How to Identify Good or Bad Tire Quality?

What is the incorrect statement about coasting downhill with the engine off?

About coasting downhill with the engine off, the incorrect statement is that coasting downhill uses the slope to propel the car forward, the engine does not work, which can save fuel, and should be strongly advocated. The following are detailed explanations about it: 1. Explanation one: For vehicles equipped with vacuum-assisted braking systems, turning off the engine downhill will cause the braking system to fail. 2. Explanation two: When the engine is off downhill, the vehicle cannot use engine braking. 3. Explanation three: For vehicles equipped with power steering systems, turning off the engine downhill will make the steering wheel heavier and difficult to control.

Do You Need to Stop Before Shifting from D to S Gear in an Automatic Transmission Car?

When shifting from D gear to S gear, M gear, or L gear in an automatic transmission car, you can directly engage the gear without the need to press the brake or come to a stop. Below is some relevant information: 1. Function: The S gear essentially allows the automatic transmission to drop one gear from the current position, thereby enhancing climbing power and overtaking power. You can directly switch from D gear to S gear without releasing the accelerator, pressing the brake, or stopping. 2. Precautions: However, it is important to note that prolonged use in S gear can cause the transmission to overheat and accelerate the deterioration and aging of transmission fluid. Once climbing or overtaking is completed, switch back to D gear as soon as possible, which can be done directly.

Will the barrier gate fall if the car hasn't completely passed through?

If the car hasn't completely passed through, the barrier gate will not fall. Here are detailed explanations about it: 1. Explanation one: The barrier gate is controlled by a controller, usually operated via remote control or wired control. 2. Explanation two: The core mechanism integrates four major components: worm gear reducer, torque conversion mechanism, main shaft support, and main bracket into one unit. 3. Explanation three: The motor's speed can precisely follow changes in input frequency, maintaining constant torque even during significant speed variations. Compared to other common motors with the same power and speed, it has the smallest starting inrush current and size, yet its torque is 2 to 3 times greater. Moreover, during prolonged motor stall, the operating current does not increase.

Does the handbrake of a small car brake the front wheels or the rear wheels?

The handbrake controls the rear wheels, as it typically uses a steel cable linkage connected to the rear brake shoes. Handbrake: Its professional name is the parking brake. In most light passenger cars, the handbrake uses the lever principle to pull the brake cable, locking the rear brake shoes or calipers. Foot brake: It operates through the hydraulic brake system acting on all four tires to stop the vehicle. Traditional brake systems evenly distribute the force from the master cylinder to all four wheels. However, due to variations in road conditions and the shift in the vehicle's center of gravity during deceleration, the grip between the four wheels and the road surface will differ, making this distribution less efficient in terms of braking force utilization.

Is the antifreeze for new energy vehicles specialized?

New energy vehicles require specialized antifreeze. The cooling system of electric vehicles demands higher sealing requirements than internal combustion engine cooling, so the coolant for electric vehicles must be waterless coolant, and this coolant must not be electrolytic, otherwise it can easily cause short circuits. The following are the advantages of waterless coolant: 1. Anti-corrosion: Prevents internal rusting of the engine, keeping the radiator and cooling system as good as new. 2. No or very low pressure: The cooling system operates under no or very low pressure, allowing the radiator cap to be opened at any time. 3. Increased power: Eliminates the thermal insulation layer of water vapor, resolves local overheating of the engine, and releases the engine's power. 4. Faster acceleration: Shorter acceleration distance, smoother acceleration, and more seamless gear shifting.
