Is it good to leave a car exposed to the sun?

It is not good to leave a car exposed to the sun, as it can lead to various problems. Here are the hazards of prolonged sun exposure for cars: Engine prone to overheating: In high-temperature environments, the cooling system of a car's engine has a smaller heat dissipation temperature difference and reduced cooling capacity, making the engine prone to overheating. Battery damage: When the battery temperature is high, the electrodes may oxidize due to insulation layer aging, especially the negative electrode, which can produce white oxide deposits on the terminals, leading to unstable battery voltage. Paint aging: Car paint exposed to intense sunlight is prone to fading or reduced gloss, and may develop cracks. Interior aging: Under high-temperature exposure, the interior temperature becomes extremely high, causing the interior materials to age more quickly.

Why Are Car Bumpers Made of Plastic?

Car bumpers are made of plastic to absorb and cushion external impacts, thereby protecting the vehicle body, pedestrians, and passengers. Here are the details: Protection Principle of Plastic Bumpers: When a car collides at low speed, the plastic bumper's cushioning effect can protect the vehicle body to some extent. Additionally, due to the plastic bumper's ability to crumple, it also helps protect pedestrians in the event of a collision. Practical Significance of Plastic Bumpers: Using plastic bumpers benefits both car manufacturers and owners. For manufacturers, plastic bumpers are more cost-effective than metal ones. For owners, replacing plastic bumpers after a collision is more economical.

How Much Horsepower Does a 490 Engine Have?

The domestic universal 490 engine has a horsepower of 92 HP and a displacement of 2.7L. However, since the parameters and power tuning of 490 engines manufactured by different companies vary, the horsepower is not exactly the same. Below is a detailed introduction about horsepower: The impact of horsepower on the engine: The significance of horsepower lies in the top speed performance of the car. The greater the horsepower, the higher the engine's speed, and the stronger the acceleration. The greater the horsepower, the higher the top speed, which is the maximum speed. Conversion between horsepower and watt: 1 horsepower equals the work of completing 75 kilogram-force meters in 1 second, which is also equal to 735 watts.

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.
