On January 7, 2022, The Star Core Power ET-i Full Engine Supermix was officially released in the form of a webcast, which is a plug-in hybrid system. The whole system consists of a plug-in hybrid system composed of a 1.5T engine + electric motor, of which the maximum power of the engine is 147 horsepower, and the fuel consumption declared by the Ministry of Industry and Information Technology is 1.0L/100km. According to the official introduction, the star core power ET-i full engine super hybrid comes with 3 engine 3 gears, 9 modes and 11-speed bonus, integrating DHT, full-scene drive, high transmission efficiency, intelligent travel, intelligent electronic control drive, super endurance six major technologies, and the whole scene is applicable.
In the "Star Core Power ET-i Full Engine Super Hybrid" power architecture announced this time, the fuel engine is combined with a full-featured DHT transmission, which realizes the core advantages of the industry-leading "3 Engine, 3 Gear, 9 Modes and 11 Speed" technology. Combined with the intelligent control system and the power architecture composed of high-performance battery packs, its performance has realized the leap of China's hybrid technology from the 1.0 stage to the 2.0 stage.
Among them, "3 engines" refers to the intelligent combination of internal combustion engine and dual drive motor under the power architecture. Among them, the "1 engine" is a 1.5T hybrid special engine, which can produce 115kW of power and a maximum torque of 230N·m, in addition to this 1.5T engine, Xingtu's hybrid special engine also includes 1.5TGDI and 2.0TGDI, which are suitable for models with higher power requirements.
The other "2 engines" are two motors integrated in the DHT cabinet that are 55kW /160N.m and 70kW /155N .m respectively. Among them, the ultra-high density I-PIN flat wire motor technology makes the number of coil turns under the same volume more, realizes the motor volume is smaller, the efficient range is moved forward, the torque / weight ratio is higher than the predetermined goal, combined with the tooth surface two-way processing, low towing clutch, high efficiency oil pump, main oil pressure following strategy and other technical measures, so that the maximum transmission efficiency of the system exceeds 97.6%, reaching the same level of Japanese products. The FIO fixed-point injection oil cooling technology originally created by Star Core Power adopts multi-point uniform injection + rotor oil-oil cooling technology when the motor is running, which can effectively control the temperature rise of the motor.
"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, and more gears also determine that the system can cope with more working conditions, higher efficiency, and can optimally balance power and fuel consumption.
"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, they can freely switch according to different driving scenarios, and match different road conditions with the most suitable and efficient mode. More driving modes naturally have a wider range of adaptation, which is also a strong generation difference advantage of the second generation hybrid system compared with the first generation of hybrid systems.
"3 engines, 3 gears, 9 modes and 11 speeds" Even through simple permutations and combinations, we can calculate dozens of working modes. The "11 speed" here refers to the comprehensive analysis of tens of thousands of data measured by Xingtu Auto engineers, from which 11 gear combinations can cover all car scenes, covering almost all driving scenarios that users may encounter, including urban commuting/long-distance travel/extreme road conditions, but also achieving a perfect balance between power and energy consumption. "9 mode 11 speed" makes the fuel saving rate of the "Star Core Power ET-i Full Engine Super Hybrid" system is also the world's leading level, and the fuel saving rate of the low power mode > 50%. The fuel saving rate of urban working conditions >55%, and the fuel saving rate of high-speed working conditions > 35%.
In terms of power performance, the "Star Core Power ET-i Full Engine Supermix" technology, the total power of the two-wheel drive version reaches 240kW, the maximum wheel side torque exceeds 4000N·m, the acceleration of 100 km is less than 7s, the total power of the four-wheel drive version is 338 kW, the maximum wheel side torque exceeds 6300 N·m, and the 100 km acceleration enters the 4s level. The comprehensive fuel consumption can reach 1L/100km, and the feeder fuel consumption is 4.8L/100km.
