汽车发动机自动熄火的故障诊断分析
【摘要】汽车是当代必不可少的一种交能工具,汽车的发动机是汽车的核心元件。随着社会的发展趋势汽车在全球的数量将越来越多,但现实的世界储存燃料已经越来越少,有科学家推算世界燃料只能用20年。那么20年后我们用什么来维持呢?没有了汽车这个交通工具世界经济将会是怎么样的一个现像,可想而知。那么我们就要研究出更能节省能源,也能适用新能源的汽车。只有这样才能让我们的经济保持并发展。
另一方面随着社会的发展经济的强大,汽车将要普及每家每户,中国的汽车产量已排名世界第三位就是最好的一个证明。那么我们需要人们懂得这些道理,假若发动机出现了问题也能自行解决。为我们提供为便,也能节省那么的时间和能源。在汽车技术日新月异的今天,电脑控制技术已经应用到车的各个系统,各种新结构、新技术的不断涌现,使汽车维修人员面临着更大的挑战。汽车维修已从以前的那种修理工最好当,怎么拆装怎么装的状况转变成一个技术含量高、难度大的工种。现代的修理技术的特征表现为“七分诊断,三分维修”。发动机的故障的具体方法是多种多样的,关键是如何出规律,积累经验,把感性认识上升到理性认识,再用理性认识指导维修实践。

The Typical Cars Engine Principle of New Technologies
汽车熄火
AbstractMotor vehicles is contemporary an indispensable to be tools, the Automobile Engine Motor core components. With the development trend cars in the world will be more and more, but the reality of the storage of fuel is shrinking, scientists estimated world fuel only 20 years. The 20 years, we used to maintain what? The car that transport the world economy will be how the situation, one can imagine. Then we must study more energy can apply the new energy vehicles. Only by so doing can we maintain the economic and development. On the other hand with social development of the economy is strong, and motor vehicles will be universal every household, China' s auto output has ranked the third place is the best proof. Then we need people to understand the reason, if the engine can be solved. For us as we can save the time and energy. In the automotive technological advances, computer control technology has been applied to the various systems, the new structure, the emerging new technologie
s, the vehicle maintenance personnel face greater challenges. Vehicles from the previous that repair work best when, how assembling How to install the situation into a high technological content and difficulty of workers. Modern technology in the repair characterized as "diagnostic and maintenance 3". engine failure of the specific method is diverse,the key is how to identify laws, and accumulate experience, and rose to rational consciousness perceptions and guidance for rational knowledge maintenance practice
