Reasons: Oxygen sensor failure; Clogged catalytic converter; Engine malfunction, etc. The following details these causes: Oxygen sensor failure: The oxygen sensor sends air-fuel ratio signals to the engine, and its failure may lead to inaccurate fuel injection, causing engine shaking. Clogged catalytic converter: The catalytic converter is a device for purifying exhaust gases. A clogged catalytic converter not only causes engine shaking but also results in a noticeable decrease in engine power. Engine malfunction: There are too many possible reasons for engine shaking. It is recommended that car owners visit a repair shop to accurately determine the fault point by reading the specific content of the fault codes through a computer, rather than making subjective guesses.

How to Check Which Model Year a Car Is?

You can check it on the nameplate located below the B-pillar on the passenger side or through the new vehicle's certificate of conformity. Here are the relevant details: 1. There is a factory-issued paper nameplate on the windshield in front of the driver's seat. The paper nameplate displays the vehicle identification number (VIN) and the official fuel consumption. If the bottom of the paper nameplate specifies the exact date (year, month, and day), then the production date on this nameplate can be used as a reference. If the nameplate only specifies the year and month, it cannot be considered as the factory release date. 2. The vehicle nameplate is a label that indicates the basic characteristics of the vehicle, including the manufacturer, model, engine power, gross weight, load capacity or passenger capacity, factory serial number, production date, and manufacturer name.

Are the Bumpers at 4S Stores Genuine?

Under normal circumstances, if you request a 4S store to install a genuine bumper, the store is usually required to use original equipment manufacturer (OEM) parts. Here are the relevant details: 1. The advantage of OEM bumpers lies in their toughness; even under high pressure, they are unlikely to deform. 2. Bumpers available in the market are generally categorized into OEM and aftermarket types. OEM bumpers are supplied directly by the original manufacturer, while aftermarket bumpers are typically produced by third-party manufacturers. 3. Since OEM bumpers are supplied directly by the manufacturer, they naturally offer better quality assurance. Although they may be more expensive, bumpers are, after all, a critical safety component.

What does cruise mean?

In automobiles, cruise refers to the cruise control system. When a car is driving steadily on the highway, the driver can use this function to maintain the current speed for constant-speed driving. After activating this function, the driver no longer needs to control the accelerator pedal, making it a highly practical feature. How cruise works: The cruise control system operates by having the cruise control module read the pulse signal from the vehicle speed sensor and compare it with the set speed, then issuing commands to the servo mechanism to mechanically adjust the throttle opening, either increasing or decreasing it, to keep the vehicle at the preset speed. Electronic multifunction cruise control eliminates the mechanical control parts of the cable-type cruise control, adopting precise electronic control for more accurate operation and avoiding the risk of mechanical failure. Components of cruise: The cruise control system consists mainly of a control switch, control module (cruise computer), and servo (actuator) in the case of cable-type cruise control. The working principle of the cable-type cruise control system involves the cruise control module reading the pulse signal from the vehicle speed sensor and comparing it with the set speed to adjust the throttle opening, either increasing or decreasing it, to maintain the vehicle at the preset speed. For example, when the vehicle is going uphill and the speed drops, the pulse signal from the speed sensor decreases, and the control module will command the servo actuator to open the throttle to a corresponding angle to maintain speed. Conversely, when going downhill, the throttle opening will be reduced.

What are the reasons for wiper blade noise?

Loud noise when the wiper is activated is mainly caused by: 1. The spring of the wiper arm being too tight. 2. Excessive wear on the friction surface of the wiper blade. 3. The friction surface of the wiper blade being uneven or deformed. 4. Solutions: (1) If the spring of the wiper arm is too tight, the solution is to slightly stretch the spring. (2) If the wiper blade is worn or the friction surface is uneven or deformed, it is recommended to replace the wiper blade. (3) You can check if the frame holding the rubber strip of the wiper is slightly bent.

Does the car radiator need cleaning?

Car radiators do need cleaning. Here are the relevant steps: 1. Ensure the engine is cool and turned off. 2. Open the drain plug at the bottom of the radiator to let the coolant flow into a bucket. The coolant should be properly disposed of to avoid environmental harm. 3. Close the drain plug and fill the radiator with water. 4. Start the engine, turn on the heater control system (this will open the heater control valve), add cooling system cleaner, and let the engine idle for 30 minutes (or follow the instructions on the cleaner bottle). 5. Turn off the engine and let it cool for 5 minutes. Drain the liquid from the radiator. 6. Close the drain plug, fill the radiator with water, and let the engine idle for 5 minutes. Then refill with a 50/50 mixture of water and ethylene glycol antifreeze/coolant (use the same type of coolant previously used in the car).

How to Check the Manufacturing Date of a Tire?

On one side of the tire, there is usually a DOT marking. The tire manufacturing date code format is as follows: the first two digits indicate the production week, and the last two digits indicate the production year. Below is related information about the functions of tires: 1. Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 2. Transmit traction and braking torque to ensure good adhesion between the wheel and the road surface, improving the car's power, braking, and passability; work together with the car suspension to mitigate impacts during driving and dampen resulting vibrations. 3. Prevent severe vibrations and early damage to car components, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure driving safety, handling stability, comfort, and energy efficiency.
