Here are some lesser-known facts about cars: Using the heater barely affects fuel consumption: Many experienced drivers claim that using the air conditioning increases fuel consumption, so in winter when you can stay warm by layering up, they suggest wearing more clothes and avoiding the heater to save fuel. However, in reality, the heating system in fuel-powered cars utilizes waste heat from the engine's cooling system, meaning using the heater hardly impacts fuel consumption. Turning up the AC temperature in summer doesn't save fuel: For the vast majority of mid-to-low-end cars on the market, since they typically use fixed-displacement air conditioning compressors, once the AC is turned on in cooling mode, the energy consumption is fixed. Adjusting the temperature only changes the ratio of hot to cold air through the vents, so turning up the AC temperature slightly in summer won't save fuel.

As a car enthusiast, I love uncovering little-known facts, like how airbags were originally invented to protect astronauts before being adapted for vehicles. Or why car tires are black - it's due to the addition of carbon black for enhanced durability, otherwise they'd be white or gray. Another cool tidbit: the three-point seatbelt was conceived by a Volvo engineer in 1959 who generously made the patent free, saving countless lives. Did you know windshield wipers were patented by a woman in 1903? These details make driving safer and more interesting - paying attention to maintenance tips can genuinely prevent accidents. Here's a fuel-saving tip: idling over 30 seconds actually consumes more fuel than restarting the engine, something many drivers don't realize. Try manually turning off the engine to save money. Ultimately, these bite-sized knowledge nuggets are simple to learn but highly practical.

Can I drive on the yellow dashed bus lane?

Bus lanes generally have time restrictions, prohibiting non-bus vehicles during peak hours, while allowing other vehicles to use them outside peak periods. Regulations may vary by region, so pay attention to signage at intersections. Here's relevant information: Bus lanes are dedicated lanes for buses, similar to small vehicle lanes, large vehicle lanes, and motorcycle lanes on urban arterial roads, typically found in major cities. The numbers marked on bus lanes indicate exclusive operating hours when other vehicles are prohibited. Establishing bus lanes reflects public interest, culture, and awareness, serving as a fundamental measure to ensure urban road efficiency during peak hours while promoting green and low-carbon travel concepts among the public.

Will U-turns on Highways Definitely Be Captured by Cameras?

Making a U-turn on a highway will be captured by surveillance cameras. Here are the relevant details: Penalties for highway U-turns: According to the "Road Traffic Safety Law," reversing, driving in the opposite direction, or making a U-turn on a highway not only incurs a fine of 200 yuan but also results in a full 12-point deduction from the driver's license. Precautions for highway driving are as follows: Pre-drive vehicle inspection: Before driving, the driver should conduct a comprehensive check of the vehicle. Adjusting mirrors: Note that the adjustment methods for the left and right side mirrors slightly differ. Seat adjustment: A proper seating position can help alleviate driver fatigue during long-distance highway driving.

Why doesn't the barrier gate automatically lower after being raised?

If the barrier gate doesn't automatically lower after being raised, it may be due to aging. Here are some precautions for using a car engine: Avoid driving in neutral gear: The engine itself has a fuel-cut function during deceleration, and driving in neutral is actually less fuel-efficient. Pay attention to observation when using the vehicle: If you notice oil stains on the ground, determine whether there's an engine oil leak and promptly communicate with the car 4S store to eliminate potential safety hazards. Don't turn off the engine immediately: For cars equipped with turbochargers, avoid turning off the engine immediately after high-speed driving or climbing slopes. Let it idle for 10 minutes before shutting down. Cars with turbochargers accumulate carbon deposits several times faster than naturally aspirated cars.

Does Remote Starting the Vehicle's Air Conditioner Harm the Car?

Remote starting the vehicle's air conditioner does not harm the car. Here are some details about the car air conditioning system: Lack of refrigerant or leaks: Most cases of insufficient cooling are due to a lack of refrigerant. You can first check the air conditioning pressure. If both high and low pressures are low, it generally indicates a refrigerant shortage. Simply add refrigerant until the pressure is appropriate. Excessive system pressure: The car air conditioning system has inherent pressure due to the compressor's operation. Overfilling refrigerant or blockages in the pipes can cause the system pressure to rise too high. In such cases, the control system will disengage the compressor's electromagnetic clutch to stop the compressor. The solution is simple: after confirming the pressure exceeds the standard, release some refrigerant to restore normal pressure.

What Happens When a Stationary Car Gets Flooded?

A stationary car that gets flooded will be rendered inoperable. Below is an introduction to some aspects of auto insurance: Components: Auto insurance typically consists of basic coverage and additional coverage. Basic coverage is further divided into vehicle damage insurance and third-party liability insurance. Coverage Details: Vehicle damage insurance compensates for losses to your own vehicle; third-party liability insurance covers damages to entities outside your own vehicle, such as people and public property you hit, or the other party's vehicle; passenger liability insurance compensates for injuries or property losses to people inside your own vehicle; theft insurance covers losses when your vehicle is stolen; no-deductible coverage ensures 100% compensation in case of an accident. Without no-deductible coverage, you are responsible for 30% of the deductible in each accident.

What Causes Poor Acceleration in CVT?

Due to unstable oil pressure regulation, the valve body is damaged, resulting in poor acceleration. Here is the relevant introduction: CVT Introduction: CVT refers to a type of automotive transmission, also known as a continuously variable transmission. The difference between CVT and geared transmissions is that its gear ratio is not a series of discrete points but a continuous range of values, thereby achieving good fuel economy, power performance, and smooth driving, while also reducing emissions and costs. Working Principle: In a CVT transmission system, traditional gears are replaced by a pair of pulleys and a steel belt. Each pulley is actually a V-shaped structure composed of two conical discs. The engine shaft is connected to the small pulley, which drives the large pulley through the steel belt.
