triangle, the most stable plane pattern, by extended out of the “triangle” is the term often used to describe seamless interoperability between three and inseparable state, such as “Naruto” in the “pig deer butterfly”, “Piece” of Aspen, Saab, road fly like. In fact, in addition to the relationship between the characters, some of the highlights of the characteristics of a car is also able to form a solid triangle relationship.
Nissan technology, people, cars, life. This is a familiar Nissan slogan, and perhaps many Nissan fans favorite word, after all, be able to reflect their car based on “flow technology,” he said.
hard work “technical Nissan” method
technology is the solution to any problem, automotive industry all the time in the face of restructuring, as the main technology of the Nissan brand, how to secure their market position? The creation of new technology is the best way out.
Often people think of electric vehicles is only the beginning of the transition in recent years, but for Nissan, the relationship between the internal combustion engine and the electric motor seems to be to make up for each other constantly iteration, so it is a motor engine technology or technology in the history of the timeline are able to see the glorious moment of Nissan left.
Nissan power from the West to absorb the technology to build their own engine-leading technology with a 80-year period. In the 1960s for Nissan is an important time node, previously, the use of Austin’s technology as a power source of the vehicle, after the start of the autonomous power systems research and development.
Nissan VG20ET
C series, G series, A series, Y series, L series, E series, CA series, MA series engines have appeared, mounted on top of different models; 1983, Nissan introduced the VG series engine is Japan’s first production V6 engine, breaking the Japanese car companies can not produce the history V6 engine. After
RB26DETT
The FJ series inline four-cylinder engine, RB series inline six-cylinder engine with strong power output characteristics become the choice of many performance car enthusiasts. Including the 1989 launch of the RB26DETT, mounted on SKYLINE GT-R as it is broadcast, “Initial D” became a household name.
from the next in 1995, VQ series engine with excellent ride comfort, without procrastination power output, high economic and other characteristics, Ward 14 consecutive years top ten engines, it can appear in many luxury cars it also marks the Nissan power technology and truly entered the ranks of the world’s leading, and prepared the way for the emergence of ultra-behind VC-Turbo engine of change.
Next we look at Nissan in pure electric field of technological development, as already said, it began to develop electric cars are not in recent years, in 1947, Nissan will launch the first electric car Tama, 4.5Ps powered by a motor, a top speed of 34km / h.
Nissan EV4-P
and in the late seventies, the new Nissan-developed electric vehicle EV4-P launched a series of very strict harsh crash test, it can be said that created a precedent for pure electric vehicle crash test. EV4-P by the brake energy recovery system and the vehicle body lightweight FRP applications, so mileage of 302km, this data is now placed, may be regarded as the mainstream level.
Prairie joy EV
1983, Nissan launched the March EV is the world’s first car to use the asynchronous motor electric products; in 1996, prairie joy EV is the world’s first and was the only application cylinder equipped with lithium batteries and pure electric vehicles.
new Nissan LEAF
2017, the new Nissan LEAF electric vehicle technology, it should be electric powertrain system equipped with energy efficient, turn moments bigger, more robust power output, the maximum power of 110 kW, compared with the previous generation date LEAF improve yield percentage 38, the maximum torque of 320Nm, 26 to enhance the percentage of the vehicle acceleration has been further improved.
Nissan NOTE is equipped with e-POWER system
2018 Tokyo Motor Show, Nissan brings equipped with e- NOTE POWER chi movable charging technique. e-POWER chi charge Action Technology “equalization output power dedicated small fuel engines to generators, power input to the battery in storage, supplied to the motor driving the wheels at any time.
All of the above technological breakthrough allows Nissan conventional fuel vehicle and pure electric vehicles have a strong technical accumulation and reserves, under the so-called “technical Nissan” It is in their own products and technologies, the creation of the industry benchmark in the field under the car.
trend self-transcendence
Although the electric is the future trend, but Nissan did not stop the internal combustion engine research and development. the emergence of new technologies is not to “destroy” the original technology out, but to assist each other, make up through continuous investment in research and development, Nissan is currently in the field of vehicle fuel has developed a “hypervariable engine + super + Chi driving comfort technology” technology triangle, which is the seventh generation Teana masterpiece collection of the most advanced technology. [ 123]
2018, the seventh generation Teana debut, in addition to the more aggressive the next generation Nissan global design language other than V-Motion, the most talked about is “hypervariable engine + ultra + Comfortable driving technology “iron triangle consisting of a combination in which the hypervariable VC-Turbo engine engine can be said that the combination of the wisdom of the past two decades, Nissan power engineers.
linkage achieved by changing the piston stroke
born 2.0TVC-Turbo engine hypervariable engine after nearly 100 kinds of prototyping, accumulated 300 patents, after nearly 600 test vehicles worldwide test, more than 30,000 hours test stand test, more than 300 million kilometers of road tests, technological breakthroughs in engine stability, durability, processing techniques.
Compression ratio of 8: 1 to 14: 1 between the switch
Multi-connected
VC-TURBO engine by hypermutation in the conventional piston structure adds new design bar linkage mechanism, the control shaft to change the structure of the multi-link system, to achieve an increase or decrease of the stroke of the piston, and in accordance with the driver’s intention, different conditions, intelligent selection 8: 1 to 14: 1 between the optimum compression ratio, to solve the traditional conflict between power and fuel consumption, to achieve a “fish and bear’s paw” have both.
In just the last in 2019, the seventh generation Teana VC-TURBO hypervariable engine won the “double top” honors, including: November 4, 2019, won the 2019 annual “Chinese heart” ten Best engines; December 16, 2019, Ward won the 2020 ten Best engines awards, worth mentioning is that this is Nissan won the award for two consecutive years.
power to remove the core, the seventh generation Teana in science and technology in comfort before the continuation of the high level of standards, but also under a specific reinforcement on critical configuration. For example, the new 3D Multi-Layer ergonomic chair, the driver 30 to reduce the percentage of fatigue; double glazed glass sound absorbing material + double upgrade, the front windscreen and the side windows are made of a high strength double glazed glass, while the vehicle body plurality filling the plurality of sound absorbing materials, to maximize the noise barrier.
to make cars smarter
When it comes to make cars smarter, in addition to the seventh generation of the Nissan Teana has a core of “smart different from ordinary people,” the outside in smart driving also make a difference. Smart driving the automotive industry is already the hottest topic of the moment, while the L2 level of driver assistance systems is a mid-size car in the field of access standards.
Nissan Teana proved their strength lies with ProPILOT super intellectual drive system. First driving level, ProPILOT ultra-intellectual drive system complete shift in fully automatic mode, acceleration and braking and other operations, will sell the world’s first single-lane highway driving and driving navigation combination of driver assistance systems.
Nissan as early as 191998 began research and development of such technology, originally based on road conditions detected as the main purpose, after 20 years of driving assistance technology accumulation, ProPILOT super intellectual drive to become the first production car equipped with an automatic driver assistance systems, and in the world within the range achieved over 320,000 kilometers of road test and verification technology.
Meanwhile, Nissan Teana mounted NISSAN i-SAFETY intelligent active safety system, comprising: IEB intelligent pre-crash braking (dynamic monitoring pedestrians upgraded), the BSW lane change blind spot warning, CTA reverse side of the car alarm, IDA intelligent driver fatigue warning functions.
As for intelligent vehicle interconnected, Nissan has completed all the main vehicle-linked network layout. Currently, car networking platform has exceeded 1.1 million users. And Nissan joint China Unicom, high moral map, IFLYTEK, ink weather, cool music, Ali cloud, Tencent and other travel ecosystem partners. In the future, cars will achieve an annual joint iterative upgrade the system to provide a seamless connection of digital services.
to change the traditional car life
hypermutation engine, ultra-intellectual drive, comfortable Teana technology is currently owned technology triangle, although this structure has been strong enough, but in the future, we also hope that this triangle becomes more sharp than in the stable, how to achieve? And still before the same answer – the new technology.
mentioned earlier ProPILOT super intellectual drive system in the future will also be the focus of the Nissan upgrade iteration. The current plan is: in 2020, will have three models Nissan models equipped ProPILOT super intellectual drive; in 2021, will be based on the original super-intellectual drive on the completion of a new round of technology upgrades; to 2023, Nissan will achieve its All cars equipped with ultra ProPILOT intellectual drive, level models equipped with the percentage reached 70, entered the era of the autopilot.
Nissan IMX brain control concept car
In addition, Nissan is also working on Brain-to-Vehicle brain control vehicle technology, the system will allow the vehicle identification brain signals transmitted to the vehicle fasterAmong; then there Invisible-to-Visible technology that allows consumers to experience three-dimensional holographic navigation, full-aware and predict complex road.
We now look to Nissan’s vision to the next few years, in fact, just as in 1998, the original idea for the hypervariable engine. Hypervariable engine took 20 years to achieve, and achieve the ultimate driving ProPILOT ultra-intellectual form may not need such a long time. It is foreseeable that the next three to four years will be based on Nissan high technology as the leading light in time. [END]
