Highway driving at night requires the use of high beams. The reasons and precautions for using high beams are as follows: Reasons for using high beams on the highway: Because street lights on highways are generally not very dense, it is often difficult to clearly see the road conditions. Moreover, the illumination range of low beams is only 30 meters. Vehicles on the highway move very fast, and if there is an obstacle ahead, the driver would not have enough time to react at such a short distance, which can easily lead to accidents. Precautions for using lights on the highway: If the distance to the vehicle ahead is less than 100 meters, it is best to switch from high beams to low beams. There are many tunnels on the highway, and there is no need to keep high beams on when passing through them, as the lighting inside tunnels is very bright.

When driving on the highway at night, I always prefer using low beams because they provide moderate illumination without dazzling drivers in the opposite or same direction. On highways, speeds are high, and visibility extends far. Using high beams directly on others can cause temporary blindness and even lead to rear-end collisions. Having driven on highways many times myself, I only switch to high beams on open, vehicle-free stretches to see the road ahead clearly, but immediately switch back to low beams as soon as I spot any lights or vehicle shadows. Extra caution is needed in rain or fog—using high beams can actually impair your own vision. I make it a habit to check my lights beforehand to ensure they’re working properly. Safety comes first, especially during nighttime driving when fatigue is common. Proper use of lights can prevent 90% of accidents.

Is motorcycle electricity AC or DC?

Motorcycles rely on DC (direct current) from the battery, while the electricity generated by the magneto is AC (alternating current). Detailed introduction: In the past, motorcycle lighting systems mostly used AC, which would brighten as the throttle increased, being extremely unstable and prone to burning out bulbs. Modern motorcycle lighting systems mostly use DC, directly supplied by the battery, providing stable illumination that does not vary with throttle position. Motorcycle charging: Remove the battery from the motorcycle and charge it with a dedicated charger. Since motorcycle battery charging requires a charger, its function is to convert 220V electricity to 12V. The motorcycle's magneto generates AC, which is then converted to DC and stabilized by the rectifier before charging the battery.

What is the speed of a Formula car?

F1 Formula cars have a top speed of 350 km/h: F1 cars: The top speed of an F1 car can reach 350 km, but due to track conditions, fuel load, and tires, F1 cars are not the fastest cars on Earth; F1 cars are not tools for creating top speeds but are sports equipment. Therefore, from the beginning, F1 cars do not pursue the highest speed but the highest RPM. Currently disclosed figures show that Ferrari and BMW engines have exceeded 18,000 RPM. Factors affecting speed: For an F1 car to achieve its top speed, it also depends on track conditions. In the world, only three tracks—Nürburgring in Germany, Monza in Italy, and Spa in Belgium—can allow the highest speeds. These tracks are also known as the world's three fastest circuits.

Is it mandatory to wear a full-face helmet for motorcycles?

Motorcycles do not necessarily require wearing a full-face helmet. Helmet: A helmet consists of a shell, cushioning layer, padding, wearing device, and accessories. The shell is made of tough material capable of absorbing certain impact energy, directly protecting against external forces impacting the skull. The cushioning layer absorbs more impact energy than the shell, providing sufficient buffering against mechanical shocks. Function of wearing a helmet: In the event of a traffic accident, wearing a helmet means the tough outer shell can first directly resist external forces impacting the head, mitigating the instantaneous collision force. The inner cushioning layer further reduces the intensity and speed of the external forces acting on the skull while dispersing the force, thereby preventing damage to the brain.

What is the reason for the seat belt not fastening?

Seat belt not fastening is due to damage to the seat belt buckle. Seat Belt: Seat belts have become a primary consideration for drivers and passengers, and one of the most important features in cars. Traditional components ensuring safe driving, such as rearview mirrors and side mirrors (traditional rearview systems), seat belts, AIRBAG (airbags), and ABS (anti-lock braking systems), are well-known to drivers and passengers and are commonly used in imported luxury vehicles. Function of Seat Belts: In the event of an emergency stop, seat belts can restrain the driver and passengers in their seats to prevent forward movement, thereby protecting them from secondary collisions and injuries.

Can the Engine Still Run if the Connecting Rod is Broken?

Engine connecting rod broken cannot run. Main causes of engine connecting rod fracture: Water entering the engine cylinder (combustion chamber); continuous fuel injection by the engine; poor lubrication between the connecting rod and crankshaft leading to seizure; quality issues with the connecting rod itself; incorrect maintenance procedures or improper operation; damage to the crankcase system causing oil to flood the cylinder, among other reasons. Water entering the cylinder: When a vehicle is driven on roads with standing water, the engine may suck water into the cylinder. The water initially entering the cylinder quickly turns into vapor under the high temperature of the cylinder block, preventing the formation of a combustible mixture in that cylinder. As more water enters, it accumulates on top of the piston, reducing the effective volume of the combustion chamber and increasing compression resistance, thereby increasing the pressure transmitted from the piston to the connecting rod. When the amount of water reaches a certain level, the compression stroke essentially becomes the compression of water, causing the pressure on the connecting rod to increase sharply, leading to bending, deformation, and even fracture, potentially breaking the engine block.

What Causes Engine Resonance for Over Ten Minutes When Cold?

Cold start vibration is mainly caused by carbon deposits, weak ignition, low cylinder pressure, substandard fuel, etc. Detailed causes: Excessive carbon deposits on throttle body, fuel injectors, and intake passages; When there's excessive carbon buildup inside the engine, gasoline sprayed by the cold start injectors gets largely absorbed by the deposits, resulting in an overly lean air-fuel mixture during cold starts that causes vibration; Mechanical failures in ignition coils, spark plugs, or fuel injectors leading to cylinder misfires; Insufficient fuel pressure or cylinder pressure causing power deficiency; Poor fuel quality; Damaged or excessively dirty idle control valve; Intake manifold leaks; Damaged engine mounts or cushion pads; Oxidized or low-grade engine oil with poor low-temperature fluidity, leading to inadequate cold start protection. Recommendation: It's advisable to visit a 4S shop or repair facility for inspection and maintenance to enhance the vehicle's safety performance.
