2. It has always been known for its leading technology. Nissan's engine technology is very advanced, ensuring strong power without sacrificing comfortable driving experience, and the so-called "Scorpio"? Ward's top ten engines? The VQ35DE engine and XTRONIC CVT continuously variable gearbox adopted by Teana and Sylphy represent Nissan's insistence on automotive technology.
For example, the 1.6-liter HR 16DE all-aluminum four-cylinder engine used by Tiida, combined with XTRONIC CVT continuously variable transmission, not only obtains good power, but also has better fuel economy. Today, with the rising oil price, Nissan's strategy seems to be more in line with the needs of consumers.
Nissan's own CVT continuously variable gearbox is also in the leading position in the world, which can transmit large torque, ride fast and consume low fuel. Maintenance-free for life? .
3. The price is declining, and the price of some models is even lower than that of domestic cars. For example, the price of Nissan Sunshine has dropped to about 60,000 yuan. In this price range, the cost performance is very high; Another example is Scorpio, which has dropped from the price of more than 200,000 to the current 1.6 million naked car.
4. Low failure rate and good fuel economy. Judging from our maintenance experience, Volkswagen used to maintain the most, but now it is GM, especially Buick models. Nissan has a low failure probability.
Nissan's engine and gearbox technology is superior to Honda's Toyota engine technology;
1, atomization fuel nozzle technology, the traditional fuel nozzle is 4 holes, and the daily design is 12 holes, which reduces the ejected fuel particles by 40%. The advantages are that the fuel injection range is reduced, the atomization effect is enhanced, and the combustion is more complete, thus obtaining greater vehicle power, saving energy and reducing emissions, and prolonging the life of oxygen sensors and three-way catalysis.
2. True circle processing technology. At first, this technology was used in F 1, and then it was gradually popularized in civilian vehicles. True circle machining can ensure that the inner diameter of the cylinder is farther. When the engine is running, the friction between the piston ring and the cylinder is more uniform and the sealing performance is better, which effectively increases the service life of the engine.
3. Continuous variable timing intelligent control system. This technology continuously opens the intake valve according to the change of engine speed. When the vehicle is driving at a high speed, the valve will open ahead of time, thus sucking in more air, increasing fuel injection and increasing power.
4. Variable intake control system (NICS). To put it simply, the system has two air intakes, and only one is opened when driving at low speed to prevent excessive fuel injection and save fuel consumption; When driving at high speed, it is all turned on, increasing the air intake to obtain more power.
Gear box technology:
CVT gearbox was first introduced by Nissan, but Nissan has been pursuing longer service life and reducing gearbox wear, coupled with conservative adjustment, which makes this CVT gearbox unable to give full play to its advantages. But the biggest advantage is that Nissan's CVT can bear more torque, even if it is a 3.5-displacement engine.
The world's three major gearboxes; Japan Aisin, Toyota Holdings 22%; German ZF gearbox, German Mercedes-Benz BMW used the most; JATCO gearbox was originally independent from Nissan's gearbox department.
It is concluded that Nissan's engine and gearbox have their own unique designs, and Nissan's pursuit direction is leather and durability, and it needs to obtain stronger power without losing fuel economy, so Nissan is still due to Honda and Toyota.
