September 9, long comfortable moving into the Chinese BARI PLUS aerodynamics – acoustic wind tunnel laboratory, in the form of live, public participation in industry first third-party certification testing low-drag models final Yi PLUS to move the drag coefficient 0.27Cd, aerodynamic drag 411.86N (120km / h) of outstanding achievements by China BARI “low drag car” certification, the same level of performance to the leading domestic level fuel cars.
At present the drag coefficient of the industry mainstream fuel cars roughly between 0.28-0.4Cd, the following general 0.3Cd even excellent results.
is to determine the aerodynamic car automobile design, wind noise performance, fuel economy, high speed stability the key index, which is the size of the car drag coefficient is an important indicator of evaluating aerodynamic performance of the car. Under certain conditions, the lower the drag coefficient, the car’s design will be better, better fuel economy, wind noise is also lower.
The move PLUS Plaza won the Chinese BARI “low drag car” certification and Changan Automobile stringent behind repairer system and user-centric concept cars are inseparable. As a systematic optimization of automobile engineering, automotive aerodynamics extremely important issue to optimize the quality of work directly related to the aerodynamic performance of a car, also a direct impact on vehicle design and fuel consumption, etc. . In order to create a beautiful shape, better fuel performance models, long comfortable moving PLUS of CFD (computational fluid dynamics) technical team through a series of scientific rigor, reliability analysis and demonstration, we have done including front, front bumper, key parts of the entire machine cover 13, the front windshield, a pillar, the vehicle body side portion, roof, mirrors, rear window, the rear, the trunk, and the rear bumper of the vehicle wheel cavities such key parameters 22 car optimize processes, fully optimized aerodynamic performance vehicle designed for the user to create this explosion models – Yat move PLUS.
Yi movable PLUS streamlined fashion using dynamic aesthetic design, to simplify the through front face of the design family lineage. Side waist simple and clean, sporty, multi-line shape tailCreating a strong sense of hierarchy, so that every movement of DNA into the body of the vehicle, passing from the front to the rear, just to bring you all have a rhythm of life like the new generation handsome sporty appearance.
facelift front windshield wipers wipers, wiper brush is smaller, is not only easier to install, use less noise, but also brings less wind resistance, by contrast, reduced wind 0.002Cd resistance.
nacelle water cooling type cooling device, the appropriate front grille inlet opening boundary, to ensure low drag aerodynamics needs, water-cooled type cooling device nacelle embodiment, nacelle solve the thermal management needs, to avoid overheating the engine compartment, the engine achieved while reducing the temperature, reducing the wind resistance requirements.
before bottom lip arc optimized to meet the approach angle at the same time, so that the arc is more full front lip, into the car the bottom stream more fitting.
A pillar garnish installation, trim the groove at the junction between the A-pillar and the front windshield can effectively reduce wind resistance and wind noise value of the area, due to the high cost of the parts, now only the same level Yi and a few models equipped with movable PLUS.
The roof laser welding process, laser welding Yi movable PLUS technology, compared to the more common spot under pressure strong, non-traditional design and the inherent flow tank, the cap over the smooth side panels, roof shape flatter, better sealing, and to further reduce wind resistance. Not only safe, comfortable and beautiful, but also help reduce wind noise and fuel consumption.
using shark fin roof antenna, from the bionic design technology, and the use of aerodynamics , effectively eliminating the traditional airflow noise rod antenna, making travel more quiet.
After design optimization of the wind, the wind design that is more inclined than the conventional sedan smoother the rear shorten and increase the upturned tail design ducklings, let Yat move more movement on the PLUS dynamic modeling, and more conducive to direct airflow, reduce wind resistance.
After the bumper on both sides of distinct characteristic line
, to guide the direction of flow separation tail; body side while a more pronounced contours reduce wind resistance.
long comfortable moving PLUS openly broadcast industry’s first independent third-party certification testing and low drag models achieved excellent final low drag performance is the strength of their products, especially the design is very confident; sedan as national sales leader, Yi is not only moving PLUS explosion models, but also a classic car, and only stand the “tempered” in products, are likely to become a classic. Hot Yat move PLUS, it is derived from Changan Automobile user-centric, the pursuit of quality cars concept of tireless. With leapfrog product quality and strength, PLUS Yat move will further continue selling momentum, gain a firm foothold in the joint venture brands are the compact car market.
