影响因素，对适合裂解的连杆材料进行了综合分析，分析了钢中各组成化学成分对力学性能和物理性能的影响，针对新型裂解连杆材料C70S6钢，对捷达EA827发动机配套连杆进行了准静态裂解理论分析，并且利用SPH无网格方法对此进行了数值模拟分析，利用APDL开发了基于ANSYS的求解连杆裂解应力强度因子模块和参数化建模模块。

The power testing and misfire failure diagnosis are both the emphases of engine testing and diagnosis technology.

发动机功率检测与失火故障诊断均为发动机检测与诊断技术研究的重点。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
