What are the symptoms of a broken timing belt in a car?

Why is the car dashboard key light flashing?

The flashing key icon on the dashboard indicates that the anti-theft system is activated. When this indicator light is on, the car cannot be started. Multiple failed attempts to start the engine will lock it, which is also known as engine immobilization. The anti-theft indicator light has two states: armed and disarmed, and it flashes at different frequencies for each state. The indicator light will flash regularly, and the flashing frequency also varies when unlocking and driving. Components of the car dashboard: 1. Speedometer and odometer: Consists of two gauges, one for speed and the other for mileage. 2. Tachometer: The tachometer is usually located within the instrument panel. 3. Indicator and warning lights: Timing belt indicator, exhaust temperature warning light, brake warning light, ABS warning light, etc. 4. Oil pressure gauge: The sensor for the oil pressure gauge is a piezoresistive sensor, which is fixed to the engine oil line with threads. 5. Water temperature gauge: The sensor for the water temperature gauge is a thermistor sensor, which is fixed to the engine cooling water passage with threads. 6. Fuel gauge: The fuel gauge contains two coils, located on the "F" and "E" sides respectively.

Why doesn't the car move when pressing the accelerator?

The reasons why a car cannot move when pressing the accelerator should be determined based on specific conditions, as follows: If the accelerator is pressed, the tachometer shows an increase in engine speed, but the car cannot continue moving, it indicates a clutch failure. The clutch needs to be inspected to determine whether its working condition is normal. If the accelerator is pressed, the tachometer shows no change in speed, and the car does not move, it means the car is not injecting fuel. This could be due to issues with the fuel supply system or the accelerator cable. The fuel supply system and accelerator cable should be checked promptly, and the fuel supply system may also need appropriate cleaning. If black smoke appears when pressing the accelerator, but the car does not move, it indicates a fault in the ignition system. The car's ignition should be checked to see if it is functioning properly. The power source of a car is mainly provided by the combination of the intake system, fuel supply system, related electronic circuits, and electronic components. Therefore, when the car cannot move despite pressing the accelerator, these parts should be inspected in detail to see if they are affecting the car's movement.

What type of vehicle is a light-duty flatbed truck?

According to the regulations on permissible driving license categories, light-duty flatbed trucks fall under the category of small vehicles and can be driven with C1, C2, C3, or C4 driver's licenses. A light-duty truck is defined as a cargo vehicle with a length less than 6000mm and a total mass less than 4500kg, excluding mini cargo vehicles, three-wheeled vehicles, and low-speed trucks. Additional information: 1. Light-duty cargo vehicles are a type of truck. According to China's motor vehicle specifications, 'light-duty' is defined as having a total mass of 6000kg or less. Additionally, trucks are categorized into four types based on load capacity: heavy-duty, medium-duty, light-duty, and mini. 2. With changes in the market demand structure and product adjustments for cargo vehicles, competition in the cargo vehicle market has evolved from 'medium trucks' to a diverse competitive landscape encompassing heavy-duty trucks, medium-duty trucks, light-duty trucks, and mini trucks. As a result, competition in China's cargo vehicle market has shifted from being broad to more segmented, with each segment showcasing distinct competitive dynamics.

How to Buy a Used Car Without a Temporary Residence Permit?

Methods for buying a used car without a temporary residence permit are as follows: 1. Obtain the vehicle transfer application form and agreement from the vehicle management office. 2.

Vehicle insurance: confirm that the chassis number and engine number on the insurance policy match those on the vehicle license and check if the policy is still valid. 3. Vehicle registration certificate: inspect if the font on the registration certificate matches that on the vehicle license, and verify if the chassis number and engine number are the same as those on the license. Check if the manufacturing date and registration date (if the gap exceeds six months for a domestic car, it might be a stock vehicle) match the dealer's description, and review the transfer records to see if there have been frequent transfers in a short period.

What is the difference between the internal circulation and external circulation in a car?

Internal circulation refers to the air inside the car being heated or cooled and then recirculated back into the car, while external circulation refers to drawing air from outside the car, heating or cooling it, and then bringing it into the car, which means exchanging air between the inside and outside of the car. Internal circulation allows the air inside the car to circulate when the car is closed, and the icon typically shows a closed car interior with a circulating arrow. External circulation, on the other hand, brings outside air into the car, and the icon usually shows an open car with an air arrow pointing into the car from the outside. Whether it's heating or cooling, it's best to first turn on internal circulation. Although the temperature inside the car will drop, the carbon dioxide exhaled by passengers will increase. Therefore, it's advisable to switch to external circulation every hour to refresh the air. When turning on the air conditioning for cooling or heating, you can start with internal circulation to quickly lower or raise the temperature inside the car. Once the temperature stabilizes, it's good to switch to external circulation to exchange air with the outside. However, if the outside air quality is poor, such as in heavy traffic with lots of exhaust fumes or in a poorly ventilated underground garage, avoid using external circulation. If you're driving on the highway, do not open the windows—simply turn on external circulation.

Where to Find the Complete Engine Number?

The engine number is generally located on the outer surface of the engine cylinder block, or on the vehicle's nameplate or the nameplate inside the engine compartment. You can also find the engine number on the car purchase invoice, the factory certificate of compliance, the operating permit for commercial vehicles, the vehicle purchase tax payment certificate, the registration records at the public security authority, the vehicle insurance card, or the simplest and most direct method is to check the vehicle registration book or the vehicle's driving license. The engine number is like a person's ID number, representing each vehicle. It contains very important information about the vehicle. The engine model is an identification code assigned by the engine manufacturer according to relevant regulations, corporate or industry practices, and the attributes of the engine. It represents information such as the manufacturer, specifications, performance, features, technology, purpose, and batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose passenger vehicles are required to indicate the professional manufacturer, model, and production number of the engine. It is important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's range, and engine models can be the same. The engine number refers to the production number of the engine, with each engine having a unique number that cannot be duplicated. Composition of the vehicle engine number: First part: Includes the product series code, generation symbol, and local or corporate code, which are selected by the manufacturer as needed and must be approved and filed by the industry standardization unit. Middle part: Consists of the cylinder number symbol, cylinder arrangement symbol, stroke symbol, and cylinder diameter symbol. Rear part: Composed of structural feature symbols and usage feature symbols. Tail part: Distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same product series, the manufacturer selects appropriate symbols, and the rear and tail parts can be separated by a hyphen.
