At the end of Speed and Furious 5, the protagonist evenly grabbed the 100 million US dollars snatched equally. One of the two little black brothers paid a lot of money and bought a cool sports car with “only 4 cars in the world and only 1 in the Western Hemisphere”. Who knows when he showed off to the second black brother beside him, the latter smiled indifferently, a sports car of the same model came leisurely-“Now there are two in the Western Hemisphere.”
This super-sports car, which opens 90 ° upwards and is used as a finale artifact by Speedy, is called Koenigsegg, a 47-year-old bald uncle, Christian von Koenigsegg. Koenigsegg). In early 2019, Evergrande, who was obsessed with “buy, buy and buy”, used 150 million euros to acquire 20% of Koenigsegg.
More than that, Xu Jiayin personally planned the Evergrande automobile project “Hengchi Automobile” and also established a joint venture with Koenigsegg through its subsidiary NEVS to provide technical support for Hengchi Automobile. The joint venture agreement even states that “Koenigsegg agreed to grant the project company certain intellectual and industrial property licenses no later than one month before the production of the car.”
One year later, in Geneva, which became an online live car show due to the outbreak, Koenigsegg emerged from this young brand (founded in 1994) The boldest and craziest step since its birth-a new four-seater super GT sports car, Koenigsegg Gemera .
Who are you?
What kind of brand is Koenigsegg? It is a small Swedish independent supercar factory with little interest in the consumer market and motorsports. Instead, it focuses on creating crazy fast cars with top speeds of 400 + km / h.
Like many contemporary super-running small workshops, at first, Koenigsegg did not have the ability to develop the core power system by himself, but instead used his compatriot Volvo’s V8 engine to modify it. However, the result is that relying on the magical brain under von Koenigsegg’s bald head, such a “patch-up” of the Koenigsegg sports car will often pull Bugatti back from the top of the world’s speed record against the popular empire. It is also a million-level god car. Bugatti is the giant Goliath, and Koenigsegg is the shepherd boy David.
Matching the crazy speed record is the rare double-digit or single-digit production of each model of Koenigsegg, and the high price of starting at the level of ten million yuan. Therefore, Koenigsegg in “Fast Exciting 5” will appear when the protagonist is full and happy.
Speaking of the brand background, what about this time? Koenigsegg ’s new car, Gemera, is a 2.0T three-cylinder, hybrid, four-seater sports car-if you know a little bit about the car, you should understand that these three labels are important for Ke Super running brands such as Niseg are like Hermes linked with “cotton fabric”, “buy one get one free” and “large capacity”.
If this is not magical enough, it is even more incredible that Koenigsegg still uses the above three common tags of “salted fish car”, but still allows Gemera to have a terrifying performance of 1.9 seconds to accelerate to 100 and 400km / h. , Without disgrace Koenigsegg logo. While(Valve lift) is fixed, but the ideal valve timing and valve lift will change from time to time with different engine speeds. As a result, the engine cannot keep the amount of air involved in the combustion always at the desired value for combustion, which naturally limits the improvement of thermal efficiency.
In order to break through the efficiency bottleneck brought by the air intake system, various traditional car manufacturers have also made many efforts over the years. Honda’s famous VTEC, BMW housekeeping skills, VANOS and Valvetronic, Toyota VVT-i and other valve control technologies use mechanical or electronic control methods to achieve multi-stage or stepless adjustment of valve timing and / or valve lift. However, these technologies are still optimization methods based on the camshaft structure. They have not fundamentally changed the limitations of traditional structures on valve control. “Limited freedom” and Freevalve’s “unlimited freedom” are not the same.
As for Freevalve, it simply means- What timing chain and camshaft, I do n’t want to use it all. Is it difficult for me to control the valves individually and directly with computer electricity?
Koenigsegg uses a set of electronically controlled air + oil lines to drive the actuators to control 12 valves of three cylinders (2 per cylinder Intake 2 Exhaust) . In this way, not only the heavy and increased mechanical timing system is discarded, but also stepless and precise control of each valve can be achieved.
