What Causes Belt Squealing?

What is the reason for the failure of the wiper not moving in the first gear?

The reason is that the gear shaft of the wiper motor is rusted, causing the first gear to fail to rotate, and the plastic gear will quickly wear out and become unusable. Additionally, the circular contact plate paired with the gear may also rust, leading to poor contact in the first gear of the wiper, preventing it from rotating. Here are some extended details: 1. Wiper: The wiper is a plastic product. Parking the car in a shaded area can help extend the lifespan of the wiper. A good wiper must have characteristics such as heat resistance, cold resistance, acid and alkali resistance, corrosion resistance, the ability to fit the windshield, reduce the burden on the motor, low noise, strong water repellency, and softness to avoid scratching the windshield, ensuring clear visibility for the driver. 2. Types of wipers: There are roughly two types of wipers. One is the traditional intermittent type, which is the most common wiper, available in three to four segments, allowing the driver to adjust according to the rain intensity and visibility conditions. The other type is the rain-sensing wiper, mostly used in mid-to-high-end vehicle models.

What does EPC displayed on the vehicle mean?

The EPC indicator light has two activation states: self-check illumination during power-on and illumination under other circumstances. The power-on self-check is an indication that the vehicle is monitoring the status of all sensors before driving. Generally, if the engine is not started after power-on, the light will turn off by itself after about 3 seconds. In other cases, if the EPC indicator light remains illuminated after the vehicle starts or does not turn off for an extended period, the main causes may include faults in the engine intake system, throttle valve, fuel system, engine, ECU control unit, or brake lights. Below is a detailed explanation of the reasons for the EPC light illuminating under other circumstances: Engine intake system fault: The EPC light will activate if the engine intake is obstructed or insufficient. Throttle valve fault: Carbon buildup is a common issue with the throttle valve. Additionally, dirt accumulation can affect intake, triggering the indicator light. Fuel system fault: Examples include substandard fuel, fuel deterioration, or poor fuel atomization. Engine fault: Insufficient engine pressure or issues with components like the intake valves in the powertrain can also cause the EPC light to activate. ECU control unit fault: This may involve signal interference in the vehicle's computer or false alarms. Brake light fault: Situations such as brake lights not working, faulty brake switches, or brake circuit issues. Solutions for when the EPC indicator light illuminates: Troubleshoot intake system issues, use fuel with the appropriate octane rating, clean the throttle valve, etc. Remove carbon deposits from relevant components. Re-flash ECU-related data. If the EPC light illuminates, the owner can first try turning off the engine and restarting it to check if the EPC light remains on. If it does not, there may be no issue, possibly just interference affecting the indicator. If the EPC light stays on or frequently illuminates, the vehicle should be taken to the nearest service point for professional diagnosis and repair to eliminate potential safety hazards. The full English name of EPC is Electronic-Power-Control, which translates to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system primarily includes controllers and sensors related to the powertrain. When sensor data in the system is abnormal, the EPC system will take predefined actions to address powertrain issues. Common EPC indicator lights are usually displayed in two colors: yellow and red. A yellow EPC fault light indicates the vehicle can still be driven, but it should proceed slowly to a repair point for inspection. A red EPC fault light signifies a more serious issue, and the vehicle should be pulled over immediately, with professional repair services contacted. Continuing to drive under such conditions may directly affect core components or driving safety.

Which Spark Plug Material is the Best?

Spark plugs generally come in the following four materials: 1. Nickel Alloy: Nickel alloy is an excellent material for spark plug electrodes due to its strength, hardness, electrical resistance, melting temperature, and corrosion resistance. However, nickel alloy tends to accumulate carbon deposits easily. To extend its service life, the electrode surface is usually made larger, which increases the time before it gets covered by carbon deposits, thereby prolonging its lifespan. 2. Iridium: Iridium spark plugs have high arc intensity, high temperature, and fast response, making them less prone to carbon buildup. This allows the electrodes to be made much smaller than those of ordinary spark plugs. Therefore, iridium spark plugs have significant advantages. Their high melting point enables them to be used in various high-power engines, tolerating higher temperatures without electrode melting or burning out. 3. Platinum: This type of spark plug is a balanced option, with performance similar to iridium spark plugs. However, its lifespan is slightly longer, typically lasting 50,000-80,000 kilometers. 4. Iridium-Platinum: This is the best material among single-electrode spark plugs, with performance surpassing both iridium and platinum. Also known as double iridium, its stability is more outstanding than platinum, and it has the longest lifespan among the four materials, lasting up to 100,000 kilometers.

What Are the Effects of Starting the Car Without Turning It Off First?

Restarting the car while the engine is already running has almost negligible effects on the engine itself, but it can have some impact on the flywheel teeth and the starter motor. However, occasional mistakes in operation will not cause significant damage or lead to component failure. Here are some key points to note when starting a car: 1. First Look: Walk around the car to inspect its exterior and surroundings. Check for any obstacles in front or behind the vehicle, any suspicious oil or water stains on the ground where the car is parked, whether the front and rear light assemblies are damaged, and if the tire pressure is adequate. 2. Second Check: Verify that the engine oil and coolant levels are sufficient, and ensure that the front and rear lights, signal lights, and dashboard are functioning properly. This step mainly involves checking the car's internal technical condition. Lift the hood, pull out the dipstick to check if the oil level is normal, and unscrew the radiator cap to inspect the water level. 3. Starting: If the first two steps are normal, turn the ignition key to start the engine. Each start-up should not exceed ten seconds. It is important to note that when starting a cold engine, the throttle should be pressed gently and gradually. Avoid immediately accelerating sharply after starting, as this can cause the engine speed to rise rapidly. During a cold start, the crankshaft speed increases suddenly, and the oil may not reach the bearing positions in time, potentially causing bearing damage.
