For fuel vehicles, buying a car is buying an engine, a good engine is very important for the value of the whole vehicle, after the announcement of roewe's new RX5 vehicle rendering, its power system, SAIC Blue Core Power GS61 1.5T supercharged direct injection engine in SAIC Zhengzhou Engine Factory has also been exposed.
Inheriting the last generation of SAIC Blue Core Power "China Heart" Top Ten Engine Genes, the GS61 1.5T supercharged direct injection engine has a very high starting point, and this engine has been comprehensively upgraded in five aspects: combustion optimization, gas exchange, thermal management, friction reduction and NVH.
The use of a new generation of SGCS combustion system, with a 350 bar high-pressure fuel injection system and an electronically controlled variable-section turbocharger, bursts out a maximum torque of 300 Nm, achieving a maximum horsepower of 188 hp, through the electronic water pump, Fast VVT, pendulum dual-mass flywheel, continuous variable oil pump and water-cooled intercooling system, low tension timing transmission system, as well as shaft journal size optimization, friction reduction coating and other technical measures, so that the friction loss is reduced by 21% compared with the previous generation of products. The maximum thermal efficiency is increased to 40%, the efficient operation area of the whole power system is increased by 30% compared with the previous generation, and the fuel consumption per 100 kilometers is 6.0L/100km.
At the software level, SAIC Blue Core 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 control strategies, covering the thermal management needs of various driving scenarios. Through the reinforcement of the engine body structure and the lightweight design of the crank linkage mechanism, as well as the application of acoustic wrapping in key parts such as timing covers and fuel systems, supplemented by finer calibration optimization, the acoustic power level idle noise has reached the international leading level, which can bring a library-level quiet experience to the interior.
It is understood that SAIC Blue Core Power GS61 1.5T engine from the total investment of 1.476 billion yuan SAIC Zhengzhou Engine Factory Phase I project, the engine will undergo more than 60 special tests before leaving the factory, the bench test accumulated more than 55,000 hours, in a variety of complex climatic conditions completed nearly 5 million kilometers of vehicle testing, the plant can achieve an annual production capacity of 300,000 units. In addition, with the blessing of world-class parts suppliers such as Bosch, Wispan, BorgWarner, MAHLE, Valeo and other world-class parts suppliers and the world's leading technology, the product strength of the SAIC Blue Core Power GS61 1.5T engine has also been enhanced, and we are still looking forward to the power performance of the third-generation RX5 after its listing.
