Dongfeng 1 1G diesel locomotive (DF 1 1G) is a double-engine reconnection quasi-high-speed diesel locomotive used in China Railway, which is manufactured by Qishuyan Locomotive and Rolling Stock Factory in China.
Brief introduction of Dongfeng 1 1G "crossover" diesel locomotive
Dongfeng 1 1G diesel locomotive is a quasi-high speed two-engine passenger diesel locomotive. Dongfeng 1 1G locomotive was specially developed for the fifth speed increase of China Railway. According to the task that Qishuyan Locomotive & Rolling Stock Factory was given by the Ministry of Railways in 2003 to develop speed-up locomotives for the fifth speed-up of China Railway, the diesel locomotive Dongfeng 1 1g was developed by Qishuyan Factory on the basis of Dongfeng 1 1G, and the model code was DF1g. In June of the same year165438+1October, the trial production of two prototypes was completed and mass production began. At that time, the Ministry of Railways was promoting the slogan of "leap-forward development of railways", so the word "leap" was marked on the body of each Dongfeng 1 1G locomotive. Dongfeng 1 1G locomotive adopts a fixed double-machine reconnection combination, which consists of two single-section locomotives with the same structure. A single locomotive adopts a single cab, and its running parts are the same as those of Dongfeng 1 1 locomotives. Equipped with 16V280ZJA diesel engine, the maximum working power is 2× 36 10KW. The total weight of the locomotive is 2× 138 tons, the nominal power of the locomotive is 2×3040 kW, the maximum speed is 170 km/h, the axle type is 2(Co-Co), and the axle weight is 23 tons. It has the function of locomotive supplying power to passenger cars. Each locomotive is equipped with an auxiliary generator, and two locomotives can supply power independently. Adopt streamlined head shape to reduce the pressure wave when meeting with adjacent cars, standardize bridge and pipeline, and adopt microcomputer network control technology. Its design fully draws lessons from the mature and reliable technologies of Dongfeng 1 1 and Dongfeng 1 1Z locomotives, and some key components are imported, using mature and reliable technologies from abroad. Dongfeng 1 1G was the most advanced AC DC diesel locomotive operated by China Railway at that time. Dongfeng 1 1G locomotive traction 18-20 bus can reach 160 km/h on a slope of three thousandths.
yield
As of February 2008, Dongfeng/KOOC-0//KOOC-0/58 diesel locomotives have been manufactured/KOOC-0//KOOC-0/58 sets (79 groups), with the largest locomotive number of 065438. The first batch of DF 1 1G locomotives were distributed to Beijing section of Beijing Railway Bureau and Shanghai section of Shanghai Railway Bureau on April 8, 2004, and long-distance operation was implemented. DF 1 1G locomotive, as one of the main models for the fifth speed increase, is mainly used to draw express passenger trains on Beijing-Shanghai lines and other lines. At that time, the Ministry of Railways operated Dongfeng 1 1G locomotive-drawn through express train 1 1 pair. On April 8th, 2007, China Railway increased its speed for the sixth time, and the 2300km direct train from Beijing to Fuzhou with Dongfeng 1 1G locomotive set a new record for the longest running interval. In 2008, the through express passenger train on the Beijing-Shanghai line was replaced by the EMU train, and the Dongfeng 1 1G locomotive and the traction through express train body were handed over to other lines for use.

technical characteristics
The 16V280ZJA diesel engine was installed by double-engine reconnection, and the turbocharger imported from Swiss ABB company was adopted. The loading power of diesel engine is 2×36 10 kW, which greatly improves the traction power. JF204D three-phase AC synchronous generator produced by Yongji Electric Machine Factory is adopted, and six ZD 106E four-pole series-excited DC traction motors are operated in parallel. There is still a residual acceleration of 0.0245 m/s2 when the speed of 20 buses is 160 km/h; And the reliability of the locomotive is improved. The locomotive adopts first-class resistance braking, and the locomotive braking system adopts electro-pneumatic braking. It has the function of supplying power to the train (machine supply). The locomotive is equipped with auxiliary diesel engine and generator. The diesel engine powered by Germany MTU Company is adopted, and the maximum power supply is 2×400 kW. There are two different power supply systems for buses, the first is AC 380V power supply system, and the improved design of DC 600V power supply system was completed in February 2004. 29 pairs of locomotives numbered 000 1 to 0066 (except 004 1/0042, 0047/0048 and 0053-0056) use AC power supply, while the numbers are 004 1/0042 and 0047/0046.

Technical improvement
Locomotive sign
Dongfeng 1 1G locomotive is basically based on Dongfeng 1 1, which has the functions of locomotive power supply system and double-machine reconnection. It took only one and a half months from the finalization of the project to the painting of the whole vehicle. All the staff of Qi Factory worked overtime and worked hard to complete one ship after another in the history of locomotive design and manufacturing in China. At the same time, due to the mature design of DF 1 1 for most parts, the maturity of the locomotive is improved. So this car doesn't use DF8CJ's 16V280ZJB diesel engine and adopt AC drive, and the top speed can run to 200km/h, as most fans say.
The front of the vehicle
Although the interface in the reconnection area inherits many things from DF 1 1 locomotive, DF 1 1G still has some remarkable improvements. The most obvious thing is the appearance of the locomotive. In terms of appearance design, the car abandoned the old-fashioned design of DF 1 1, boldly adopted a streamlined head shape, and adopted the already designed forming drawings of DF1/AJ. Moreover, imported high-grade bright paint (similar to car paint) is also used in the exterior paint of locomotives. In addition to the appearance of the locomotive, the internal design of DF 1 1G is also different from DF 1 1. First of all, the car is controlled by microcomputer, and some operations that used to need to enter the engine room are changed to computer operation, and some buttons in the engine room are also changed to driver's desk operation. If the locomotive breaks down during operation, the driver can remove the fault by touching the touch screen of the computer. For example, in operation, if the traction motor of a locomotive fails, the driver can cut off the traction motor from the traction network by clicking on the touch screen and stop using it. Moreover, this kind of microcomputer control technology of locomotive is relatively advanced in China. Secondly, the locomotive power supply system is added at the back of the cooling room of each DF11g. The power supply diesel engine imported from MTU company in Germany is adopted, with constant speed 1500rpm and LSA47. 1 1-4P generator to generate 380V alternating current, which supplies power to the train through two paths (one for each locomotive), and at the same time increases the stability of train power consumption. Thirdly, the car has also made many improvements in improving the comfort of locomotive crew. In addition to the use of standardized cab and imported high-grade seats, there are some other humanized designs. Because of reconnection, one cab was cancelled and the other cab was arranged at one side of the electrical room, which reduced the cab noise caused by the cooling fan. At the same time, some sealing measures have been strengthened, such as gaps in doors and joint areas where some pipes are laid. The biggest point should be the way the air conditioner exhausts. DF 1 1G refers to the design of air-conditioned cars in this respect, blowing the wind out of the window, and the direction of the wind can also be adjusted by the shutters at the air outlet, finally creating the effect of air-conditioned cars. People who have driven must feel more comfortable this way. There is also the windshield window, which is related to the driver's observation. Due to the adoption of the new locomotive head type, the front windshield of DF 1 1G is changed from the original flat DF 1 1 to a circular design, which increases the area, increases the driver's visual angle, reduces dead angles and makes driving safer. Finally, some small details also reflect the humanized goal of locomotive designers. Some analog instruments use electroluminescent lighting, just like the lights of mobile phones; The telephone on the bridge can talk to the car through the connecting line; The vehicle signal display is located in front of the driver's left side. ...
Locomotive front-end air conditioner
The reason why the computer display screen and air conditioning outlet are improved so much is to adapt to the high reliability of locomotives required by the Ministry of Railways for single drivers. It is understood that there will be a major breakthrough in the use of this car in the future. The existing scheme of the Ministry of Railways is that the first batch of DF 1 1G locomotives respectively assigned to Beijing internal combustion section (Beijing section of Beijing Railway Bureau) and Shanghai locomotive section (Shanghai section of Shanghai Railway Bureau) run in reverse, and each locomotive group contracts different trains. Double drivers are required to run 1463km from Beijing to Shanghai, even from Beijing to Hangzhou without changing locomotives, only changing drivers once in the middle. In this way, new management methods will also appear in the settlement methods between railway bureaus.

Most domestic railway enthusiasts call Dongfeng 1 1G locomotive "pig's head", which comes from the Chinese phonetic abbreviations of "straight (z) dart (t) fast" and "pig's head" (a large part of the through express trains of China Railway are composed of DF 1 1G).
