Do I need to warm up the car if it's not driven in winter?

It is necessary to warm up the car in winter if it's not driven. Warming up the car for 1 to 2 minutes is appropriate, allowing the engine coolant to reach normal temperature before driving. Here are the reasons for warming up the car in winter: 1. After prolonged parking, the engine oil flows back to the oil pan at the bottom of the engine. 2. Before the engine reaches its operating temperature, the fuel supply system cannot effectively vaporize gasoline completely due to low temperature. 3. In cold conditions, gear oil flows to the lower part of the transmission. Here are the effects of not warming up the car in winter: 1. It causes wear and tear on the engine, transmission, and various parts of the engine, leading to a shortened lifespan. 2. It increases fuel consumption and makes the engine more prone to carbon buildup.

What is the normal range for tire pressure?

Tire pressure between 2.3 to 2.5 bar is considered the normal range, with the maximum not exceeding 3.0 bar and the minimum not falling below 2.1 bar. According to relevant data, the standard air pressure for ordinary car tires should preferably be: 2.5 bar for front wheels and 2.7 bar for rear wheels in winter; 2.3 bar for front wheels and bar for rear wheels in summer. This ensures both safe driving and comfort, while also minimizing fuel consumption. Tire pressure refers to the air pressure inside the tire, which is essentially the blood pressure of a car. The level of tire pressure plays a crucial role in the performance and power of the vehicle.

What does OBD mean on a diesel vehicle?

OBD on a diesel vehicle refers to the On-Board Diagnostics system. This system continuously monitors the engine's operation to check whether the vehicle's emissions exceed the standard limits. If they do, it will immediately issue a warning. If the On-Board Diagnostics system is not functioning or functioning abnormally, the vehicle will not pass the annual inspection. It is essential for the owner to promptly address any vehicle faults to avoid affecting normal vehicle usage. OBD can monitor the working conditions of the engine's electronic control system and other functional modules of the vehicle in real-time during operation. If any abnormal conditions are detected, it identifies specific faults based on specific algorithms and stores them in the system's memory as diagnostic trouble codes. The useful information obtained from the system's self-diagnosis can assist in vehicle maintenance and repairs. Technicians can use the vehicle manufacturer's specialized equipment to read the fault codes, enabling quick fault localization for efficient vehicle repairs and reducing the time required for manual diagnosis.

What does 'engine' mean in a car?

Engine in a car refers to the motor, commonly known as the engine. Many modern vehicles are equipped with an automatic start-stop system for the engine. The system determines whether to shut down the idling engine based on the vehicle's usage and automatically restarts it when needed. The engine is the core component of a motor, hence it's often used interchangeably with the term 'motor'. The main part of the engine is the cylinder, which serves as the power source of the entire vehicle. The cylinder includes the cylinder block, intake port, fuel injection port, exhaust port, piston, and spark plug (for gasoline engines). The cylinder injects gasoline and air through the intake and fuel injection ports, thoroughly mixing them inside. When the spark plug ignites the mixture, it combusts violently, pushing the piston downward to generate power. Simultaneously, the immense pressure from the combustion pushes open the one-way valve's exhaust port to expel the waste gases.
