When Putin rose, he simply took off his shirt and went fishing naked.

President Putin strolled along the Yenisei River.

　　　　Guangzhou Daily reported on August 24th that when Russian President Vladimir Putin showed off the diplomatic and military "muscles" of great powers, he was undoubtedly always able to impress the whole world. But perhaps few people can think that Putin can stimulate a large number of eyeballs when he reveals his real muscles. The photos he took topless during his vacation in Siberia last week are still talked about by many Russians.

　　　　The president undressed.

　　　　During his vacation in Siberia with Prince Albert II, head of state of Monaco, from August 13th to 15th, Putin showed the little-known side of the Russian leader.

　　　　Putin changed his formal attire of suit and tie, put on sunglasses, sun hat and jeans, and accompanied Prince Albert II to travel around the cultural and natural scenery of the Republic of Tuva. Riding a rubber raft on the Yenisei River, driving an off-road vehicle for a ride on the mountain road and riding a fine horse on the grassland, Putin is quite cowboy.

　　　　On the banks of Yenisei River, when Putin rose, he simply took off his coat, swung his rod naked and fished, so that his strong body could get in close contact with nature.

　　　　Photographers certainly can’t miss this wonderful shot, and Putin’s semi-nude photos immediately appeared in many newspapers, televisions and websites. The Kremlin also published a set of photos taken by Putin during his vacation on the official website, including a photo of Putin walking naked by the river.

　　　　People are hotly discussing

　　　　Putin’s half-naked appearance for a week has been hotly debated in the streets, newspapers, websites, radio and television, and many women in Russia have even praised the body of the 54-year-old national leader.

　　　　The Communist Youth League Pravda, one of the largest newspapers in Russia, reported that since the newspaper published Putin’s semi-nude photos, a large number of netizens have posted messages on their websites, commenting on Putin’s "robust body", among which many female netizens "exclaimed with joy and did not hesitate to praise".

　　　　Evgeniya Albat, the host of the radio program, was criticized by many female listeners for commenting that the semi-nude photos were inconsistent with Putin’s status as President. Many female listeners also sent her emails to express their appreciation for Putin’s strong body.

　　　　The Communist Youth League Pravda also published a report entitled "Get a Body Like Putin" on the 22nd, in which a fitness instructor described in detail how to exercise a strong body like Putin. On a semi-naked picture of Putin published in the essay, the editor also specially marked the main muscle groups on Putin with arrows.

　　　　For the photo of Putin riding a horse in a tight white shirt, the report said: "The outline (muscle) under the shirt is very clear."

　　　　Sports "cool" will

　　　　Although he is over half a year old, Putin still maintains a strong body, which is not unrelated to his love of sports.

　　　　Putin loves judo very much, and has been practicing it since he was a child. At the age of 18, he has become a master of black belt. He is also a master of Sambo wrestling. He was awarded the title of "Sportsman" in Sambo wrestling and was elected honorary president of the International Amateur Sambo Wrestling Federation in 2005. He also often swims and likes skiing.

　　　　In Russia, where athletes come forth in large numbers, sports are not only helpful for Putin to keep fit. He once said in an interview: "Sports help me form an understanding of the world, people and people."

　　　　"He is cool," said Sergei Markov, director of the Russian Institute of Political Studies. "This is his image during his presidency-cool."

With Xia Yiping, CEO of Extreme Yue Automobile, acknowledging the financial problems faced by the company at an internal meeting, and the divestment of Baidu, the future of Extreme Yue seems to have been doomed. Many 4s stores are closed, and the delivery of new cars is delayed. It seems that it is only a matter of time before they fall down.

Xia Yiping, CEO surrounded by employees from Vietnam.

It is definitely not the first brand to fall, and it may not be the last one. In those days, "a hundred schools of thought contend" are few and far between. Let’s review the development history of new energy in China and see which brands have fallen on the road of overtaking in new energy corners.

The first bankrupt new energy brand: Yangtze River

Maybe you’ve never heard its name. But the Yangtze River car was still very serious. Full name of Changjiang Automobile: Hangzhou Changjiang Automobile Holding Co., Ltd. It used to be Hangzhou Bus Factory in 1954. They are one of the largest and earliest manufacturing bases of trams and their special chassis in China. In 2013, Li Ka-shing invested 5.1 billion yuan in Wulong electric vehicle, and the Yangtze River new energy vehicle was born.

As a brand that bought new energy roads very early in China, Changjiang set up companies and factories in Guizhou, Shenzhen, Chengdu and other regions in the early days of its establishment. In just three years, Changjiang Automobile launched four models, including Yiku, Yige, Yisheng and Yizhong. However, sales were less than expected, and new energy subsidies declined. In 2020, Changjiang New Energy Vehicle declared bankruptcy.

The most concerned new bankruptcy energy: Weimar

Weimar, as a frequent visitor to CCTV, had a good strength. Among the four brands of the former new forces, in addition to "Wei Xiaoli", there is Weimar. Weimar, established in 2015, has won the champion of bicycle sales of new forces, and even sold better than Wei Xiaoli. In 2020, Weimar’s cumulative sales volume exceeded 20,000 units, ranking fourth among the new forces in the country. Intelligent driving is also the key technology that Weimar has been working hard to study.

However, since 2022, Weimar has heard many negative news, such as salary reduction, rent arrears, and dealers quitting the network. Although Baidu, Tencent, Shanghai State-owned Investment Platform, SAIC, Sequoia China, hongta group and other groups jointly raised more than 35 billion yuan for Weimar, it did not change the ending of Weimar’s decline. Weimar filed for bankruptcy in 2023, and 110,000 Weimar owners still face after-sales problems.

New energy blackened by charging piles: land ark

Although you should not have heard of this brand, as a regular car company with a total investment of 10 billion yuan, it has gone from "Laotoule" to qualified production in just five years, and Land Ark is really capable. Its branches are also spread all over Beijing, Shenzhen, Shanghai, Foshan, Jiangsu and other places, and there is also a look of recruiting talents. However, in July 2018, a land ark in Shui Mu Huacheng Universiade charging station spontaneously ignited, which should be the first time that ordinary consumers have paid attention to the spontaneous combustion of new energy on a large scale since records began.

Since then, the land ark has been frequently and naturally blacklisted by many charging pile companies, coupled with the subsidy policy, and finally declared bankruptcy in 2021.

The worst new energy cheated: Jiangsu Sailin

An American lawyer with a Chinese face, in the name of building a car, cheated 5.6 billion and walked away. He is still at large, and the initiator is almost a white wolf with empty gloves. This is the story of Wang Xiaolin and Jiangsu Sai Lin.

There is a racing driver named Steve Saleen in the United States, who once set a world record for the speed of cars and founded his own sports car brand. However, due to poor management, it was closed down, and finally a man named Wang Xiaolin bought its right to use in China for 500,000 dollars. After that, Wang Xiaolin first talked about cooperation with the Ordos municipal government, but Hubei felt that this matter was not reliable and gave up. Later, Changsha also entered the negotiation table, but it was cancelled after a year of cooperation.

Finally, Wang Xiaolin found the Rugao municipal government in Jiangsu Province. At this time, the largest new energy automobile base in Jiangsu was completed, and there was a demand for performance, so the negotiations with Wang Xiaolin were extremely smooth. In addition, the launch conference of Sai Lin Bird’s Nest, which cost 300 million yuan, included Jason Statham, Wu Yifan, American Top Gear host Tanner Foust and many other stars. With a wave of his hand, major banks allocated Wang Xiaolin a loan of 2.3 billion yuan. In this way, Wang Xiaolin fled to the United States with huge sums of money and is still at large. Jiangsu Sailin, on the other hand, only produced such an electric car similar to "Old Man Le", which was more expensive than Song Plus DM-I..

Regardless of the success of overtaking in corners, there are 8 companies that have fallen on the road without 10. The icons that have been lit are also dimmed one by one, which is the cruelty of market competition. So who do you think will be the next new energy vehicle company to close down?

From the point of view of sliding back, it incorporates many sharp design elements. Generally speaking, the front face of the new generation of escaping cars has become more atmospheric, and some protruding lines have been added to the hood, which looks quite muscular. The headlights on both sides are sharp, and the internal light groups are patchwork, which makes them bright when lit. From the side of the car body, the new car still has smooth lines with a sense of design, and the tradition of wide C-pillar can be continued. In addition, it is equipped with a 16-inch multi-frame wheel body to make it more sporty. In the design of the smooth tail of the line, this model has shaped the posture of movement, and the design of the taillight shape is also interesting, which is very personalized after lighting.

In the interior of this car, Yidong emphasizes simplicity and luxury. The new car is also equipped with three models of the latest style of Changan Automobile, which makes people feel full of power when driving. The central control is made of soft plastic, and the materials and workmanship look quite satisfactory. It is equipped with a 7.0-inch LCD instrument panel to control the LCD screen, which shows clearly and the design is relatively standard in the whole system. The front row is also equipped with a manual air conditioning control system to freely debug the most comfortable space atmosphere. .

The length, width and height are 4770×1840×1440mm respectively, and the wheelbase has reached 2765 mm. In the same class, the wheelbase of Yidong ranks fourth. The interior space of the car is relatively spacious at the same level, the height and width of the car are ideal, and the legroom in the back row will not feel cramped, which belongs to the upper-middle level at the same level. The escape 1.5T GDI double clutch flagship skylight provides a wider field of vision, which can create a better visual environment and good sensitivity for the rear passengers and increase the light entrance for the whole vehicle. Among the models of the same price and class, Yidong’s trunk volume ranks eighth. The space is relatively regular, without obvious protrusions, and the overall loading capacity is good.

Yidong 1.5T GDI dual clutch flagship adopts 1.5 engine, with maximum horsepower of 170 and peak torque of 260, matching with wet dual clutch (DCT) gearbox. It will definitely bring unforgettable control charm. Ranked 16th among 80,000-120,000 compact car models.

The active/passive safety configuration of Yidong is complete, includingAutomatic parking、Zero tire pressure endurance tire、Automatic parking、Steep slope descent、hill start assist control、knee airbag、HUD head-up display、Anti-lock braking (ABS)、Braking force distribution (EBD/CBC, etc.)、Brake assist (EBA/BAS, etc.)、Traction control (ASR/TCS, etc.)、Active noise reduction、Engine start and stop、Side safety air curtain、Wireless charging of mobile phone、night vision system、LED daytime running lights、Forward reversing radar、Tire pressure monitoring、Steering wheel heating、Body stability control (ESP/DSC, etc.)、Rear reversing radar、Fatigue reminder、Remote parking、Child seat interface、Lane keeping (LKAS)Equal configuration.

Among them,Automatic parkingYou can avoid stepping on the brakes for a long time or needing to pull frequently;Steep slope descentCan safely pass through steep slope road conditions at low speed;knee airbagReduce the injury of the car interior to the occupant’s knees in the secondary collision.

　　[car home Engine Disassembly] Engine energy saving and emission reduction is the general trend. In order to comply with the trend, major automobile manufacturers around the world have introduced small-displacement turbocharged engines to win market opportunities. American manufacturers, who have always been regarded as keen on large-displacement engines, have also actively carried out research and development of small-displacement turbocharged engines in recent years. Ford is one of them, and its latest 1.5T EcoBoost engine (hereinafter referred to as "Ford 1.5T engine") is the first to be installed on the 2013 Changan Ford Mondeo. After the launch of Changan Ford Mondeo, the 1.5T engine was also mounted on the main models of Changan Ford such as Maverick, Focus and Taurus. What we are going to dismantle today is this Ford 1.5T small-displacement turbocharged in-cylinder direct injection engine. What kind of characteristics does it have? Let’s find out by disassembling it.

Low Ford 1.5T engine of those things.

　　European emission regulations have always been very strict, forcing manufacturers to improve their engine design to reduce emissions. Therefore, Ford European technical team has more mature experience in developing low-emission engines. The 1.5T engine to be dismantled today is a small-displacement turbocharged direct injection engine designed by Ford European technical team.

　　This Ford 1.5T engine is a global engine product, which means that its emission level can meet the emission targets of all countries in the world. When the engine is put into a specific market, it must be adjusted domestically to meet the local use environment. China has a vast territory, a large latitude span, and a large altitude difference and temperature difference. The engine engineer in charge of domestic adjustment must go to cold yakeshi, hot Hainan and the Qinghai-Tibet Plateau with thin air to adjust the parameters of the engine management system accordingly, so as to ensure that the engine can work efficiently and stably anywhere in China.

　　The 1.6T engine is equipped with an external air-cooled intercooler, and the exhaust manifold is not integrated in the cylinder head. The 1.5T engine is more mainstream in configuration, adopting water-cooled intercooler integrated in the intake manifold and integrating the exhaust manifold into the cylinder head. This Ford 1.5T engine can be regarded as an improved model of 1.6T, adopting more mainstream technologies.

　　The 1.5T engine reduces the displacement by 0.1L, but the power is increasing (the maximum power is increased by 4 HP, and the peak torque value remains unchanged). In China, the consumption tax on vehicles with 1.5T engines is 3%, while the consumption tax on vehicles with 1.6T engines is 5%. Without the 2% tax saved by 0.1L displacement, the Ford model with 1.5T engine has higher flexibility in pricing, which is conducive to improving the competitiveness of the model. It can be seen that Ford has already considered China’s tax policy when planning the engine product. (Vehicle consumption tax is included in the vehicle price and paid by the vehicle enterprise to the state)

　　Ford didn’t follow the Volkswagen who pushed the dual clutch. The 1.5T engine was matched with a 6-speed automatic gearbox, which is what I like to see. After all, with more products, consumers have more choices. Moreover, the performance and transmission efficiency of the mainstream 6-speed automatic gearbox are not low, and it has a good performance in shifting smoothness and durability, which is a recommended configuration.

　　　In the same class with Ford 1.5T engine, there are not a few models with 1.4T, 1.5T and 1.6T engines. General 1.5T engine and Ford 1.5T engine are in direct competition because of their close displacement, while Volkswagen 1.4T engine and Citroen 1.6T engine are also two powerful competitors.

　　Ford 1.5T engine is more focused on power output. Compared with other manufacturers’ 1.4T, 1.5T and 1.6T engines, the power output of this engine has obvious advantages. In terms of torque output, the torque output of Ford 1.5T engine meets the standard of mainstream 1.5T engine.

　　The 1.5T engine mounted on Changan Ford is produced by Changan Ford Motor Co., Ltd.. The engine we disassembled this time is a teaching prototype, and some parts are slightly different from the mass production model. Before it’s too late, let’s completely disassemble this engine!

● Overhead direct injection system

　　Ford 1.5T engine adopts overhead in-cylinder direct injection system, and the high-pressure gasoline nozzle is located at the top of the combustion chamber. Unlike the side nozzle, the overhead nozzle will not spray gasoline on the cylinder wall, thus avoiding the "wet wall phenomenon". Wet wall phenomenon will lead to engine oil dilution, fuel economy decline and emission increase.

● Turbocharging system

　　The turbocharger used in Ford’s 1.5T engine is provided by Borg Warner, and the maximum speed can reach 150,000 rpm. The maximum pressurization pressure of the turbocharging system of the engine can reach 1.5Bar. Like Volkswagen 1.4TSI engine and general 1.4T engine, this engine adopts an integrated exhaust manifold which can improve the thermal efficiency of the engine.

　　Compared with the turbocharging system, the overhead direct injection system of Ford 1.5T engine has more "gold content". Geometric modeling of piston crown, angle of oil jet from nozzle, position of spark plug, organization of intake and exhaust airflow and later verification of combustion system all need a lot of time and rich experience.

● Variable intake and exhaust valve timing system

　　The advantage of variable intake and exhaust valve timing technology is that the combustion exhaust gas can be removed from the cylinder by fresh air through the overlapping angle of intake and exhaust valves with a large angle to improve combustion efficiency and power output. The application of large-angle overlap angle of intake and exhaust valves in manifold injection engine may lead to the waste of fuel and increase fuel consumption. However, the in-cylinder direct injection engine does not have the above concerns, and can control the fuel injection timing and not inject fuel during scavenging, so that the gas used for scavenging is fresh compressed air without gasoline, and the fuel consumption is not increased while the combustion exhaust gas is removed. This is also one of the reasons why the mainstream direct injection engine is fuel-efficient now.

● Valve drive structure with simple structure

　　Ford 1.5T engine does not adopt roller rocker valve drive structure with complicated structure but lower friction coefficient, but adopts valve top cylinder drive structure with relatively simple structure. However, through the optimization design of camshaft, this valve drive system effectively meets the corresponding design objectives and realizes the balance between cost and benefit.

　　The use of timing belt is beneficial to reduce engine noise. The engine adopts a simple top cylinder valve drive structure, but some designs are adopted on the cam and valve seat ring to reduce friction and improve durability. The adoption of variable intake and exhaust valve timing system enables the engine to flexibly control the overlap angle of intake and exhaust valves, which makes the engine exhaust more smoothly under high load, and at the same time, the fresh air entering from the intake valve can completely "clean" the exhaust gas in the cylinder, which improves the efficiency of the engine.

● Reinforcing structure of cylinder block/cylinder head

　　Some structural designs are adopted on Ford 1.5T engine to strengthen the strength of cylinder block. The improvement of the overall strength of the engine not only improves the service life of the engine, but also has certain benefits for the NVH characteristics of the engine.

● Unique coolant tank, cylinder net pattern and oil nozzle.

　　In addition to the above-mentioned cylinder reinforcement structure, the cylinder of Ford 1.5T engine has more unique designs, and the shallow groove between the cylinders is one of them.

● Integrated intercooler

　　　The first step of engine operation is to inhale air from the environment, and for turbocharged engines, the air from the environment will be turbocharged first, and then it will be sent to the cylinder after the air pressure is increased. The blades on the turbine compressor do work on the air, which will increase the air temperature. In order to further improve the density of compressed air, increase the amount of oxygen entering the cylinder and increase the output power of the engine, there will be a device called "intercooler" in the intake system of turbocharged engine, and its function is to cool the pressurized air. According to statistics, under the same air-fuel ratio, the engine power can be increased by 3% ~ 5% for every 10 degrees Celsius drop in the temperature of pressurized air.

　　A large number of reinforcing structures are adopted on the cylinder head and cylinder block of Ford 1.5T engine to enhance the overall strength of the engine. However, the coolant tank between the cylinders and the crankshaft bearing cover bracket are very special, which are rare in other engines of the same class.

● Vacuum pressure storage tank for start-stop system.

　　We saw a box as shown above the intake manifold of Ford 1.5T engine. This box is actually a vacuum pressure storage tank, which is connected with a vacuum pump to store the negative pressure required by the brake booster pump. Then why do other models rarely see this device?

● Mechanical variable displacement oil pump

　　Ford 1.5T engine uses a mechanical variable displacement oil pump, which realizes two-stage variable displacement through internal mechanical structure. At low speed, the displacement of oil pump is kept at a low level to reduce power loss; At the middle and high speed, the displacement of the oil pump reaches the maximum, providing sufficient lubrication for each friction pair of the engine.

● Breaking connecting rod and casting crankshaft.

　　Like the engines of many mainstream joint ventures that we have dismantled, the Ford 1.5T engine uses a high-cost expansion-breaking connecting rod. The crankshaft is made of cast crankshaft, and in order to realize light weight, only four balance weights are designed.

Full text summary:

　　This 1.5T engine, developed by Ford’s European team, has undergone various bench tests and hundreds of thousands of kilometers of road tests before it is put into production in China, which ensures the high stability of the engine in extreme use environments such as high temperature, cold and high altitude, so as to meet the complex vehicle environment in China. Matching with this Ford 1.5T engine is a 6-speed automatic gearbox, which has a good performance in shifting smoothness and durability, and also meets the higher requirements of China consumers on comfort and product durability.
