Methods for removing engine carbon deposits are as follows: 1. Use an intravenous drip method by cutting off the fuel supply and connecting a carbon deposit cleaner to the engine fuel injector. The cleaner softens the carbon deposits inside the engine, allowing them to be burned and emitted. However, this method is only suitable for slight carbon deposits and is ineffective for vehicles with severe carbon buildup. 2. Disassemble the engine intake manifold for cleaning. Remove the engine intake manifold, scrape off stubborn carbon deposits, and reassemble after cleaning for better results. 3. Drive more long-distance or high-speed trips. The vehicle hardly produces any carbon deposit adsorption in a hot state, and the high-speed operation of the engine can expel some carbon deposits.

Where is the clutch and brake located?

The clutch is the first pedal from left to right, and the brake is the second pedal from left to right; manual transmission cars have three pedals, arranged from left to right as the clutch pedal, brake pedal, and accelerator pedal. Normally, the left foot controls the clutch, while the right foot controls the brake and accelerator. The clutch pedal is used to engage and disengage to transmit an appropriate amount of power. The clutch consists of friction plates, spring plates, pressure plates, and a power output shaft, and is located between the engine and the transmission. It transmits the torque stored on the engine flywheel to the transmission, ensuring that the vehicle delivers the appropriate driving force and torque to the drive wheels under different driving conditions, falling under the category of the powertrain.

What does the AVH Auto Hold System mean

Auto Hold refers to an automatic braking function. After activating this feature, such as when stopping at a traffic light, it eliminates the need to pull the handbrake, simplifying operations by avoiding the use of manual or electronic parking brakes. For automatic transmission models, it also reduces the need for frequent shifting between D to N or D to P. The functions of the Auto Hold system include: 1. Preventing rollback: When stopping briefly at a traffic light, the system automatically applies the brakes to the wheels after the vehicle comes to a complete stop to prevent rolling. 2. Preventing backward sliding: During uphill starts, the system automatically brakes to prevent backward sliding, and releases the wheels automatically when starting to move forward. 3. Automatic braking: Some models automatically apply the brakes to the wheels when the vehicle is parked and locked, eliminating the need to pull the handbrake. Working principle of Auto Hold: When the vehicle is temporarily stopped and needs to restart shortly after, the parking function is handled by the ESP-controlled brakes. The computer uses a series of sensors to measure the vehicle's levelness and wheel torque, determines any tendency for the vehicle to move, and applies an appropriate braking force to the wheels to keep the vehicle stationary. This braking force is just enough to prevent movement without being excessive, ensuring a smooth start when the accelerator is pressed again. If the temporary stop exceeds a certain duration, the braking system switches to mechanical rear-wheel parking (activating the electronic parking brake) instead of the previous four-wheel hydraulic braking. When the vehicle is ready to move forward, the electronic system detects the accelerator pedal pressure and, for manual transmission models, the clutch pedal travel to determine whether to release the brakes.

How to Handle a Car That Hasn't Been Driven for a Long Time?

Methods for handling a car that hasn't been driven for a long time: 1. Thoroughly clean the car's paint and interior before parking to prevent damage to the paint during storage. After cleaning, it is recommended to wax the car for better protection; 2. Remove the car battery to maintain sufficient charge; 3. Protect the tires. If the car remains stationary for a long time, the part of the tires in contact with the ground may deform or lose air. The owner should move the vehicle or drive it for a while; 4. Check the fluids. Cars have various fluids, and if the vehicle is parked for an extended period, it's necessary to inspect the condition of all fluids and replace them in time to prevent deterioration; 5. Find a suitable parking spot, cover the car with a car cover to properly protect the paint.
