Does a Car Need Water?

A car needs water, but it is better to add antifreeze. Antifreeze has a high boiling point: The boiling point of antifreeze is above 120 degrees Celsius, while water boils at only 100 degrees Celsius. Using antifreeze can prevent your car from "boiling over" in the summer. Water easily forms scale: Using water instead of antifreeze can easily lead to scale formation, requiring frequent replacement, whereas using antifreeze eliminates this concern. Antifreeze prevents corrosion: Water can cause some corrosion to the cooling system, while antifreeze contains additives that prevent corrosion and rust. Therefore, to better protect your family car, never use tap water as a substitute for antifreeze.

What are the penalties for reversing immediately after entering the highway entrance?

Reversing immediately after entering the highway entrance should result in a fine and 12 demerit points imposed by the traffic police department. Road Traffic Safety Law: Driving a motor vehicle in reverse, against the flow of traffic, or making a U-turn across the central divider on a highway will result in 12 demerit points per violation. The highway entrance is specifically designed for entering the highway; once you enter the entrance ramp, reversing is prohibited. Reversing violates traffic regulations and will be penalized. Highway Precautions: Driving medium-sized or larger passenger or cargo vehicles, school buses, or hazardous material transport vehicles at speeds exceeding 20% above the limit on highways or urban expressways, or exceeding 50% above the limit on other roads, as well as driving other motor vehicles at speeds exceeding 50% above the limit, will all result in demerit points.

What Causes a Sudden Increase in Engine Noise?

Reasons for a sudden increase in car engine noise include excessive carbon buildup in the engine, aging engine mounts, and abnormal operation of engine cylinders. Excessive Carbon Buildup: The cause is too much carbon buildup inside the engine or the use of substandard fuel. Therefore, it is necessary to clean the carbon deposits promptly and switch to the correct fuel grade. Aging Engine Mounts: Engine mounts are rubber blocks between the engine and the frame, designed to reduce vibrations generated during engine operation and provide cushioning. Over time, engine mounts may age or loosen, leading to increased engine noise. When engine mounts show signs of aging or loosening, they should be replaced promptly. Abnormal Operation of Engine Cylinders: If one or more cylinders in the engine are not functioning properly, it can also result in increased engine noise. Abnormal operation of engine cylinders is often manifested by severe shaking of the exhaust pipe, requiring immediate inspection and repair.

Will a 72V Charger Damage a 48V Battery?

No. The DC voltage of a 72V charger is much higher than the withstand voltage of a 48V battery, meaning the 48V battery cannot handle the voltage from the 72V charger and may be damaged or even destroyed. Abnormal battery overheating: Due to the excessive voltage, prolonged high-current charging will occur, leading to abnormal battery overheating and even thermal runaway, which can cause the battery to swell or result in more severe accidents. Swelling: For lead-acid batteries, one standard voltage unit is 2V. If the standard voltage exceeds 3V or even 4V, the lead-acid battery may swell or even explode.

Can A1 and A2 be held simultaneously?

A1 and A2 driving licenses can be held simultaneously, but upgrading to A1A2 requires additional licensing. The vehicle types permitted by an A1 license include large buses that can carry more than 20 passengers, as well as vehicles with a body length exceeding 6 meters, which must also be driven with an A1 license. Other vehicle types permitted by an A1 license are: A3 (city buses), B1 (medium-sized passenger vehicles), B2 (large trucks), C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed cargo vehicles), C4 (three-wheeled cars), M (wheeled self-propelled machinery). However, only an A2 license permits driving tractor vehicles. The vehicle types permitted by an A2 license are: Heavy and medium-sized full trailers, semi-trailer combinations, B1, B2, C1, C2, C3, C4, M.

What are the three conditions for running a red light?

Determined by capturing three photos with electronic cameras: a photo of the vehicle crossing the intersection stop line, including the traffic light showing red and the license plate number; a photo of the vehicle completely passing the stop line, including the traffic light showing red and the license plate number; a photo of the vehicle continuing to move, comparing to see if the vehicle's position has changed, including the traffic light showing red and the license plate number. Capturing these three photos can determine that the vehicle has run a red light. The act of running a red light is clearly defined in the "Road Traffic Safety Law." Article 26 states that traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to pass, and a yellow light serves as a warning. A red light is a traffic signal prohibiting passage, and if a vehicle passes through an intersection when the light is red, it constitutes the traffic violation of running a red light. Six situations involving running a red light: Stopping immediately after crossing the line at a red light (when the light turns red, the vehicle cannot stop in time, and the front of the vehicle crosses the stop line): If the vehicle has just crossed the stop line when the light is red but stops immediately, this act of running a red light will not be penalized. However, if there is obvious movement after crossing the line, it will be penalized. The three photos captured by the electronic eye for running a red light are: the front wheels crossing the stop line, the rear wheels crossing the stop line, and the front wheels crossing the opposite stop line. Only when all three photos are present will it be considered running a red light, resulting in a 6-point deduction under the new regulations. Running a red light under the direction of a traffic officer (the signal light is red, but the on-duty traffic officer signals to proceed): When there is a conflict between the signal light and the traffic officer's gesture, motor vehicle drivers must obey the on-site command of the traffic officer. If running a red light occurs due to the traffic officer's on-site command, the driver can obtain a diversion certificate from the local traffic police station to avoid penalties. If the party disagrees with the penalty, they can appeal through administrative reconsideration or administrative litigation. Stopping after the entire vehicle has crossed the stop line at a red light (failing to brake in time, causing the entire vehicle to cross the stop line): If the entire vehicle crosses the stop line and does not continue to move, this is not considered running a red light. However, this situation constitutes crossing the stop line and stopping, which, according to Article 4, Item 5 of the new "Points for Road Traffic Safety Violations," results in a 1-point deduction for not driving or stopping as required at an intersection. Reversing after crossing the stop line (attempting to avoid penalties by reversing after crossing the stop line at a red light): Motor vehicles are not allowed to reverse at railway crossings, intersections, one-way roads, bridges, sharp turns, steep slopes, or tunnels. If reversing is done in violation, a warning or fine may be imposed. Accidentally running a red light behind a large vehicle (due to the large vehicle blocking the view and following it through the intersection): Drivers must maintain sufficient visibility to see the traffic signals ahead and ensure a safe braking distance. Generally, if a motor vehicle is photographed following a large vehicle, it is because they rushed through the intersection when the signal changed. This behavior will be penalized as running a red light. Passing through an intersection during a yellow light (passing through the intersection when the signal turns yellow): The traffic police department states that according to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," vehicles that have already crossed the stop line when the yellow light is flashing may continue to pass. If the yellow light has already turned red and the vehicle continues to rush through, it will be considered running a red light if photographed.
