A diesel engine (also known as a compression-ignition engine and sometimes capitalized as Diesel engine) is an internal combustion engine that uses the heat of compression to initiate ignition to burn the fuel, which is injected into the combustion chamber ring the final stage of compression. This is in contrast to spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline), which uses a spark plug to ignite an air-fuel mixture. The diesel engine is modeled on the Diesel cycle. The engine and thermodynamic cycle were both developed by Rudolf Diesel in 1897.
The diesel engine has the highest thermal efficiency of any regular internal or external combustion engine e to its very high compression ratio. Low-speed diesel engines (as used in ships and other applications where overall engine weight is relatively unimportant) often have a thermal efficiency which exceeds 50 percent.
Diesel engines are manufactured in two stroke and four stroke versions. They were originally used as a more efficient replacement for stationary steam engines. Since the 1910s they have been used in submarines and ships. Use in locomotives, large trucks and electric generating plants followed later. In the 1930s, they slowly began to be used in a few automobiles. Since the 1970s, the use of diesel engines in larger on-road and off-road vehicles in the USA increased. As of 2007, about 50 percent of all new car sales in Europe are diesel.
The world's largest diesel engine is currently a Wärtsilä marine diesel of about 80 MW output.
Rudolf Diesel, of German nationality, was born in 1858 in Paris where his parents were German immigrants.[7] He was ecated at Munich Polytechnic. After graation he was employed as a refrigerator engineer, but his true love lay in engine design. Diesel designed many heat engines, including a solar-powered air engine. In 1892 he received patents in Germany, Switzerland, the United Kingdom and filed in the United States for "Method of and Appartus for Converting Heat into Work".[8] In 1893 he described a "slow-combustion engine" that first compressed air thereby raising its temperature above the igniting-point of the fuel, then graally introcing fuel while letting the mixture expand "against resistance sufficiently to prevent an essential increase of temperature and pressure", then cutting off fuel and "expanding without transfer of heat".[citation needed] In 1894 and 1895 he filed patents and addenda in various countries for his Diesel engine; the first patents were issued in Spain (No.16,654), France (No.243,531) and Belgium (No.113,139) in December 1894, and in Germany (No.86,633) in 1895 and the United States (No.608,845) in 1898.[9] He operated his first successful engine in 1897. His engine was the first to prove that fuel could be ignited without a spark.[citation needed]
Though best known for his invention of the pressure-ignited heat engine that bears his name, Rudolf Diesel was also a well-respected thermal engineer and a social theorist. Diesel's inventions have three points in common: they relate to heat transfer by natural physical processes or laws; they involve markedly creative mechanical design; and they were initially motivated by the inventor's concept of sociological needs. Rudolf Diesel originally conceived the diesel engine to enable independent craftsmen and artisans to compete with instry.[10]
At Augsburg, on August 10, 1893, Rudolf Diesel's prime model, a single 10-foot (3.0 m) iron cylinder with a flywheel at its base, ran on its own power for the first time. Diesel spent two more years making improvements and in 1896 demonstrated another model with a theoretical efficiency of 75 percent, in contrast to the 10 percent efficiency of the steam engine. By 1898, Diesel had become a millionaire. His engines were used to power pipelines, electric and water plants, automobiles and trucks, and marine craft. They were soon to be used in mines, oil fields, factories, and transoceanic shipping.
The diesel internal combustion engine differs from the gasoline powered Otto cycle by using highly compressed, hot air to ignite the fuel rather than using a spark plug (compression ignition rather than spark ignition).
In the true diesel engine, only air is initially introced into the combustion chamber. The air is then compressed with a compression ratio typically between 15:1 and 22:1 resulting in 40-bar (4.0 MPa; 580 psi) pressure compared to 8 to 14 bars (0.80 to 1.4 MPa) (about 200 psi) in the petrol engine. This high compression heats the air to 550 °C (1,022 °F). At about the top of the compression stroke, fuel is injected directly into the compressed air in the combustion chamber. This may be into a (typically toroidal) void in the top of the piston or a pre-chamber depending upon the design of the engine. The fuel injector ensures that the fuel is broken down into small droplets, and that the fuel is distributed evenly. The heat of the compressed air vaporizes fuel from the surface of the droplets. The vapour is then ignited by the heat from the compressed air in the combustion chamber, the droplets continue to vaporise from their surfaces and burn, getting smaller, until all the fuel in the droplets has been burnt. The start of vaporisation causes a delay period ring ignition, and the characteristic diesel knocking sound as the vapor reaches ignition temperature and causes an abrupt increase in pressure above the piston. The rapid expansion of combustion gases then drives the piston downward, supplying power to the crankshaft.[22] Engines for scale-model aeroplanes use a variant of the Diesel principle but premix fuel and air via a carburation system external to the combustion chambers.
As well as the high level of compression allowing combustion to take place without a separate ignition system, a high compression ratio greatly increases the engine's efficiency. Increasing the compression ratio in a spark-ignition engine where fuel and air are mixed before entry to the cylinder is limited by the need to prevent damaging pre-ignition. Since only air is compressed in a diesel engine, and fuel is not introced into the cylinder until shortly before top dead centre (TDC), premature detonation is not an issue and compression ratios are much higher.
柴油引擎（Diesel Engine），又名压燃式发动机，是内燃机的一种。其主要特征为使用压缩产生高压及高温点燃气化燃料，而毋须另外提供点火。柴油引擎使用的原理称为狄塞尔循环，为德国工程师鲁道夫·狄塞尔（Rudolph Diesel）在1892年所发明。现时大部份的柴油引擎使用的燃料为柴油，但狄塞尔的发明原意是可以使用不同种类的燃料。事实上，他在1900年的世界博览会上展示他的发明时，使用的燃料是花生油。

‘贰’ 柴油车dbf按键在哪

以柴油皮卡车为例如下图圈出来的位置：

DPF是柴油微粒过滤器的缩写。安装在柴油车的排气系统中，是一种过滤和减少排气中颗粒物的装置。它还有两种再生系统技术，主动和被动。它的英文全称是:(DieselParticulateFilter)。

它通过表面和内部混合过滤装置捕获颗粒，如扩散沉淀、惯性沉淀和线性拦截。DPF微粒过滤器可有效净化废气中65%-90%的颗粒物，是净化柴油车产生颗粒物最有效、最直接的方法之一，已在国际上实现商业化。

虽然这个pdf可以过滤大部分颗粒，但是它的收集器在工作的时候也涉及到再生的问题。有些朋友可能会问:什么是再生？比如微粒会在滤清器内堆积，导致柴油机排气背压升高。

如果排气背压超过一定值，柴油机就会开始劣化，从而导致发动机功率和经济性能下降。因此，必须及时清除沉积的颗粒，使过滤器恢复到原来的工作状态，这就是上面提到的“再生”。

为了满足我国日益严格的排放控制标准，柴油机排气后处理技术作为整个柴油机排放控制系统的重要组成部分，正受到越来越多的关注。天津、北京、深圳相继出台相关规定，国五标准柴油车必须配备DPF，才能上牌。

如今，日益严格的环保标准不仅是一个人的责任，也是我们所有人的责任。所以朋友们在买车的时候一定要注意车辆是否配备了DPF柴油滤清器，如果没有，车管所是不会给它上牌的。

‘叁’ 柴油pdf是什么

是指柴油dpf吧。
dpf指柴油车装有的柴油微粒过滤器。
这个缩写代表柴油颗粒过滤器，顾名思义，它的目的是阻止汽车尾气排放出微小而有毒的颗粒物。但是，如果不遵守某些预防措施，许多DFP工作的方式会导致问题。
由于柴油发动机与汽油发动机不同地燃烧燃料，所以会产生大量烟尘作为燃烧过程的副产品。这种美好的，几乎看不见的物质会在环境中造成重大的健康问题; DPF的工作是在可能发生之前将其摧毁并销毁。DPF在2009年成为标准，但在此日期之前，一些柴油车型已经安装了该技术。

‘肆’ 郑州日产p2463故障码

摘要 故障码P2463是柴油机微粒过滤器（DPF）阻塞-灰烬积累的故障码，适用于所有汽车制造商。柴油机微粒过滤器（DPF）的作用是除掉柴油机尾气中的颗粒污染物和烟尘。柴油机微粒过滤器（DPF）一般分为可再生和不可再生两种。可再生微粒过滤器一般通过高温或利用氮氧化物氧化颗粒的方式来再生过滤器。排除故障之后还需要清除故障码。清除代码的时，严格按照特定车型所规定的故障代码清除方法来进行，不能为了清除故障码而直接拆除蓄电池的负极搭电线。

‘陆’ 汽车dpf再生是什么意思

DPF是柴油颗粒过滤器，是安装在柴油车排气系统中，通过过滤来降低排气中颗粒物的装置。

柴油颗粒过滤器DPF通过表面和内部混合的过滤装置捕捉颗粒，例如扩散沉淀、惯性沉淀或者线性拦截。

DPF是净化柴油机颗粒物最有效、最直接的方法之一，可有效净化废气中70％～90％的颗粒物。它已经在世界范围内商业化了。

(6)柴油机pdf扩展阅读：

微粒捕集器可以减少柴油发动机产生的烟尘90％以上。在车辆运行过程中，捕捉到的颗粒物会燃烧。

其基本工作原理是：如果柴油微粒过滤器涂层金属铂、铑、钯、柴油机尾气黑烟含有颗粒，通过特殊管道进入发动机排气微粒陷阱，通过其内部致密的袋式过滤器，炭烟粒子吸附在金属纤维毡是由过滤器。

陷阱有主动再生和被动再生两种方法。主动再生是指利用外部能量提高陷阱内的温度，使颗粒着火燃烧。当捕集器内温度达到550℃时，沉积的颗粒物会氧化燃烧；如果温度不达到550℃，沉积物过多会堵塞疏水阀。
