Cummins ISG Engine helps Wu Weidong
About the Yunnan Guizhou Sichuan, new Qinghai Tibet, the first time most people have in mind will emerge out of the beautiful natural scenery, the scenery is in an unbroken line toward the truck! But for people, these are wrapped in beauty under the most dangerous road transport: the changeable weather conditions and frequent on the downhill, high altitude caused the bad driving environment and so on, single out any one, to make every driver a headache, but these for Wu Weidong, but it is easy to control the degree of relaxation.
Shanxi Qixian Wu Weidong, engaged in truck transportation for nearly 20 years, not conservative, dare, dare to make money merchants inherited the world powers. From 1998 to the driver's license to today, only 38 years old Wu Weidong ran all over the land of China, has already become an old driver, a live map. And can easily control the Yunnan Guizhou Sichuan, Tibet and other complex new sections, IBrake braking system of Cummins ISG engine special thanks to Auman GTL super version equipped with.
The domestic heavy truck brand on a circle of Wu Weidong, in November 2014 bought Auman GTL super version 6X2 380 horsepower tractor. "It was to go to this engine at that time, to run the western region or to Cummins." Wu Weidong said that in the next 16 months, the 230 thousand km operation also proved Wu Weidong's choice was right. But in Wu Weidong's heart, choose equipped with Cummins ISG engine Auman GTL super version has not the right to describe, but the treasure!
The unique IBrake brake system of the special Cummins ISG engine makes his transport mode change qualitatively. Trailer away water shower, the brakes do not need to change, about 200000 kilometers southwest of Qinghai Tibet Road on a steep slope break, so natural for me to believe, and Wu Weidong's secret is to fully understand the Cummins ISG engine, the engine "temperament" do bole!
Wu Weidong said: "the Brake braking system is different from the common brake effect through the exhaust brake valve" breath ", it is through the integration and compression brake exhaust rocker arm used to cylinder injection in the compression stroke, the exhaust valve opens later, eliminating the compressed gas energy rebound, increases the efficiency of engine brake. In this way, engine braking can continue for a long time, and no exhaust back pressure will be too high, resulting in excessive temperature of fuel injector, cylinder head and supercharger.
Moreover, the iBrake engine brake also has two stalls: when the first gear is in position, it starts the 4 cylinder engine brake, and produces 66% engine braking force, which is suitable for gentle slope. In the second place, start the 6 cylinder engine produced 100% engine braking, braking force, the braking force can provide additional 370 horsepower, the exhaust brake efficiency is 50% higher than that for the steep slope. But in actual driving process, Wu Weidong will according to road conditions and the engine speed can be real-time and accurate control, the general will be on the 2100r/min under the control of engine speed, then the maximum engine braking efficiency, when the speed dropped to 1800r/min on, to improve braking performance by foot brake pedal or downshift. With a deep understanding of the engine, Wu Weidong realized the 6 foot brake downhill on a 30 degree steep downhill section of a section of a Qinghai Road, which surprised the colleagues at the same time, and even impressed the Cummins ISG engine.
The last 20 years of the wheel life, let Wu Weidong master a lot of car tricks, playing IBrake engine braking is the unique enjoyment brought by the ISG engine of Cummins. In addition, a 35L low temperature fuel tank is installed on the vehicle to heat the main oil tank, so that diesel oil can be used in the long winter in the northwest. At the same time, the auxiliary fuel tank is installed at the bottom of the frame, and the low price diesel is reserved to deal with the long-distance transportation, which greatly reduces the fuel cost. And with the needs of the times, Wu Weidong is also actively adapting to the logistics mode under the Internet, through the freight App to achieve logistics orders. Wu Weidong, who is good at studying, has realized the flexible application of the Cummins ISG engine, so that his transportation is relaxed.
