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），又名壓燃式發動機，是內燃機的一種。其主要特徵為使用壓縮產生高壓及高溫點燃氣化燃料，而毋須另外提供點火。柴油引擎使用的原理稱為狄塞爾循環，為德國工程師魯道夫·狄塞爾（Rudolph Diesel）在1892年所發明。現時大部份的柴油引擎使用的燃料為柴油，但狄塞爾的發明原意是可以使用不同種類的燃料。事實上，他在1900年的世界博覽會上展示他的發明時，使用的燃料是花生油。

『貳』 柴油車dbf按鍵在哪

以柴油皮卡車為例如下圖圈出來的位置：

DPF是柴油微粒過濾器的縮寫。安裝在柴油車的排氣系統中，是一種過濾和減少排氣中顆粒物的裝置。它還有兩種再生系統技術，主動和被動。它的英文全稱是:(DieselParticulateFilter)。

它通過表面和內部混合過濾裝置捕獲顆粒，如擴散沉澱、慣性沉澱和線性攔截。DPF微粒過濾器可有效凈化廢氣中65%-90%的顆粒物，是凈化柴油車產生顆粒物最有效、最直接的方法之一，已在國際上實現商業化。

雖然這個pdf可以過濾大部分顆粒，但是它的收集器在工作的時候也涉及到再生的問題。有些朋友可能會問:什麼是再生？比如微粒會在濾清器內堆積，導致柴油機排氣背壓升高。

如果排氣背壓超過一定值，柴油機就會開始劣化，從而導致發動機功率和經濟性能下降。因此，必須及時清除沉積的顆粒，使過濾器恢復到原來的工作狀態，這就是上面提到的「再生」。

為了滿足我國日益嚴格的排放控制標准，柴油機排氣後處理技術作為整個柴油機排放控制系統的重要組成部分，正受到越來越多的關注。天津、北京、深圳相繼出台相關規定，國五標准柴油車必須配備DPF，才能上牌。

如今，日益嚴格的環保標准不僅是一個人的責任，也是我們所有人的責任。所以朋友們在買車的時候一定要注意車輛是否配備了DPF柴油濾清器，如果沒有，車管所是不會給它上牌的。

『叄』 柴油pdf是什麼

是指柴油dpf吧。
dpf指柴油車裝有的柴油微粒過濾器。
這個縮寫代表柴油顆粒過濾器，顧名思義，它的目的是阻止汽車尾氣排放出微小而有毒的顆粒物。但是，如果不遵守某些預防措施，許多DFP工作的方式會導致問題。
由於柴油發動機與汽油發動機不同地燃燒燃料，所以會產生大量煙塵作為燃燒過程的副產品。這種美好的，幾乎看不見的物質會在環境中造成重大的健康問題; DPF的工作是在可能發生之前將其摧毀並銷毀。DPF在2009年成為標准，但在此日期之前，一些柴油車型已經安裝了該技術。

『肆』 鄭州日產p2463故障碼

摘要 故障碼P2463是柴油機微粒過濾器（DPF）阻塞-灰燼積累的故障碼，適用於所有汽車製造商。柴油機微粒過濾器（DPF）的作用是除掉柴油機尾氣中的顆粒污染物和煙塵。柴油機微粒過濾器（DPF）一般分為可再生和不可再生兩種。可再生微粒過濾器一般通過高溫或利用氮氧化物氧化顆粒的方式來再生過濾器。排除故障之後還需要清除故障碼。清除代碼的時，嚴格按照特定車型所規定的故障代碼清除方法來進行，不能為了清除故障碼而直接拆除蓄電池的負極搭電線。

『陸』 汽車dpf再生是什麼意思

DPF是柴油顆粒過濾器，是安裝在柴油車排氣系統中，通過過濾來降低排氣中顆粒物的裝置。

柴油顆粒過濾器DPF通過表面和內部混合的過濾裝置捕捉顆粒，例如擴散沉澱、慣性沉澱或者線性攔截。

DPF是凈化柴油機顆粒物最有效、最直接的方法之一，可有效凈化廢氣中70％～90％的顆粒物。它已經在世界范圍內商業化了。

(6)柴油機pdf擴展閱讀：

微粒捕集器可以減少柴油發動機產生的煙塵90％以上。在車輛運行過程中，捕捉到的顆粒物會燃燒。

其基本工作原理是：如果柴油微粒過濾器塗層金屬鉑、銠、鈀、柴油機尾氣黑煙含有顆粒，通過特殊管道進入發動機排氣微粒陷阱，通過其內部緻密的袋式過濾器，炭煙粒子吸附在金屬纖維氈是由過濾器。

陷阱有主動再生和被動再生兩種方法。主動再生是指利用外部能量提高陷阱內的溫度，使顆粒著火燃燒。當捕集器內溫度達到550℃時，沉積的顆粒物會氧化燃燒；如果溫度不達到550℃，沉積物過多會堵塞疏水閥。
