Industry first 33911, the black technology behind the numbers
Japanese hybrid has been fighting in the market for a long time, and a few years ago it was almost talking about hybrid japanese technology, but since last year, more and more independent brand hybrid technology has emerged, which has brought a very big breakthrough to the field of hybrid. As the first hybrid technology in 2022, the "Star Core Power ET-i Full Engine Super Hybrid" industry's first "3 Engine 3 Gear 9 Mode 11 Speed" contains a lot of black technology.
"3 engines" refers to the intelligent combination of internal combustion engine and dual drive motor under this power architecture. The "1 Engine" is a 1.5T hybrid engine that produces 115 kW of power and a maximum torque of 230 N.m. In addition to this 1.5T engine, Xingtu's hybrid also includes two special engines, 1.5TGDI and 2.0TGDI, which are more efficient and have better power performance, suitable for models with higher power requirements, and a rich powertrain will further enrich consumer choices.
The other "2 engines" are two motors integrated in the DHT cabinet that are 55kW /160N.m and 70kW /155N .m, respectively. Compared with the existing hybrid technology, these two motors can participate in the drive, which will undoubtedly bring more powerful performance, of course, the system will judge whether to drive with one or two motors according to the power demand, and the efficiency will be higher. At the same time, the ultra-high density I-PIN flat wire motor technology makes the motor smaller and the high efficiency range is moved forward, so the specific power of the two motors is as high as 6.0kW/kg, which is simply that the performance far exceeds other hybrid technologies, which is very suitable for consumers who have high requirements for power.
The low fuel consumption brought by high transfer efficiency has always been the advantage of Japanese hybrid products, and the star core power ET-i full engine supermix combines two-way processing of tooth surface, low tow clutch, efficient oil pump, main oil pressure following strategy and other technical measures, making the maximum transmission efficiency of the system exceed 97.6%, maintaining the same level as Japanese products.
Not only that, Star Core Power's original FIO fixed-point injection oil cooling technology, in the motor operation using multi-point uniform injection + rotor oil oil cooling technology, this technology can effectively control the motor temperature rise, the final effect is to make the practical life of the motor reach 1.5 times the industry average, there will be no consumer concerns about the high cost of replacing the motor caused by the problem.
3 gears" refers to the "Star Core Power ET-i Full Engine Super Hybrid" power architecture with the most 3 physical gears in the existing hybrid technology, more gears also determine that the system can cope with more and more complex car use scenarios, and the efficiency is also higher, the strong power and excellent fuel economy required by consumers can be well balanced.
"9 mode" is the abbreviation of the 9 working modes unique to the "Star Core Power ET-i Full Engine Supermix" system. Including single motor pure electric, dual motor pure electric, engine direct drive, parallel drive, parking charging, driving charging and other 9 driving modes. Under the control of the intelligent system, it can be freely switched according to different driving scenarios such as urban roads and highway sections, and match different road conditions with the most suitable and efficient mode. More driving modes make the model equipped with "Star Core Power ET-i Full Engine Super Hybrid" not perform poorly at high speed and other road conditions like other hybrid products, and the range of consumer cars will undoubtedly be wider.
"9 modes" is followed by "11 speeds", 11 gear combinations selected by Xingtu Auto engineers in tens of thousands of measured data can cover all car use scenarios, covering almost all driving scenarios that users may encounter, including urban commuting, long-distance travel, and extreme road conditions, taking into account surging power and ultra-low fuel consumption.
At all stages of driving, the "Star Core PowerED ET-i All-Engine Supermix" maintains optimal efficiency. In the initial stage of the most fuel consumption, the "Star Core Power ET-i Full Engine Supermix" system adopts dual motor pure electric drive, which avoids the high energy consumption at the start, and can generate strong torque with the dual motor drive, making the start more rapid and smooth. In the low- and medium-speed stages, there is no need for large torque, and the system will automatically select one of the single motors to drive, and the fuel consumption is lower than that of the start-up stage. On other hybrid technologies with fuel consumption, low power advantages on the elevated or ring highway, the 3 engines will drive together and output an astonishing torque comparable to the 510N·m of a six-cylinder gasoline engine.
4 core value points, fish and bear paws are all required
The biggest significance of hybrid technology at present is to provide a more convenient, more comfortable and more relaxed car life. The "Star Core Power ET-i Full Engine Super Hybrid" power architecture has "3 engine 3 gears, 9 modes and 11 speeds" and integrates the four core values of "strong power, ultra smooth, long endurance and extreme fuel saving".
The core purpose of hybrid technology is to save energy, but often hybrid models will sacrifice power performance for energy saving. The "Star Core Power ET-i Full Engine Super Hybrid" technology, the total power of the two-wheel drive version reaches 240kW, the maximum wheel torque exceeds 4000N.m, the acceleration of 100 kilometers is less than 7s, the total power of the four-wheel drive version is 338kW, the maximum wheel side torque exceeds 6300N.m, and the acceleration of 100 kilometers into the 4s level, especially in the power reserve and acceleration ability in the high-speed range. At the same time, with the blessing of TSD dual-shaft drive technology, the power interruption and loss during the shift process are avoided, and the driving smoothness feels very smooth, and the experience is comparable to pure electric models.
Returning to the hybrid model "long endurance" and "extremely fuel-efficient" housekeeping skills, the "Star Core Power ET-i Full Engine Super Hybrid" technology performance is also excellent, more reliable and more stable. The intelligent hybrid control system adopted by the STAR Core Power ET-i Full Engine Supermix technology allows the three engines to always work in their optimal performance range and ensure the lowest energy consumption. There is also a full-road adaptive power mode, the power control system and the navigation system dual-core interconnection, in advance to identify the road conditions and intelligently achieve the optimal power scheme; at the same time, the CRBS energy recovery system is used to further recover kinetic energy and save fuel consumption.
These high-tech applications allow Xingtu Automobile to achieve ultra-long endurance and extremely low fuel consumption without the need for large and heavy fuel tanks and batteries. Models equipped with "Star Core PowerED ET-i Full Engine Supermix" technology can achieve a comprehensive fuel consumption of 1L/100km, and even the fuel consumption of feed can reach 4.8L/100km. On the upcoming sale of the "Star Core Power ET-i Full Engine Super Hybrid" technology first model - StarWay Wind Chasing ET-i, the standard version can reach a pure electric mileage of 105km, a comprehensive driving range of more than 1000km, and the user's daily commute pure electric endurance is more than enough.
