毕业设计(论文)中文摘要
近几年来,随着我国经济的持续发展,汽车的需求量继续保持高速的增长。并随着电子技术的发展,越来越多的汽车上采用了电子控制的发动机。
发动机是汽车的心脏,为汽车的行走提供动力,汽车的动力性、经济性、环保性。简单讲发动机就是一个能量转换机构,即将汽油(柴油)或天然气的热能,通过在密封汽缸内燃烧气体膨胀时,推动活塞作功,转变为机械能,这是发动机最基本原理。
,从它的构造结构、工作原理、以及对其故障点的分析和排除等方面,结合实际情况,分析数据,了解此类发动机加速不良故障的发生、检测、解除的过程。
关键词: 故障发动机检测排除

Title:Buick JunWei engine speed bad fault diagnosis and ruled out
Abstract:
In recent years, as the economy continues to develop, auto demand continues to maintain high-speed growth. And with the development of electronic technology, more and more cars used electronic control of the engine.
The engine is the heart of cars for car walk, powered car power, economy, environment protection. Simple speak engine is an energy conversion institutions, ing gasoline (diesel) or gas heat, through burns gas cylinder in seal in pushing a piston expands, energy, into mechanical energy, which is the most basic principle. Engine
This thesis is to JunWei buick V6 engine as test L/design object, from its tectonic structure, working principle, and the breakdown analysis and elimination of, connecting with the practice, analysis of data, understand such engine speed bad of failure, testing, termination process.
Keywords :Fault engine detection ruled out
