Can a Plug-in Hybrid Still Drive When It Runs Out of Battery?

Plug-in hybrids can still run when they run out of battery, as these vehicles can rely on the internal combustion engine to drive. Both plug-in hybrid vehicles and pure electric vehicles are eligible for the new energy green license plates. The government has regulations for plug-in hybrid vehicles, stipulating that such vehicles must have a pure electric range of over 50 kilometers to qualify for the green new energy license plate. The differences between plug-in hybrids and regular hybrid vehicles are: 1. Plug-in hybrid vehicles require charging the battery; regular hybrid vehicles do not need to charge the battery. 2. Plug-in hybrid vehicles have a longer range. Most pure electric vehicles have a relatively low range, and it takes a long time to fully charge the battery, which is a major reason why many consumers avoid purchasing pure electric vehicles.

How Often Should Car Brake Pads Be Replaced?

Car brake pads are typically replaced every 50,000 kilometers, with inspections recommended every 5,000 kilometers. Brake pads generally consist of two parts: an iron backing plate and friction material. New pads have a thickness of 14 millimeters, while the replacement limit is 7 millimeters. Pads that have reached the usage limit must be replaced immediately, as continuing to use them will reduce braking effectiveness and compromise driving safety. When replacing, always use original equipment manufacturer (OEM) brake pads to ensure optimal braking performance between the pad and rotor. Special tools must be used to retract the brake caliper piston during replacement - never force it back with pry bars. After installation, pump the brakes several times and allow a 200-kilometer break-in period for the pads to achieve optimal braking performance.

What to Do When the Car Door Won't Open and the Key Won't Turn?

Here are the reasons and solutions for when the car door won't open and the key won't turn: 1. Incorrect operation, such as turning the key in the wrong direction. In most cases, turning the key clockwise unlocks the door, while turning it counterclockwise locks it. For specific operations, refer to the car's user manual, which will provide detailed instructions. 2. The lock cylinder is faulty. Most car owners use remote keys to open or lock the doors and rarely use mechanical keys. Due to prolonged disuse, the lock cylinder may rust. Try adding some engine oil to the lock cylinder to lubricate it and see if it can be opened. If it still doesn't work, the lock cylinder may need to be replaced. 3. The mechanical key is faulty. In most cases, the mechanical key won't have major issues. If there is a problem, it might be due to a poorly duplicated key. In such cases, the key needs to be re-duplicated. 4. On cold winter mornings, sometimes the mechanical key won't turn when trying to open the door. This is usually caused by residual water from washing the car entering the keyhole. When the key is inserted, the locking mechanism inside fails to release, preventing the key from turning. Avoid applying excessive force, as this could damage or deform the key, making it unusable. Wait for the moisture to dry, and the issue should resolve itself. 5. The car is in a locked state. Wait for one or two hours until the lock is released, then try unlocking again. Some car models, when in anti-theft lock mode, not only lock the engine but also prevent the mechanical key from opening the doors via the central locking system.

What Causes Vehicle Body Vibration?

Possible reasons for vehicle vibration during driving include: severe engine carbon deposits, aging engine components, ignition system issues, etc. Detailed explanations are as follows: 1. Severe engine carbon deposits: The most common cause of vehicle vibration is a dirty throttle body or excessive carbon buildup in the fuel injectors. When there is too much carbon deposit inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start the engine. In this situation, the engine can only start easily after the carbon deposits have absorbed enough gasoline to reach saturation. Once started, the gasoline adsorbed on the carbon deposits will be drawn into the combustion chamber by the engine's vacuum suction, causing the air-fuel mixture to become too rich. The constantly fluctuating air-fuel mixture leads to idle vibration after a cold start. 2. Aging engine components: Vehicle vibration can also be related to worn engine mounts. Engine mounts act as the shock absorption system for the engine, responsible for absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations will be transmitted to the steering wheel and the cabin, causing vibrations during idle. 3. Ignition system issues: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or weak spark plug firing can also lead to such symptoms.

Does Changing the Engine Affect the Car?

Generally, replacing the engine in a car does not affect the vehicle as a whole, as long as the installation is done correctly. Apart from the engine, components such as the transmission, drive axle, steering mechanism, and braking system typically remain untouched. However, the new engine will require a break-in period. Here is some information about engine replacement: 1. If the engine is damaged due to lack of oil or water, leading to issues like cylinder scoring, bearing failure, or valve damage, whether you replace it with a brand-new or a used engine, you must register the change with the vehicle management office within ten days. 2. When replacing the engine, if you are installing a brand-new engine, it is essential to check whether the packaging is intact, whether there is a valid motor vehicle safety technical inspection certificate, and whether the interior of the engine is clean and tidy. Most importantly, after replacing the engine, be sure to use high-quality engine oil and follow the required break-in procedures.

How to Deal with Foggy Car Windshield?

Here are the solutions for a foggy car windshield: 1. Open windows for air circulation: If the fog inside the car is not heavy, you can slightly open the windows on both sides to create airflow between the inside and outside of the car. This reduces the temperature difference and gradually dissipates the fog. The principle is similar to using the air conditioner's cold air, but this method doesn't increase fuel consumption. However, the downside of opening windows is obvious—it's not suitable during rain, snow, on highways, or when the fog is heavy. Additionally, it lowers the temperature inside the car. 3. Air conditioning system: Almost all cars nowadays have air vents located under the front windshield. Simply adjust the air conditioner to the appropriate setting to use the airflow to defog. If you're in a hurry, you can use cold air as an emergency measure, but in most cases, warm air is recommended for defogging. Warm air is more effective than cold air, but since the car's water temperature is low when first started, it takes some time for the air conditioner to blow warm air. Therefore, this method takes longer than using cold air. Initially, the fog inside the car may worsen due to the increased temperature difference, but once the warm air dries the moisture inside, the fog will disappear. If using this method, make sure to defog with warm air before driving and wait until the fog is completely gone. 4. Anti-fog products: There are many specialized anti-fog products available on the market, such as anti-fog sprays or fog-resistant cloths. Spray these products onto the inner surface of the car glass and wipe them clean. In addition to removing dirt, they form a thin transparent protective film that prevents moisture from condensing into fog on the glass. One application can last about ten days to half a month.
