What is Clutch Free Play?

Clutch free play refers to the gap between the driven disc's front and rear end faces and the surfaces of the flywheel and pressure plate after the clutch is disengaged. During clutch operation, the driven disc wears and becomes thinner, reducing the free play. If the clutch free play is too small, it can lead to incomplete disengagement. Conversely, if it is too large, the friction coefficient between the friction plate and the driven disc increases, causing accelerated wear and potential burning of the friction plate. Below are the functions of clutch free play: As the clutch disc wears and becomes thinner during use, the pressure plate and driven disc move toward the flywheel under spring pressure to compensate. This causes the inner end of the release lever to move in the opposite direction accordingly. If there is no pre-set gap, the release lever cannot move backward, preventing the clutch from fully engaging and resulting in transmission slippage. This not only reduces the clutch's torque transmission efficiency but also accelerates wear on the clutch disc, release lever end face, and release bearing. Therefore, a certain gap must be maintained during installation to ensure the clutch can fully engage and transmit torque normally even after the friction plate undergoes normal wear.

What driving mode is generally used for urban driving?

ECO mode can be selected for urban driving. Introduction to ECO mode: ECO mode is a driving mode that leans more towards fuel efficiency compared to normal D-gear driving, with relatively slower acceleration; it is another special mode besides the S-gear that emphasizes a sense of acceleration, providing car owners with an additional choice. Categories of ECO mode: ECO mode is divided into active and passive types. For models with active ECO mode, there is usually a dedicated button, or a virtual button can be set in the intelligent driving mode selection system, allowing car owners to choose whether to turn on ECO mode. Usage method: When ECO mode is activated, it reduces the response rate of power output, minimizes unnecessary fuel injection, and makes the RPM smoother. It is generally recommended for stop-and-go traffic conditions in urban areas. Under ECO mode, the throttle response is less sensitive, and the power comes more gently. Even if the accelerator is pressed deeply, the sense of push-back is barely noticeable. Besides saving fuel consumption, it also enhances the driving experience.

What Causes Severe Engine Shaking in Reverse Gear While Running Normally in Forward Gear?

The causes of severe engine shaking in reverse gear while running normally in forward gear are aging engine mounts and severe carbon buildup in the engine. Below are the relevant explanations: Aging Engine Mounts: They need to be replaced promptly. Engine mounts, made of rubber, are located where the engine and transmission connect to the vehicle body. Rubber components degrade over time with use. Severe Carbon Buildup in the Engine: The most common cause of car shaking is a dirty throttle body or excessive carbon deposits in the fuel injectors. When there's too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. This makes the engine hard to start. Under these conditions, the engine only starts easily once the carbon deposits have absorbed enough gasoline to become saturated. After starting, the gasoline adsorbed on the carbon deposits is drawn into the combustion chamber by the engine's vacuum suction, enriching the air-fuel mixture again. This fluctuation between lean and rich air-fuel mixtures causes the engine to idle roughly after a cold start.

What are the symbols for the internal and external air circulation in the Magotan?

An upward arrow coming from outside the car indicates the external air circulation symbol; an arrow inside the car indicates the internal air circulation symbol. Below are detailed explanations of the internal and external air circulation in cars: 1. External Air Circulation: External air circulation refers to drawing air from outside the vehicle, directing it through the air conditioning system for heating or cooling, and then blowing it out through the vents. Essentially, external air circulation replenishes fresh air to improve the air quality inside the car. It should be used for defrosting in winter or defogging in summer because the air drawn from outside is richer in oxygen and drier, making it more effective for defrosting or defogging. 2. Internal Air Circulation: Internal air circulation draws air from inside the vehicle, creating a cycle of airflow within the car. Its main function is to promptly and effectively prevent external dust and harmful gases from entering the car. It helps warm up the car faster in winter and cool it down quicker when the air conditioning is on in summer. It can also be used during smoggy days. Internal air circulation maintains the internal air cycle, helping to better preserve the temperature inside the car.

Is It Worth Repainting If the Hood Paint Is Chipped by a Stone?

The chipped paint on the hood needs to be touched up; otherwise, even a small damage can cause the steel plate to start rusting. By that time, even touching up the paint will hardly prevent rust. Using a touch-up pen for repainting: Car owners can first wash and dry the car, apply rust remover to the scratched area, wait 10 to 15 minutes, and then wipe off the rust remover with a tissue to prevent further rusting. When the car's hood paint is chipped by a stone, a touch-up pen can be used for repair, covering up the rice-sized mark and making it less noticeable. Although there is still a certain gap compared to the original factory paint (color difference exists), and the durability is certainly not comparable to the original factory paint, after all, the touch-up pen is only for local touch-up. Other repainting methods: When new car paint is chipped, using toothpaste for repair is very effective because toothpaste itself has a grinding function, equivalent to applying a layer of wax to the car, thus achieving a good repair effect. However, toothpaste repair can only address minor damage; it is not very effective for deeper damage. If the stone has chipped through to the primer, sheet metal and repainting treatment will be required. But this repainting project is best left to professional staff for spraying.

Where is the rear panel located?

The rear panel of a car is the rear barrier of the trunk. It refers to the surrounding area below the trunk. Generally, the original rear panel is not integrated with the frame but is welded on. Introduction to the rear panel: The rear panel is part of the body covering. Replacing it will not cause significant depreciation. The rear panel is composed of several pieces rather than being a single unit. Deformation of the spare tire floor or the rear panel has minimal impact on the car, such as not affecting the vehicle's handling performance. Repair of a damaged rear panel: Therefore, if the rear panel is damaged, it is advisable to perform sheet metal repair if possible and avoid cutting. Once cutting is involved, the car is considered to have been in an accident. If the car is classified as an accident vehicle, its strength will decrease significantly after repair, and its resale value will drop considerably. If the repair involves only hammering or frame pulling without cutting or welding, it is not considered an accident vehicle. Although sheet metal repair does not classify the car as an accident vehicle and has little impact on resale, the actual situation should be analyzed. If the damage is severe, cutting repair must be performed. Once the rear panel undergoes cutting repair, it is crucial to apply sealant to the weld points to prevent rust, as the exposed welded areas are bare cast iron without paint protection and are prone to rust over time.
