When it comes to hybrid vehicles, many people will think of toyota and Honda hybrid systems, but in fact, the power of independent brands in the field of hybridization in the past two years is also amazing, such as the Great Wall's "Lemon Hybrid DHT" system, which can not only make the vehicle have a very low fuel consumption level, but also be more efficient and smooth in power transmission. So is lemon-blendED DHT really as powerful as the legend goes? Coincidentally, today we found Haval's 3 new models equipped with lemon-mixed winter melon DHT - Divine Beast, Red Rabbit and H6S, to learn the true skills of DHT.
In fact, "Lemon Hybrid DHT" is the general term for haval hybrid system, it has two power forms and three sets of powertrains, in order to correspond to the use of different levels of models, to meet the user's diversified choices. For example, Haval Chitu Lemon Hybrid DHT, it is equipped with a 1.5L naturally aspirated hybrid engine + DHT powertrain, the comprehensive maximum power is 140kW, the comprehensive maximum torque reaches 370N·m, the acceleration time of 0~60km/h is only 3.9s, and the comprehensive fuel consumption of 100 km is only 4.7L, and the cruising range of a tank of fuel exceeds 1000km. Both the power response and the fuel consumption level far exceed those of traditional combustion engines.
As a high-end model of the Haval series, the Mythical Beast Lemon Hybrid DHT uses a higher-order 1.5T+DHT+HEV powertrain, using the Miller cycle 1.5T engine with a maximum net power of 113 kW, a maximum torque of 230 N·m, and a thermal efficiency of 38%. After the motor is added, the total power of the system is 179 kW, and the maximum torque reaches a staggering 550 N·m! The acceleration time from 0 to 100 km/h is 7.7 s, and the comprehensive fuel consumption per 100 km is only 5.5 L.
Let's take a look at the performance of the new member of the Haval H6 family, H6S, which is positioned as a cross-border model of the new era tide running weapon, not only in the appearance of the shape of more dynamic cool, thanks to the excellent powertrain of lemon hybrid, Haval H6S maximum power of 179 kW, maximum torque of 530N·m, under the support of the motor, the hybrid system acceleration of the push back feeling is stronger, 0 ~ 60km / h acceleration of only 3.7 seconds, to the urban use of the scene as an example, 100 km fuel consumption as low as 4.9L.
Obviously, as an "all-round" hybrid system, Lemon Hybrid DHT can realize various working modes such as EV driving, series drive, engine direct drive, energy recovery, idle shutdown and other working modes by virtue of its self-developed dual-motor HEV architecture, and achieve a perfect balance between power and fuel consumption in various driving scenarios through intelligent switching of the control system. So compared with the traditional giants toyota and Honda in the field of hybrid, how does the lemon hybrid DHT perform?
Although the Toyota THS and Honda i-MMD hybrid systems seem very mature, they are not perfect in reality. For example, the Toyota THS hybrid system is based on the optimal engine energy consumption as the infrastructure design logic, designed to make the engine fuel-efficient, so it abandons the dynamics and is suitable for urban commuting, rather than the new hybrid logic of full-speed in the whole area. Although the Honda i-MMD hybrid system achieves the basic full speed and full domain, ensuring fuel economy, but the cut is strong, the feeding capacity in series is limited, because it is a single gear, so the medium and high speed is limited by the upper limit of the system, and the power is weak.
In contrast, the overall idea of lemon hybrid DHT is more perfect. The two-speed setting of lemon hybrid DHT allows the engine to intervene in the drive earlier, making up for the shortcomings of Honda's poor power performance in the middle and high-speed sections, while optimizing and improving the NVH and smoothness, under the premise of ensuring low fuel consumption, while ensuring the power performance of 0 ~ 60km / h, as a hybrid system in the new era, compared with the "two fields" can be said to be "dimensionality reduction strike".
In addition, Lemon Hybrid DHT also has a set of energy control strategies with completely independent intellectual property rights. This includes no-interruption shifting, intelligent clutch control, motor torque compensation matching, and IGBT junction temperature estimation. To put it bluntly, the energy change is almost impossible to feel during the switch of oil and electricity mode, and the passengers in the car will not feel any discomfort.
In my opinion, hybrid technology can be said to be the most adaptable power system to the current development trend. Because it not only has lower fuel consumption than the traditional internal combustion engine, but also with the blessing of the electric motor, the power has increased significantly. In addition, hybrid models do not cause "mileage anxiety" to car owners like pure electric models. Therefore, vigorously developing hybrid technology has also become the consensus of major car companies. Although the achievements of "Liangtian" in hybrid technology are very prominent, with the continuous rise of our own brands, especially companies like Haval Automobile can collapse their hearts to develop technology, which is definitely a matter of pride. The lemon hybrid DHT hybrid technology is the result of Haval Automobile's continuous innovation, which not only surpasses the former "predecessor" from the technical level and launches a strong impact on the joint venture hybrid model, but also presses the acceleration key of the layout of Haval brand new energy products, providing a strong thrust for the realization of the 2025 strategic goal.
