What is the appropriate speed for breaking in a new car?

During the break-in period of a new car, the speed should generally be maintained between 50-90km/h. Here are some precautions to note during the break-in period: Avoid high-speed driving: Try not to let the car's speed reach 120km/h, as this helps maintain the engine's performance and prolong its lifespan. Avoid overloading: Placing excessively heavy objects in the car during the break-in period undoubtedly puts stress on the vehicle. Overloading often requires frequent gear changes, and the constant shifting between high and low gears can be very detrimental to the engine. Avoid driving on extremely poor road conditions: Driving on very rough roads during the break-in period can cause significant tire wear. Moreover, prolonged driving under such conditions with the engine constantly operating at high power can inevitably lead to damage.

Do You Need to Press the Brake When Using One-Button Start/Stop?

Cars equipped with a one-button start system do not require pressing the brake pedal when shutting off the engine. Below are the related explanations for one-button start/stop issues: Idle Switch Not Closing: If the engine speed does not increase when the air conditioning is turned on at idle, this fault can be confirmed. The throttle position sensor can be adjusted, repaired, or replaced. Idle Control Valve Malfunction: Check for any operational sound from the idle control valve. If there is no sound, it indicates a malfunction. The idle control valve can be cleaned or replaced, and the idle speed should be reset using a dedicated decoder. Intake Pipe Leakage: If a hissing sound from the intake pipe is heard, it indicates a leak in the intake system. The leak should be located and resealed or the relevant components replaced.

At what position on the pressure gauge is the fire extinguisher's pressure considered normal?

The normal pressure value is indicated by the green zone on the gauge, with pressure approximately between 1.2—1.5 MPa. Here are the relevant explanations: 1. When the pointer is in the red zone: This indicates insufficient pressure inside the cylinder, rendering the fire extinguisher unusable and requiring replacement. 2. When the pointer is in the yellow zone: This signifies excessive pressure, posing a potential hazard, and the extinguisher should be sent to a specialized facility for inspection and repair. 3. Once a fire extinguisher has been activated: Even if only a small amount has been discharged, it must be refilled according to specified requirements. Refilling should be performed by professional maintenance departments following the manufacturer's prescribed methods and requirements. Alterations to the type of extinguishing agent, weight, or driving gas pressure are not permitted.

What are the reasons for the engine malfunction indicator light being on and the car shaking?

The reasons for the engine malfunction indicator light being on and the car shaking are: 1. Poor gasoline quality leading to incomplete combustion of the air-fuel mixture in the cylinder, resulting in carbon deposits; 2. Excessive engine mileage causing weakened spark plug performance; 3. Vehicle mechanical aging or damage; 4. Sensor or computer board malfunction. Hazards of the engine malfunction light being on: 1. Deterioration in the quality of vehicle exhaust emissions, polluting the environment; 2. Increased combustion chamber temperature and accelerated wear, leading to engine damage; 3. Causing the engine to burn oil; 4. Increased engine noise, affecting driving and passenger comfort. The function of the engine: To convert the thermal energy of gasoline into mechanical energy by burning and expanding gas in a sealed cylinder, thereby pushing the piston to perform work.

How Long Does It Take to Repair a Flat Tire?

The time required for tire repair depends on the extent of the tire damage, typically ranging from twenty to thirty minutes. Severe damage may prolong the process. Always inspect your vehicle before driving and address any issues promptly. Never drive a vehicle with safety hazards on the road—safety comes first. Below are several tire repair methods: 1. Cold Patching: The most common internal repair method, which involves removing the tire with a tire changer. 2. Hot Patching: This method involves a secondary process on top of cold patching, using a heating machine to thermally treat the patched area for better adhesion inside the tire. 3. Mushroom Plug: The most durable and reliable method. The mushroom plug, resembling a mushroom, is inserted from the inside out through the puncture, secured, and then glued inside. The excess part is trimmed off. 4. Automatic Tire Sealant: An emergency solution where the sealant is shaken well and sprayed directly into the tire through the valve stem. The sealant flows to the damaged area and seals it automatically.

Can Windshield Washer Fluid Be Replaced with Mineral Water?

Windshield washer fluid should not be replaced with mineral water. Below is an introduction to the functions of automotive windshield washer fluid: Cleaning Performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving cleaning and stain removal effects. Antifreeze Performance: It can significantly lower the freezing point of the liquid, providing antifreeze protection and quickly dissolving frost. Anti-Fog Performance: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear field of vision. Anti-Static Performance: After cleaning with windshield washer fluid, substances adhering to the glass surface can eliminate static charges on the glass, providing anti-static properties.
