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 of fuel-saving products developed by the company, the No.2 fuel economy engine, which set off a wave of upsurge for the fuel-saving storm prevailing nowadays . It is reported that at present China National Heavy Duty Truck has commissioned the No.2 engine on the Hao Li series of products and will be the year of its full line of products assembly of the engine. Based on the upgraded engine introduced by CNHTC Group at the beginning of this year and jointly with the most technically-accredited foreign design institutes, the fuel-efficient No. 2 engine is designed and upgraded according to the European mechanical development program and developed according to the characteristics of road transport in China A new generation of independent intellectual property system. After 6000 hours of uninterrupted machine testing, fuel economy II engine minimum fuel consumption reached 189g / kWh, has been in line with European standards. The field test shows that the fuel consumption per 100 kilometers of heavy vehicles equipped with No.2 engine is more than 10% lower than that of domestic similar products, and the torque reserve coefficient increases by more than 30%. Wang Donghui, deputy party secretary of CNHTC, said at the launch site that in the face of soaring oil prices, almost all automobile manufacturers in China have all launched their own fuel-saving products one after another. Some of them actually make real efforts, but others only utilize users The blind spot to follow the trend of cognitive hype, which gives users the choice of suitable products increased difficulty. China's heavy truck launched the fuel-efficient II engine, not only can truly fuel-efficient users, but also its fuel-efficient capacity in the country is also second to none of its kind. Liu Wei, director of China National Heavy Duty Truck Group Technology Center, said the reason why fuel-efficient II engine more fuel-efficient, mainly because of its first use of the 8500 injection pump, and with a bleed valve to replace the turbocharger ordinary increase Compressor, the engine's intake system and fuel supply system to achieve the best match, effectively improving the engine's power and economy. Liu Wei introduced the core of the engine is the fuel pump, the current domestic Steyr other manufacturers are equipped with 7100 fuel injection pump, fuel consumption indicators remain high, can not be significantly decreased. China National Heavy Duty Truck and foreign companies jointly developed a 8500 pump, designed for heavy truck products in China. The 8500 pump has the unparalleled superiority of the 7100 pump. After rigorous testing, the 8500 pump has a significantly better fuel economy than the traditional 7100 pump. The engine bench test features a minimum of 3 g / kWh less fuel consumption and an additional torque reserve factor of 30 %, Acceleration, climbing, overload power is more robust. Liu Wei to reporters forget such an account: Fuel economy II engine compared with the average engine cost price of about 500 yuan, while the fuel consumption per hundred kilometers to reduce 5 liters, assuming a car running 150 kilometers a day Can save 8 liters. According to the current market price of oil, the day savings of about 35 yuan of funds, less than a month, the cost of 500 yuan will be able to save the cost down. It is reported that the introduction of new products at the same time, China's heavy truck sales hit record highs. From January to July this year, CNRT has produced and sold 35,385 heavy trucks, representing an increase of 39.12% as compared with the same period of last year with a market share of 20.37%. Its sales revenue reached 12.767 billion yuan, an increase of 77.4% over the same period of last year. Its profits and taxes were 930 million yuan, An increase of more than 200 times; exports of 4764 vehicles, foreign exchange earnings of 132 million US dollars, an increase of 9 times.
