Recently, the SAIC blue core power gs61 1.5T supercharged direct injection engine will be displayed for the first time in SAIC Zhengzhou engine factory. On the basis of inheriting the top ten engine genes of the previous generation SAIC blue core power “China heart”, the engine has comprehensively evolved in power, economy, silence and quality. This engine will be the first to be equipped on the third generation Roewe rx5 model.
The total investment of SAIC Zhengzhou engine plant phase I project is 1.476 billion yuan. The production workshop covers an area of nearly 40000 square meters and adopts digital, intelligent and automatic assembly lines. On average, one engine can be offline every more than one minute, which can achieve an annual production capacity of 300000 units.
The factory covers four automatic production lines of engine cylinder block, cylinder head, crankshaft machining line and engine assembly line. It adopts world-class engine manufacturing equipment with strong flexibility, high precision and fast speed. It has the strength to produce engines with completely independent intellectual property rights and reaching the world-class level. As the first product put into operation in the factory, SAIC bluecore power gs61 1.5T supercharged direct injection engine inherits the excellent gene of “China heart” top ten engines, and is comprehensively upgraded from five aspects: combustion optimization, gas exchange, heat management, friction reduction and NVH.
In terms of technology, SAIC bluecore power gs61 1.5T engine adopts a new generation of SGCs combustion system, 350bar high-pressure fuel injection system and electronically controlled variable section turbocharger, so that its maximum power can reach 188 HP and maximum torque can reach 300 n · M. compared with the second generation products, the maximum power and maximum torque are increased by 7 HP and 15 N · m respectively, which is at the leading level of 1.5T turbocharged engine with the same displacement.
The engine also adopts the combination of electronic water pump, fast VVT, pendulum double mass flywheel, continuously variable oil pump, water-cooled intercooling system, low tension timing transmission system, journal size optimization, friction reducing coating and other technical measures, so that the friction loss is reduced by 21% compared with the previous generation of products, the thermal efficiency reaches 40%, and the efficient operation area of the whole power system is increased by 30% compared with the previous generation of products. In addition, SAIC bluecore power gs61 1.5T engine is also equipped with high and low temperature double cycle cooling system, electronic water pump, double thermostat and other thermal management technologies, supplemented by intelligent software control strategy to cover the thermal management requirements under various driving scenarios. Significantly improved cold start emissions and warm-up rates, resulting in better fuel economy. According to the official introduction, the new third-generation Roewe rx5 has a fuel consumption level of 6.0l/100km (NEDC), which is satisfactory for a compact SUV with large size.
In NVH optimization, through the strengthening of the engine body structure, the lightweight design of the crank connecting rod mechanism, and the application of acoustic packaging in key parts such as timing cover and fuel system, the sound power level and idle noise have reached the international leading level. At the same time, in terms of durability, SAIC bluecore power gs61 1.5T has the support of world-class parts suppliers such as Bosch, vipai, bogwarner, Mahler, Schaeffler, tennac, Valeo and Eaton, with the support of global leading technology. After more than 60 special tests, the bench test has accumulated more than 55000 hours, and has completed nearly 5 million kilometers of vehicle test under various complex climatic conditions. Its reliable quality can withstand extreme tests.
In terms of appearance, the third generation Roewe rx5 will adopt a new design language, a new “phoenix” front face shape, combined with through lamp strips and sharp matrix LED headlights on both sides, which has a high visual impact.
The side lines of the car body are also more relaxed. It is equipped with a new petal style 19 inch rim and a black exterior rear-view mirror to make it look more classy. In addition, the new car is also equipped with a hidden door handle with a strong sense of science and technology, which can not only improve the visual effect, but also effectively reduce the wind resistance.
In the rear part of the car, the new car has also carried out a new design, with sharper tail lines, and is equipped with a new through tail lamp group, which can effectively improve the visual width. In terms of body size, its length, width and height are 4655 / 1890 / 1655 (1664) mm respectively, and the wheelbase is 2765mm, which has been greatly improved.
summary
As the leader of SAIC Roewe in compact SUV products, rx5 has won the recognition of many consumers with its beautiful appearance, spacious space and comfortable driving quality. Four generations of products have been iteratively updated in five years, which can see the vitality of rx5 series. The third generation Roewe rx5 is also coming to us. In addition to the new upgrade of size and design. The new car will also take the lead in carrying SAIC bluecore power gs61 1.5T engine, which will further improve the product power.
