What is the speed limit during the break-in period of a motor vehicle?

The speed limit during the break-in period of a motor vehicle varies depending on different stages: 1. In the initial stage of the break-in period, maintain a speed between 60 to 70 km/h, with the engine speed not exceeding 2200 rpm; 2. In the middle stage, the speed can be increased to 90 to 100 km/h, keeping the engine speed below 2500 rpm; 3. In the later stage, the speed can be raised to below 120 km/h, with the engine speed not exceeding 3000 rpm. The break-in period refers to the initial driving period after a new vehicle leaves the factory, during which the engine components are allowed to wear in smoothly. Precautions during the break-in period include: 1. Maintain smooth starts, avoid sudden acceleration, and prevent the engine from running at excessively high speeds; 2. Before starting, ensure the coolant temperature reaches at least 50 degrees Celsius, and start in a low gear.

Is it illegal to stick diamonds on the original car emblem?

Sticking diamonds on the original car emblem is not illegal: The following is an introduction to the hazards of car modifications: 1. Carbon fiber engine hood modification: This is the most dangerous modification. The original hood can deform and bend in stages during a collision, while modified parts may directly pierce the windshield, causing accidents. 2. Installing a mushroom head exhaust pipe: A mushroom head exhaust pipe can reduce intake inertia, leading to decreased low-speed torque, increased fuel consumption, and reduced low-speed power. 3. Upgrading to a large exhaust system: This reduces exhaust backpressure, resulting in decreased low-speed torque, and the engine exhaust valves may burn out easily due to extremely high temperatures. 4. Replacing with platinum spark plugs: Any new spark plug, whether it's an expensive platinum one or a cheap one costing a few dollars, will initially improve engine performance because the insulation of a new, uncontaminated spark plug is good. However, after a few days of use, it will return to its original state.

What is the ground clearance of the Geely Vision?

The minimum ground clearance of the Geely Vision under full load is 120MM. Large ground clearance: The larger the minimum ground clearance, the stronger the vehicle's ability to pass over obstacles or uneven ground, but the higher the center of gravity, reducing stability. Small ground clearance: The smaller the minimum ground clearance, the weaker the vehicle's ability to pass over obstacles or uneven ground, but the lower the center of gravity, which can increase stability. Better chassis system: Actually, there is no need to worry about the low chassis of the tenth-generation Accord. The Accord uses a front MacPherson independent suspension and a rear multi-link independent suspension. Due to the adoption of a subframe structure, the multi-link design is more flexible, with the subframe bearing most of the impact force, acting as a buffer. This structure also enhances the rigidity of the vehicle body. Therefore, the tenth-generation Accord has a relatively good chassis system and can easily pass over minor obstacles. On bumpy roads, it is advisable to reduce driving speed to minimize the risk of scraping the chassis, making rural roads manageable as well.

How Often Should a Scooter Transmission Case Be Cleaned?

Scooter transmission cases generally need to be cleaned every 2,000 kilometers. Below is relevant information about scooters: 1. Principle of scooter transmission cases: Scooters use continuously variable transmission (CVT). The principle involves the overrunning clutch driving the transmission case, which ultimately transfers power to the rear wheel for propulsion. Inside the transmission case, a driving gear rotates a driven gear via a belt. The driving gear is smaller, while the driven gear is larger. When the engine speed is too low, due to insufficient centrifugal force, the small gear drives the large gear to rotate steadily, resulting in lower vehicle speed. When the engine speed increases to a certain level, the centrifugal force causes the driving gear's belt rotation diameter to expand, effectively making the large gear drive the small gear, thereby increasing the vehicle's speed. 2. Causes of abnormal noises in scooter transmission cases: If there are abnormal noises in the scooter's transmission case, it may be due to damage to transmission gears, bearings, etc. Additionally, the gear oil should be checked for issues. Sometimes, poor brake shoes can also cause abnormal noises.

What is the appropriate engine speed for a car?

An engine speed of around 2200-2500 rpm is considered appropriate. More details about engine speed are as follows: 1. Low speed: When the engine operates below 2000 rpm while driving, it may feel underpowered. A heavy load at low engine speeds can cause damage to the engine and easily lead to carbon buildup. 2. High speed: When the engine operates above 4000 rpm, the combustion time shortens, leading to incomplete fuel combustion and a significant increase in fuel consumption. 3. Normal speed: With the engine in good condition, fuel consumption decreases, carbon buildup reduces, and damage to the engine is significantly minimized.

What are the new regulations for a 6-point deduction on a B1 driver's license?

The new regulation for a 6-point deduction on a B1 driver's license requires the holder to submit their driver's license, ID card, and health certificate to the vehicle management office within 30 days of the end of the current scoring cycle for a license review. Additionally, they must complete no less than three hours of safety education training. Below is a brief introduction to the B1 license: 1. Permitted Vehicle Types: The B1 license allows the holder to drive medium-sized passenger vehicles (including city buses with a capacity of 10 to 19 passengers), as well as vehicles permitted under C1, C2, C3, C4, and M licenses. 2. Examination Requirements: Applicants must have held a C1 license for at least three years and be between the ages of 21 and 50. To apply for an upgrade to a B1 license, the applicant must not have any full-point (12-point) records in the current scoring cycle (this year) or the most recent scoring cycle (last year). The application must be submitted to the vehicle management office in the applicant's registered residence, as regulations stipulate that the upgrade to a B1 license can only be processed at the vehicle management office in the driver's registered residence, not at a temporary residence.
