Under the current situation of the national “Twelfth Five-Year Plan†for energy saving and emission reduction, in 2013, Xilinhot Mining Co., Ltd. Datang Coal required that all dump trucks entering the Datang Coal Mine be equipped with wide-body dump trucks equipped with natural gas engines. Under this premise, on June 9, 2013, 27 Valin's wide-body dump trucks with T12.38 state-four engines from China National Heavy Duty Truck started to enter the mine. “The first time I opened this gas vehicle, it gave me the first impression that it was a strong one. Compared with the diesel cars that were previously with the same horsepower, they were even more aggressive under the same conditions, especially when climbing a hill, they could increase the height of a stall. A driver from Wulanchabu Jining said so. Wang Daxing, chief of the construction of the natural gas team, said: "I did not expect that the natural gas vehicles could be more powerful than diesel vehicles." Under the premise of energy saving and environmental protection, the reliability of the original diesel engine is retained; the internal cooling oil piston and the special piston ring are used; the water-cooled exhaust turbocharger is used to extend its service life; Combustion, high thermal efficiency, low temperature, full closed-loop control plus self-study and self-diagnosis functions, dual platinum electric spark plugs, high combustion rate and long life. In the Datang Coal Mine, the depth of 120 meters, the distance of 8 kilometers, 14 yuan per square soil, a vehicle filled 23, that is to say a user can get 322 yuan (including fuel). How to make more money, in the hearts of users own an abacus: diesel vehicles run a fuel consumption of 20L, 1L diesel 7 yuan, then every time you run, need to spend 140 yuan; natural gas vehicle running a gallon consumption is 18 Kilograms, 1 kilogram of gas 6 yuan, the total count, it takes 108 yuan. In this way, every trip can save 32 yuan. When one day goes by, the user can save 736 yuan. Therefore, natural gas vehicles have an inherent advantage in economics. At present, the driver does not fully adapt to the gas pedal of the gas vehicle. After a period of adaptation, the gas consumption can be further reduced. In the mining area, all vehicles are working 24 hours a day. High-intensity, long-term, poor road conditions and poor environment. It is common for vehicles to stop in tunnels due to faults. The mining area requires that parking on major roads not be allowed to fail due to breakdowns. 5 hours. Therefore, after-sales service personnel stationed in the mining area, since the receipt of service calls, must arrive at the scene of the fault within an hour, service personnel are often used because of the maintenance time is too short to eat, add night work, rain maintenance is a matter accustomed to. It is because of this “convention†spirit that users are very trusting in our engine products. Guo Tang, the Natural Gas Vehicle Project Department of Datang Coal Mine Grand Construction Group, said: “In all after-sales service, engine service is the best. of". In fact, in this case, the project department equipped with China National Heavy Duty Diesel Engine is also often heard, such as China Construction Sixth Bureau, Liaoning Coal Construction, China Railway 20th Bureau, is such a service concept, established a heavy truck engine in the big The service word of Tang Coal Mine is “one step, step by stepâ€. CNHTC's engine business leaders attached great importance to this batch of Valin gas vehicles and sent service managers and technicians to track the use of all Valin's natural gas vehicle engines in the mining area. They demanded that they first go to the fault site to find out where the problem lies. Timely and effective solution to engine failure. Baotou Branch Director Xu repeatedly visited the construction site of Datang Coal Mine to guide the after-sales service of the engine. China National Heavy Duty Truck Group Hangzhou Engine Sales Headquarters often calls for information on the use of the engine, encourages first-line service personnel to do a good job of engine after-sales service, and promotes Hangfa Power's popularity in Xilinhaote, Inner Mongolia. At present, China National Heavy Duty Truck's engine is used steadily in the Datang Coal Mine and has established a good reputation for CNHTC's natural gas engines. In the wide-body mining vehicle market, when many users are buying cars, CNHTC's natural gas motivation has become their preferred power match.
