As a new generation of long-distance transport tractors for Dongfeng Commercial Vehicles, Tianlong flagship has been delivering its “efficient†performance to the general public since its launch at the Shanghai Auto Show in 2013. What is the actual situation? Recently, China Truck Network The Dongfeng Tianlong flagship 450 horsepower 6X4 tractor will take you to experience the "core" strength of Tianlong flagship equipped with Dongfeng Cummins ISZ13 litre engine. Vehicle Profile: Cardmates often say: "Choose a car is like asking a wife, not the best, only the most appropriate!" This also applies to the flagship of Tianlong, to let you see the officer to better understand the flagship of the next Tianlong In terms of performance, we first make a brief description of the parameter configuration, operation route, and road environment of this vehicle. The follow-up vehicles come from the famous Luzhou Sanjiang Logistics Co., Ltd. in the cold-chain logistics industry. Sanjiang Logistics relies on large enterprises such as Yili, Sanquan, and Siyuan to build cold chains in Zhengzhou, Shenzhen, Xi’an, Yinchuan, Lhasa and other regions. Logistics line, strong. The company owns more than 70 self-operated transport vehicles and mainly models Dongfeng commercial vehicles. Among them, 8 high-end heavy truck Tianlong flagships mainly undertake long-distance trunk line cold chain distribution. All of them are fitted with ISZ 13-liter engines produced by Dongfeng Cummins Engine Co., Ltd. Very high. China Truck Network reporter summary : From the perspective of vehicle configuration alone, the Dongfeng Cummins ISZ engine is undoubtedly the biggest highlight of the car, 13L large displacement engine brings high horsepower, high torque and a wide range of low-speed economic operation is other products The "congenital deficiency." At the same time, the world-class parts and components assembled by the vehicle, and the technical innovation and manufacturing experience of Dongfeng Commercial Vehicle for more than 40 years, the product is worthy of users' trust. Stability: speed can be low 200rpm efficiency is completely ok On the same day as the car, there was a Tianlong flagship full of Sanquan food that needed to be sent from Zhengzhou to Jining. Because the distance between the two places was relatively close, the drivers decided to take advantage of the night and set out to start the night. Master Wang and Master Li are both The senior driver with more than 20 years of actual driving experience knows the driving performance and performance of various domestic models. At around 19:30 on the same day, the Tianlong flagship with a total cargo weight of 47.2T departed from the Sanjiang Logistics Park. After a short period of high-speed congestion around the city, the company went straight to Lianyungang Expressway and headed to Jining for more than 330 kilometers. Mainly, there are occasional ramps and road construction, traffic flow at night is generally good, and road conditions are generally good. Such transportation conditions are simply “a piece of cake†for the “armed†Tianlong flagship, which takes only 5 hours to arrive. Jining unloading area, which in the Lankao service area due to shooting needs to stay for about 30 minutes. In the follow-up process, although the pilot of the shift master season was just transferred from other cars to driving Tianlong's flagship, he was not particularly familiar with Tianlong’s flagship performance, but he also talked about the feeling that Tianlong’s flagship brought to him as “stability. â€: Stable overtaking, stable climbing, and stable vehicle performance. The feeling of “everything is under control†feels good. At the same time, Season Master also reflected a "problem" to us, that is, the engine speed of Tianlong's flagship was a bit low. At a speed of 80km/h, the speed of the Dongfeng Cummins ISZ 13L engine is only 1050rpm, which is 100-200rpm lower than that of the previous driving of the seasonmaster; and when the speed is overtaking, the speed is only 95km/h. 1250rpm up and down, compared to the season before the master driving the speed of the vehicle should be at least 200rpm or more, and has been driving Tianlong flagship driving more than 100,000 kilometers of the master Wang has long been "see through" all this, to explain to us that this performance thanks to the east wind The large displacement output of the Cummins ISZ13L allows the engine to output high torque at lower speeds, not only at low speeds, but also at a faster engine start, faster acceleration during driving, and stronger climbing ability, in other words " Pull far more and run faster." China Truck Network Reporter Summary : "Steady" is a calm strength and a manifestation of high efficiency in transportation. The confidence of Tianlong’s flagship comes from the leading “coreâ€. Dongkang ISZ13L golden power engine can output maximum torque of 2238N·m at a speed of 1000-1300rpm, leading to strong power. In terms of fuel injection technology, the Ultra High Pressure (XPI) fuel injection technology jointly developed by Cummins and Scania is used, the injection pressure is 2400bar (typically up to 1800bar in the industry), and the ultra-high pressure injection system atomizes the fuel. Better, resulting in smaller fuel particles and faster injection rates, allowing the fuel to be more fully burned, a major breakthrough in power. Static: Noise is only 68.6dB Tianlong's flagship driving comfort has been recognized by users since its launch. In the actual follow-up car, we also personally feel Tianlong’s flagship “core†comfort. Easy to ride 4 people in the cab, flat floor cab space is spacious. At the same time, although the driver’s response during the season was five hours in a row, physical fatigue was not as strong and it was a lot easier than driving a vehicle. The comfort of the vehicle was evident. The Wang Master who drives Tianlong's flagship for 9 months already regards this place as a "comfortable mobile home," and the quality of sleep has been significantly improved, saying that it is not for other models to drive! When talking about Master Wang's sleep quality, I have to say that Denon's flagship noise performance. Master Wang said: "Before lying in the back berth rest, the strong roar of the engine is in your ear, and you can't fall asleep until you turn. Although the Dongfeng Cummins ISZ13L engine has a large displacement, but the engine noise has become smaller, while with the vehicle The perfect combination of the cab, driving noise is effectively controlled.†And we also made a real environment test for Tianlong’s flagship cabin noise control capability. At speeds close to 80km/h and engine speed at 1050rpm, cabin noise is only 68.6dB, performance better than domestic products 4-5dB, almost the same as imported cars, no wonder Wang master's sleep quality improved. China Truck Network reporter summary: noise, vibration, comfort, is a comprehensive issue to measure the quality of truck manufacturing, it gives us the truck user's experience is the most direct. Moreover, for vehicles, about one-third of the vehicle's failure problems are directly related to the vehicle's vibration and noise. Obviously, the Tianlong flagship is superior to the same kind in this respect. Among them, the Dongfeng Cummins ISZ engine uses an integral steel piston, which can withstand greater in-cylinder combustion pressure; the surface of the connecting rod adopts powerful shot peening technology, and the tensile strength increases by 30%; the swing roller type tappet body effectively reduces the The impact of the valve and the push rod greatly improves the reliability of the engine. These technologies ensure the excellent quality and environmental adaptability of the engine. Not only that, Dongfeng Cummins Engine also owns Cummins C-Link, a “mysterious weapon†that can help Sanjiang logistics captain grasp the real-time flagship operation of 8 Tianlong mobile phones on the App. It can be seen that we have more than 2,800 vehicles in the past with this vehicle. In the mileage mileage, the accumulated fuel consumption is 960.5L, and the average fuel consumption is 33.66L/100km. It is a normal performance in the fleet. There are more than 32 liters of fuel consumption in other vehicles. At the same time, it includes all parameters that can be read by the engine such as vehicle operating route, cargo nature, load, speed, etc. Cummins C-Link can help you see that it provides data support for fleet daily transportation management and indirectly guides fleet managers to take precautions. To maximize benefits. “Whether the vehicle is good or not, it depends on whether the engine is strong or not! Tianlong’s flagship definition of “high-efficiencyâ€, Dongfeng Cummins ISZ uses a perfect interpretation of six words: reliable, economical, and comfortable. With the gradual increase of the flagship of Dongfeng Tianlong, there will be More and more users feel the power of Dongfeng Cummins ISZ ace power.
Magnetic core plays an important role in the whole motor. It is used to increase the magnetic flux of the inductance coil. Maximum conversion of electromagnetic power has been achieved.The motor iron core is usually made up of a stator and a rotor. The stator is usually used as a non rotating part, and the rotor is usually embedded in the stator's internal position.
