On November 2, the "China Heart" 2020 top ten engines selection results were freshly released. Changan Automobile’s Blue Whale NE 1.5T high-pressure direct-injection engine, after undergoing many tests and rigorous selections, overwhelmed many competitors, and finally won the title of “China Heart’s Top Ten Engines of 2020”.
"China Heart" annual ten best engine selection was founded in 2006, it is the most influential automotive selection activity in China, and its judges are mainly composed of national automotive engineering experts, scholars from well-known universities and national key laboratories, and domestic engine related fields Leaded by experts and scholars. Together with "Ward's Top Ten Engines" and "International Engine of the Year", it is also called the selection of the world's three major engines. At present, Changan Automobile has been awarded the top ten engine awards with 4 engines for 4 consecutive years, demonstrating its outstanding quality.
Excellent quality gives users the most intuitive experience
When people evaluate a car, the engine performance must be one of the most important content. The performance of an engine in terms of power, fuel consumption, and quietness is not only directly linked to the performance of the engine, but also directly affects the consumer's car experience and even the final purchase decision. The Blue Whale NE 1.5T high-pressure direct injection engine mounted on Changan UNI-T participating vehicles was built by Changan Automobile in cooperation with top suppliers such as Bosch, Schaeffler, Valeo, Shell, etc. "The three major characteristics not only significantly improve the power performance, but also take into account energy conservation and environmental protection, and meet the national 6b emission regulations.
Blue Whale NE1.5T high-pressure direct injection engine has a rated power of 132kW and a maximum torque of 300N·m. It is matched with a seven-speed wet dual-clutch transmission. The maximum torque output of 300N·m can be achieved when the engine speed is as low as 1250 revolutions (rpm). Hysteresis is reduced to the point where it is not perceived by the driver. In terms of data, the Blue Whale NE1.5T high-pressure direct-injection engine is not only superior to its peers, but even comparable to the 3.0L naturally aspirated engine. Such a strong power performance is naturally inseparable from the adoption of various advanced technologies.
Blue Whale NE1.5T high-pressure direct injection engine adopts a rare dual-exit integrated exhaust manifold (IEM) of the same level, which effectively reduces engine exhaust interference, enhances exhaust pulse, and improves power output; dual-scroll tube electronically controlled turbocharging , Effectively reduce turbo lag; Smart Phaser, the intelligent cam phase modulation system, can achieve faster adjustment response speed. Compared with traditional VVT products, the phase response speed is increased by 175%, the power response is faster, and the driver is lighter and more powerful. Driving experience. In terms of fuel consumption, with the help of the original "AGILE Agile" air-guided high-efficiency ultra-clean combustion system, the 350bar high-pressure atomized fuel and the airflow formed by the high tumble air passage are perfectly matched to achieve uniform mixing in the cylinder and rapid combustion; at the same time It adopts a rare dual-outlet integrated exhaust manifold (IEM) of the same level, and its surrounding cooling water jacket effectively improves the warm-up speed, while reducing the exhaust temperature after the heat engine, improving the combustion efficiency, and accurately regulating the intelligence of the oil supply The lubrication system achieves ultra-low friction and effectively reduces user fuel consumption. The data shows that the UNI-T Ministry of Industry and Information Technology equipped with the Blue Whale NE1.5T high-pressure direct injection engine has a combined fuel consumption of as low as 6.3L per 100 kilometers, allowing both strong power and economic performance.
Not only that, the Blue Whale NE1.5T high-pressure direct injection engine also integrates world-class NVH control technology, which effectively reduces the resonance, knock, roar and other possible phenomena of the entire power transmission system and the vehicle. The sound pressure level of the whole machine at 1 meter idling speed is as low as 58.9dB(A), realizing the deep-sea level silence in the UNI-T cockpit; and when the power bursts, the dynamic, pure and bright acceleration sound can also ignite the driver's driving passion .
Accumulated R&D to give strong power to kinetic energy
Blue Whale Power, as an important part of Changan Automobile’s new energy strategy "Shangri-La Plan", as early as November 2016, took advantage of the launch of its flagship model CS95, and began to spread with the Blue Whale 2.0T. , And formed a deep brand among consumers; In June 2019, Blue Whale Power was officially released again as a family. The Blue Whale NE power platform was built by Changan Automobile's China, UK and global R&D teams under the "Jet Lag" uninterrupted R&D model, which lasted 4 years. It is the first Chinese brand based on the leading modular top-level design, facing the next generation of emissions , Fuel consumption standardNew modular engine development platform. The
Blue Whale NE power platform integrates a number of advanced technologies and is designed to be compatible with 1.0-1.8L displacement. The generalization rate is as high as 98%, and the production line automation rate and intelligence rate have reached the international advanced level. While meeting the national 6b emission regulations, the whole series are compatible with 48V, HEV, PHEV, and REEV designs, fully embracing the electrification era. It not only fills the gaps in the field of domestic automobile platform development, but also promotes Changan Automobile to officially enter the "power 3.0 era."
In order to ensure the reliability of Blue Whale NE power platform products, Changan’s Chongqing Headquarters R&D Center and its UK center simultaneously conducted test development and reliability verification, completing more than 300 system-level and more than 2,000 component-level test verifications. At the same time, more than 30 additional verification tests were added for the new technologies and new processes applied. Each Blue Whale NE engine has to undergo more than 25,000 hours of bench reliability verification, and the accumulated road mileage of the entire vehicle is more than 1.4 million kilometers to ensure the high quality of the Blue Whale NE engine.
In addition, the Blue Whale NE engine production line also guarantees stable production and realizes full-process visual production through an efficient and highly intelligent flexible production line mode. An automated production line composed of world-class advanced machine tool manufacturing company equipment + truss manipulator + robot + automatic logistics is used to effectively ensure the quality of the whole machine and the requirements of assembly consistency. Coupled with the production line QG&EP&MP quality control standards, and the construction of a three-dimensional quality prevention and control network, the Blue Whale NE engine production line also realizes the detection, monitoring, error prevention, and traceability of the production process, thus ensuring the performance, life and quality of the engine. Important guarantee function.
Currently, the Blue Whale family continues to exert strength and has continuously won excellent results. In September, the monthly sales of the Blue Whale family exceeded 90,000 units. Among them, the UNI-T equipped with the Blue Whale NE 1.5T high-pressure direct-injection engine achieved a single monthly sales of 10,601 bicycles, achieving a record of breaking 10,000 sales for three consecutive months. At the same time, the "Blue Whale Double Heroes" also performed well. With the help of the CS55PLUS Blue Whale Edition, the CS55 series sold 12,951 vehicles in September, an increase of 28.8% month-on-month and 50% year-on-year. The Ruicheng CC Blue Whale Edition also achieved 3,516 sales in September, an increase of 113.9% year-on-year. In October, the cumulative sales of the Blue Whale family are expected to exceed 100,000+.
