An engine light on the car indicates that there is a problem with the engine. The possible causes are: 1. Sensor malfunction causing the car's ECU to fail to accurately obtain engine data; 2. Carbon buildup in the engine; 3. Faulty spark plugs, ignition coil failure, fuel pump malfunction, or clogged fuel lines leading to incomplete combustion of the air-fuel mixture; 4. Clogged intake valves. Solutions for engine problems: 1. Remove the positive and negative battery terminals and reattach them after 20 seconds; 2. Replace spark plugs or ignition coils; 3. Replace the air filter and clean the throttle body and fuel lines; 4. Use high-quality engine oil; 5. Clean carbon deposits from the engine.

What are the basic components of a car starting system?

The basic components of a car starting system include the car battery, ignition switch, starting relay, starter motor, and fuses. The main function of the car starting system is to convert the electrical energy from the battery into mechanical energy to start the vehicle. The starter motor is primarily activated by external force, and currently, most starters on the market are electric starters, which are characterized by easy operation and relatively fast starting speed. Starters can be categorized by transmission method into inertia-engagement starters and armature-movement starters, and by control mechanism into mechanically-operated starters and electromagnetically-controlled starters. Starters are generally not prone to damage, but it is still important to inspect and maintain them during regular vehicle maintenance.

How often should the engine timing belt be replaced?

Engine timing belts generally need to be replaced every 3 to 5 years or approximately every 80,000 to 100,000 kilometers. The specific replacement interval depends on the actual usage conditions of the vehicle. If the car is often driven with light loads, the belt can be inspected around 80,000 kilometers and may continue to be used if no issues are found, with replacement recommended between 100,000 to 130,000 kilometers. For vehicles frequently carrying heavy loads or subjected to strenuous driving conditions, the belt experiences greater wear and should be inspected around 60,000 to 80,000 kilometers, with replacement at 100,000 kilometers. As a rubber component, timing belts have a limited service life. Prolonged use leads to natural aging, surface hardening, and cracking. Additionally, since timing belts operate continuously at high speeds, they are prone to wear and potential failure.

What maintenance items should be performed at 20,000 kilometers for a car?

The maintenance items to be performed at 20,000 kilometers for a car include changing the engine oil, oil filter, air filter, cabin air filter, spark plugs, etc. The function of the air filter is to block dust and particles inhaled by the engine during the intake process. If the filter is not cleaned for a long time, it will cause the engine to inhale dust, resulting in abnormal wear of the cylinder walls. If it was not replaced during the 10,000-kilometer maintenance, it must be replaced at the 20,000-kilometer maintenance. If the car uses ordinary material spark plugs, then preparations should also be made to replace them at 20,000 kilometers. Spark plugs directly affect the engine's acceleration performance and fuel consumption. When you feel the engine's power is insufficient while driving, maintenance should be performed.

Which button should I press to defog the car windows?

Press the defog button, turn on the air conditioning (A/C), set the temperature to the lowest, and switch to external circulation to defog the windows. Both cold and warm air can be used to defog the car windows, but warm air is slower than cold air. The most effective method is using cold air, which blows dry cold air directly onto the glass, preventing water vapor from condensing on the glass and achieving defogging. The method of using warm air is similar to cold air, but note that warm air should not be used on rainy days as it may initially worsen the fog. Always use external circulation when defogging car windows. The reason for car window fogging: There is a temperature difference between the inside and outside of the car. If the temperatures inside and outside the car are different, the surface with the lower temperature will have a lower saturated vapor pressure than the surrounding environment, causing water vapor to gather on the glass surface and form tiny water droplets, resulting in fog. Methods to defog car windows: For manual air conditioning, open the front window defogging mode, set the fan speed to maximum, turn on the A/C, and adjust the temperature to the lowest. Wait a moment, and the fog on the windows will disappear. Some models are equipped with rear window electric heating and external rearview mirrors; pressing the button will remove the fog in about a minute. For automatic air conditioning, usually just press the one-touch defrost button, set the fan speed to maximum, and turn on external circulation. The fog on the car windows will disappear shortly. Air conditioning cooling: Use the air conditioning's dehumidification function to reduce air humidity and remove fog. In summer, especially when multiple people enter the car without turning on the air conditioning promptly, the exhaled air has high humidity, quickly causing the windshield to fog up. Turning on the air conditioning to blow cold air onto the windshield and using the dehumidification function can quickly remove the fog. If the humidity is too high and the air conditioning is ineffective, slightly opening the window can quickly reduce the humidity inside the car. Combining this with the air conditioning will yield faster results. Air conditioning heating: Use warm air to reduce the temperature difference and remove fog. In winter, blowing warm air onto the glass quickly raises the temperature of the front glass, reducing the temperature difference between the inside and outside surfaces of the window, thereby preventing heavy fogging. However, the rear and side windows heat up more slowly, so it takes longer to remove all the fog. Whether using automatic or manual air conditioning, turning on the air conditioning helps with dehumidification. Avoid setting the air conditioning temperature to the coldest, as prolonged use may cause the outer surface of the windshield to fog up. Applying anti-fog spray for prevention: Spray a small amount of defogging agent on the car windows and wipe it clean to remove dirt and stains. While polishing the glass, a thin transparent protective film forms, effectively preventing water vapor from condensing into fog, especially suitable for cold winters. Alternatives to defogging agents include dish soap, soapy water, glycerin, alcohol, or saline solution. After drying, wipe off excess fibers with chamois or a soft dry cloth, ensuring the windows remain fog-free for several days. Opening windows for air circulation: If the fog inside the car is not heavy, opening the windows on both sides allows air to circulate between the inside and outside, reducing the temperature difference and gradually eliminating the fog. This method works on the same principle as using cold air from the air conditioning. However, this method has obvious drawbacks and cannot be used during rain, snow, on highways, or when the fog is heavy.

What is the reason for abnormal noise when starting the car?

The reasons for abnormal noise when starting the car: 1. The sound of the timing chain; 2. Insufficient lubrication during cold start, resulting in friction noise from metal parts; 3. The sound produced by the slipping of the motor belt during cold start. Check the tightness of the motor belt and see if there is any aging; 4. Poor retraction of the starter; 5. The battery has issues, either it is undercharged or its lifespan has expired. For example, forgetting to turn off the headlights when parking or not turning off the car's electrical appliances, leading to undercharging. In such cases, the battery needs to be replaced. It is recommended to go to a 4S shop or a professional auto repair shop promptly for the technician to inspect and determine the problem before carrying out the appropriate repair.
