“As a bridgehead for Southeast Asia, Guangxi Beibu Gulf has great opportunities for development, and the pulling effect on commercial vehicles is gradually emerging.†Luo Ping, Director of the Guangxi Office of Yuchai Corporation, said that although the direct effect of the “One Belt and One Road†is not yet obvious, , but the outlook is promising. He cited the cooperation projects of Liugang and Wuhan Iron and Steel at Fangchenggang and the reclamation project at Qinzhou, the joint venture industrial park between China and Malaysia and Singapore at Qinzhou, and the year-on-year growth of the trade volume for Guangxi in Southeast Asia. Produce pulling action.
As the sole distributor of the Dongfeng Liuzhou Commercial Vehicle brand, Lu Yong, deputy general manager of Guangxi Chaoda Anji Automobile Sales Co., Ltd., said that as the "Belt and Road" front station struggles for the Beibu Gulf logistics market, the future of heavy truck-related companies is "in the vicinity." The competitive landscape in One Way has an important influence. He said frankly: "If we want to wait for market highlights this year, our biggest expectation is that the 'Belt and Road' initiative will lead to investments in infrastructure, transportation and other areas."
Liu Zhigang, deputy general manager of Dongfeng Liuzhou Automobile Sales Company, told reporters that in order to seize the “One Belt and One Road†development opportunity, Dongfeng Liuqi’s China V fuel vehicles supporting Yuchai’s engines are also ready, and will be launched successively in Beijing, Shanghai and other markets starting next year. . The lightweight new product, the Long M7 heavy-duty tractor, will also carry the Yuchai 6MK400 hp engine. The model is benchmarked to international standards and is aimed at replacing imported products. It will compete with Volvo and other international brands. "In Shenzhen, Guangzhou, Guangzhou, Qinzhou, Guangxi, Beihai, Fangchenggang, Ningbo, Zhejiang, and other port vehicles, we Dongfeng Liuqi are mostly equipped with Yuchai machinery." Liu Zhigang said that in the coastal ports, especially the Pearl River Delta, the Yangtze River Delta coastal The port, with a prosperous economy, has a high demand for vehicle emissions, and the car is “very pickyâ€. It is both efficient and fuel-efficient. The Yuchai Engine satisfies the needs of users.
According to Guo Bin, general manager of Dongfeng Liuzhou Commercial Vehicle Dealer and Guangxi Yulin Yuchai Machinery & Electrical Co., Ltd., Guangxi also undertook the transfer of Guangdong's industries. Large enterprises such as cement and ceramics have been built and put into production in Guangxi in recent years, such as China Resources Cement and Conch. Each single item of cement has reached a million-ton level, which has brought greater demand for road vehicles. For example, he said that one company engaged in the transportation of bulk cement and powder tanks had only five vehicles three years ago and used other brand models, but it had a heavy body, high fuel consumption, and insufficient power. Later, Yuchai and Dongfeng Liuzhou conducted a follow-up analysis of the entire transportation process and replaced Dongfeng Liuqi tractors with 375-horsepower Yuchai. In a year, the cost of bicycle savings was as high as 60,000 yuan. This is equivalent to a Yulin truck. Driver's salary for one year." By the end of last year, the company already had more than 120 vehicles. “More than 20 new vehicles have been added since the beginning of this year, and the demand for power has been increased to 400 horsepower. The adoption of Yuchai’s recommended matching package is still used,†said Guo Bin.
The Dongfeng Liu Auto Truck equipped with a Yuchai engine also gained users' favor because of its lightweight advantages. According to Guo Bin, a team engaged in transportation of vegetables in Yulin is very sensitive to the quality of vehicle maintenance. Under the standard load, the Dongfeng Liuqi M5 truck carrying the Yuchai 6MK engine is about half a ton lighter than other brands. "Dora Run" improved the operational efficiency of users.
Liu Zhigang stated that he expects Yuchai to align with and surpass the leading level of international power suppliers. The high efficiency, fuel-saving, service-friendly and user-friendliness brought about by lightweighting and tailoring show that the vision of “Excellent Quality, International Yuchai†is accelerating.
The piston is one of the main moving parts of the
engine, is composed of combustion chamber components.
The pressure of the gas
piston through the connecting rod to the crankshaft, realize the change from
heat energy to mechanical energy.
The work condition is very bad, and the
temperature of 1400-1800 DEG C, and pressure
Up to 13MPa above the gas
contact, greatly alternating thermal stress and mechanical stress.
And by the
serious corrosion of gas, and under the condition of boundary lubrication and
cylinder wall friction and strong impact 1 times.
The piston in high
temperature, high pressure, strong corrosive gas contact so that it has enough
strength and hardness,
Heat resistance and good thermal resistance, high
fatigue strength and corrosion resistance. For high speed Diesel Engine Piston
also requires light as far as possible.
In order to reduce the inertia
force.
Marine piston large low speed diesel engine of the crosshead is
usually combined.
The heat treatment process by normalizing and annealing,
and iron pearlite are ferrite organization, has good heat resistance.
Piston
alloy quenched and tempered steel has better heat resistance and corrosion
resistance. The skirt with nodular cast iron annealing treatment, with good wear
resistance.
