Recently, Dongfeng Nissan's TIIDA whirlwind has blown all over the country and become the focus of consumers' attention. Why can TIIDA win the favor of consumers when oil prices soar and consumers become more rational about automobile consumption? Yesterday, Shang Cheng Nissan revealed to our reporter that besides spacious space and good power performance, the low energy consumption and low emissions of TIIDA are also important reasons why TIIDA is sought after by consumers.
Low energy consumption
TIIDA's HR 16DE engine is a low energy consumption vehicle jointly developed by Nissan and Renault. This model concentrates the scientific and technological advantages of the two major manufacturers, which not only pushes the fuel economy to a new height, but also has comfortable power. HR 16DE engine adopts aviation lightweight aluminum alloy manufacturing technology, which greatly reduces the weight. Its cylinder body adopts the low-wear true inner diameter machining technology that only racing engines have in the past, which greatly reduces the friction when the piston moves in the cylinder, reduces the loss of thermal energy output, and improves the fuel utilization rate and power output.
It is particularly worth mentioning that the brand-new aluminum alloy engine of this model adopts the continuously variable valve timing control technology of DOHC double overhead camshaft structure set CVTC, which can continuously adjust and control the camshaft phase of intake and exhaust according to the driving state of the vehicle, thus achieving excellent ignition timing, ensuring the engine to maintain the best speed at the best time, reducing unnecessary fuel consumption, and achieving the purpose of saving fuel while ensuring output power and torque.
According to Nissan sources, a few days ago, in the TIIDA "1 liter engine oil limit challenge", the champion owner actually created an amazing achievement of1liter engine oil running 26.9 kilometers. If this result is converted, the fuel consumption per 100 kilometers is only 3.72 liters, which is 2.28 liters less than the 6.0 liters announced by the manufacturer! This shows that TIIDA has excellent fuel-saving performance.
Weak emission
Today, environmental protection has become the main theme, and low-emission vehicles have emerged. Ti-TI-IDAHR 16DE all-aluminum engine has the advantages of low pollution, high combustion efficiency, and unique reverse arrangement of intake and exhaust, which shortens the distance between exhaust and three-way catalytic converter, improves the treatment effect of exhaust gas, ensures Yida's leading position in environmental protection, and its emissions meet Euro III standards, which is lower than that of some developed automobile countries.

Low fuel consumption ignites the market
Fuel consumption data per 100 kilometers Manufacturer: 5.2L
Practical: 5.6L
With the rise of oil price, economical and fuel-efficient cars have once again become a hot spot in the market. Compared with the high-profile publicity of other economical cars, Liana has the momentum of "the fragrance of wine is not afraid of the depth of the alley", which is extremely low-key. Liana series models are divided into hatchback version and sedan version. At the same time, it is divided into practical, manual standard, manual luxury, automatic standard and automatic luxury, totaling 10. In the understanding of consumers, we found that Liana's fuel economy has become its biggest selling point.
According to the person in charge of Changhe Lantian Automobile Sales & Service Company, in May, the sales volume of Liana exceeded 100. After the oil price rose, more consumers came to consult. In Changhe Lantian Automobile Sales & Service Company, we met Mr. Chen, the owner of Liana who came to do daily car maintenance. According to him, "My automatic gear Liana came home from May 1 and added 460 yuan oil, which is 100 liters of oil. The odometer shows that it has traveled 880 kilometers, and now the tank is full (50 liters). Roughly speaking, 50 liters of oil ran 880 kilometers, which is about 5.6 liters per 100 kilometers. Of these 880 kilometers, about 500 kilometers are running at high speed, and the rest are urban roads, and traffic jams are often encountered. " During the conversation, Mr. Chen also told us: "What I am most satisfied with is the fuel-saving performance of Liana. I heard that it will be more fuel-efficient after the running-in period. " Ultra-low fuel consumption, large space and the latest M 16A engine of Suzuki, Japan, are the outstanding features of the Liana series in similar models. The low fuel consumption of Suzuki engine is even more commendable. According to reports, the imported ingredients of lianas are as high as 80%. In the normal fuel consumption test of 90km/h, the fuel consumption of manual transmission is only 4.5L, and that of automatic transmission is 5.2L.

Save fuel, worry and trouble
Fuel saving data: 60-90 km/h is the most fuel efficient.
Swift has always been loved by many consumers for its fashionable appearance and fuel economy.
Among cars under 200,000 yuan, Swift has unique six airbags, ABS braking anti-lock system, EBD electronic braking force distribution system, and also adopts various folding combinations of child seat fixing devices and rear seats. These outstanding advantages are important reasons why consumers choose Swift. In addition, the application of high technology makes Swift not only save fuel, but also make car owners more worry-free.
In terms of configuration, Swift adopts the latest G series engine of Suzuki, Japan, which is made of all-aluminum alloy, which not only reduces its own weight and running noise, but also improves heat dissipation; Although the displacement is only 1.3L, the power is as high as 63KW, which is equivalent to the engine of1.6l.. Environmental protection emission conforms to Euro III standard, which is economical and energy-saving; Double ignition coils, no distributor ignition mode, more stable ignition system, low failure rate and more sufficient ignition energy. And its light and dexterous body, stable and soft power, and the myth of fuel saving at the same speed of 5 liters/100 kilometers (60 km/h) have attracted many young and fashionable consumers.
The continuous rise in oil prices makes Swift's fuel economy particularly eye-catching. Ms. Han, who has been using Swift for half a year, told reporters that Suzuki Swift is very satisfied with its beautiful appearance, comfortable ride and moderate power, and her excellent fuel-saving performance makes her feel very comfortable. Since the oil price has been raised, she has only spent about 5 yuan's fuel cost every day on average. In other words, the extra expenses incurred in one month due to the increase in fuel costs do not exceed those in 200 yuan. Compared with similar cars, the fuel economy of Swift is really enviable. In addition, Ms. Han also revealed to reporters the skills of using Swift to save fuel: ensuring the correct tire pressure, regularly checking the accuracy of the steering wheel and tires, accelerating without stepping on the accelerator, and shifting gears according to the vehicle speed. Generally speaking, the speed range of swift is 60-90 kilometers per hour.

New technology makes up for habitual loss
With the rising oil price, the fuel economy of vehicles has increasingly become the focus of market attention. Due to the differences in product concepts and production processes, products from different countries have different performances in this respect. At present, the main cars in China auto market are Japanese cars, American cars and German cars, and their economy varies greatly. So, how can we choose an economical and fuel-efficient car? The following three tricks may help you choose a car with confidence and use it easily.
As far as the appearance of a car is concerned, a small car is relatively economical. A compact car body can not only reduce the weight of the car body, but also reduce the airflow resistance during driving, thus reducing fuel consumption. Take POLO, the representative of compact car, as an example: the body lines of POLO are smooth, and the drag coefficient of the whole car is less than 0.33, reaching the highest level of hatchback. In addition, the front and rear body integrated bumpers are connected with the bumper "0 mm gap", which greatly reduces the increased fuel consumption due to air resistance. The compact body not only improves the power performance, but also minimizes the fuel consumption.
In terms of engine technology, technologically advanced engines have higher fuel economy, that is, they can output more power than ordinary engines when burning the same amount of oil, so the fuel economy is higher. POLO's valve drive mechanism adopts hydraulic bearing ball rocker arm structure. Compared with the hydraulic tappet structure adopted by most vehicles in the same class, this novel valve driving mechanism has relatively small friction torque, so it needs less driving force, which can effectively reduce engine consumption, thus reducing fuel consumption by about 3 ~ 4%. In addition, how to make the engine slim is also a direction of technological breakthrough, because it can reduce the weight of the whole vehicle.
In the handling of vehicles, driving styles and habits also have a certain relationship with the amount of fuel consumption. With the development of modern technology to a certain extent, the adjustment and standardization of driver control mode have also been realized. With the help of some electronic technologies, it can save more fuel. For example, the electronic control device E-Gas electronic throttle adopted by POLO uses advanced potentiometer to measure the angle of the driver's stepping on the accelerator pedal and transmit the information to E-Cu, so as to accurately control the throttle opening, ensure accurate fuel supply and realize economical air-fuel ratio.
Elantra 06
"I don't feel lost"
Interviewee: Wang Bo Occupation: Sales
Wang Bo is a salesman, who runs around the city all day doing sales promotion. Driving has almost become a profession. Recently, I bought a 06 new Elantra in Beijing Hyundai Sichuan Mingjia Store. After driving for a while, I have a deep understanding of how to save fuel and accumulated some experience. Now, we will sort out his experience and share it with Elantra owners.
Wang Bo said that the overall feeling of' 06 new Elantra was good. When driving on urban roads without air conditioning, the average fuel consumption is about 7.8 liters per 65,438+000 kilometers. If you turn on the air conditioner, the fuel consumption is a little more than 8 liters. My fuel-saving experience is:
1. When driving on urban roads, keep the engine speed below 3000 rpm and shift gears between 2000 and 2500 rpm, which can not only ensure abundant power, but also control fuel consumption.
Second, because the 06 new Elantra is equipped with an 82kW engine, the power is very good. If you step on the accelerator lightly and add a little oil, the car will leap forward. Therefore, driving in the city, especially in the initial state, must be well grasped. Don't refuel violently during the whole driving process, you can keep driving at a constant speed.
Third, insist on checking the tire pressure once a week, and it must be checked once every two weeks at the longest. Keeping the tire pressure in a normal state is also an effective way to save fuel consumption.
Fourth, whether driving inside or outside the city, it is best not to exceed 120 yards per hour. Because in this state, you can hardly feel the loss of strength. Wang Bo was deeply touched by this. He said that he once saw someone on the Internet saying that the Elantra manual transmission used high fuel consumption, 1 1 fuel increase/100 kilometers, and he once went racing with his companions, and the fastest speed reached 160 kilometers per hour. The engine speed is about 4000 rpm, and the fuel consumption is only a little more than 9 liters.

High displacement does not mean high fuel consumption.
The price of oil has gone up again, and consumers will inevitably have to pay the "oil" bill when buying a car. However, in real life, large displacement and high fuel consumption are not necessarily equal. Many people disagree with this statement. The fuel-saving performance of Huapu marine horse series, which was reflected by the owner Chen to this newspaper not long ago, gave a good proof to the reporter.
Mr. Chen told the reporter that in the second half of last year, he bought a Huapu Haishang MA 1.8L sedan at Huapu Automobile in Tongan, Sichuan. Because the oil price was relatively low at that time, he didn't care too much about the displacement of the car. He just thought that Haishang MA 1.8L was beautiful in appearance, spacious in interior and comfortable to drive, so he bought it. To Mr. Chen's surprise, although the displacement of Haishang MA 1.8L is 1.8, the actual fuel consumption is quite low, and its fuel saving performance can be said to be quite excellent in similar vehicles. Under normal circumstances, the fuel consumption per 100 kilometers is about 6 liters. Even if the air conditioner is turned on in summer, the actual fuel consumption is only 7.5 liters, which is obviously inconsistent with the displacement. For this unexpected harvest, Mr. Chen is extremely happy, especially today when oil prices are rising frequently.
In order to know more about Haishang MA 1.8L's unique skill in fuel saving, the reporter interviewed Mr. Zhangfan, a technical expert from Tongan Huapu. Teacher Zhang believes that the reason why Huapu Haishang MA 1.8L has good fuel economy should be analyzed from two aspects: internal and external factors. There are two internal reasons. Firstly, the latest multi-point electronic fuel sequential injection engine intelligent management system (M7) is adopted. Second, the body design is unique, and the drag coefficient is only 0.32, thus realizing the power of 1.8L and the fuel consumption of1.3l.. The external cause is to accumulate practical driving experience according to the actual characteristics of Haishang. For example, start lightly, step on the accelerator lightly, and usually run at a speed of 60 ~ 80 km/h. In addition, it is also very helpful to do maintenance as required.

It is more thorough to choose dual fuel to save fuel
"The price of gasoline has gone up again, so I'd better change my car to one that burns gasoline." This is probably the most frequently said by car owners after the price of gasoline has been raised again in the past two weeks. Changing gasoline vehicles to natural gas vehicles is often just a lot of people's talk, and it may be rarely put into practice. However, during this period, the sales of dual-fuel vehicles became more and more popular. What makes the sales of dual-fuel vehicles so hot? The dealer told the reporter that economy, safety and comfort are the keys for consumers to choose this car.
Representative model Elysee dual-fuel automobile
★ More economical-when using natural gas, the cost is saved by 30%-35% compared with using gasoline, which not only saves the fuel cost, but also saves the maintenance cost and prolongs the service life of the engine;
★ More stable-equipped with Italy's advanced imported natural gas system, which improves the matching problem between natural gas and the original engine and avoids the occurrence of engine backfire;
★ More convenient-equipped with 65L ultra-large capacity gas cylinders, compared with ordinary 45-55L gas cylinders, the driving mileage can be increased by 50-60 kilometers at a time, the gas filling times can be reduced, and the driving range can be improved;
★ More environmentally friendly-compared with gasoline, the use of natural gas can comprehensively reduce the emission of tail gas pollutants by 82.2%, and the HC, CO and lead compounds in its emissions can be reduced by about 70%, 90% and100% respectively;
★ More reliable-dealers began to actively promote Dongfeng Citroen dual-fuel vehicles many years ago. In Beijing, Chengdu and other places, they have tens of thousands of cars, of which nearly 7,000 are CNG products on the market. As the vehicle technology is mature and the quality, safety and service guarantee are in place, users are more assured. As a region rich in gas and poor in oil, Sichuan has more than 60 natural gas filling stations around Chengdu, and more stations are under construction, making it very convenient for car owners to refuel.
