Strong domestic "core" dirty, analysis of the third generation blue core 2.0T black label engine

Publish Date: 2022.09.26

As the heart of the automobile, the internal combustion engine has played an irreplaceable role since the birth of the automobile. With the progress of manufacturing industry and the development of science and technology, internal combustion engines are also experiencing changes again and again. In the hearts of car enthusiasts, the internal combustion engine is like a miracle. However, with the arrival of the era of electrification and new energy, the internal combustion engine has been gradually replaced by the motor, which has disappointed some people who are keen on enjoying the pure driving experience of internal combustion engine.

However, even though the current environment is developing towards new energy and electrification, there are still some brands dedicated to internal combustion engines that have not given up the research and development of internal combustion engines. For example, this brand with sports genes in its bones, SAIC Mingjue, recently released the first sports car model MG7 under the "black label". With the release of new cars, "the third generation blue chip 2.0T high-performance engine" also emerged. Today, I'd like to take a look at the highlights of this engine.

The blue core engine is a historical engine. Since 2014, SAIC and General Motors have jointly developed the first generation blue core engine. This product is the first direct injection supercharged 2.0T engine in China, and has won the "First Prize for Scientific and Technological Progress in China's Machinery Industry in 2016", providing strong support for the blue core strategy. SGE1.5T turbocharged direct injection engine, as the representative of its own brand, has won the reputation of "China Heart", the top ten engines in 2017, which is brilliant.

In 2020, SAIC began to independently research and develop the second generation of blue core engine products. Along the way, blue core technology continued to make breakthroughs in the pursuit of stronger power, higher efficiency, less emissions and lower noise. It is carried on many models under the company and has been praised by consumers and recognized by the market.

The third generation blue core engine, the main character of this article, has pushed the performance to a higher level. After comprehensive upgrading, as the power system of MG7, the first black label sports model under SAIC Mingjue, it is also full of confidence. It is worth mentioning that the engine used in the MG5 XPOWER TCR racing car is the racing version of the third generation blue core 2.0T black elevation performance engine.

It is a hard indicator to know whether an engine is powerful and whether its parameters are excellent. The third generation blue core 2.0T black elevation performance engine has a maximum output power of 192kW (261Ps) and a maximum output torque of 405M. m. At the same time, the thermal efficiency of this engine has also reached 39.3%. It is even better than the book data of LinkedIn 03+.

If you want to squeeze the limit of an engine and increase its durability, you must first make the engine have extremely high structural strength. The third generation blue core 2.0T black elevation performance engine adopts high pressure casting aluminum alloy body and gravity casting aluminum alloy cylinder head, which not only meets the requirements of high strength and durability, but also greatly reduces the weight of the engine, which is 15% lower than the previous generation engine, making it light and solid.

It is well known that the lower the turbine intervention speed, the faster the response, and the better the acceleration. Through the VGT variable cross-section turbocharging technology, the seamless switching between large and small turbines is achieved through the changes in the turbine. In the case of low speed and low exhaust flow, the flow through the section is controlled through the nozzle ring, so as to improve the intake pressure and improve the inherent response lag defect of traditional turbochargers. The speed to reach the peak torque is only 1750rpm, and the time is also shortened by 30%. The direct feeling is that the engine responds faster, The accelerator is more flexible.

The third generation blue core 2.0T black elevation performance engine not only has scientific and technological support in power, but also has outstanding performance in fuel economy. DVVL intelligent variable valve lift technology can reduce the throttle loss at the throttle valve, increase the intake pressure, increase the intake pressure, increase the cylinder pressure, consume less work in the air exchange process, and reduce fuel consumption under low engine load conditions. At the same time, the high lift state can increase the intake air volume, effectively improve the engine's transient responsiveness, and the 2000 rpm response time is increased by 28%. The comprehensive and accurate calibration control strategy has improved fuel economy by 5% and power performance by 3%. Officially, the fuel consumption can be as low as 6.2L/100Km.

In terms of fuel saving, the third generation blue core 2.0T black elevation performance engine also uses 350bar high-pressure direct injection system, variable displacement oil pump and other mainstream technologies in the industry. 350bar high-pressure direct injection system can reduce the oil drop to 6 μ M level, so as to promote the atomization of gasoline. The more fully atomized, the more delicate, and the higher the combustion efficiency. In combination with the new stepped nozzle design, it can reduce the coking of the fuel injector and improve the PN emission and fuel consumption; CVO small flow precise control technology is adopted to improve multiple injection and precise oil control, thus improving emissions, reducing oil dilution and early combustion. The pressure of the main oil duct is kept at a relatively constant value at medium and high speeds, which can meet the engine oil demand, reduce power consumption and play a role in energy conservation and emission reduction.

The NVH index of a car is good and many aspects should be taken into account, among which the NVH level of the engine is particularly important. The third generation blue core 2.0T black elevation performance engine has been optimized for combustion noise and special noise. Through Lanchester type balance shaft module and Zero tech high-strength sleeve chain technology, the friction of part gears has been reduced.

In terms of engine reliability, we have experienced more than 60 tests, and the total bench test time is more than 50000 hours to ensure the mature reliability of the engine mounted on the vehicle model.

At the end, through a series of black technology and the evolution of the three generations, SAIC's blue core engine is at the current mainstream level in terms of design structure, power performance, fuel economy and operation stability. At the same time, independent positive research and development also shows another breakthrough in the technology of independent engines. Coincidentally, the other day I had a deep static experience with the MG 7 equipped with this engine. After I had a deep understanding of the third generation blue core 2.0T black elevation performance engine, I was more excited about its dynamic performance.
