Who is afraid of Cummins on the Qinghai-Tibet line?

Which section of the country is the most challenging? It is the rainstorm in South China, the frequent downhill in the southwest, the economics of the plains in North China, the ice and snow in the northeast, and the wind and sand in the northwest. The vast land has been given to different regions and different truck people. Car habits have also produced the "temper" of different brands of heavy trucks.

As we all know, each model must pass the "three highs" (plateau, alpine, high temperature) test before going on the market. The Qinghai-Tibet line as a plateau test section is a "compulsory course" for every model. In the just-concluded second Qinghai-Tibet line climbing competition, the Cummins ISZ 13 power and Cummins X12 power led by Tianlong flagship and Auman EST super truck were all in full swing, and five of the top ten in the climb were won. The number of places is what makes the power from North America to win trust in a unique high-altitude area, which has a far-reaching relationship with respecting the market in the Qinghai-Tibet region.

In the second session of the Qinghai-Tibet line climbing competition, the sixth-placed Auman EST equipped with Cummins X12

Striving for stability

On the Qinghai-Tibet line, heavy-duty trucks with high horsepower tend to have advantages. This point can also be compared from the two climbs. In the first competition of 2015, the maximum horsepower in the domestic market was 430 horsepower, and the Qinghai-Tibet line was much higher than the mainland market. Up to now, more than 500 horsepower models are everywhere, especially the "fierce" Tianlong flagship, equipped with a 13L ISZ engine, 560 horsepower output, in high altitude, low air pressure, low oxygen content environment, Large reserve power makes it easier to overcome “altitude sickness”. Even at an average elevation of 4,700 m above the Kunlun Mountain Pass, even in the face of harsh external conditions, the vehicle will be under-powered and even prone to "opening" in the case of the east wind , the Dongfeng Cummins ISZ and the Foton Cummins X12 supercharged system and The comprehensive performance of cold technology is good, and it has not been greatly affected in terms of fuel economy and smoothness, which has a lot to do with the quality of ISZ and X12 products themselves.

Foton Cummins X12 engine

The maximum horsepower of the Dongfeng Cummins ISZ series engine is increased to 560 hp, the maximum torque is increased by 5%, and the low-speed torque is increased by 400N.m. It is more powerful to start overtaking. The ultra-high pressure fuel injection system, extremely small combustion particles and extremely fast injection speed make it more efficient in combustion and breakthrough in power. For the climbing of the Qinghai-Tibet line, even under heavy load, the power is still quite high. Strong, coupled with more than 10 million fatigue tests of key components, reliability is undoubted, if you encounter a good driver, at the same time, pay attention to driving habits to avoid not boiling, get the crown is reasonable.

The champion power Dongfeng Cummins ISZ is naturally sound, and the Foton Cummins X12 is not bad. The Fukang X12 engine is Cummings' exclusive power for American super trucks based on its X platform heavy-duty power, the global 10-15L engine range. The Foton Cummins X12 engine adopts iBrake compression brake and integrated engine design, and the braking force can be increased to 400 hp. In addition, the engine adopts low-speed and high-torque design, which can achieve 2300 Nm of torque output at 1000 rpm. Providing continuous power, even in the process of filling up the goods and climbing the plateau, the power can be satisfied; it is reported that the engine adopts MFS's new integrated machining high-efficiency turbocharger and full-machine processing high-efficiency impeller. Can greatly improve the reliability of the operation process. In addition, the compression brake and the integrated engine in-cylinder brake make the control precision higher, the engine cylinder brake efficiency is improved, thus improving the safety, not only the power is enough, but also the reliability and safety blessing, even if The air is thin, even if the climb is laborious, the Fukang X12 can go on the road.

Dongkang ISZ and Fukang X12 double swords, Cummins Power is not afraid of the heavy truck market.

Dongfeng Cummins ISZ is not only "big", but also remembers the strength of the Qinghai-Tibet region to bring good reputation.

The reason why Dongfeng Cummins was raised separately is because, in fact, Dongfeng Cummins does have a profound market foundation in the Qinghai-Tibet region. This is mainly due to the fact that Dongfeng Commercial Vehicle has contributed its strength to the construction of the Qinghai-Tibet area since its establishment. Whether it is transporting concrete, steel and other building materials or food, it has always been the main force.

Dongfeng Cummins ISZ engine

For decades, from the matching Dongfeng Bapingchai to the current Dongfeng Tianlong series, the performance of the Dongfeng Cummins engine for the altitude sickness is not only praised by the drivers, but even the earliest backpackers. Everyone knows that the "winding" must choose the engine of Dongfeng Cummins, and the cold start, reliability and power are guaranteed. Known as the "God Machine" is also caused by word of mouth.

Since the first medium-sized B-series Cummins engine was produced by Dongfeng and Cummins in the 1980s, more than three million Dongfeng Cummins engines have been deployed throughout the country. The service network and spare parts network are everywhere. Areas such as the plateau where the natural environment is relatively harsh are the key support, which also brings better service and supply to the racing vehicles. In the same way, it can also let the Dongfeng commercial vehicle model running the Qinghai-Tibet line enjoy better service and supply, and apply a more poetic words. This is probably to forget the Qinghai-Tibet region, and the deep cultivation will have a return, and the good market will have a resounding .
