SAIC Roewe's RX5 model is a household name, and has been updated to the third generation, and SAIC's 1.5T supercharged direct injection engine will also usher in a new model. Driving line of sight this time to lead everyone to deeply reveal this 1.5T supercharged direct injection engine GS61, on the basis of inheriting the "double ten" powertrain gene, to achieve a comprehensive improvement of "re-upgrade".
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, to achieve 188 horsepower maximum horsepower. In addition, the SAIC Blue Core Power 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 let consumers eat a "reassuring pill".
Of course, the GS61 has more to offer than just its powerful power and ultra-low fuel consumption. SAIC Lanxin Power GS61 engine is equipped with high and low temperature dual circulation cooling system, thermal management module/double thermostat and electronic water pump EWP and other technologies, 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.
The engine can also reduce friction losses by 21% compared to the previous generation, increase the maximum thermal efficiency to 40% compared with the previous generation, through the combination of electronic water pumps, Fast VVT, pendulum dual-mass flywheels, continuous variable oil pumps and water-cooled intercooler systems, low-tension timing transmission systems, and shaft journal size optimization, friction-reducing coatings, and a 30% increase in the efficient operating area of the entire powertrain compared to the previous generation.
SAIC Blue Core Power GS61 engine in the NVH optimization, the engineering team also made sufficient 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.
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. In the production workshop, it is full of large-scale, intelligent and automated assembly lines, and an engine can be off the production line every minute on average, which can achieve an annual production capacity of 300,000 units. Not only that, but the plant has the strength to produce engines with completely independent intellectual property rights and reach the world's first-class level.
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. As one of the major projects in Zhengzhou to promote the high-quality development of the manufacturing industry, saic motor Zhengzhou Engine Branch Phase I project construction area of about 40,000 square meters, annual production capacity of 300,000 units, covering the engine block, cylinder head, crankshaft machining line and engine assembly line 4 automated production lines, the main product is the GS6 series automotive engine. This engine is independently developed by SAIC Motor, is the first product launched by SAIC Zhengzhou Engine Plant, and is also the first engine product with the most new technologies used by SAIC Group. On the basis of inheriting the "Double Ten Best" powertrain gene, the "re-upgrade" of comprehensive improvement has been realized.
