What are the common faults of wipers?

Common faults of wipers are introduced in detail as follows: 1. Streaks: The optimal support point of the wiper arm is not found, causing the wiper blade not to fully contact the glass at every part. 2. Water droplets: After the wiper sweeps the windshield, small water droplets still adhere to the glass surface. 3. Wiper lifting phenomenon: When the car is driving at high speed, the wiper is lifted by the wind force, resulting in some areas not being swept. 4. Blade hardening: Due to direct sunlight and high temperature, the wiper blade hardens and loses elasticity. 5. Corrosion or blade wear: Poor climate, improper use of cleaning products, or substandard blade formula cause the edge of the wiper blade to be damaged or completely worn. 6. Foggy streaks: Caused by dirt, grime, or car wax adhering to the glass; contamination of the wiper blade by car wax or oil can also cause this phenomenon. 7. "Click" sound or harsh noise: Irregular wiper sweeping is mostly caused by blade wear, damage to the arm and bracket, or aging and deformation of the blade. 8. Blade cracking: The blade has a certain lifespan, and after exposure to cold, heat, acid, and alkali, it hardens, cracks, or peels. 9. Upper structure damage: Damage caused by ice scrapers or external force, resulting in structural damage to the wiper arm. 10. Blade contamination: Mostly caused by long-term accumulation of oil stains or car wax on the wiper, creating gaps between the wiper and the windshield, preventing complete water removal.

How Does an Oxygen Sensor Work?

For more information on how an oxygen sensor works, the details are as follows: 1. The working principle of an oxygen sensor is similar to that of a dry cell battery, with the zirconia element in the sensor acting like an electrolyte. Its basic working principle is: under certain conditions (high temperature and platinum catalysis), the difference in oxygen concentration on the inside and outside of the zirconia generates a potential difference, and the greater the concentration difference, the greater the potential difference. The oxygen content in the atmosphere is 21%. The exhaust gas from burning a rich air-fuel mixture contains virtually no oxygen, while the exhaust gas from burning a lean air-fuel mixture or due to misfire contains more oxygen, but still much less than that in the atmosphere. 2. Under high temperature and platinum catalysis, negatively charged oxygen ions adsorb on the inner and outer surfaces of the zirconia sleeve. Since there is more oxygen in the atmosphere than in the exhaust gas, the side of the sleeve exposed to the atmosphere adsorbs more negative ions than the exhaust side, creating an electromotive force due to the difference in ion concentration between the two sides. When the oxygen concentration on the exhaust side of the sleeve is low, a high voltage (0.6 to 1V) is generated between the electrodes. This voltage signal is sent to the ECU for amplification and processing. The ECU interprets a high voltage signal as a rich air-fuel mixture and a low voltage signal as a lean air-fuel mixture. Based on the oxygen sensor's voltage signal, the computer adjusts the air-fuel mixture to be as close as possible to the theoretically optimal ratio of 14.7:1 by diluting or enriching the mixture. Therefore, the oxygen sensor is a key sensor for electronic fuel metering. The oxygen sensor can only fully exhibit its characteristics and output voltage when it is at a high temperature (the tip reaches above 300°C). At around 800°C, it reacts most quickly to changes in the air-fuel mixture, while at low temperatures, this characteristic changes significantly.

What materials are needed for the first maintenance of Changan CS55?

Items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle registration book; vehicle purchase invoice. Bring these to the designated first maintenance facility for the vehicle's initial service. Important note: Schedule an appointment with the 4S store in advance. The first maintenance refers to the initial service after a new car has been driven. The specific timing varies by vehicle, typically after driving 5,000 kilometers or 6 months. It's crucial to attend the first maintenance on time, neither early nor late. The completion of the first maintenance signifies the end of the vehicle's break-in period, allowing it to be driven under standard load and normal speed as required by the car. The timing for the first maintenance is calculated from the date of vehicle pickup. There are two indicator values for the first maintenance: mileage and time. Whichever indicator is met first will be the standard. First maintenance tasks include: changing the engine oil and oil filter, cleaning the air filter, checking various fluid levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and inspecting tires for damage or bulges. Time required: Completing all tasks takes approximately 2 hours. The most important aspect of a new car's first maintenance is changing the engine oil and oil filter. When changing the oil, the oil filter must also be replaced. The choice of oil must refer to the "Vehicle Usage and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not wash the interior of the car with water: Many people clean their cars during holidays, washing the exterior with water and wiping it with a cloth. It's important to note that the interior should not be washed directly with water. If the floor mats are dirty, use a vacuum cleaner or take them out to brush with detergent, dry them, and then put them back. There are many holes under the rubber mats on the driver's side floor. If water enters, it won't dry but will flow through these holes to areas like the gearbox, causing erosion and corrosion. The best practice is to vacuum clean first and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the car's antifreeze is low, it's recommended to drain the existing antifreeze and add the same brand from the start. Different brands of antifreeze have varying chemical properties and use different corrosion inhibitors. Mixing them can lead to unnecessary problems. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function properly again. Some people apply lubricant to bolts and nuts to prevent rust, but this introduces unnecessary risks to safe driving. At high speeds, bolts and nuts can easily loosen or even fall off, leading to driving malfunctions.

What powers the windshield wipers?

The power source of the windshield wipers comes from an electric motor, which serves as the core of the entire wiper system. The quality requirements for the wiper motor are very high, as it utilizes a DC permanent magnet motor. The wiper motor installed on the front windshield is integrated with the worm gear mechanical assembly. The function of the worm gear mechanism is to reduce speed and increase torque. Its output shaft drives a four-bar linkage mechanism, which converts continuous rotational motion into a side-to-side oscillating motion. Automotive windshield wipers, also known as wipers, are devices used to sweep away raindrops and dust adhering to the vehicle's windshield, thereby improving the driver's visibility and enhancing driving safety.

What is the engine RPM when the car speed is 70 km/h?

When the vehicle speed is 70 mph, which is approximately 113 km/h, the engine RPM is around 2600. Here are some relevant information: 1. The engine RPM is influenced by two main factors: the engine displacement and the transmission. At the same speed, a larger engine displacement results in lower RPM. 2. Both excessively high and low RPM are generally not good. If the RPM is too low, the gasoline may not burn completely, leading to rapid accumulation of carbon deposits in the vehicle. If the RPM is too high, it can accelerate the natural wear of the engine cylinders, shortening the engine's lifespan.
