Although it will take time for the new third-generation Roewe RX5 to be officially launched, with the gradual disclosure of details, the roewe family's blockbuster model has once again appeared in the public spotlight. Recently, SAIC Roewe unveiled for the first time the third-generation 1.5T supercharged direct injection engine of SAIC Blue Core GS61 equipped with the new car.
SAIC Roewe said that this GS61 engine, independently developed by SAIC Motor, is the first product launched by SAIC Zhengzhou Engine Factory. Compared with the previous generation, the GS61 engine has been upgraded and optimized in terms of combustion optimization, gas exchange, thermal management, friction reduction and NVH, etc., to improve product performance in all aspects. BY ADOPTING A NEW GENERATION SGCS COMBUSTION SYSTEM, COMBINED WITH A 350BAR HIGH-PRESSURE FUEL INJECTION SYSTEM AND AN ELECTRONICALLY CONTROLLED VARIABLE-SECTION TURBOCHARGER, SAIC BLUECORE ACHIEVES 188 HP MAXIMUM POWER AND 300 NM PEAK TORQUE WHILE TAKING INTO ACCOUNT FUEL ECONOMY.
According to saic motor Roewe's introduction, this engine applies electronic water pump, Fast VVT, pendulum dual-mass flywheel, continuous variable oil pump and water-cooled intercooling system, low-tension timing transmission system and other technologies, optimizes the size of the journal, increases the friction reduction coating, etc., so that the friction loss is reduced by 21% compared with the previous generation of products, the maximum thermal efficiency is increased to 40%, and the efficient operation area of the whole power system is increased by 30% compared with the previous generation. It is reported that with the help of the GS61 1.5T engine, the comprehensive fuel consumption of the new third-generation Roewe RX5 NEDC is only 6.0 liters per 100 kilometers.
The powerful power output is inseparable from the assistance of accurate software strategy. SAIC Lanxin Power GS61 1.5T engine is equipped with high and low temperature dual circulation cooling system, electronic water pump and double thermostat and other thermal management technologies, supplemented by intelligent software control strategies, covering the thermal management needs of various driving scenarios.
In terms of NVH optimization, the global engineering team of SAIC Blue core power GS61 1.5T engine has also made great efforts. Through the strengthening of the engine body structure, the lightweight design of the crank linkage mechanism, the application of acoustic coating in key parts such as timing cover and fuel system, and the fine calibration optimization, the acoustic power level idle noise of the GS61 engine has reached the international leading level, which can bring a library-level quiet experience.
SAIC Roewe said that the GS61 1.5T engine has undergone more than 60 special tests, the bench test has accumulated more than 55,000 hours, and has completed nearly 5 million kilometers of vehicle tests under various complex climatic conditions, and its durability and reliability can withstand extreme tests. In addition, SAIC has also worked closely with world-class parts suppliers such as Bosch, Viva, BorgWarner, MAHLE, Schaeffler, Tiannak, Valeo, Eaton and other world-class parts suppliers, further enhancing the product strength of the GS61 engine.
The SAIC Blue Core Power GS61 1.5T engine is manufactured by SAIC Zhengzhou Engine Plant. At present, the first phase of the plant has been put into operation, with a construction area of 40,000 square meters, a total investment of 1.476 billion yuan, and an annual production capacity of 300,000 units. After completion, the entire SAIC Zhengzhou engine plant will cover four automated production lines of engine block, cylinder head, crankshaft machining line and engine assembly line, becoming the largest engine manufacturing base of SAIC Group in China.
