Changan Automobile's development history is as follows: 1. Origins: The history of Changan Automobile can be traced back to the Westernization Movement during the late Qing Dynasty. In November 1862, Li Hongzhang authorized British national Halliday Macartney and Chinese official Liu Zuoyu to establish the Shanghai Arsenal in a temple outside Songjiang, Shanghai. 2. Renaming: In 1957, the central government proposed the production policy of "combining military and civilian production, mastering dual capabilities." Guided by this policy, over 200 workers from Factory 456, despite facing insufficient funds and lacking machine tools and molds, spent three months repeatedly measuring and replicating each component based on the Willys M38A1. They eventually trial-produced China's first off-road vehicle - the Yangtze River Brand Model 46 off-road vehicle. Simultaneously, the state-owned Factory 456 under the Central Ordnance Bureau was renamed Changan Machinery Manufacturing Plant. 3. Transformation: In 2017, Changan Automobile launched the "Third Entrepreneurship - Innovation and Entrepreneurship Plan," aiming to build efficiency and software capabilities as core competencies and transform into an intelligent, low-carbon mobility technology company.

What is the range of the BYD Song Pure Electric?

The range of the BYD Song is 405 kilometers. As a new energy vehicle, range is one of the key metrics for electric vehicles. The longer the range, the more practical the electric vehicle becomes. Several major factors affect the range of an electric vehicle: Battery Capacity: The most direct factor affecting the range of an electric vehicle is undoubtedly the battery capacity. Larger battery capacity allows for longer range. However, as the battery capacity of new energy vehicles increases, the battery weight also increases, which can lead to reduced range due to the added load. This trade-off makes energy density an important factor in evaluating battery quality. Drag Coefficient: The drag coefficient refers to the amount of air resistance a vehicle must overcome while driving, which directly affects power output during movement. Previous studies have shown that at a speed of 60 km/h, 60% of a car's power is used to overcome air resistance. Therefore, a lower drag coefficient results in less resistance and relatively lower energy consumption. Vehicle Weight and Load: Heavier new energy vehicles place greater loads on bearings and tires, leading to increased rolling resistance. This requires more energy during acceleration, thereby affecting range. Research has shown that reducing the weight of a new energy vehicle by 100 kg can increase the range by 10-11%, while also reducing battery costs by 20% and daily wear costs by 20%.

What is the real fuel consumption of the Nissan Patrol 4.0?

4.0 Patrol real fuel consumption is generally around 22 liters per 100 kilometers, with careful driving at least 20L, and on highways around 15L. Maintenance costs: For a car in this price range, the overall maintenance costs are not high. Patrol advantages: It is not comfortable to drive in the city, nor is it advantageous on highways, as it is positioned as a hardcore off-road vehicle. Its strength lies in its ability to handle tough situations, such as traversing mountains and rough terrains, where it truly shines. Therefore, if you mainly drive in the city and are concerned about fuel consumption, the Patrol is not the best choice, as it clearly cannot compete with sedans in the same price range. However, if you enjoy off-roading, the Patrol is definitely worth considering compared to other models in the same price range.

What kind of engine oil is best for the Chery Arrizo 5?

Arrizo 5 requires SM-grade or higher specification engine oil. Manufacturer's recommendation: The original factory uses SM-grade 10W-40 engine oil, with semi-synthetic oil being the preferred choice. If budget allows, full synthetic oil is even better. Additional notes: You can select the appropriate engine oil based on your current driving environment. There are no strict brand requirements as long as the oil meets the specifications. If you live in a colder climate, consider switching to 5W-40 grade oil or using full synthetic oil. Full synthetic oil offers better performance, resulting in lower engine noise and reduced wear, though it requires more frequent oil changes.

What kind of engine oil is best for Honda Lingpai?

Honda Lingpai is suitable for using fully synthetic engine oil. Fully synthetic engine oil has better quality, smoother cold starts, better fuel efficiency, and longer oil change intervals. Fully synthetic engine oil has low evaporation loss: Synthetic oil is generally a pure compound with a narrow boiling point range, and its evaporation loss is much lower than that of mineral oil, which can reduce fuel consumption, decrease exhaust emissions, and extend the service life of catalytic converters. In addition, compared with traditional mineral oil-type engine oil, synthetic engine oil also has excellent chemical stability, good radiation resistance, high oil film strength, and low foaming characteristics. Therefore, high-end cars generally choose synthetic engine oil. Fully synthetic engine oil has strong high-temperature oxidation resistance: The thermal oxidation stability of synthetic oil is much better than that of mineral oil-type engine oil, meaning it has a lower tendency to produce acidic substances and sludge due to oxidation. Under various harsh operating conditions, it can provide appropriate lubrication and effective protection for the engine, thus having a longer service life and ensuring the stability of the oil's performance over long-term use. In the same working environment, synthetic oil has a much longer service life than mineral oil, so although the cost is higher, when compared to the number of oil changes, it is not much higher than mineral oil.

What does 225/55r18/98h mean?

225/55r18/98h has the following meanings: 1. 225: The nominal section width of the tire is 225mm. The tire section width refers to the maximum distance between the outer sides of the tire when inflated to the specified pressure. 2. 55: The nominal aspect ratio of the tire. The aspect ratio refers to the percentage of the tire's sidewall height relative to its width. A smaller value indicates a flatter tire shape. 3. R18: The type is a radial tire, with a rim diameter of 18 inches. 4. 98h: 98 is the load index, and H is the speed symbol. 98 indicates that the maximum load capacity is 750kg, and H indicates that the maximum speed limit is 210km/h.
