W12 refers to the 12 -cylinder engine arranged in W -type. The 2017 A8L W12, which has been suspended, is equipped with a 6.3L displacement engine that has basically reached the limit of mass production cars. The time four -wheel drive system cooperates with it. The 12 -cylinder engine of "W" layout is 368kW and the torque is as high as 625N.M. The W12 engine can only accelerate the A8L of the behemoth from static to 100km/h at only 4.7S.
The W12 in front of the Audi A8L front, that is, the two V6 engine cylinders are tied to form a W angle of W. The engine has a total of 12 cylinders, so it is called W12. [Features of the new engine of W12] Compared with previous technologies, the new Audi 12 -cylinder engine has irresistible advantages. It is compact, powerful, and light weight. Because the length of this engine is only 513mm and the width is 690mm, it can be installed in front of the car and can be combined with the four -wheel drive system. The new W12 engine design is compact, coupled with light metal materials such as aluminum and mirror, which makes this 12 -cylinder engine has another advantage. This is the light weight. The Audi A8 L6.0 Quattro sedan used the W12 engine, and the weight of the entire vehicle was unprecedentedly reduced to 1980kg, which was lower than all other models. The weight of the car unit's horsepower is only 4.7kg, which competes with high -performance sports cars. Compared with the previous design, this engine is no longer a classic W12 engine, because it does not use a three -row separation configuration, but places the three links on the same cranks axis. This new 12 -cylinder engine jointly developed by Audi and Volkswagen is indeed different.
In the history, there have been examples of using the W -type design engine in history. As early as the 1920s, some people had designed a legendary "tear drop" car. The designer of the car uses a 3 × 2 arrangement and 6 -cylinder engine. A few years later, cars with W12 engines with W12 engines, 24L, and 370kW were appeared. The three had drove this car to create a world record. 70 years ago, in the fall of 1931, Hohhy took the lead in designing a 12 -cylinder engine for batch production, becoming a milestone in the history of German automotive development. Hohhy later became one of the origins of the Audi brand. It installed a V12 engine in a convertible. The engine, like the new W12, is a 6L engine. Audi is one of the manufacturers currently using a dual V -type or W -type series of 12 cylinder manufacturing engines. The design principle of the W -type engine has very significant characteristics: Although the number of cylinders is large and the displacement is large, the volume of the W12 new engine is as large as the V8 type, which is much smaller than the traditional V12 type. Compared with previous technologies, the new Audi 12 -cylinder engine has an irresistible advantage compared to previous technology. It is compact, powerful, and light weight. Because the length of this engine is only 513mm and the width is 690mm, it can be installed in front of the car and can be combined with the four -wheel drive system. However, other types of 12 -cylinder engines can only match the rear -wheel drive system due to large volume. Because the lower part of the engine in front of the car does not have enough space to accommodate the front -wheel drive component. The design of the new W12 engine is compact, coupled with light metal materials such as aluminum and mirror, which makes this 12 -cylinder engine has another advantage. This is the light weight. The Audi A8 L6.0 Quattro sedan used the W12 engine, and the weight of the entire vehicle was unprecedentedly reduced to 1980kg, which was lower than all other models. The weight of the car unit's horsepower is only 4.7kg, which competes with high -performance sports cars. Compared with previous design, this engine is no longer a classic W12 engine, because it does not use a three -row separation configuration, but places the three links on the same crank. This new 12 -cylinder engine jointly developed by Audi and Volkswagen is indeed different. Pay attention to the cylinder arrangement of the engine and find that the machine is made of two sets of ultra -small V6 assemblies. Each group has six cylinders and arranged 15 ° angle. This bias arrangement has the advantages of the classic V6 4 -cylinder engine, and its width and length are reduced to a minimum. Another advantage of connecting these two rows of cylinders into 72 ° is that the height of the engine is significantly reduced, which means that the front end of the car can be designed to be flat, and it is richer in the sense of flow. Another advantage is that it brings unique dynamics to high -end cars, which may be the most hopeful. The core component of the W12 engine is a crankshaft transmission device with seven bearings with a weight of only 20.5kg. The crankshaft is configured with a biased configuration, which can maintain a constant ignition order like a V6 engine. The overall rigidity of this engine is also unusual. The comfort of its excellent vibration resistance even exceeds the expected level of the 12 -cylinder engine. To ensure extraordinary performance, the Audi W12 engine adopts a dry lubrication system. The biggest superiority of the dry lubrication system is: even in the state of high side acceleration, it can provide the engine with lubricating oil in the best way. It is different from ordinary wet lubrication systems. The oil pump provides lubricating oil from a separate fuel tank to the engine. This method is more convenient for the optimization design than ordinary ways. The lubricant of the Audi W12 engine is behind the right front headlights and connects to the engine through two hoses. The oil pump is driven by a chain directly connected to the crankshaft. The water cooling system on the left side of the engine can ensure sufficient cooling of lubricating oil. This system is rarely applied to batch -produced cars and can only be used in high -end sports cars. Optimized design reduces the double -top camshaft on each row of the exhaust gas emissions. The camshaft is driven by the same chain and operates the two airways and two exhaust valves of each cylinder through the roller camson with a low friction coefficient. This design principle helps significantly reduce fuel consumption. The adjustment range of the variable ventilated time device is very wide, the valve is 52 °, and the exhaust valve is 22 °. This means that the best valve opening time can be achieved throughout the engine speed range, and at the same time, it can also achieve good idle emissions, reduce the discharge of unrealistic combustion particles, and maintain sufficient torque at the entire speed range. The hybrid of oil and gas is completed by Bosch Motronic ME7.1.1 electronic order fuel injection system. The device includes electronic valve control, thermal membrane air flow meter and variable air -fuel ratio control. Four burst sensors can accurately measure the cylinder that produces burst. The engine's control of the exhaust emissions mainly relies on 4 three -yuan catalytic switching device installed near the engine and two main catalytic switch placed in the muffler. Eight automatic heating oxygen sensors continuously monitor the exhaust tail gas. Therefore, such a powerful engine can also work hard to meet the requirements of the European III standard for tail gas emissions. The veritable 12 -cylinder sound features are undoubtedly. The charm of the 12 -cylinder engine is largely due to its special acoustic quality. For this reason, these special acoustic requirements also pay attention to these special acoustic requirements during the development process. This requirement should have an excellent and extremely low vibration quality when idling, especially at some load acceleration processes and at a constant speed. At the same time, acoustic engineers have designed a very dynamic, strong and elegant sound mode for the engine's load acceleration. This distinctive sound design integrates the highest acoustic quality and warm emotional color into one, becoming a typical feature of the excellent overall performance of the vehicle.
Audi A8L 6.012 is exquisite, high -speed stability, and sensitive braking. The gearbox is not fast enough. Prices (RMB): At the same time that the A8 car key was received by Audi, they also received their instructions: it is best to get familiar with the operations of A8 first. Although it was the first time I tested the new A8, I have tried a lot of good cars before and consciously do not need to learn the operation of A8, but I still respect their goodwill reminders, okay, then familiarize it. Sitting in the car and looking around, the familiar taste and the seemingly known operating panel made me feel at ease, as if I came to an old friend's house as a guest without any strangeness. Black -bottomed red -character instrument panel, dual temperature area automatic air conditioning, electronic parking brake and that fashionable MM, the system is similar to the new A6. If you have previously driven the Audi car, you don't need to be familiar with it. However, on the side of the gear bar, I still found a fresh object -the start -up button with fingerprint recognition function. In my impression, only an office building similar to the US FBI will have similar equipment, and in cars, such designs are rare. According to the guidance of the staff, I first adjust the position of the seat and steering wheel, lock the radio to the favorite channel, and solemnly press my right index finger on the fingerprint recognition instrument. The attempt was not successful, wiped the fingers and tried it again. After a few seconds, the computer display was successful. All settings were entered into my fingerprint files. When I started with this finger, I used this finger to start A8, seats, audio and air conditioners, etc. The device will return to the location I originally stored, but this identifier sometimes cannot recognize the fingerprint. Try it a few more times. In the large body of A8, the driver looks a little small, but the A8 is not laborious. The steering wheel is very light at low speeds. It is no different from the domestic A4. The wheelbase and 5.2 -meter body should always be wrapped more when turning around, otherwise the beautiful wheels will be in danger of the road to the road. On the highway, the long body is not a burden. Instead, it increases the high -speed stability of A8, and has a natural advantage in the long wheelbase in the long -wave road bumps. Looking at A8's huge wheels and sports tires of 255 40 R19, can I have a little concern in my heart. Can the tires with a flat ratio of only 40 can adapt to China's road conditions? Will it be bad when passing the gap? With such concerns, we are on the road. We are careful during the test drive in a few days. We all slow down all places where there are some bumps on the road, for fear of a tire problem, but fortunately, when the car is returned, these four beautiful tires It's intact. As the top product of Audi, the interior of A8 is comparable to Mercedes -Benz S and BMW 7. When I went to the Frankfurt Auto Show in September, I saw an interesting article in the hotel, probably the meaning of which car manufacturers were premium brands. Make a brand in other countries. The focus of disputes is concentrated in whether Audi should be calculated in the same first -line brand camps as Mercedes -Benz and BMW to form a 2 1 competitive pattern. According to the report, neither Mercedes -Benz and BMW's seniors said at the same time as euphemistically that Audi and their brands were still a bit different. However, is Audi comparable to the two luxury car manufacturers? Is there a say in manufacturing high -end cars? We believe that only after detailed and deep tests can we understand and judge.
