Probably many people know the Changan Blue Whale engine, which has great horsepower and strong torque. So how strong is it? It has to be pulled on the track to test it. So Changan participated in the CTCC China Touring Car Championship. Changan Automobile Blue Whale Team, which debuted in the CTCC arena in 2021, as a team participating in the NGCC category, has been galloping all the way since the beginning of the season, and has continuously staged championship performances. At Shanghai Jiading Station, on the F1 track of Shanghai International Circuit, Changan Automobile Blue Whale Team won the double championship of the Drivers' Cup and the Manufacturers Cup in one fell swoop, won the first title of the NGCC Cup in the 1.5T era, and created the fastest lap in the whole game with a time of 2 minutes and 28.278 seconds.
In the second battle of Hunan Zhuzhou International Circuit, Changan Automobile Blue Whale Team won the top three in the final of the sixth leg of the NGCC Cup, winning the driver's cup and the manufacturers' cup double crown again, and setting another fastest lap time in the whole game with a time of 1 minute 52.325 seconds.
Shanghai Songjiang Sheshan Station, in the 9th, 10th and 11th round finals of the NGCC Cup, Changan Automobile Blue Whale Team won three consecutive Drivers' Cup championships and three Manufacturers Cup championships, and once again won the top three in the ninth round final, and driver Cui Yue ran the fastest lap of the season in 1:09.947 seconds in the eleventh round.
At the end of the season, the 68th Macau Grand Prix - CTCC Macau Caravan Cup, Changan Auto Blue Whale Team, as the first Chinese independent brand team to land in the event, won the first and second round final championships at the Guia Circuit, showing the performance strength of China's own brand cars with "two consecutive championships". Blue Whales driver Wan Jincun successfully won the CTCC 2021 Driver of the Year Championship. Changan Automobile Blue Whale Engine won the 2021 CTCC "Official Recommendation best engine" award.
Of course, this blue whale engine is also widely installed in Changan's SUVs, such as the second-generation CS55 PLUS. Not long ago, Changan conducted a live broadcast about the power test of the second-generation CS55 PLUS, which turned out to pull a trailer truck with a total weight of more than 90 tons.
So what is so special about this 1.5T Blue Whale engine? This engine is jointly developed by Changan Headquarters and Changan Uk Center, and built with internationally renowned suppliers, with a number of global leading technologies, interpreting the leading research and development concept of "strength, static and net", the maximum power rating is 138kW, the net power is increased by 8%, and the peak torque of 1500r/min (1500-4000r/min) is 300N·m, so that the turbo hysteresis is reduced to not be perceived by the driver. The fuel consumption of 100 kilometers is only 5.9L, which meets the national 6b emissions, realizes the coexistence of strong power and fuel economy, and the 1.4T and 1.5T high-pressure direct injection engines on the same platform have won the honor of the top ten engines of "China Heart" in 2019 and 2020.
The reason for the strong power is mainly due to its dual outlet integrated exhaust manifold, which effectively reduces the exhaust interference of the engine, enhances the exhaust pulse, and improves the power output; at the same time, the cooling water jacket surrounded by IEM effectively improves the heating speed and the exhaust temperature of the heat engine and improves the combustion efficiency. In addition, twin-scroll electronically controlled turbocharging is used: the turbine hysteresis is effectively reduced, and the peak torque of 300N .m can be reached at 1500r/min.
In addition, there is also an original "AGILE Agile" efficient ultra-clean combustion system: 350 bar high-pressure injection of atomized fuel and high-roller flow air duct formed by the air flow movement closely match, to achieve a uniform mixing in the cylinder, a 30% increase in turbulence kinetic energy in the cylinder, an even improvement of 8.2% in the mixing, and an excellent combustion rate. And intelligent lubrication system: the use of fully variable displacement oil pump + controllable cooling piston nozzle (PCJ) and low viscosity oil, the formation of intelligent lubrication system, to achieve the whole machine ultra-low friction, to achieve excellent fuel consumption level.
The engine on the second generation of Changan CS55PLUS is matched by the Blue Whale 7-speed wet dual-clutch transmission, equipped with a number of innovative technologies of intelligent pre-retardation, ready to go at all times; the comprehensive transmission efficiency is as high as 94.3%, the surging power lossless output, no sense of switching, rapid response, cash in love, no need to wait. The gear change is fast and soft, and the extreme linear power output brings a smooth acceleration experience, like flowing water. The transmission intelligently lowers the gear according to the degree to which the driver brakes, and uses the lower gear to output more torque when accelerating again, ready to move and wait for the opportunity.
Changan's blue whale engine opened the first year of China's automotive power technology platform and opened the curtain of high-pressure direct injection engine. In addition, with new products that embrace electrification, we can achieve unprecedented power presentation with leading environmental technology. On the occasion of the second anniversary of the release of the Blue Whale Power brand, Changan Automobile launched the Blue Whale iDD Hybrid System (intelligent Dual Drive) after more than 500 engineers from 10 countries and continuously honed for 6 years. Blue Whale iDD represents the global intelligent oil-electric dual-drive system, the whole domain is the "full speed domain, full field domain, full temperature domain, full time domain" collectively referred to, it can be applied to all models of A-class -C class platform.
Blue Whale iDD realizes the organic integration between high-performance Blue Whale engine, high-efficiency Blue Whale electric drive transmission, super capacity PHEV battery and intelligent control system, so that users can get an infinitely close to perfect driving experience without anxiety in any current scene and at any time.
This 1.5L turbocharged engine, with a maximum power of 126kW, a maximum torque of 260Nm, and a maximum thermal efficiency of 40.8% on the platform, will be further evolved in the next 5 years, applying a series of new technologies such as variable valve lift, variable-section electronic turbocharging, etc., to achieve 45% thermal efficiency.
Blue Whale iDD can ensure an instantaneous power explosion and a comfortable driving experience in low-speed starting, high-speed overtaking, and extremely high-speed tracks. The peak torque response of the millisecond motor can reach 0.6g in the initial stage, the fastest acceleration time of the platform is 6s+, and the maximum speed can easily reach 200km/h. Commuting in the city and long-distance travel are the home of Blue Whale iDD's unavoidable advantage. On the two-ton SUV, the fuel consumption of the Knoll is as low as 5L/100km, the pure electric endurance is 130km, and the comprehensive endurance is 1100km; even in the state of the power, the power is just as surging. In terms of fuel consumption and power, "fish and bear paws can be obtained at the same time".
At present, UN-K's Blue Whale iDD has been launched, which adopts AC and DC dual fast charging technology, covering the needs of multiple scenarios such as efficient charging of households and fast power replenishment for travel; the pool power is as high as 30.7kwh, and the pure electric mileage reaches 130km; the battery pack has reached the strongest protection level in IP68 countries, and is equipped with one-on-one battery intelligent safety butler, 24-hour uninterrupted security monitoring, all-weather protection of the user's car safety.
After two years of development, Changan Blue Whale power system has gradually covered many models of Changan, and has also achieved remarkable results. From January to November 2021, Changan Automobile achieved overall sales of 2122511 units, an increase of 17.7% year-on-year. While the overall sales exceeded the 2.1 million mark, Changan Automobile's sales in 2021 have surpassed the whole of 2020 ahead of schedule! Among them, the sales of Changan Automobile's "Blue Whale Family" model equipped with Blue Whale NE series engines exceeded the 900,000 mark from January to November. The "Blue Whale Family" has sold 2.42 million vehicles and continues to hold high the benchmark banner of China's automotive power technology.
