Can the Car Be Locked If the Engine Is Still Running?

When the vehicle's engine is still running, the doors cannot be locked. Below is relevant information about the engine shutting off: 1. Common reasons for a car to automatically shut off: (1) Vacuum leakage in the intake pipe; (2) Unstable idle speed caused by improper idle adjustment, dirty throttle body, or poor idle control system performance; (3) Unstable fuel pressure, such as excessive wear or poor contact of the electric fuel pump brush, or clogged fuel pump filter; (4) Blocked or leaking EGR valve. 2. Measures to prevent forgetting to turn off the engine when exiting the vehicle: (1) Check the tachometer and display screen. Before exiting, see if the display screen has turned off and gone black. Also, check if the tachometer reads zero. (2) Turn on the daytime running lights. In the light settings, enable the daytime running lights. This method is quite effective. After locking the doors, check if the daytime running lights are off, indicating that the engine is definitely shut off.

What does in-store license plate registration mean?

In-store license plate registration means that the 4S dealership handles the license plate registration and vehicle inspection for the car owner. The owner doesn't need to manage it themselves, as the registration procedures are quite complicated. Nowadays, 4S dealerships basically provide one-stop services. Additional information: 1. Vehicle license plate: A vehicle license plate is a standardized hard plate with registration codes issued by vehicle management authorities after reviewing, inspecting, and registering vehicles that have applied for plates according to national vehicle management regulations. Vehicle license plates are the abbreviated term for both the plate itself and the vehicle registration certificate. 2. Vehicle registration certificate: The vehicle registration certificate is issued by vehicle management authorities, recording the main contents of the vehicle's initial registration. It is kept by the owner and carried with the vehicle as a standardized registration booklet for recording changes and inspections at any time. According to the 'Road Traffic Management Regulations,' both the vehicle license plate and registration certificate are legal documents permitting a vehicle to drive on public roads.

What Does Engine Displacement Mean?

Engine displacement refers to the volume of fluid that is inhaled or expelled per stroke or cycle. Below is an introduction to engine displacement: 1. The relationship between engine compatibility and displacement: In automobiles, how well the engine is matched with the vehicle has a significant impact on fuel economy. If a small-displacement engine is poorly matched, it may not be more fuel-efficient than a large-displacement engine and could even consume more fuel. 2. Classification of car levels: In China, car levels are classified based on engine displacement. Mini cars have a displacement of ≤1.0L; compact cars have a displacement ranging from 1.0L to 1.6L; midsize cars have a displacement ranging from 1.6L to 2.5L; executive cars have a displacement ranging from 2.5L to 4.0L; and luxury cars have a displacement of >4.0L.

What does 10w-40 mean for engine oil?

10w-40 for engine oil refers to: 10 represents the minimum operating temperature of the oil at -25 degrees Celsius; W stands for all-season use (Winter or Summer); 40 represents the high-temperature viscosity of the oil—the higher this number, the thicker the oil is at high temperatures. About engine oil: Engine oil, also known as motor lubricant, serves functions such as lubrication and friction reduction, auxiliary cooling, sealing against leaks, rust and corrosion prevention, and shock absorption for the engine. SAE viscosity grades for winter oils are: 0W, 5W, 10W, 15W, 20W, 25W. The symbol W stands for Winter, and the smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. SAE viscosity grades for summer oils are: 20, 30, 40, 50. The larger the number, the higher the viscosity, and the higher the applicable maximum temperature.

What is the relationship between engine speed and torque?

Power P = Torque × Angular velocity ω. The formula shows that under fixed power conditions, torque is inversely proportional to engine speed. The faster the speed, the smaller the torque, and vice versa. Below is relevant information: 1. Speed: In an engine, speed refers to the number of revolutions the crankshaft makes per unit of time and is directly related to vehicle speed. When the gear remains unchanged, an increase in engine speed leads to a corresponding increase in vehicle speed. The speed is reduced and the torque is increased through the entire transmission system, including the gearbox and final drive, and is ultimately reflected in the wheels. Therefore, the ratio of engine speed to wheel speed is the transmission ratio of the entire drivetrain. 2. Torque: Torque is the force that causes an object to rotate. Engine torque refers to the moment output from the crankshaft end. Under fixed power conditions, it is inversely proportional to engine speed—the faster the speed, the smaller the torque, and vice versa. It reflects the vehicle's load capacity within a certain range.

What are the three guarantees for tire quality?

Tire quality three guarantees refer to the policy of refund, replacement, and repair for sold products. The three guarantees for tires include: 1. Basic policy: If quality issues are found before actual use after purchase, users can exchange for new tires. For appearance quality issues, both parties can negotiate a solution. If quality issues are discovered during use, the compensation standard is calculated based on the wear depth of the tread pattern. 2. Compensation standard: For genuine tires within three years from the production date, compensation is provided according to different manufacturers' policies. For passenger car tires (semi-steel), compensation is usually available when tread wear is above 3.5MM with no wear fee. For bias-ply and truck/bus tires (full-steel), compensation requires the tread pattern to be more than half of the new tire's depth, with certain wear fees charged according to manufacturers' policies.
