Why do the high beams turn on when using the turn signal?

It could be due to a short circuit in the wiring or an issue with the combination switch. Turn signal structure and principle: Resistive types can be further divided into thermal wire type (electrothermal) and flap type (spring-loaded). Electronic types can be categorized into hybrid (relay with contacts and electronic components) and fully electronic (no relay). For example, the spring-loaded flasher utilizes the principle of current thermal effect, using thermal expansion and contraction as the driving force to cause sudden movement of the spring plate, thereby connecting and disconnecting the contacts to achieve light flashing. Hazards of high beams: The probability of traffic accidents at night is 1.5 times higher than during the day, with 60% of major traffic fatalities occurring at night. 30-40% of nighttime accidents are caused by the misuse of high beams. When human eyes are exposed to the strong light of car headlights, the pupils automatically contract from the normal 5~8 mm to 1 mm or even smaller, reducing the amount of light entering to less than 1/30 of the original. After passing another vehicle, since the pupils cannot recover in time, the amount of light entering suddenly decreases, resulting in a phenomenon similar to night blindness, leading to numerous traffic accidents.

Is it necessary to start the engine when using a circulation machine to replace coolant?

When using a circulation machine to replace coolant, you should not start the engine. Functions of coolant: Coolant is a special additive-containing liquid primarily used in liquid-cooled engine cooling systems. It provides excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. Composition of coolant: The main components of coolant are: 50% purified water, 40% methanol, and 10% other substances. Types of coolant: Coolant is generally classified into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. Coolant should not be mixed: It is necessary to use the same brand of coolant. Different brands may have varying production formulas, and mixing them could lead to chemical reactions between additives, rendering them ineffective. How to choose coolant: The basic indicators for coolant are freezing point and boiling point. Available freezing points on the market include -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region.

Can You Honk the Horn in Urban Areas?

Local policies vary, and honking is prohibited in some urban areas. Honking regulations: Honking in areas or sections where it is prohibited may result in fines as stipulated by law. Relevant laws and regulations clearly state that vehicles such as fire trucks, ambulances, and engineering rescue vehicles can use horns and sirens with compliant audio when performing emergency tasks. How car horns work: An electric car horn produces sound through the vibration of a metal diaphragm. The electric car horn consists of an iron core, a magnetic coil, contacts, an armature, a diaphragm, etc. Current flows through the contacts to the coil, which generates a magnetic force that pulls down the armature, forcing the diaphragm to move. The movement of the armature causes the contacts to open, interrupting the current and causing the coil's magnetic force to disappear. The diaphragm, under its own elasticity and the action of the spring plate, returns to its original position along with the armature, closing the contacts and reconnecting the circuit. Current flows through the contacts to the coil again, generating magnetic force and repeating the above process. This cycle repeats continuously, causing the diaphragm to vibrate and produce sound.

What are the reasons for loud car noise?

Car engine noise can be caused by the following reasons: 1. Oil issue: If the vehicle's engine oil viscosity is too high, it can easily lead to operational problems in the engine, reducing lubrication effectiveness and resulting in loud engine noise. Therefore, it is necessary to promptly visit a repair shop to check if the oil needs to be replaced. 2. Loose belt: Check if the belt is loose. Sometimes, a loose belt can cause the noise in the engine compartment to increase. 3. High water temperature: If the engine noise is loud, it could also be due to high water temperature. Check if the temperature gauge is normal and if there is any smoke in the engine compartment. It is essential to ensure the coolant is replaced before winter. 4. Idle speed: If the noise feels particularly loud during idle and the vehicle's idle speed is high, it is likely that the throttle body, intake duct, and fuel injectors need cleaning. 5. Poor sound insulation: If the engine sounds normal from the outside but the noise feels loud inside the car, it indicates poor vehicle sound insulation. Check the vehicle's sealing strips for any signs of aging. Alternatively, improve the vehicle's sealing effect and test the noise level again.

What does the dripping teapot symbol on the car mean?

The dripping teapot symbol on the car is used to indicate whether the oil pressure is normal. If the oil pressure is abnormal, it will light up. At this time, it is necessary to check whether the engine has any faults, and if necessary, you can go to the 4S store for maintenance. The reasons for the constant illumination of the oil pressure warning light are: 1. Insufficient engine oil storage: This causes the lubrication system to have no oil or insufficient oil, resulting in low oil pressure. Solution: Add oil to the engine. 2. The oil is too dirty or viscous: This prevents the oil pump from effectively sucking and pumping oil, resulting in low or no oil pressure. Solution: Replace the engine oil. 3. The oil becomes thin or the engine temperature is too high, causing the oil to thin: This leads to oil leakage from the engine's friction gaps, resulting in low oil pressure. Solution: Change the oil or repair the cooling system. 4. Oil pipe leakage: The oil pump is damaged or its components are excessively worn, leading to reduced or no oil suction and pumping, resulting in low or no oil pressure. Solution: Repair the engine.

Is driving at 65 km/h on a national road with a speed limit of 60 km/h considered speeding?

Driving at 65 km/h in a 60 km/h speed limit zone exceeds the speed limit by less than 10%, which results in a warning without penalty points. On a road with a 60 km/h speed limit, the speed should not exceed 66 km/h. Penalties for speeding: On roads with speed limits between 50 km/h and 80 km/h, exceeding the speed limit by less than 10% results in a warning. Exceeding the speed limit by 10% to less than 20% incurs a corresponding fine. Exceeding by 20% to less than 50% incurs a corresponding fine. Exceeding by 50% to less than 70% incurs a corresponding fine. Exceeding by 70% or more incurs a corresponding fine. Hazards of speeding: When speeding, vehicles are often in a state of accelerating to follow or overtake other vehicles. Due to the close following distance, the driver's view is obstructed, leading to unclear observation and inaccurate judgment of the road ahead, increasing the risk of accidents. Additionally, speeding significantly reduces the driver's vision, with higher speeds causing more severe vision impairment, making accidents more likely.
