Why is the speed limit on Wushen Expressway set at 80km/h?

The primary reason for the 80km/h speed limit on Wushen Expressway is that the Hunan section passes through many mountainous areas with complex road conditions and numerous tunnels. Below is relevant information about expressway speed limits: Speed limits in special sections: Areas such as tunnel entrances, inside tunnels, accident-prone sections, large bridges, roads under maintenance, temporary speed limit zones, and long downhill sections all have speed limit signs. Drivers must pay attention to roadside speed limit indicators and drive cautiously. Penalties for speeding: Speeding within 10% of the limit results in a warning. Speeding between 10%-20% incurs a 3-point deduction; speeding between 20%-50% incurs a 6-point deduction; and speeding over 50% incurs a 12-point deduction, along with varying fines for each offense.

What kind of engine oil makes the Yamaha JOG i quieter?

Yamaha JOG i tends to be quieter when using non-counterfeit oil, oil with appropriate viscosity, oil with stable performance across temperature variations, and high-grade branded engine oil. Below are relevant details: Introduction to Yamaha JOG i: The Yamaha JOG i is equipped with a 'Blue Core' engine. While it emphasizes fuel efficiency, its power output is impressive for a 125cc displacement scooter. It offers quick acceleration and strong low-end torque, outperforming even the DL250 in this aspect. However, the front suspension of the JOG i is notably subpar. Function of Engine Oil: Engine oil, also known as engine lubricant (English name: Engine oil), has a density of approximately 0.91×103 (kg/m3). It serves multiple functions including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. Often referred to as the 'blood' of an automobile, engine oil consists of base oil and additives. The base oil forms the primary component of lubricants, determining their fundamental properties, while additives compensate for and enhance the base oil's performance shortcomings, imparting new characteristics, making them a vital part of lubricants.

Does an SUV Belong to the Category of Small Sedans?

An SUV does not belong to the category of small sedans; rather, it is classified as a small general passenger vehicle. The original intention of an SUV (Sports Utility Vehicle) is to be a versatile vehicle with ample luggage space comparable to that of a sedan, while also offering superior off-road capability compared to sedans. Below are the reasons: Definition Criteria: For passenger vehicles, the vehicle type is often determined by the number of seats and its intended use. SUVs typically accommodate 5-7 passengers and can be categorized by length into compact SUVs and large SUVs. Compact SUVs generally have a length of 4.4-4.65 meters, while large SUVs are usually around 4.7-5 meters. Classification Rules: Passenger vehicles with a length of less than 6 meters and seating capacity of 9 or fewer are classified as small general passenger vehicles. If the vehicle length exceeds 6 meters and the seating capacity is more than 9 but fewer than 20, it is classified as a medium-sized passenger vehicle.

What are the items in the driving test physical examination?

Driving test physical examination includes vision, color discrimination, hearing, and physical integrity. Here are the detailed requirements: Vision requirements: For monocular vision impairment, the naked or corrected visual acuity of the right eye must be above 5.0 on the logarithmic visual acuity chart, with a horizontal field of vision reaching 150 degrees. Hearing requirements: Must be able to distinguish the direction of sound sources with both ears at a distance of 50 centimeters from a tuning fork. Limb requirements: Both thumbs must be intact, and each hand must have at least three other fingers intact with normal movement function; both lower limbs must be intact with normal movement function, and the length difference between the lower limbs must not exceed 5 centimeters. For automatic transmission vehicles, the right limb must be intact; there must be no movement dysfunction in the limbs.

Is Front-Wheel Drive or Rear-Wheel Drive Better for Sedans?

Both front-wheel drive and rear-wheel drive have their own advantages and disadvantages for sedans, depending on the vehicle model and usage environment. Below are the pros and cons of front-wheel drive and rear-wheel drive: Pros and Cons of Front-Wheel Drive: The advantage is that the front-wheel drive system has a simpler structure, making manufacturing and maintenance costs relatively lower. The disadvantage is that its climbing ability is inferior to rear-wheel drive, and it may experience understeer in handling. Pros and Cons of Rear-Wheel Drive: The advantages include better handling and stability, as well as stronger climbing ability. The disadvantages are that the driveshaft can affect interior space, fuel consumption, and transmission efficiency, and it may also lead to oversteer.

Can a Car Be Driven When Overheated?

When a car is overheated, it should not be driven. The vehicle should be turned off promptly to prevent further damage, such as hose bursts or engine failure. Below are the reasons for engine overheating and the function of the car's coolant temperature sensor: Reasons for engine overheating: A lack of coolant inside the engine, caused by leaks in the cooling system, can lead to a rise in engine temperature. If the thermostat becomes stuck and fails to open the large coolant circulation loop in time, it can also trigger a high-temperature warning. Function of the car's coolant temperature sensor: It measures the temperature of the engine coolant. The electronic control unit detects the engine coolant temperature based on this change—the lower the temperature, the higher the resistance, and vice versa. The electronic control unit uses this data to measure the engine coolant temperature and adjusts fuel injection and ignition timing accordingly.
