The shape of the lower enclosure has also been adjusted, with large diversion grooves on both sides, and chrome-plated strips inside to create a fangs shape, which effectively increases the sense of grade; Trapezoidal air intake is used in the middle part, and black decorative strips are used at the edge to create a fangs shape, which makes the style look fierce.

There is no change in the side shape, the roof has a little slip-back lines, and chrome-plated strips are added around the window and the side skirt, which effectively increases the sense of grade; The waistline adopts a penetrating design, which makes the visual effect look slender and atmospheric, and at the same time enhances the layering of the side of the car body; The shape of the hub has also changed slightly, and the five-spoke two-color shape has been adopted, which makes the style quite fashionable.

In terms of tail modeling, the top of the trunk is designed with a slightly upturned duckling tail. The real shot model was camouflaged by the 4S shop, and the highlight chrome strips of the penetrating taillights on both sides were replaced by LED strip, creating a penetrating taillight group modeling, effectively stretching the lateral visual width of the tail; The shape of the lower enclosing part is radical, equipped with diffuser, and the exhaust pipe adopts the layout of two outlets on both sides.

In terms of size, the length, width and height of the 2023 Geely Xingrui are 4785/1869/1469mm and the wheelbase is 2800 mm. It is positioned as a compact car.

In terms of configuration, the 2023 Geely Xingrui comes standard with reversing radar, reversing image, cruise control, tire pressure display, automatic parking, uphill assist, keyless entry, one-button start, electric adjustment of main driver’s seat, automatic LED headlights and automatic air conditioning; Except for the lowest model, all other models are equipped with rear air conditioning outlets.

In terms of space, thanks to the wheelbase of 2800mm, the rear legroom performance of the 2023 Geely Xingrui is also excellent. The passenger with a height of 1.7 meters is close to 3 punches in the rear legroom, which is no problem for daily use; The uplift of the central platform is not large, which will not affect the comfort of passengers in the middle position.

In terms of power, the 2023 Geely Xingrui is equipped with a 2.0T engine, with a maximum power of 190 HP and a peak torque of 300 N m. It is matched with a 7-speed wet dual-clutch gearbox, with an acceleration time of 7.9 seconds per 100 kilometers and a comprehensive fuel consumption of 6.7L/100km under NEDC conditions.

On the whole, the 2023 Geely Xingrui is indeed a model with strong comprehensive competitiveness, with a stable and atmospheric appearance, a sense of science and technology in the interior, and excellent power and space performance at the same level. If the budget is less than 150,000 and you plan to buy a large-space car, the 2023 Geely Xingrui is worth considering.

Let’s take the Peugeot Citroen 1.6T engine, which has the largest inventory at present, as an example. The valve cover is damaged from 70,000 km to 100,000 km, which is not a common problem of Peugeot Citroen. BMW, Buick, Chevrolet, Ford and other models are also prone to oil leakage when driving for 100,000 kilometers, or the negative pressure is wrong, and the air intake fault is reported, or there is a fire, or the oil consumption is obviously abnormal.

Distinguishing between true and false valve cover

First, the original valve cover must be used. Replacing the original valve cover will solve the problem. The original Peugeot Citroen valve chamber is produced by Meijia, and there are many parallel imports in the market, and 95% of the quality is very poor. If there is no reliable channel to purchase, the probability of buying parallel valve chamber covers is as high as 95%. Once the valve cover of parallel imports is used, it is highly probable that it will not work well, and there are still many potential safety hazards, such as the engine idling for one hour, the engine climbing up a steep slope and stepping on the accelerator, and when the negative pressure inside is high, the engine oil will leak from the valve cover pad. In severe cases, there is too much engine oil in the engine room, which flows to the exhaust manifold below. Under the high temperature of the exhaust manifold above 400 degrees, it is easy to cause the engine to catch fire, and the potential safety hazard is great.

Someone replaced the aluminum alloy cover. The aluminum alloy cover is not the original one, which is not easy to use, because when the valve cover is installed, the plastic one has tension, and the aluminum alloy has no tension at all, which will lead to oil leakage after a period of use. Of course, if the original factory is aluminum alloy, we must change the original aluminum alloy cover, and if the original factory is plastic, we must change the original plastic cover.

Second, how to identify the original valve cover. It is very difficult to tell the difference just by looking at the valve cover. Look at the picture below: The red spots in the aging and damaged valve cover have been damaged and fallen off, resulting in serious engine oil burning.

How can two new valve covers distinguish between good and bad? The simplest way is to compare the gluing at the seams. Figure 1 shows the gluing seams of brand parts, and Figure 2 shows the seams of the original Meijia. The glue in the joint position in Figure 1 is rough, which can be seen by naked eyes. The glue in the original factory of Figure 2 is uniform and tidy.

The glue applied to the seal under the oil cover, Figure 3 shows the glue of brand parts, and Figure 4 shows the glue of the original valve cover, which is also very different. So if you want to change it, just change the original parts.

Third, matters needing attention in replacing the 1.6T valve cover. Many riders have encountered the problem of oil leakage from the valve cover or oil burning due to the aging of the one-way valve in the valve cover, and the problem has not been solved after replacement. In fact, there are three reasons. Remember the following three points, and it is not a detour to replace the valve cover.

Fourth, the negative pressure value that everyone pays the most attention to. Many people are unfamiliar with the negative pressure of the 1.6T engine. Today, we will provide this value for you to facilitate the inspection of engine oil in the future.

First of all, there must be a tool to test the negative pressure value. After the hot car is started, the negative pressure value is detected. One end of the hose is inserted into the filler of the oil dipstick, and the other end is set to mbar, so that the test can be started. The normal value of 1.6T has a slight change around 35. If it is lower than 25, it will obviously start to consume oil. At this time, it is impossible to observe it by using the traditional method to open the oil cover and pull out the oil dipstick, which can almost approach the oil consumption of 3000-4000 kilometers per liter. If it is lower than 12, there will be obvious abnormal consumption of engine oil, and it is common to consume one liter of engine oil for hundreds of kilometers or one thousand kilometers. Especially in the early aging of the valve cover, the oil consumption of low-speed driving in the city is not obvious, and the oil consumption of high-speed driving will be significantly higher.

Precautions for valve cover replacement

First, the original valve cover, which is an essential element;

Second, after disassembling the valve cover, the cooling time should be sufficient;

Third, install the screws in sequence according to the standard torque.

As long as we pay attention to the above three points, we can solve the problem well, and the valve cover problem is not a design defect.

summary

With regard to the problem of burning engine oil caused by the valve cover of French vehicles, we should pay attention to two points: first, replace the original valve cover; Second, find professional checkpoints, such as legal system specialization and sunshine craftsman shop. The burning oil caused by the valve cover can be 4000 liters or 600 liters, which is possible. In the initial stage, it is not serious to consume one liter of engine oil for 4000 kilometers, and it will consume one liter of engine oil for 1000 kilometers or hundreds of kilometers in the later stage. To prevent the engine from burning engine oil prematurely, we can regularly use the cleaner with general PNF technology to keep the oil circuit clean and clean the ternary system at the same time, so as to reduce carbon deposition, thus delaying the occurrence of engine oil burning.

When referring to Ruifeng M3, users may be concerned about its advantages and disadvantages. In fact, although this model has some minor problems, overall, its performance is quite stable. In terms of power, Ruifeng M3 switched to HFC 4G3-3D 2.0L naturally aspirated engine, and the output power was increased to 147 HP and the torque reached 196 Nm, which was 4 HP and 16 Nm higher than that of the old model, and matched with the 5-speed manual gear, although some people reported that the fuel consumption was high and the noise control needed to be improved. In addition, users may have concerns about air conditioning. However, despite these small flaws, Ruifeng M3 still shows good competitiveness in cost performance. After all, no car is perfect.

Recently, JAC launched a new IKEA version 2.0L model for Ruifeng M3 to improve the user experience. The new model not only replaced the upgraded engine, but also upgraded its configuration, including electric power steering and automatic start-stop function. The low-equipped manual luxury model is equipped with electric heating rearview mirror and rear cabin air conditioning, while the high-equipped manual luxury intelligent model adds a multi-function steering wheel, car Bluetooth and cruise control, which brings more convenience to drivers.

Although the problem of fuel consumption has been mentioned, as a small MPV, Ruifeng M3′ s overall design continues the fashion style of Ruifeng MPV family. The body lines are smooth, and the front face is designed with integrated bumper and double horizontal net, with chrome trim, showing a unique visual effect. The large triangular window design of the front door and the integrated design of the headlights and air intake grille on the front face all show the recognition of the vehicle. At the same time, the design of fog lamp and lower air inlet keeps the traditional elements, and the overall shape is simple and practical.

Generally speaking, Ruifeng M3 has performed well in cost performance and basic performance. Although there are some minor problems, the shortcomings do not cover up. For those car buyers who are looking for practicality and economy, it is a worthy choice.

Special topic: Israeli army’s large-scale air raid on Gaza Strip.

　　BEIJING, Dec. 29 (Xinhua)-Hamas leaders who control the Gaza told the Palestinian people that no matter what force Israel uses against them, Gaza will never give in to Israel. According to Iranian media reports, Hamas’s foreign propaganda officials even said that "the only way to fight back against Israeli crimes is to launch jihad and uprising".

　　After Israeli air strikes in Gaza killed 287 people, a pro-Hamas website published a letter from Hamas leader Chana to the Palestinians, which said: "We will not leave our land, we will not surrender, and we will not kneel down and give up." Chana said: "There are blood everywhere and martyrs everywhere. There may be more people injured and sacrificed, but Gaza will never surrender. "

　　In the face of Hamas’s threat, the Israeli side showed no weakness and took a tough attitude. The Israeli cabinet passed a decision on the 28th to recruit reservists. It is estimated that Israel will mobilize at least 6,500 reservists. Israeli authorities also said that they bombed more than 40 tunnels on the border between Gaza and Egypt for smuggling.

　　Israel also warned that it would launch a ground offensive against Gaza if the current air strikes failed to stop Palestinian militants from firing rockets and mortars into Israeli territory. At a cabinet meeting, Israeli Prime Minister Olmert warned his colleagues that the battle would be "long, painful and difficult".

　　Both the Hamas organization and the Israeli army have their own "weapons". The Israeli side dispatched regular troops, tanks and military aircraft to carry out large-scale military operations, while Hamas dispatched suicide bombers, guerrillas and rocket launchers. The intransigence between the two sides will inevitably lead to greater casualties, and the first victims are the people.

　　According to current statistics, since the Israeli bombing of Gaza, 287 Palestinians have been killed and nearly 1,000 injured. The major hospitals and clinics in Gaza are currently overcrowded, and the humanitarian crisis is very serious. Doctors say they can’t cope with such a large number of injured people. They said that there is a shortage of hospital beds and medicine, and more plasma is urgently needed to help the wounded.

　　Egyptian officials said on the 28th that a large number of Palestinians wanted to cross the border and enter Egypt to escape Israeli air strikes. The local refugee problem will worsen, and it will inevitably trigger the resentment of refugees. Terrorist attacks against Israel may increase greatly, and ordinary people will still be victims.

　　Although the Hamas organization and Israel’s tough attitude at this stage can win the support of some Palestinians and Israelis respectively in a short period of time, with the stagnation of the peace process, large-scale conflicts are in danger of being prolonged, and ordinary Palestinians and Israelis are still the ultimate victims.

　　Land Rover from Britain has always occupied a place in the recreational vehicle market in Europe. However, as the "Rolls-Royce in SUV", there is no doubt that Land Rover pays attention to its interior design. This time, the top models of Land Rover Range Rover will come to report with greater motivation, which is the protagonist of this article, Range Rover Supercharged.

　　

　　Regardless of whether the Land Rover Range Rover in the past was off-road oriented or the later Land Rover Range Rover was luxury oriented, after retaining two fine traditions, since it is called "Land Rover Range Rover Supercharged", this time it must be an SUV with the ultimate performance orientation.

　　The Land Rover Range Rover Supercharged is a 4.2-liter supercharged V8 engine developed by Jaguar Car Factory, which can output 390 horsepower and the maximum torque of 550Nm. Driven by the brand-new ZF six-speed automatic transmission, the Range Rover Supercharged can accelerate from 0 to 100 km/h in about 6 seconds, and the top speed is 225 km/h. Of course, the conversion function of this ZF gearbox can also let the owner experience the shifting pleasure of the handcrafted car. In addition, when encountering the terrain that must be heavily off-road, the automatic slow driving mode can also make the Range Rover Supercharged get out safely.

　

Land Rover Range Rover waded through mountains and rivers.

　　Since we talked about getting out safely, of course, we have to talk about the maneuverability of Range Rover Supercharged. The car body structure design of Range Rover Supercharged is taken from Discovery 3/LR3, another car model owned by Land Rover. Although the wheelbase has been reduced by as much as six inches, the front and rear independent double wishbone suspension with pneumatic suspension has really improved the car body shaking. In addition, through the dynamic feedback system, the car owner can really grasp the road conditions. Therefore, Range Rover Supercharged can not only conquer difficult off-road terrain, but also become a beast that devours the road. However, in order to find out the best setting, the Land Rover team also put Range Rover Supercharged on the famous Nürburgring track for testing. After completing this work, Land Rover also put Range Rover Supercharged on 20-inch shoes, which were equipped with Brembo front brakes with four-point calipers to ensure the braking performance of Range Rover Supercharged.

　

　　As for the interior part, Land Rover certainly didn’t ignore the compliment of "Rolls-Royce in SUV". In order to present the luxurious car room of Range Rover, Land Rover uses a large number of high-grade leather, wooden decorative plates and aluminum alloy as the main materials for interior decoration. The moderate support and softness of the seat bring great comfort to passengers. The button configuration on the center console is also quite neat, and the multi-function steering wheel allows the owner. In addition, the fixed-speed navigation system reduces the burden of long-distance driving, and the use of xenon headlights keeps Range Rover Supercharged in blazing with anger.

Jiyue Automobile, formerly known as Jidu Automobile, was jointly established by Baidu and Geely. In January 2021, Baidu announced that it would build a car, saying that it would formally set up a smart car company to enter the automobile industry as a vehicle manufacturer, and Geely was the strategic partner of the new company. Two months later, Jidu Automobile, initiated by Baidu and strategically invested by Geely, was officially born. With the help of Geely, the speed of Jidu automobile is extremely fast. In June 2022, Jidu ROBO-01 concept car came out.

Regarding the sales target of Jidu Automobile, Xia Yiping, CEO of Jidu Automobile, once said: "My goal is to sell 10,000 units every month. There is really no need to worry about building a car now, but it doesn’t mean that you can sell it if you build it. " In addition, Xia Yiping also revealed that "in 2028, Jiji will have the ability to deliver 800,000 car robots throughout the year". However, the reality is very skinny. Due to the lack of production qualification, Jidu Automobile cannot directly entrust Geely to produce it. In the end, Baidu and Geely officially announced the brand of "Extreme Yue Automobile" in August 2023, and the first model was named "Extreme Yue 01". At this time, Baidu had to hand over the leading power and choose to participate in the car building as a technical solution provider to ensure that the ultra-Yue car can be mass-produced smoothly, and the ultra-Yue car has officially become a sub-brand of Geely. In October 2023, Extreme Yue 01 was officially listed at a price of 249,900-339,900 yuan. In November, 2023, the official price of Chaoyue 01 was reduced by 30,000 yuan, and the price range after the price reduction was 219,900-309,900 yuan.

Although it is backed by Geely and Baidu, the sales of Extreme Yue cars are very poor. In the first half of the year, the sales volume of Extreme Yue cars was only 2,700, and the monthly sales volume was less than 500. The sales volume was so bad that it could not be described as "depressed".

Extreme Yue 07 is the first car owned by Extreme Yue Automobile and the second model owned by Extreme Yue Automobile. It was officially named in December 2023, and it was also declared in the Ministry of Industry and Information Technology, but it has not yet been listed. As a pure electric medium-sized car, the competitors of Extreme Yue 07 will aim at Tesla Model 3, Extreme Krypton 007, Extreme Krypton 007, Extreme Yue 007, Extreme Yue 07, and Lingke Z01. In the first half of the year, the best-selling pure electric medium-sized car was Tesla Model 3, with 70,500 cars, Xiaomi SU7 with 30,000 cars, and Extreme Krypton 007 with 27,200 cars. Referring to the market positioning and competing products, it is estimated that the market price of Extreme Yue 07 should be in the early 200,000 yuan.

Many friends know that the engine oil needs to be changed when the vehicle is maintained, but many people don’t know what the function of engine oil is and how to choose engine oil. Today, Xiao Jia will introduce you to the knowledge about engine oil!

Automobile lubricating oil can be generally divided into three types because of its different functions: engine oil, gearbox and differential oil, and grease (butter). The most common thing in vehicle maintenance is to change the engine oil.

Engine oil has five functions.

Lubrication function: the function of engine oil is to fill and lubricate the surfaces of moving parts and reduce the friction between moving parts. Its working principle is: the engine oil is pressurized by the oil pump and transported between the rotating parts, and an oil film is formed on the two friction surfaces to separate them, thus reducing the contact surface between moving parts, thus reducing wear and prolonging the service life of parts. There is surface friction between piston and cylinder, crank-connecting rod mechanism, cam valve train, gear rotating mechanism, etc., which must be lubricated by engine oil to ensure normal working conditions.

Cooling function: engine oil can bring back part of the heat generated between the rotating parts of the engine to the oil pan, and achieve the cooling effect through the oil pan wall. Some engines are also equipped with special engine oil radiators to achieve better cooling effect, so as to ensure the normal temperature between the rotating parts of the engine and keep the engine in normal working condition for a long time.

Sealing function: The engine oil also has a sealing function. For example, the engine piston ring and the cylinder wall are filled with engine oil, so that the contact surface and the gap have both a lubricating function and a sealing function, so that the piston can reduce air leakage when inhaling and compressing, and ensure the normal working compression ratio. If the piston ring and cylinder wall are worn, the sealing effect of engine oil can be improved by adjusting the viscosity of engine oil or adding engine oil additives, thus improving the working condition of the engine.

Cleaning function: The engine oil is pressurized by the oil pump and transported between the rotating parts of various parts for lubrication and heat dissipation. At the same time, it can also wash and clean the rotating working surface of the parts, bring the dust particles entering the engine and the garbage generated by the work to the oil pan, and keep the engine parts, rotating working surface and oil passage clean and smooth through the oil collection net and oil filter, thus ensuring the normal operation of the engine.

Rust-proof function: The working environment of the engine is complicated, and the climate change in spring, summer, autumn and winter will easily cause the metal parts to rust and deform, which will affect the normal operation of the engine and shorten its service life. The oil is pressurized by the oil pump and supplied to all parts and metal surfaces through the oil passage to form an oil film to isolate the air, which can prevent the metal surface from oxidation and rust and improve the service life of the engine.

If the engine is likened to the heart of a car, then the engine oil is the blood of the engine, which is a necessary condition to ensure the normal operation of the engine. Understanding the knowledge of engine oil, correctly selecting and using engine oil, and regularly replacing and maintaining it are very important to ensure the normal operation of the engine and prolong its service life.
