Is it necessary to use 95 octane gasoline for the 2021 CR-V?

According to the official vehicle manual recommendation, the 2021 CR-V should use 92 octane gasoline, so there is no need to use 95 octane gasoline. For the 2021 CR-V, in addition to checking the suitable gasoline grade in the vehicle manual, you can also check the fuel tank cap, which will also indicate the recommended gasoline grade. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the use of some new technologies nowadays, the gasoline grade cannot be solely determined by the compression ratio. A high compression ratio can also be adjusted to use lower octane gasoline. This is because, apart from the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane number, the higher the octane value and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the 2021 CR-V occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane value will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. This is because the significantly lower octane value reduces the gasoline's ignition point, causing it to ignite prematurely during the compression stroke. If the fuel ignites before the spark plug fires, resistance will occur during the upward stroke. This resistance makes the engine run very unstably. If the knocking is mild, it may only increase noise without obvious damage to the engine. However, if the knocking is severe, it indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

What are the body dimensions of the Ford S-MAX?

The length, width, and height dimensions of the Ford S-MAX are 4760mm/1910mm/1640mm, which are official data. The length of the Ford S-MAX refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and respectively touching the outermost protruding parts at the front and rear of the vehicle. The width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and respectively touching the outermost rigid fixed protruding parts on both sides of the vehicle. The height refers to the distance between the highest point of the vehicle and the supporting plane of the vehicle. The naturally aspirated engine of the Ford S-MAX has a maximum power of 117.6 kW and a maximum torque of 205 N·m. The maximum power speed of this engine is 6800 rpm, and the maximum torque speed is 4000 rpm. It is equipped with multi-point fuel injection technology and uses an aluminum alloy cylinder head. This engine is paired with a 6-speed automatic manual transmission. The country has relevant regulations regarding the dimensions of vehicles. According to the national standard "GB1589-89," the total width of a vehicle does not include the rearview mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that, according to national standards, the significance of vehicle width data lies in ensuring enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5 meters to meet the usage requirements of public roads.

What kind of vehicle has a green license plate starting with 'A'?

A green license plate starting with 'A' indicates that the vehicle is a pure electric vehicle. Green license plates are designated for new energy vehicles, and the license plate number can distinguish between pure electric vehicles and plug-in hybrid vehicles. If the first character is the letter 'D', it signifies a pure electric vehicle. Additionally, plates starting with 'A', 'B', 'C', or 'E' also denote pure electric vehicles. If the first character is 'F', it represents a plug-in hybrid vehicle or a fuel cell vehicle. Plates starting with 'G', 'H', 'J', or 'K' also indicate plug-in hybrid or fuel cell vehicles. The background color for small new energy vehicle license plates is gradient green, while large new energy vehicle license plates have a yellow and green background. For small vehicle license plates, 'D' or 'F' is the first character in the serial number, whereas for large vehicle license plates, 'D' or 'F' is the last character in the serial number. As the government continues to promote environmental protection, the number of registered pure electric new energy small vehicles has rapidly increased. The original license plate numbering rules could no longer meet market demand, leading to the official introduction of 'A'-starting license plates for pure electric new energy small vehicles. New energy vehicle license plates measure 480*140mm, with the length increased by 40mm compared to standard license plates. For large new energy vehicles, the rear license plate width is reduced by 80mm. New energy vehicle license plates feature a green background. Small new energy vehicle plates transition from white to green from top to bottom, while large new energy vehicle plates have a yellow regional code at the front and a green six-digit area at the back, with the number of digits increased from five to six. New energy vehicle license plates are produced using pollution-free hot stamping methods, ensuring environmentally friendly manufacturing. They also incorporate anti-counterfeiting technologies such as QR codes, anti-counterfeiting watermarks, and laser patterns. Pure electric vehicles (BEV) are entirely powered by rechargeable batteries (such as lead-acid, nickel-cadmium, nickel-metal hydride, or lithium-ion batteries). These vehicles use an onboard power source to drive the wheels via an electric motor, meeting all road traffic and safety regulations. They have a relatively smaller environmental impact compared to traditional vehicles. According to the State Council's 'Energy-saving and New Energy Vehicle Industry Development Plan (2012-2020)', new energy vehicles mainly include pure electric vehicles, plug-in hybrid vehicles, and fuel cell vehicles. Pure electric vehicles have shorter ranges, while fuel cell vehicles are less common. Plug-in hybrid vehicles are the most prevalent new energy models among domestic manufacturers. The most notable difference is in charging: plug-in hybrid vehicles have larger batteries that can be externally charged, allowing them to operate in pure electric mode. Once the battery is depleted, they switch to hybrid mode (primarily using an internal combustion engine) and recharge the battery as needed.
