2022 will be rated as the "first year" of the full blossoming of domestic passenger car electrification, and I believe that no one will raise objections. At present, almost all mainstream Chinese brands have launched their own series parallel hybrid system, more direct power response, more smooth and quiet driving experience, but with lower fuel consumption performance, in a sense, the series parallel hybrid system to achieve a reduction in the dimension of the fuel single-action system, a passenger car "de-fueling" movement has also been fully blown.
Great Wall Motor, as the head enterprise of domestic vehicle manufacturing, naturally follows the trend, very early launched the self-developed lemon hybrid DHT system, and now with the time has come, it has gradually come to the stage of batch loading, as a high-end power has been successively installed on its major brand models. Among them, after the Haval brand launched the DHT version of Haval Red Rabbit and Haval H6S, Haval Divine Beast also ushered in the DHT version and will be listed soon.
The era of hybridization is coming, and lemon DHT has many advantages
The engine, gearbox, chassis three major pieces, is the focus of many people to judge a car "good or bad", in which, the powertrain composed of engine and gearbox, directly accounted for two things, the importance is self-evident.
In the minds of many people, the reason why independent brands have not been able to compete with the joint venture brand for product strength, the powertrain lags behind the joint venture brand is a very big reason, which involves many factors, which may be the general technical level of the engine itself, the lack of competitiveness of power and fuel economy, or the lack of experience in the manufacture and adjustment of the gearbox and the entire transmission system.
However, the emergence of DHT hybrid technology can be said to have solved all the above problems almost perfectly, and behind it is not only the dare of major brands to try and break through, but also the accumulation of Chinese brands after years of technical accumulation.
With the successive launch of the hybrid technology of major independent brands, for the entire Chinese brand, whether it is its own market breakthrough or the erection of its own technology brand, it has also ushered in a best era.
Haval has always been its most important sub-brand for Great Wall Motors, and it is also the sub-brand with the largest sales scale, and the batch introduction of DHT hybrid on the Haval brand means that Great Wall is ready for large-scale "power-on".
From the perspective of the layout of the technology platform, great wall lemon hybrid compared to other independent brands, in addition to the launch time is relatively early, there is a key advantage is that the great wall for the different model market positioning, targeted launch of different DHT products, can better correspond to different markets.
Among them, the low-end model uses a 1.5-liter Atkinson cycle four-cylinder hybrid special engine as the core of the DHT system, the mid-range model uses the DHT system upgraded to a higher power 1.5T Miller cycle hybrid special engine, and the high-end model uses a 2.0T Miller cycle engine, and the power of the light engine body reaches 160kW.
From the technical principle, another feature of the Great Wall Lemon Hybrid DHT is that it adopts a two-speed design, which has one more gear than the current mainstream Japanese hybrid system, on the one hand, it can further improve the torque output, on the other hand, after the engine is involved in the drive, it can be in the efficient working range in more time, and the energy consumption of the whole vehicle is lower.
Compared with other DHT systems with more gears, the two-stop DHT system of great wall lemon hybrid better balances size, weight and economic cost, which belongs to the DHT technology with better comprehensive strength and market-oriented advantages.
DHT blessing, how does the "electricity" on the H6S perform?
H6 as Haval's sales responsibility, the first with DHT hybrid technology is the H6 family's first coupe SUV H6S, Great Wall tries to make the H6S more playable through the blessing of DHT.
In terms of power specifications, H6S uses DHT hybrid based on 1.5T engine, the total power of the system reaches 170kW, the total torque is 530Nm, the acceleration time of 0-60km/h is only 3.7 seconds, the fuel consumption of 100km is only 4.9L, and the comprehensive endurance is more than 1000km.
In the working mode, this H6S DHT can achieve pure electricity, series, parallel and energy recovery including a variety of working modes, in the low power request starting and battery high SOC and other working conditions, the vehicle can be driven by the drive motor vehicle, at this time the engine is in a shutdown state.
When driving in urban areas, when the battery SOC is low, the engine will start to work in series mode, the engine acts as a generator to generate electricity, the vehicle is driven by the drive motor, and the excess power can also be used to charge the battery.
In the medium high speed and high-speed steady-state driving, the system starts the parallel mode, the engine and the drive motor jointly drive the vehicle, the generator can be generated or driven according to different working conditions, the engine can be switched in two gears according to the different speeds, to achieve the best working point and system efficiency.
In actual experience, the overall operation quality of this DHT system created on H6S is very good, although it has two gears that need to be switched, but the system cannot experience power interruption when switching through methods such as driving motor to make up for twisting and regulating speed, and it is difficult to experience setbacks.
Write at the end:
The hybrid technology battlefield is a contest of cards, some people first grabbed a big king, feel that they are very good, but it is difficult to say whether they can continue to catch big names in the follow-up.
At present, Great Wall Motors is undoubtedly the first person to finish the card, which provides a good opportunity for Great Wall Motors to plan its own playing style combination in advance. At present, the Great Wall has not only comprehensively covered HEV technology, but also carried out a multi-dimensional layout in PHEV technology.
But this is also a very test of the Great Wall's playing methods, brands, models of so many Great Wall, how to better arrange and combine, to achieve full coverage of hybrid technology, but also have a certain price advantage, let us wait and see.
