Recently, Great Wall Motor's 10 millionth engine rolled off the assembly line at the Honeycomb Power Yangzhong Smart Factory, which represents the rapid advancement of Chinese automobile brand technology research and development capabilities. It is a substantial breakthrough for Chinese automobile brands. This represents that China's independent R&D and manufacturing of internal combustion engines has passed the market and The consumer test has reached a new milestone.

Great Wall Motors Honeycomb Power's 10 millionth engine rolled off the assembly line

A perfect power "empire" quietly formed in the launch of the 10 millionth engine of Hive Power.

When a power company achieves a production and sales scale of 10 million units, and at the same time has a full-sequence power product coverage, it may have already laid out the core parts and components field in the relevant industry chain. . In addition to the complete machine, Great Wall Motor's Honeycomb Power products also involve the production and development of core components such as turbochargers and hydrogen fuel cell air compressors of all categories. In a sense, Great Wall Motors Honeycomb Power has opened up the most important "industrialization" mode in the R&D and production process.

Strong core technology empowers the rise of Chinese auto brands

For a car, the core component is the engine. Although China is already the world's largest automobile production and sales market, the engine has always been a technical shortcoming of my country's automobile industry, and the key technology is in a "stuck neck" state. It has even appeared that more than half of the automobile industry has to use the same old Mitsubishi 4G63 engine to maintain . Of course, there are also many Chinese auto companies that choose to cooperate with international auto parts suppliers such as Bosch, Continental, Delphi, etc. for engine research and development, but they have been following, how to talk about surpassing, so China's auto industry has always been behind the auto industry in Europe and the United States Developed countries. Only by mastering the core engine technology can we gain a firm foothold in the market. Great Wall Motors understands this.

In order to break the passive situation where technology is controlled by others, in May 2000, Great Wall Motor Co., Ltd. established Baoding Great Wall Internal Combustion Engine Manufacturing Co., Ltd., the predecessor of Honeycomb Power. Since 2018, Great Wall Motor's parts and components business has achieved independent operations. This includes Honeycomb Yichuang, whose business covers power systems, traditional systems, electric drive systems and intelligent steering systems. In September 2019, Honeycomb Yichuang went abroad to make its debut at the Frankfurt Auto Show, which marked that Great Wall Motor's core technology went overseas.

Through years of development and technology accumulation, Great Wall Motors Honeycomb Power has successively broken through the Miller cycle, 350bar high-pressure injection, second-generation CVVL (Continuously Variable Valve Lift), thermal management technology, gasoline engine particle traps, and many other frontiers and even China Unique core technology in the brand. Completed the 4G15, 4B15, 4C20, 4N20, 6Z30 and 4D20/24 series of engine product layouts. It has realized the coverage from 1.5L-3.0L displacement range, setting a new industry benchmark for Chinese brands.

In the past 21 years, Great Wall Motors has not only achieved a leap in scale in the field of automotive power, but also expanded and climbed the field of power technology. Facing the "turbo lag" problem of traditional turbocharged engines, Great Wall Motors has adopted a multi-pronged approach such as VGT supercharger, cylinder head integrated exhaust manifold and water-cooled intercooler integrated intake manifold to greatly reduce the lag , So that the turbocharged engine can be as sensitive and linear as a naturally aspirated engine.

Compared with the traditional supercharger, Great Wall Motor's VGT supercharger improves the low-speed responsiveness and low-speed torque of the engine by 30%, and can reduce fuel consumption by 0.5% under the same circumstances. By integrating the exhaust manifold into the cylinder head, the lightweight design is realized, while the warm-up time of the cold car is greatly shortened, the fuel consumption is reduced, the turbo lag can be alleviated, and the engine power can be improved. The water-cooled intercooler integrates the intake manifold design. The intake manifold is integrated into the water-cooled intercooler, which not only effectively reduces the pressure loss of the supercharged air, but also makes it easier to ensure the intake temperature and allow the compressed air to enter the cylinder faster , To alleviate "turbo lag", improve the output characteristics of the engine, and enhance the acceleration capability of the vehicle.

Improving power and reducing fuel consumption are the eternal theme of the development of engine technology, and it is also the continuous pursuit of Great Wall Motors to strengthen its core technology. More precise control of the engine has become one of the main technical development directions in the engine field. Among them, the continuously variable valve lift technology is a cutting-edge technology for precise control of the engine valve train, and it is only in the hands of a handful of foreign auto brands. The well-known Honda Earth Dream engine and Volkswagen EA888 use only segmented variable valve lift. Great Wall Motors took the lead in breaking through the technical barriers of variable valve lift, achieved continuous variable, and has developed to the second-generation CVVL technology. Become the first and only automobile company in China to achieve breakthroughs in continuous variable valve lift technology.

The 10 millionth engine of Great Wall Motor's Honeycomb Power rolled off the assembly line, the 4B15C 1.5T in-cylinder direct injection gasoline engine independently developed by Great Wall Motor, is equipped with the aforementioned engine cutting-edge technologies. As a new generation power train of Great Wall Motors. This engine has been installed on Haval Chitu and other models. The maximum output power of 135kW and the maximum torque of 275Nm are at the forefront of the industry in terms of combustion efficiency, power output level and emission level. Fully autonomous power has become the core competitiveness of Great Wall Motors.
