China National Heavy Duty Truck started to develop gas engines since 2002. In 2005, it successfully developed heavy natural gas engines. In 2008, China National Heavy Duty Truck Natural Gas Engine Project was included in the National 863 Plan. In June 2011, it passed the acceptance of the Ministry of Science and Technology. Through the 863 Program, CNHTC's dedicated natural gas engine has achieved breakthrough results in terms of power, economy and environmental protection.
Heavy duty WT615 series natural gas engines are the largest natural gas engines in the country and have a 45%-50% market share in the domestic heavy truck market. They can be used in tractors, dump trucks, concrete mixers, and trucks. The product sales area covers the whole country, especially in regions rich in gas sources such as Xinjiang and Shanxi, and also exports to Southeast Asian countries such as Thailand, Singapore and Malaysia. At present, the number of heavy-duty natural gas vehicle vehicles in Thailand reaches more than 2,000 vehicles.
China National Heavy Duty Truck Division RM Engineer Ma Peng is a member of the WT615 engine R & D design team, according to him, at present, China's heavy truck WT615 series of 10L, 12L two series of 12 models, rated power 170KW to 309KW, which means that the maximum power can reach 420 horsepower, is the highest power in the domestic equivalent displacement engine. Compared with other natural gas heavy-duty engines in China, the WT615 natural gas engine features high reliability, more powerful power, and more economical and environmentally friendly features. The advantages are obvious.
The WT615 natural gas engine inherits the reliability of the original diesel engine. It uses an internal coolant piston and a specially designed piston ring. It uses a water-cooled exhaust turbocharger to extend its service life. It adopts a four-valve structure, a spark plug, and an intake manifold. High gas efficiency, more complete combustion; matching the perfect supercharger, together with the electronically controlled exhaust valve device, makes the large torque value and large torque speed range basically consistent with the same power diesel engine; its lean combustion, electronically controlled pressure regulator The gas mode makes the engine have a very good fuel economy, and the minimum specific gas consumption is less than 185 g/kWh, which saves the user the cost of use; the emission level is better than the limit of the National IV regulations.
WT615 natural gas engine products have wide applicability. They can use compressed natural gas (CNG) or liquefied natural gas (LNG) as fuel to meet the needs of different users. The use and maintenance cost of engine gas control system is low, and the system is adaptable. “Under the conditions of unsatisfactory gas source quality and poor working conditions in China, CNHTC WT615 series natural gas engines can also work well, which is one of the main reasons why users favor our products.†.
The WT615 series products have undergone rigorous engine bench durability test and vehicle road test before being put on the market; 100% bench test is performed before the engine leaves the factory; the gas control system adopts the products of American ECI company with high reputation in the world, To ensure the best quality.
â— In response to market trends, the sales department is pushing for gas vehicles
After several years of development, CNHTC's natural gas heavy truck technology has gradually matured, and it can fully meet the demand for heavy-duty and heavy-duty trucks. At present, China National Heavy Duty Trucks HOWO, Gold Prince, Haoyun and mining vehicles, dock low-speed tractors, buses and other models have mature gas vehicles.
The regional subsidiaries of CNHTC's various sales divisions actively cooperate with the regional natural gas energy companies to conduct a series of promotion activities. This year, companies from Shandong, Tianjin, Shanghai, Shenzhen, and Beijing have organized their customers to visit Jinan. Through visiting production bases, customers have witnessed the strength of CNHTC and natural gas products.
With the increase in the sales volume of natural gas products, CNHTC established corresponding promotion demonstration points according to different operating conditions of gas vehicles: a coal transportation tractor demonstration site was established in Shanxi; a demonstration site for dangerous goods transport tractors was established in Jiangsu; in Henan A road transport dump truck (8×4) demonstration site was established. With the use and availability of vehicles, demonstration vehicles for mixing trucks will be built in Beijing and Jiangsu, and demonstration sites for heavy-duty tractors will be available at Shandong Zibo. Through on-site inspection of the demonstration sites, gas vehicle users truthfully introduced the operational benefits brought by the gas vehicles, which effectively promoted the sales of gas vehicles. China National Heavy Duty Truck Sales also established a special consultation telephone for gas vehicles to solve practical problems in the technical knowledge and product characteristics of natural gas products of branches and outlets.
In March, China National Heavy Duty Truck Sales Co., Ltd. facilitated the signing of a strategic cooperation agreement with two large domestic energy companies. Through the strategic cooperation with energy companies, it promoted the sales of CNHTC's gas vehicles. Not long ago, Jinan Haowo Bus Company delivered 10 gas buses tailored for Mianyang Bus Company to users. The Zhengzhou Branch of the Jinan Commercial Vehicle Sales Department and CNPC Kunlun Energy held a gas LNG promotion meeting in Zhengzhou, focusing on the introduction of King Prince and HOKA 7 series LNG vehicles.
The scene reached an intention to purchase more than 40 vehicles. On March 29, Jining Commercial Vehicle Company formally delivered 10 Haoyun LNG natural gas heavy trucks to Xiamen Port Group, becoming the first natural gas heavy truck in Xiamen. “The logistics industry in Xiamen is well-developed and we are optimistic about the Xiamen market.†Cao Changxin, general manager of CNHTC Jining Commercial Vehicle Sales Department, revealed that before the handover ceremony, a private company that participated in the meeting also reached a preliminary agreement with them to order 30 heavy trucks. .
â— Users prefer CNHTC Gas Vehicle after comparison of advantages
Tangshan City, a cement transport company currently has more than 300 vehicles, including 50 CNG heavy trucks and more than 200 diesel vehicles for the heavy truck brand. Mr. Zhang, who is in charge of vehicle management, said, “The company’s CNG vehicles were originally recommended by manufacturers. After trials, they found that heavy truck natural gas heavy trucks not only saved costs, but also did not lose diesel power. Therefore, they decided to purchase HOWO CNG vehicles.â€
Mr. Zhang said that CNHTC's natural gas engine is suitable for the country's current trend of loading and unloading of goods. The purchase has been in good use. In addition to normal maintenance, there is no major fault. “We transported bulk cement between Tangshan and Beijing. Under the same conditions, the natural gas engine will save three or four hundred yuan over the diesel engine.†Mr. Zhang said: “The cost of maintenance is similar to that of a diesel engine. Parts and accessories are cheaper than diesel engines. Slightly more expensive, but long life.â€
Mr. Zhang is also very satisfied with the service of CNHTC: “Our company has both passenger and cargo transportation business. Comparing the two, the after-sales service of the CNHTC is much stronger than that of the passenger bus. There are plenty of accessories and timely service. There is a company near the company. The steam service station provides services 24 hours a day. Whenever a call is made, it will soon be in place.†The vehicles of Tianjin Dagang Oilfield Transportation Co., Ltd. Gas Subsidiary are all identical to China National Heavy Duty Truck. Among the 20 diesel vehicles, there are 4 King Steyr and 16 Howough, and another 5 Howow natural gas tractors have just been purchased in the past two years.
"Heavy duty engines have reliable quality, few failures, and relatively low fuel consumption." Wang Xinquan, manager of the branch, told reporters. The company has done statistics that the existing five natural gas heavy trucks can save about 40% of fuel consumption compared with diesel vehicles. "Moreover, the use of these vehicles has not been a big problem except for the replacement of spark plugs." Wang Xinquan added. Wang Xinquan intends to retain only a few heavy-duty diesel vehicles for the long-distance business, and the rest will be replaced with models equipped with heavy-duty gas engines for applications within a radius of 300 kilometers.
The Shanxi Jinzhong Logistics Co., Ltd. Jinzhong area has now become a beautiful landscape on the Jinzhong Highway. “Our boss had bought 300 diesel vehicles before and sold them all, replacing them with LNG vehicles from China National Heavy Duty Truck,†said Li Cunniu, the company’s chief engineer.
Jin Coal's original 300 diesel vehicles. In preparation for switching to a natural gas heavy truck, the company’s leaders selected four brands of vehicles including China National Heavy Duty Truck to test for one month, eventually winning CNHTC's natural gas power. Li Cunni introduced that since the WT615 series has a single-cylinder power of 35 kilowatts, the 340-horsepower engine of the heavy-duty engine is more powerful than the ordinary 380-horsepower natural gas engine.
Heavy-duty natural gas engine parts are also very durable. "The heavy-duty 340 hp natural gas engine was developed by Heavy Duty Truck and developed in cooperation with Econtrols in the United States. The spark plug has effectively solved the problem of leakage, and the sustainable use of 70,000 to 100,000 kilometers is 1.5 times more than that of the normal engine." Li Cun Ni introduced. In terms of fuel consumption, CNOOC's 100km fuel consumption is 180 yuan less than diesel engines.
According to Ma Peng, an engineer of China National Heavy Duty Truck Power Division, there are two main combustion methods for natural gas engines in China. CNHTC's WT615 series adopts a four-valve structure with electronic pressure-adjusted intake air compared to two-valve, injection air intakes. With the engine, the fuel burns more fully, the gas consumption is reduced, the economy is more prominent, and the power is stronger. At the same time, the system maintenance cost of China National Heavy Duty Truck's WT615 series products is also relatively low. “The jets will need to change their nozzles when they run 56,000 kilometers. A nozzle costs more than 10,000 yuan, and the heavy-duty engine is just normal wear and tear. The ignition coil is also about a thousand dollars, giving users a lot of money."
â— Look forward to policy support
Due to lack of clear policy support, the development of natural gas heavy trucks has been driven by truck companies and markets. “At present, the situation facing heavy-duty trucks in China is welcomed by users. The gas supply companies are pushing and the vehicle manufacturers have enthusiasm. Many local governments also strongly support it. Only national policies neither support nor oppose it. Wang Deqian, general manager of the Ministry of Power, told reporters.
The development of natural gas heavy trucks is truly "Everything is ready, but only the east wind." A related person of a heavy truck company also stated: “We have been calling for the integration of natural gas vehicles into the scope of new energy vehicles and enjoying state subsidies. From the perspective of the effects of energy saving and emission reduction, the advantages of natural gas heavy trucks are obvious, and the mining and use processes are pollution-free. Although electric vehicles are zero-pollution in use, there is pollution in power generation and battery recovery. Moreover, although China's natural gas reserves are abundant, there is a big gap between its use efficiency and the international level, and there is room for improvement.
Therefore, the person hopes that the government will increase efforts to support the industry chain to encourage the development of natural gas heavy trucks, both to provide support for the technological development of innovative companies, and to give energy companies support in the construction of gas stations, and at the same time, Give the user a subsidy. "Now the natural gas heavy truck is 80,000-100,000 yuan more expensive than a diesel vehicle. If you can get a subsidy and lower your procurement costs, your enthusiasm will be even higher."
