How about vvti engine

1The Trade data-driven investment strategiesadvantage of the VVTi engine is that it can change the cylinder diameter of the engine under different operating conditions, so as to improve the engine performance. The VVTi engine can adjust the cylinder diameter of the engine according to the driver's driving habits and environmental conditions, and can obtain higher power even under low fuel consumption, thus saving fuel.

2. Therefore, vehicles using VVTI technology are not only more fuel-efficient, but also have much better power performance than vehicles that do not use VVTI technology. There are three major factors in whether the vehicle is fuel-efficient. The displacement of the engine, the larger the displacement, the more fuel it costs. What about the engine intake system? The simpler the intake system, the more fuel the vehicle will be.

3. Toyota Vechi adopts 5L and 3L self-aspirated engines, and the high-configuration version is matched with 8-speed stepless transmission.Box, the low-configuration version is matched with a 5-speed manual transmission. The Vechi engine applies Toyota's latest power technology VVTI, which has the characteristics of variable gas timing, with a maximum power of 81kw, a maximum torque of 138Nm, and a maximum speed of 180km/h.

4. This is a 5-liter VVTi engine with advanced European technology, with strong and stable performance, fuel economy, stable and reliable, more comfortable and safer driving.

5. [Pacific Automobile Network] VVTI is the English abbreviation of Toyota's intelligent variable valve timing system. According to the operation of the engine, the amount of air intake (outhaust) and the valve opening and closing time and angle are adjusted to optimize the amount of air entering and improve combustion efficiency.

6. Automobile engine DVVT, CVWhat does VT mean? Engine proprietary technology, Honda's VTEC, Toyota's VVT-i, Hyundai's CVVT, Mitsubishi's MIVEC and BMW's D-VANOS will all come to mind, among which Honda's VTEC and BMW's D-VANOS were the most famous pioneering technologies at that time. Honda is famous for its VTEC.

Excellent car engines in Germany?? Or is the Japanese car engine excellent??

1. Japanese engines are characterized by high thermal efficiency of self-aspirated engines, relatively stable, fuel-efficient, and relatively strong linearity of power output, but the torque of Japanese engines is relatively low, and the sense of acceleration is not very strong.

2. Secondly, German engines are relatively excellent in quality and are representative manufacturers in the automobile industry. Most German engines are made of cast iron materials, which have strong pressure resistance and corrosion resistance. Japanese engines are more sophisticated and pay attention to the optimization of details. Most of the engine materials are aluminum alloy, which is relatively light in weight, but it is easy to be damaged under this premise.

3. At present, both German and Japanese cars are sold well, so the engines of German and Japanese cars are always good for that one, and the service life of that one is longer. The representative of Germany is generally Volkswagen, and the representative of Japan is generally Toyota. There is no other way. Volkswagen and Toyota are the best-selling cars in the world.

Japanese automobile enterprises, which company's engine is the best?

In Europe and the United States, Honda has long occupied the title of "the most reliable car brand". A long time ago, a Honda Accord produced in the United States in 1996 set a world record of 1 million miles without overhaul, which shows the reliability of the Honda engine.

There is no doubt that the top three Japanese companies are Honda, Toyota and Nissan. RankThe sales volume of the top three Japanese companies has risen steadily, occupying half of the car sales list, which frightens Mazda, which ranks fourth. The sales volume of the top three companies in Japan is closely related to the reliability and durability of the engine.

Japanese cars Honda, which has the best engine in enterprises, is not only famous in Japan, but also in the world. Chinese car enthusiasts jokingly call "buy an engine and get a free car" and "Honda Black Technology" both refer to Honda's engine. The core technology is VTEC technology, which has the characteristics of fuel saving and large power output.

NO Daimler Award-winning engine: 0T in-line six-cylinder engine + 48V light hybrid system The second is Daimler, which is the parent company of Mercedes-Benz, and the shares purchased by Geely some time ago are Daimler's.

Toyota Good Quality Toyota Corporation owns five of the world's top 500 enterprises, namely Toyota Motor Company Japan Aisin Precision Machinery Co., Ltd. AISIN Japan Denso DENSO Japan Toyota Automatic Loom Company Toyota Trading Co., Ltd. More than a dozen first-class enterprises of the consortium are all world-renowned enterprises. The industrial chain covers the automobile industry.

The best are German cars and Japanese cars. It is undeniable that the Germans and Japanese people in these two countries are very meticulous in their work and pay attention to excellence in the technical field. In the manufacturing industry, especially in the automobile field, their competition is also very fierce. According to the current market data, Japan's Toyota's sales volume ranks first in the world.

Why Japanese enginesChinese experts can't make it

1. This mainly depends on the design and manufacturing technology of the engine, and whether China has enough technical resources and manufacturing capacity to realize these technologies. Japan has rich experience and advanced technology in engine manufacturing, especially in certain types of engines, such as hybrid engines and turbocharged engines.

2. Some people say that the excellent skills of Japanese initiators are complained in the global market, while Chinese cars started late, and it was rare to achieve the usual level. Although the performance of Chinese car launchers is not as good as that of Japan, it was enough to meet daily needs.

3. Of course, the reason is far from that. Objectively speaking, Japan is at the forefront of the world in the field of precision machine tools. Even if you tell other countries that other countries are not good enough in the field of precision machine tools, you can't do it.

4. This is also the reason why the performance of the Nissan engine will decline after it is reassembled. Although China started late in this field, it has gradually developed into the country with the largest industrial output value. I believe that in the near future, China will definitely make great achievements in the field of engine manufacturing.

5. When it comes to which country is the most developed in science and technology at present, Lao Wang thinks that it is not the United States, not Germany, but Japan. The Japanese are very good at mechanical and electronic manufacturing technology, especially Japanese engines. That's why Japanese cars are fuel-efficient and durable. The main reason is that they have A highly technological engine.

6. In terms of public basic technology, it can be learned and easy to plagiarize, but in engine high thermal efficiency combustion, material manufacturing, vehicle design, silence...It is impossible to copy in other aspects.

How about the Dongfeng Nissan 1.6 engine

The Dongfeng Nissan Sunshine 6L naturally aspirated engine adopts 16-ell valve technology, which has good fuel economy and starting performance, strong power output, and the maximum The power is 86Kw, and the maximum torque is 158N·m, which can meet the needs of high-speed urban driving.

The 6L engine of Dongfeng Nissan Sunshine has excellent emission performance under the national six emission standards, which is very much in line with environmental protection requirements and can better protect the environment.

Dongfeng M5 is a car launched by Dongfeng Nissan Motor Company. It is equipped with a 6L naturally aspirated engine and a dual-clutch gearbox, which is more in line with the current situation of energy saving and emission reduction, with excellent performance and strong reliability.

Dongfeng Nissan Xuanyi is equipped with a 6L engine with a variable valve timing system, which has strong power performance. Its maximum power can reach 110 horsepower, and its maximum torque can reach 154 Nm, which can meet the driving needs of consumers.

The displacement of Sylphy is good, with a maximum power of 126 horsepower and a maximum torque of 154N/m, which is very suitable for home use and has good comprehensive performance. In terms of power, the new Sylphy will continue the powertrain of the old model, providing 6L and 8L naturally aspirated engines.

Oil sludge is generated in the lubrication system, and the oil sludge blocks the oil return hole of the oil ring and weakens the oil scraping performance. There is wear between the piston and the cylinder wall. The valve seal is corrosion-aging and the sealing performance is invalid. In addition, there is a crankcase ventilation system (exhaust valve) in the car now. If there is a problem, it will also increase the consumption of oil.
