What is the history of automobile development?

History of automobile development: 1. Germans invented the automobile: (1) In 1867, German engineer Otto developed the world's first reciprocating piston-type four-stroke engine. (2) In 1885, German Karl Benz purchased Otto's patent and installed an internal combustion engine along with an accelerator on a three-wheeled carriage. On January 29, 1886, he applied for the patent for the first three-cylinder automobile, with patent certificate number 37435, obtaining the invention rights for the world's first automobile. This day is widely regarded as the birth date of the modern automobile. Note: Benz Patent-Motorwagen. (3) In 1886, German Gottlieb Daimler produced the world's first four-wheeled automobile, considered the ancestor of four-wheeled vehicles, equipped with a 1.1 horsepower gasoline engine. (4) In 1887, the automobile pioneer Benz & Cie. was founded, and in 1890, Daimler-Motoren-Gesellschaft was established.

Must China VI vehicles only use Sinopec or PetroChina fuel?

There is no such requirement. Any standard gasoline available on the market is acceptable. Fuel requirements for China VI vehicles: 1. Regarding gasoline: China VI vehicles do not require special gasoline; they only need to use the octane rating specified in the vehicle's manual. However, it is advisable to avoid refueling at small gas stations to prevent using lower-quality fuel. 2. Regarding engine oil: When selecting engine oil for China VI vehicles, low-ash oil should be the first choice. This type of oil contains minimal ash content, significantly reducing the risk of particulate filter clogging. Check the oil can packaging for certifications—if present, it can be safely used (always use the oil grade specified in the manual). It is recommended to avoid small gas stations for refueling China VI vehicles, mainly for the following reasons: 1. Unreliable fuel quality: Small gas stations often lack advanced storage and filtration technologies compared to major brands, leading to gasoline with more impurities. These impurities can clog the fuel injection system, causing significant damage to the vehicle. 2. Unknown fuel sources: Small gas stations typically source their fuel from local small-scale refineries, and some may even mix fuel from these refineries with branded gasoline, making it difficult to distinguish genuine from counterfeit. This makes it hard to ensure consistent fuel quality.

What is the maximum wading depth of the Sagitar?

According to official information, the maximum wading depth of the Sagitar is 30 cm. Common tire specifications include 205/55R17 and 225/45R18, with a body length of 4753 mm, a vehicle weight ranging from 1355 to 1410 kg, and a body structure of a 4-door, 5-seater sedan. The maximum wading depth refers to the deepest water level a car can safely pass through. Generally, the maximum wading depth for sedans does not exceed 30 cm, while SUVs have a higher wading depth, though it is still advisable not to exceed 50 cm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30 cm, the Audi A4 has 32 cm, the Infiniti QX50 has 80 cm, the Land Rover Range Rover has 90 cm, the Jeep Compass has 48 cm, and the Highlander has 45 cm. SUVs clearly outperform sedans in terms of maximum wading depth. Generally, when driving through water, vehicle owners should take different measures depending on the water depth and the car's specifications, as detailed below: If the water reaches the height of the exhaust pipe, it is relatively safe. Even if water enters the exhaust pipe, the pressure inside is sufficient to expel it. As long as the engine is not turned off in the water, water will not flow back into the vehicle. If the water reaches the height of the door frame, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly located at the bottom, which could lead to short circuits, damaging critical electrical components and preventing the car from starting. If the water reaches the height of the air intake pipe, it is extremely dangerous. Driving directly into such conditions could cause the engine to stall immediately, leading to permanent damage or rendering the engine unusable.
