Tramway News: On January 7, Xingtu Automobile released the latest achievement in the field of hybrid technology - "Star Core Power ET-i Full Engine Super Hybrid" technology, through a powerful engine with a full-featured DHT transmission, to achieve the industry-leading "3 Engine 3 Gear 9 Mode 11 Speed" technology core advantages, the release of this technology also marks the release of EXEED Starway officially into the field of new energy hybrid.
The most noteworthy thing is that this technology is one of the key special projects of the "13th Five-Year Plan" National Key Research and Development Plan "New Energy Vehicles", during the entire technical attack period, the engineers of Xingtu Automobile have overcome many problems with complex system structure, engine control, transmission control, drive motor control and vehicle control, and created a new path of Hybrid Power in China with complete intellectual property rights.
"Star Core Power ET-i Full Engine Super Hybrid" technology will be "strong power, ultra smooth, long endurance, extremely fuel-saving" 4 core values at the same time, the current technology can achieve feed fuel consumption of 4.8L / 100km, truly "squeeze dry" every drop of oil. On the upcoming "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 driving range of 105km, and a comprehensive driving range of more than 1000km. Let users bring daily commuting without fuel, high-speed long-distance no worries about the car experience.
33911 is the core advantage of Xingtu Automobile's latest hybrid technology, specifically, "3 engines" refers to the intelligent combination of internal combustion engine and dual-drive motor under the power architecture; "3 gears" refers to the "Star Core Power ET-i Full Engine Supermix" power architecture has the most 3 physical gears in the existing hybrid technology; "9 modes" is the abbreviation of the 9 working modes unique to the system; "11 speed" is the comprehensive analysis of tens of thousands of measured data by The engineers of Xingtu Automobile. Among the dozens of operating modes of the system, 11 are selected to truly cover all combinations of gears in the parking lot.
With the blessing of two physical means of 3 engine and 3 gears, star core power ET-i full engine supermix has 9 driving modes including single motor pure electric, dual motor pure electric, engine direct drive, parallel drive, parking charging, and driving charging. 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.
With the above advantages, the system can actually achieve up to dozens of working modes, but Based on the actual needs of users, Xingtu Automobile selects 11 gear combinations that can cover all parking lot gears, covering almost all driving scenarios that users may encounter, including extreme road conditions for urban commuting and long-distance travel, but also achieving a perfect balance between power and energy consumption.
This "11 speed" can be said to be the essence of the best of the best through the accumulation and analysis of big data. For example, in the initial stage, this is the stage with the lowest thermal efficiency and the largest energy consumption of the internal combustion engine, so at this stage, the system is set up with a dual motor pure electric drive. It can not only maintain the economical energy consumption of the vehicle, but also change the inherent perception of the soft start of the hybrid model with the powerful torque generated by the industry's unique dual motor drive.
When high torque is not required at low to medium speeds, the system automatically selects one of the single motors to drive, making it consume less energy than the start-up phase.
On the elevated or ring highway, in order to meet the scenes such as accelerated overtaking in the middle and high-speed areas, the system's 3 engines drive the vehicle at the same time, which can output 510NM of torque comparable to a six-cylinder gasoline engine.
By the time of the smooth operation of the medium and high speed, the internal combustion engine has reached its optimal thermal efficiency range, and the system will allow the internal combustion engine to drive the vehicle directly.
"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%. It can not only meet the demand for power in consumer car scenes, but also implement the concept of fuel saving of hybrid vehicles to the extreme.
It can be said that the advent of star core power ET-i full-engine supermix also makes China's hybrid technology have the strength to surpass foreign advanced hybrid technology for the first time, which is a veritable national hybrid technology "black technology", and realizes the independent control of Key Core Technologies of Hybrid by Chinese car companies. The first model to apply this technology, "Starway Wind Chasing ET-i", is also about to be launched, allowing The hybrid technology of Starway Automobile to take root and blossom.
