Over the years of using my car, I have encountered the issue of a hissing sound during acceleration multiple times. The most common causes are a loose alternator belt or AC belt, aged rubber, or problems with the tensioner, which creates noise from friction against the pulleys during acceleration. Another frequent reason is an exhaust system leak, such as a gap in the manifold joint, causing a hissing sound as gases escape. Once, I ignored it, only for the belt to snap and cause an alternator failure, leaving me stranded on the road. Additionally, for turbocharged models, worn turbo blades or poor pipe sealing can also lead to such noises. Under acceleration, when the engine load increases, the sound becomes more noticeable—prompt inspection is crucial to avoid impacts on driving safety and fuel consumption. Don’t delay; have a mechanic check it out to resolve minor issues before they escalate.

Does passing during a yellow light count as running a red light?

According to Article 38 of 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 at an intersection may continue to pass. If the yellow light is already on and you continue to force your way through, being caught on camera in such a situation will also count as running a red light. According to the relevant provisions in Article 10 of the 'Regulations on the Handling of Road Traffic Safety Violations,' motor vehicle drivers who violate traffic signal lights at intersections will be penalized with 6 points. Additionally, according to the relevant provisions in Article 90 of the 'Road Traffic Safety Law,' a fine may also be imposed. Criteria for determining running a red light: Electronic cameras will take three photos as evidence for running a red light: 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 available will it be considered running a red light. According to Article 11 of the 'Regulations on the Handling of Road Traffic Safety Violations,' if you run through the stop line when the red light is on but manage to stop the vehicle even if you have already crossed the line, it will not be considered running a red light. However, it will be considered stopping beyond the line, and according to traffic laws, it is classified as driving or stopping at an intersection not in accordance with regulations, resulting in a 2-point penalty. How to avoid running a red light while driving: When there are arrow signal lights, follow the arrow lights; otherwise, follow the circular lights; When the red light is on, the front of the vehicle must not cross the stop line; When the yellow light is on, the front of the vehicle must not cross the stop line; When the green light just starts flashing, if you are close and moving fast, you should pass because you might not be able to stop in time and cross the stop line; if you are far away, moving slowly, or the intersection is congested, you should stop; When driving in the city, develop the habit of looking for traffic lights whenever you see a crosswalk or stop line at an intersection.

What are the main components of a car's power system?

The automotive power system mainly consists of a battery, alternator, and voltage regulator. The alternator is responsible for charging the battery to maintain it in a fully charged state over time, while both the battery and alternator supply power to all electrical components in the vehicle. Below are detailed explanations: 1. The battery is an essential part of a car, which can be categorized into traditional lead-acid batteries and maintenance-free batteries. Since lead-calcium alloy is used for the grid frame in these batteries, water decomposition during charging is minimal, resulting in low water evaporation. 2. The alternator serves as the primary power source of the vehicle. Its function is to supply power to all electrical devices (except the starter) when the engine is running normally (above idle speed), while simultaneously charging the battery. 3. The voltage regulator is necessary because the alternator is driven by the car's engine, whose speed is not constant. This leads to unstable output voltage from the alternator, hence requiring an electronic device to control the alternator.

Which One is the Fog Light on a Car?

Fog lights are generally located below the car's headlights, and the fog light button is on the left side of the steering wheel, above the headlight switch on the body panel. Here are the details: 1. Car fog lights can increase the running distance and improve the visibility of the driver and surrounding traffic participants, allowing oncoming vehicles and pedestrians to spot each other from a farther distance. 2. Fog lights are divided into front fog lights and rear fog lights. Front fog lights are usually bright yellow, while rear fog lights are red. 3. The symbol for the rear fog light is slightly different from that of the front fog light. The front fog light symbol has downward light lines, while the rear fog light symbol has parallel lines, generally located on the dashboard inside the car.

What is the Difference Between 2.0L and 2.5L Car Engines?

The differences between 2.0L and 2.5L car engines are as follows: 1. Power Output: A 2.0L engine has a smaller displacement compared to a 2.5L engine. A larger displacement means the engine can release more energy per unit time, resulting in better performance. Therefore, a 2.0L engine delivers less power than a 2.5L engine. 2. Fuel Consumption: Due to its smaller displacement, a 2.0L engine consumes less fuel than a 2.5L engine when traveling the same distance. Additional details are as follows: 1. Turbocharging technology was not initially developed for car engines; it was first used in aircraft engines. Turbocharging helps address the issue of insufficient air intake in aircraft engines at high altitudes. 2. Later, turbocharging technology was widely adopted in both gasoline and diesel car engines. Turbocharging allows for increased air intake without increasing the engine's displacement.

Will a Car Get Damaged by Sun Exposure?

It is rare for a car to be damaged by sun exposure. Here are the effects of prolonged exposure to sunlight: Vehicle Aging: Extended exposure to sunlight can accelerate the aging of plastic components in the vehicle. Examples include the dashboard with numerous wiring, car doors, and the sealing rings around the sunroof. Particularly, sealing rings are prone to aging and cracking after prolonged sun exposure, significantly reducing their sealing performance, which may lead to water leakage or seepage. Significant Safety Hazards: Flammable items should not be left inside the car, especially lighters. Lighters exposed to prolonged sunlight inside the car may explode, posing serious safety risks.

How Long Can a Vehicle Go Without Inspection?

A vehicle can go without inspection for up to three months. If the inspection is overdue for less than three months, you can simply make up for it and will receive a verbal warning without a fine. If the inspection is overdue for more than three months but less than two years, you will need to pay a fine and receive a 3-point penalty. If the vehicle has not been inspected for more than two years, its registration file will be canceled. A vehicle is considered overdue for inspection once it exceeds the validity period of the inspection. Vehicle inspections can be conducted up to three months in advance. If a vehicle is driven on the road without undergoing the required periodic safety inspection, a 3-point penalty will be imposed, along with a warning or fine. According to Article 49 of the "Regulations on the Registration of Motor Vehicles": The owner of a motor vehicle may apply for an inspection compliance mark at the vehicle management office of the registration location up to three months before the expiration of the inspection validity period. According to Article 90 of the "Road Traffic Safety Law of the People's Republic of China": If a motor vehicle driver violates the road traffic safety laws or regulations regarding road traffic rules, they shall be given a warning or fined. If other provisions of this law apply, penalties shall be imposed accordingly. According to Article 16 of the "Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China": Motor vehicles shall undergo safety inspections at the following intervals from the date of registration: Passenger vehicles for commercial use must be inspected once a year within the first 5 years; after 5 years, once every 6 months; trucks and large or medium-sized non-commercial passenger vehicles must be inspected once a year within the first 10 years; after 10 years, once every 6 months; small and mini non-commercial passenger vehicles must be inspected once every 2 years within the first 6 years; after 6 years, once a year; after 15 years, once every 6 months; motorcycles must be inspected once every 2 years within the first 4 years; after 4 years, once a year; tractors and other motor vehicles must be inspected once a year. If a commercial motor vehicle passes the safety inspection within the specified inspection period, it does not need to undergo another safety inspection.
