With the proposal of my country's "dual carbon" goal, a new wave of technological revolution in the automobile industry has also arrived. This is another severe challenge in the development process of Chinese automobile companies. In view of the sustainable development vision of industrial energy conservation and emission reduction, how to break the technical barriers of joint venture monopoly and create more efficient and fuel-saving models is a new topic that Chinese automobile brands have to face.
Powerful on the hybrid track, using technology to break through to achieve zero-stress car use for users
An excellent product should be able to promote a new trend in the market. As a leading brand in China's automobile industry, the Haval brand has relied on the technology accumulation of Great Wall Motors over the years to take the lead in achieving technological breakthroughs for joint ventures in the hybrid field, and recently launched a new flagship hybrid model: Haval The mythical beast hybrid DHT. The new car enriches the hybrid product matrix of the Haval brand with its leading hybrid architecture, and provides users with a new choice that eliminates the stress of using a car with its leading hybrid technology.
my country's current energy structure is still dominated by thermal power, which also makes it difficult for pure electric vehicles to achieve true carbon neutrality during use. Moreover, the energy replenishment efficiency of pure electric vehicles, which often takes half an hour, also prohibits many users. However, other new energy solutions such as hydrogen energy and solar energy have not yet reached the stage of commercial mass production. Therefore, the hybrid architecture has become the optimal solution that balances performance and energy consumption.
In addition, under the pressure of continuously rising oil prices, today's consumers are also more picky about the fuel consumption of vehicles. The leading hybrid technology architecture of Haval Divine Beast hybrid DHT combines the comprehensive advantages of fuel vehicles with strong high-speed power, convenient refueling, and low-speed and more energy-saving electric vehicles. With efficient operation in the full speed range, it has opened up the joint venture hybrid market. The technical defense line shows consumers a local solution for zero-stress car use.
1.5T high-end hybrid dedicated engine supports hybrid track performance and breaks the lap
Traditional hybrid models are restricted by many factors such as cost and power structure, and are often unable to achieve both fuel economy and power performance. of both. Therefore, most hybrid models in the past often only used fuel economy as a selling point, and lacked user perception in terms of driving experience.
Based on users’ car needs in all scenarios, the Haval Divine Beast Hybrid DHT is equipped with a hybrid-specific 1.5T engine that has been selected for China’s Top Ten Engine Awards in 2021. It represents the technology trend and manufacturing level of high-level engine products in the Chinese market. This engine adopts a high compression ratio of 11.8, a high tumble intake port, a deep Miller cycle, and 980°C VGT supercharger leading technology. The thermal efficiency of the entire machine is better, the turbine response is faster, and the power is more powerful. .
At the same time, its four-cylinder structure engine runs smoother and quieter than many hybrid systems that use three-cylinder engines to reduce costs. In terms of user experience, the most intuitive feeling is a stronger push-back feeling when accelerating, more powerful when climbing, and lower fuel consumption.
Two-speed direct drive + dual-motor fast switching Amazing strength of joint venture
Different from the single hybrid structure of single-speed direct drive and series hybrid of current mainstream joint venture hybrid models, Haval Divine Beast Hybrid DHT uses two-speed DHT The gearbox has two gears: power direct drive and economical direct drive. Whether facing high-speed cruising or car use scenarios that require rapid acceleration to overtake, it can make the most appropriate choice for users.
When the user's driving intention is conservative, the economical direct-drive gear gives priority to ensuring fuel consumption; when stronger power output is needed, the power direct-drive gear can use stronger power to produce a more powerful power output. Under urban conditions, the vehicle's overall system efficiency is 3% higher than that of single-gear series-parallel architecture models, and is 0.5% better than the power split architecture. Under high-speed climbing conditions, the vehicle's overall efficiency is higher than that of single-gear series-parallel architecture. Models with the same architecture increased by 8.5%, which is a clear advantage.
In addition, the new car also adopts a self-developed dual-motor hybrid topology architecture, which can realize EV driving, series drive, engine economical direct drive, engine power direct drive, parallel hybrid drive, and energy recovery mode through intelligent switching of the control system. The six driving modes include intelligent switching, which can adapt to a wider speed range and provide better overall performance than the joint-venture hybrid with a single structure.
Through the efficient matching of the engine, two-speed DHT gearbox, and dual-motor HEV structure, the Haval Divine Beast Hybrid DHT can always ensure the maximum efficiency of the power system in the full speed range and in all scenarios. During high-speed steady-state cruising, the system automatically switches to the economy gear for direct-drive vehicles, which is more fuel-efficient; when it is necessary to accelerate overtaking, the power gear for direct-drive vehicles is used for stronger acceleration performance, thus achieving both fuel-saving and Powerful technological breakthroughs in high-speed output. The total operating power of the
vehicle reaches 179kW, the comprehensive torque is 530N·m, it only takes 4 seconds to accelerate from 0-60km/h, 7.7 seconds to accelerate from 0 to 100 kilometers, and the overall efficiency exceeds 50%. According to the measured data of national standard working conditions, the WLTC standard fuel consumption of the vehicle is only 5.5L, and a tank of fuel can achieve a range of more than 1,000 kilometers, truly planning every trip for users with careful budget
