What is engine knocking?

Engine knocking refers to the metallic knocking sound that occurs when the pressure rise rate in the automobile cylinder is too high. The following are relevant explanations: 1. Causes of knocking: When the piston is near the top dead center during the compression stroke, the piston's tilt and the change in side force direction cause the contact surface between the piston and cylinder to shift from the secondary thrust side to the main thrust side, resulting in lateral oscillation. This causes the engine to periodically produce the knocking sound of the piston striking the cylinder. 2. Types of knocking: Knocking is divided into combustion knocking and mechanical knocking. The sharp metallic knocking sound near the top dead center caused by combustion reasons is called combustion knocking or hot knocking. If operation continues under this condition, the engine's maximum combustion pressure will abnormally increase, thermal stress on components will rise, mechanical load will also increase, and under impact forces, moving parts will wear excessively and lead to damage. The dull heavy knocking or friction sound caused by abnormal clearance between moving parts and bearings, occurring at or near the top and bottom dead centers or when passing through the middle, is called mechanical knocking or cold knocking. 3. Solutions for knocking: Remove the cylinder head, extract the piston, and replace the cylinder liner, piston, piston rings, and connecting rod.

Is the SVS warning light in a car serious?

This indicates a severe vehicle condition. When the SVS warning light appears on the dashboard, it signifies an engine malfunction. The driver should immediately stop the vehicle safely and contact professional maintenance personnel for repairs. Below are relevant explanations: 1. Definition of the car dashboard: The car dashboard is a warning device that primarily reflects the working status of various vehicle systems. 2. Most common warning lights: Battery indicator, fuel indicator, hazard warning light, washer fluid indicator, front/rear fog light indicators, and electronic throttle indicator. 3. Dashboard components: Common dashboard displays typically include the speedometer (showing vehicle speed), oil pressure gauge, fuel gauge, coolant temperature gauge, tachometer, and charging indicator.

How many times can a temporary license plate be applied for in Beijing, and how long is each application valid?

There is no limit on the number of times a temporary license plate can be applied for in Beijing, but only one temporary license plate can be issued at a time. However, the temporary license plate for a new car can be extended, with a maximum of three extensions totaling 21 days. Below are the methods for displaying temporary license plates on a car: One plate: A single temporary license plate should be affixed to the lower left or right corner of the front windshield, ideally without obstructing the driver's view. Two plates: If there are two temporary license plates, one should be affixed to the front windshield, and the other should be placed on the lower left corner of the rear windshield inside the car. If there is no space on the rear windshield, the second temporary license plate should be carried in the vehicle.

What does the T/C warning light indicate?

TC refers to the Traction Control warning light. TC stands for the Traction Control System, also known as the Track Control System. Its function is to improve vehicle passability. When the ABS anti-lock braking system detects wheel slippage, the traction control system applies braking to the slipping wheels to prevent traction loss. Below are relevant details: 1. Working principle of the Traction Control System: The system replaces the mechanical connection between the accelerator pedal and throttle with an electronic throttle control device. The ECU receives throttle pedal data from sensors, generates control voltage signals accordingly, and the servo motor adjusts the throttle based on these signals to reduce throttle opening and control wheel slippage. 2. How to resolve when the TC light illuminates: Normally, the vehicle's traction control system remains active. If the TC light comes on, it may indicate accidental deactivation via the traction control switch near the gearshift. Reactivating this switch will turn off the TC light. If not caused by accidental operation, the system may require professional repair at a 4S shop. 3. Common causes of Traction Control System malfunctions: Oil pressure leakage due to wear in actuator gears or impellers triggering warnings; Throttle body contamination causing 20% opening that leads to ECU misdiagnosing TC faults; Dirty engine oil clogging solenoid valve filters; Solenoid valve failure.
