What Causes the Car Engine Light to Illuminate?

What symptoms are likely to occur when the engine thermostat is faulty?

When the engine thermostat is faulty, the following symptoms are likely to occur: 1. The thermostat fails to open, the temperature gauge displays in the high-temperature zone, the radiator fan does not operate, and the engine temperature rises; 2. The thermostat does not close, the water temperature rises slowly, and during winter, the water temperature remains in the low-temperature zone even after 10 to 20 minutes, with high idle speed. The reasons for a faulty engine thermostat include: 1. Extended warm-up time, operation of the vehicle at low water temperature, leading to the formation of acidic substances from combustion gases and condensed water on the cylinder walls, corroding the cylinders; 2. Liquid fuel and water wash away the lubricating oil film on the cylinder walls and flow down to the oil pan, diluting the lubricating system's oil, resulting in wear of cylinder liners and piston components; 3. Defects in the cylinder block repaired with adhesive, excessive temperature fluctuations causing frequent contraction and expansion of the cylinder block, leading to adhesive failure and diesel engine malfunctions.

Is a six-year-old car subject to biennial inspection thereafter?

Yes. Private cars that have been in use for 6 years will be subject to biennial inspections. Vehicles that have already passed the annual inspection need to undergo the inspection before the expiration date. The new regulations include 7 to 9-seater non-operational mini and micro passenger vehicles (excluding vans) within the 6-year exemption range. For non-operational mini and micro passenger vehicles (excluding vans) that have been in use for more than 6 years but less than 10 years, the inspection frequency is adjusted from once a year to once every two years. Below is relevant information about vehicle inspection: 1. Article 49 of the "Motor Vehicle Registration Regulations" states that the owner of a motor vehicle may apply for an inspection compliance mark at the vehicle management office of the registration location within three months before the expiration of the motor vehicle inspection validity period. 2. Before applying, the owner must resolve all traffic violations and accidents related to the vehicle. When applying, the owner must fill out an application form and submit the vehicle license, compulsory traffic accident liability insurance certificate, vehicle and vessel tax payment or exemption certificate, and motor vehicle safety technical inspection compliance certificate.

Do Americans drive on the left or right side?

In the United States, the driver's seat is on the left side, and the passenger seat is on the right, similar to China, where traffic follows right-hand driving rules. Except for Hong Kong, all other regions in China have the driver's seat on the left. Hong Kong, as a special administrative region under the 'One Country, Two Systems' policy, still adheres to left-hand driving as per historical regulations. Below is relevant information about automobiles: 1. Automobile Driving: Globally, it is divided into two categories. One is island nations, known as the 'Island Group' (e.g., the UK, Japan), where the driver's seat is on the right. The other is continental nations, referred to as the 'Continental Group' (e.g., China, the USA), where the driver's seat is on the left. 2. Driver's Seat Position: Mercedes-Benz, the world's earliest automobile company, initially designed the driver's seat in the center, with the steering wheel and gear shift both positioned in the middle of the car. However, based on ergonomics, people are accustomed to using their right hand, and gear shifting and braking rely on pushing the lever, so the driver's seat was set on the right side.

Can an electric car purchased over a year ago still be registered?

An electric car purchased over a year ago can still be registered. The following points should be noted for vehicle registration: 1. Vehicle photography: The photographer will set up the number plate based on the last four digits of the chassis number, place it in the lower right corner of the windshield, and then take photos of the car. Before taking photos, the "CCC" sticker and the "Automobile Fuel Consumption Label" sticker on the windshield must be removed. It is best to complete this task before arriving at the vehicle management office, as these two stickers are difficult to peel off. 2. Rubbing materials: Rubbing is usually done in the inspection area of the vehicle management office. It is important to ensure that the number of rubbings is complete. For registration, two copies of the engine number and three copies of the chassis number rubbings are required. 3. Inspection line: All self-branded vehicles are exempt from inspection, while non-exempt vehicles need to undergo an "inspection line" test, including tests for power, lights, exhaust, and brakes. Professionally speaking, the vehicle inspection line is called the Motor Vehicle Safety Technology Inspection, which serves as the main technical basis for the traffic management department of public security authorities in conducting safety technology inspections for new vehicle registration, periodic inspections of in-use vehicles, and accident vehicle inspections, commonly known as the major inspection.
