The new third-generation Roewe RX5 is equipped with the GS61 engine for the first time
The third-generation 1.5T supercharged direct-injection engine GS61, which is used in SAIC Roewe's new roewe RX5, is about to unveil its mystery for the first time.
This engine, independently developed by SAIC, is the first product launched by SAIC's Zhengzhou engine plant, and is also the first engine product with the most new technologies used by SAIC. On the basis of inheriting the "Double Ten Best" powertrain gene, the "re-upgrade" of comprehensive improvement has been realized. What are the technical highlights of the GS61? The relevant person in charge of the Zhengzhou engine plant of SAIC Motor Group gave a detailed introduction.
GS61 1.5T adopts a new generation of SAIC Blue Core's power technology, continues the "Double Top Ten" powertrain gene, and achieves five major upgrades:
The first item: combustion optimization, so that the starting is more powerful
Engine output power, first of all depends on the gasoline combustion efficiency, engine output power, first of all depends on the gasoline combustion efficiency, SAIC Blue Core Power GS61 1.5T engine adopts a new generation of SGCS combustion system, with 350bar high-pressure fuel injection system and electronically controlled variable section turbocharger, bursting out 300 Nm maximum torque, achieving 188 horsepower maximum horsepower, is the class of 1.5T engine deserved leader.
The second item: gas exchange, so that travel more fuel-efficient
The degree of fusion between gasoline molecules and air directly affects fuel consumption! SAIC Blue Core GS61 engine through the application of low-pressure exhaust gas recirculation technology and other technologies, the new third-generation Roewe RX5 fuel consumption is only 6.0L/ 100km (NEDC), in terms of fuel economy so that consumers eat a "reassuring pill"
Of course, the GS61 has more to offer than just its powerful power and ultra-low fuel consumption.
The third item: thermal management, to make the operation more efficient
The addition of "black technology" makes the hot car not have to wait too long. THE SAIC LANXIN GS61 engine is equipped with technologies such as high and low temperature dual circulation cooling system, thermal management module/double thermostat and electronic water pump EWP, covering the thermal management needs of various driving scenarios. This not only significantly improves cold start emissions and warm-up rates, but also leads to better economy, killing two birds with one stone.
"Black technology" is not over!
The fourth item: reduce friction and make the operation more harmonious
40% of the domestic thermal efficiency is the "ceiling"? SAIC Blue Core GS61 engine is born to stand on the "ceiling". Through the combination of electronic water pumps, Fast VVTs, pendulum dual-mass flywheels, continuous variable oil pumps and water-cooled intercooling systems, low-tension timing transmission systems, and journal size optimization, friction reduction coatings, etc., friction losses are reduced by 21% compared to the previous generation, while the maximum thermal efficiency is increased to nearly 40%, and the efficient operation area of the entire power system is increased by 30% compared with the previous generation.
Driving requires not only speed and passion, but also enjoyment and tranquility.
Fifth item: NVH, make the ride more enjoyable
The engine is reduced by one decibel, and the acoustic cotton is one millimeter thinner. Saic Blue Core GS61 engine in the NVH optimization, the engineering team also made great efforts. Through the lightweight design of the body structure and crank linkage mechanism, as well as the application of acoustic wrapping in key parts such as timing system and fuel system, coupled with finer calibration optimization, idle sound power is internationally leading, which can bring an electric vehicle-like quiet experience to the interior.
The annual production capacity of the second phase of the project will reach 600,000 units after it is put into operation
As the largest engine manufacturing base of SAIC Motor In the future, saicid motor Zhengzhou engine plant phase II project will reach an annual production capacity of 600,000 units, which will meet more than 50% of the total national production capacity of SAIC passenger cars. And all use imported equipment, the main core processing equipment from Germany, Spain, Italy and China's world-class powertrain processing equipment manufacturers.
The assembly line workshop covers an area of 0.5 million square meters, including three modules: engine internal assembly line, engine external assembly line and hot test. The engine assembly line uses a fully automatic engine cold state tester to ensure that each engine achieves design performance before delivery.
The GS61 engine has 62 patented technologies, which apply a series of key technologies such as direct injection in the cylinder, 350 bar high-pressure fuel injection system, cylinder head separation and cooling, electronic water pump, variable section turbocharging, continuous variable displacement oil pump, water cooling and intercooling, low pressure exhaust gas recirculation, fast phase modulation VVT, variable valve lift and so on.
The wheelbase of 2765mm "Phoenix" shape is more eye-catching
In addition to the "strong heart" of SAIC Blue Core Power GS61, the new third-generation Roewe RX5 also has a maximum wheelbase of 2765mm, the widest body of the same class of 1890mm, and the shape design is more ingenious. The majestic scientific and technological shape and the "picturesque" artistic details have comprehensively upgraded the overall look and feel, so that consumers can "feel the full sense of luxury across the screen".
The front face of the new third-generation Roewe RX5 adopts the "phoenix" shape of the Bird of Honor, and the pieces of phoenix feathers on the grille are exquisite and shiny, and the high-end atmosphere overflows through the neat and varied arrangement. The headlights adopt the popular through-line light strip, with the newly designed left and right light groups, not only visually sharp, but also the lighting effect is also very technological. The longitudinal turn signals below are arranged in the front grille through a hidden design, which can display different light languages according to different driving conditions, bringing users a trendy experience and fully highlighting the luxury technology attributes.
In terms of details, the new third-generation Roewe RX5 is also particularly carefully crafted, so that the whole vehicle exudes a good artistic atmosphere.
