In the workshop hall of China National Heavy Duty Truck Group Jinan Power Co., Ltd., China National Heavy Duty Truck officially launched a new-generation fuel-saving product developed by the company, the fuel-saving II engine, which has set off another wave of fuel-saving storms that are now prevailing. climax. It is reported that China National Heavy Duty Truck has assembled the fuel-saving II engine on the Haohao series of products, and will assemble the engine for its full line of products during the year.
The fuel-saving II engine is based on the upgraded engine launched by China National Heavy Duty Truck Group at the beginning of the year. It is combined with the most technically authoritative foreign design institutes, designed and upgraded according to the European mechanical development program, and developed according to the characteristics of Chinese road transport. A new generation of power systems with independent intellectual property rights. After 6000 hours of uninterrupted machine testing, the fuel consumption of the fuel-efficient II engine reached 189g/kWh, which has already met European standards. The field test shows that the fuel consumption per 100 kilometers of heavy-duty vehicles equipped with fuel-efficient II engine is reduced by more than 10% compared with domestic similar products, and the torque reserve coefficient is increased by more than 30%.
Wang Donghui, deputy secretary of the China National Heavy Duty Truck Party Committee, said at the product launch site that in the face of rising oil prices, almost all domestic automakers have launched their own fuel-saving products, some of which have indeed made real efforts, but some just use users. The cognitive blind spot follows the trend, which makes it more difficult for users to choose the right product. China National Heavy Duty Truck's fuel-saving II engine not only can really save users fuel, but its fuel-saving capacity is second to none in domestic similar products.
Liu Wei, director of China National Heavy Duty Truck Group Technology Center, said that the reason why the fuel-saving II engine is more fuel-efficient is because it used the 8500 fuel injection pump for the first time and replaced the original increase with a supercharger with a bleed valve. The pressure device optimizes the engine's intake and fuel supply systems, effectively improving the engine's power and economy.
Liu Wei introduced that the core of the engine is the fuel injection pump. At present, other domestic manufacturers of Steyr engines are equipped with 7100 fuel injection pumps, which keeps the fuel consumption index high and cannot be significantly reduced. China National Heavy Duty Truck and foreign companies jointly developed 8500 pumps for the use of China National Heavy Duty Truck products. The 8500 pump has the superiority that the 7100 pump can't match. After rigorous testing, the 8500 pump is more effective than the traditional 7100 pump. The engine bench test has the lowest external fuel consumption and the fuel consumption is reduced by 3g/kWh, and the torque reserve coefficient is increased by 30. %, acceleration, climbing, and overloading are more powerful.
Liu Wei gave the reporter such an account: the cost of the fuel-efficient II engine is about 500 yuan higher than that of the ordinary engine, and the fuel consumption per 100 kilometers can be reduced by 5 liters. Assuming that a car runs 150 kilometers a day, Can save 8 liters of oil. According to the current oil price on the market, the amount of money saved in one day is about 35 yuan. In less than one month, the cost price of 500 yuan can be saved.
It is reported that while the launch of new products, the production and sales of China National Heavy Duty Truck is also a record high. From January to July this year, China National Heavy Duty Truck produced 35,385 heavy trucks, an increase of 39.12% over the same period of last year. The market share reached 20.37%; the sales revenue was 12.767 billion yuan, up 77.4% year-on-year; the profit and tax was 930 million yuan. It has grown more than 200 times; it exported 4,764 vehicles and earned US$132 million, a nine-fold increase over the same period last year.
JHK Door Industry Beech Veneer Door Skin is popular used to produce nice and classical veneer molded door. Beech veneer is very popular in European and American market. In order to make good Door Skin, we use good fiberboard and glue, after two times high temperature, the beech veneer will stick on the fiberboard perfect.
Beech in Europe is like Oak in North America. It grows everywhere and gets used for just about everything. It works especially well with accent woods that have a contrasting color, like Mahogany. We pretty much always have plain sliced, plain quarter (rift) and figured in inventory. We favor steamed over unsteamed as do most of our customers. Figured sometimes has such strong character that it will display some lighter grain tones. This is a great wood veneer that isn't that hard to work with and can be used in large doses with little consequence other than having the ability to look very clean and fresh.
