SVS light on indicates that the engine control unit has detected an error signal from a certain sensor or that it has exceeded the usage standard. When the ignition switch is turned on, the car's SVS indicator light will illuminate for an automatic check and then turn off after a few seconds, which is a normal phenomenon. If it stays on, it indicates a fault in the car's electronic control system. Reasons for the SVS light to stay on: 1. Poor engine combustion state, excessive wear; 2. Engine knocking; 3. Poor quality of car fuel; 4. The inside of the engine cylinder is not clean, with accumulated carbon deposits; 5. The electronic control unit cannot obtain engine data.

What does the P gear in a car mean?

Car P gear is the parking gear. This gear is used when parking. When you step on the brake to stop the vehicle, engage this P gear, which will lock the wheels and prevent the car from moving. Automatic transmission generally refers to the car's automatic gear-shifting mechanism. While driving, the control system of the automatic transmission automatically selects the appropriate gear based on the engine speed and load, replacing the driver's subjective judgment of timing and gear-shifting operations. The automatic transmission uses planetary gear mechanisms for shifting, which can automatically change gears according to the degree of the accelerator pedal and changes in vehicle speed, while the driver only needs to control the speed by operating the accelerator pedal.

How Often Should Motorcycle Clutch Plates Be Replaced?

Motorcycle clutch plates should be replaced every 2 years or 40,000 kilometers. Clutch plates are composite materials primarily designed for friction functionality while also meeting structural performance requirements. Automotive friction materials are mainly used to manufacture brake friction pads and clutch plates. Since these materials are primarily employed in the braking and transmission systems of vehicles, they must exhibit sufficiently high and stable friction coefficients along with good wear resistance. Motorcycles are gasoline-engine-driven vehicles with two or three wheels, steered by handlebars for front-wheel direction. They are lightweight, agile, and fast, widely used for patrols, passenger and cargo transportation, and also serve as sports equipment.

Does Installing a Rear Wing on a Regular Sedan Have Any Effect?

Installing a rear wing on a regular sedan does have an effect. When the car is traveling at high speeds, the air passing over the rear wing can increase the vehicle's downforce (generally adding several dozen kilograms of pressure, and in some cases even over 100 kilograms), improving the stability of the vehicle. Additionally, a well-designed rear wing can reduce air resistance, achieving some fuel efficiency to a certain extent. There are two methods for fixing a rear wing on a car: generally categorized as invasive and non-invasive installation. Invasive installation involves drilling holes directly into the trunk lid and then securing the wing with screws. If not handled properly, this method can easily lead to rusting of the vehicle's body panels.
