Why does the car still go so fast when the clutch is fully depressed?

Because the previous state was acceleration, fully depressing the clutch means the power supply is cut off. However, on flat ground or downhill, the car will first deplete the acceleration from the previous process before it starts to decelerate. Here is some related knowledge about depressing the clutch: 1. Principle: It's quite simple, it's about the interaction of forces. Before depressing the clutch, the gear output force drives the wheels forward, providing both forward momentum and resistance since the wheels are connected to the gear. When the clutch is depressed, although the power is cut off, the resistance is also eliminated. Therefore, on relatively flat roads, there might be a temporary speed increase. If going downhill, the car will roll even faster, but coasting downhill is too dangerous and should be avoided. 2. Clutch Introduction: The function of the clutch is to disconnect the engine from the wheels. In other words, fully depressing the clutch means the engine is idling, and the wheels receive no driving force. When starting, depressing the clutch completely separates the engine from the wheels, and the car won't move as the engine idles. At high speeds, when the throttle is not pressed, the engine is actually being turned by the wheels. Depressing the clutch at this time removes the engine's resistance.

Is it a problem if the side of the tire has a small cut?

Generally, it's not a big issue. However, it's best to inspect the side carefully. Here is some relevant knowledge about tire sidewall damage: 1. Introduction The weakest part of a tire is the sidewall. Most tires only have one or, in rare cases, two thin layers of fabric reinforcement. If the sidewall is deeply damaged or shows signs of bulging, it is recommended to replace the tire promptly to prevent a blowout. If the spare tire is full-size, you can purchase a new one and use it on the same axle as the spare. It is essential to choose a tire of the same brand, model, size, tread pattern, and grade. For non-full-size spare tires, the tread wear should be roughly consistent. When the original tire's tread wear is excessive, it is advisable to buy a pair of new tires for replacement. It is recommended to install the new tires on the rear axle, as this helps prevent oversteer at certain speeds, making it easier to control the vehicle and avoid skidding or loss of control. 2. Replacement requirements: The weakest part of a tire is the sidewall. Most tires only have one or, in rare cases, two thin layers of fabric reinforcement.

It is recommended to install the new tires on the rear axle, as this helps prevent oversteer at certain speeds, making it easier to control the vehicle and avoid skidding or loss of control. Additionally, in rainy or snowy weather, insufficient rear tire grip can cause drifting, while insufficient front tire grip can usually be corrected by steering, but rear tire grip loss is generally harder to control.

Where to Go for Car Viewing When Buying a Car?

You can visit local 4S stores for car viewing. Here are some considerations when viewing cars: 1. Budget: Prepare a budget in advance. When selecting a vehicle, check the engine number to avoid purchasing a refurbished car. 2. Test Drive: During a test drive, you can assess how easy it is to operate the vehicle, as well as the noise insulation and shock absorption effects, which can be immediately felt while driving. Besides the driver's comfort, the sense of space in the rear seats and the comfort of the seats are also very important. Experience the rear seating space to see if there's any sense of confinement, whether the interior materials feel low-grade, and if the design is reasonable. 3. Pricing: You can inquire in advance with the salesperson about any discounts or promotional activities. Cars often come with promotions. When asking about the price, clarify whether it's the ex-factory price or the on-the-road price to avoid exceeding your budget. Also, ask how many free maintenance services are included.

What does 'American valve' mean in tires?

New-style valves generally refer to American valves, which have a thicker valve head. Below is a relevant introduction about car tire valves: 1. French valve: Manually locks the valve, withstands high pressure, has a smoother air leakage curve, features a thinner valve base, is lightweight, has a small valve diameter, minimally affects rim strength, can be used with 19C-sized inner tubes or narrow rims, and is more expensive. 2. American valve: Primarily relies on internal pressure to lock, withstands high pressure, has a steeper air leakage curve (meaning it leaks faster when pressure is insufficient), features a larger valve base and diameter, but offers high inflation flow, making it widely used in inner tubes with larger air volumes, thus making inflation very convenient. 3. English valve (Chinese-style valve): Uses a rubber sleeve for leak prevention, with leak-proof performance mainly dependent on the quality of the rubber sleeve, offering excellent airtightness (some riders might think English valves leak quickly, but if the rubber tube isn't damaged, it's not the valve's fault—it's usually because English valve inner tubes use regular rubber instead of butyl material). However, it has low pressure resistance, a large valve base, is heavy, has low inflation flow, poor durability of the rubber sleeve, but is easy to repair, doesn't render the inner tube unusable due to valve issues, and is inexpensive.

Can You Always Park Where There Are Parking Lines on the Roadside?

You can park where there are parking lines on the roadside unless there are special signs prohibiting it. Here is some relevant information about roadside parking: 1. Basis: Parking is allowed where there are parking lines on the roadside. However, white dashed lines on pedestrian crossings indicate no parking, as pedestrian crossings are designated for pedestrians and parking is prohibited. According to Article 33 of the Road Traffic Safety Law of the People's Republic of China, new, renovated, or expanded public buildings, commercial districts, residential areas, and large (medium)-sized buildings should be equipped with or have additional parking lots. If parking spaces are insufficient, timely renovations or expansions should be carried out. Parking lots in use must not be arbitrarily closed or repurposed. Within urban road areas, government authorities can designate parking spaces as long as they do not obstruct pedestrians or vehicles. 2. Requirements: If the driver is not present or refuses to leave immediately, the vehicle must not hinder the passage of other vehicles or pedestrians. The vehicle may be towed to a location that does not obstruct traffic or to a place designated by the traffic management department of the public security authority. The traffic management department must not charge the vehicle owner for towing and should promptly inform the owner of the parking location. If the vehicle is damaged due to improper towing methods, compensation must be provided according to the law.

Can a Refrigerated Box Be Converted into a Box Truck?

No, the original structure of a vehicle cannot be altered arbitrarily. It is recommended to purchase a professional refrigerated truck. Below is some relevant knowledge about vehicle modifications: 1. Exterior Modifications: The modification of a vehicle's exterior has always held significant importance. Common exterior modifications include decals, body painting, emblems, front and rear bumpers, body kits, high rear wings, vented hoods, window rain guards, HID xenon headlights, headlight decorative panels, front and rear perspective mirrors, and lowering the vehicle's height. 2. Handling Modifications: Chassis modifications involve the suspension, shock absorbers, transmission, brakes, tires, and rims. Factory-installed suspensions are generally softer to prioritize ride comfort. However, overly soft suspensions can cause excessive body roll during aggressive cornering, leading to instability and reduced cornering performance, or even loss of control in severe cases. Therefore, chassis modifications must include reinforced suspensions and shock absorbers. Professional racing modifications often opt for extremely stiff shock absorbers to maximize cornering limits. For civilian vehicles, overly stiff shock absorbers can make the ride uncomfortably bumpy for daily use. Thus, many shock absorber manufacturers now offer products that balance comfort with improved cornering performance to cater to the civilian modification market. 3. Performance Modifications: Like the human heart, the engine is the heart of a car and the most critical component. Engine modifications are also the most complex. The primary goal is to increase output power through methods such as enlarging cylinder bores, increasing compression ratios, adding more valves, or converting from naturally aspirated to turbocharged setups. However, it is crucial to note that engine modifications are highly risky. A slight mistake can damage the engine or even lead to serious safety incidents.
