Tell me about my self-driving skills in driving my car mu-X Ranger to the Qinghai-Tibet Plateau!

From June 29th to July 26th, 2020, I drove 1.9T National Five Animal Husbandry Ranger into Tibet from 3 18 Sichuan-Tibet Line, and the Qinghai-Tibet Line went out of Tibet, passing through Sichuan, Tibet, Qinghai and Gansu, about 1 1000 km. ? Crossing plateaus, deserts, grasslands, Gobi, rotten roads and canyons, Shepherd Ranger is an ordinary car without any modification. ? Travel notes and beautiful scenery are not mentioned here. Everyone has his own experience. I just want to talk about the self-driving problem of DPF, which is the key to all the problems of self-driving on the Qinghai-Tibet Plateau. Nothing will happen until this problem is solved. ? Because the shepherd ranger is above 5000 meters above sea level, there is indeed a strike problem. The DPF stops working, which means that the engine is masked and can only inhale, but not exhale, and the engine fails immediately. The car can only crawl in second gear, and it can't shift up or down. ? I walked all the way from the Sichuan-Tibet line to Yadong and Golmud on the Sino-Indian border. After several sections of more than 5,000 meters, I didn't encounter the problem of engine failure. I am full of strength and have never lost anyone. Just when I thought it was all right, I was warned at the 5 100 meter mark in Namco, and the yellow light of the engine came on. I checked the DPF, and it was full of dirt. But the motivation is still there. ? I called Isuzu customer service to ask, and the expert suggested that I immediately go down to the low altitude and use the manual low-grade big foot throttle to boom. ? This move really worked. From 5 100 meters to more than 4700 meters, DPF began to clean itself. Problem solved. ? Because all the way over the mountains, there are ups and downs, giving me the illusion and making me numb. As a result, when the Qinghai-Tibet Line crossed the Tanggula Mountain, it suffered heavy losses. ? At that time, the DPF was full when climbing the mountain. I thought I would go down after going up the mountain, but I didn't expect the DPF to be blocked at 5380 meters at Tanggula Pass, without self-cleaning. Unexpectedly, after passing the Tanggula Pass, the road did not go downhill, but kept winding along the high-altitude section of more than 5,000 meters, about several tens of kilometers, only to go down a little. This section of the road simply does not have the conditions to lower the altitude. At this time, the engine immediately failed and could only crawl in the second gear. ? At this time, I regretted it. I should clean myself up at the foot of the mountain before going up the mountain. Although I have encountered many high-altitude areas above 5000 meters on the 3 18 line, those mountains are conditionally descending. ? So, I summarize as follows: 1. When climbing a mountain pass over 5000 meters, should we check whether DPF has reached the critical point of self-purification? If it is critical, clean yourself up before climbing the mountain. Of course, a short mountain that can go down immediately after going up the mountain is carefree. But really entering the plateau area, the continuous high altitude is the norm. ? 2. It is definitely not possible to take DPF to the new Tibet line. Because there are high-altitude areas there for a long time, if you want to go, you must dismantle DPF or make necessary transformation. If you don't reform, please use my following tricks. ? 3.DPF is self-cleaning and cannot be operated manually. When the road section is not good enough to drive fast, you can use manual low-grade big feet to bomb the throttle to speed up the self-cleaning speed. ? I read a post. There was a man driving a nomadic ranger in western Sichuan, who walked a rotten section with a speed of only 15 km/h and couldn't wash himself. I was so anxious that I finally found an open field and quickly circled 60 kilometers above it. In fact, 15 km can also be self-purified, remember: manual low-grade big feet can be used. You don't need 60 kilometers an hour. The description of the ranger's front baffle says that the self-cleaning speed is 60 kilometers per hour, which is inaccurate. Because, when I crossed Qilian Mountain to Dunhuang, I met a long downhill road, with a speed of 80 kilometers per hour. The DPF was not cleaned at all, but stopped for me. And I couldn't refuel at that time: the speed of taxiing with gears was 80 kilometers per hour, so how could I refuel? This fully shows that DPF self-cleaning has nothing to do with speed, but with increasing the throttle to provide high heat. ? Summary: DPF is expected to be self-cleaning, and it only needs low-level big feet to step on the accelerator, which has nothing to do with speed. ? My ranger is below 4750 meters above sea level, so he can lead an honest and clean life, but not up there. Those who enter Tibet should leave a margin for the car. When driving over mountains and mountains, set the display screen in DPF state, so as to know the DPF state at any time. ? In a word, Ranger is a good car. I dare to walk all the way. I also cook at the edge of the 5200-meter Kajiala Snow Mountain Stream. It is chosen because of its passability, robustness and low fuel consumption. Its weakness, I think now is that DPF can't be operated manually. Automatic things, you actually can't control them. ? The following photos are evidence:
