How to Disinfect the Interior of a Car?

Detailed methods for disinfecting the interior of a car are as follows: 1. Use an air purifier: An air purifier can, to some extent, prevent certain viruses and particulate matter like dust from entering the car. However, it is important to note that viruses are primarily transmitted through droplets. When coughing, sneezing, or even speaking, droplets are expelled from the mouth and nose. Therefore, relying solely on a car air purifier to filter harmful substances does not completely block viruses. 2. Maintain ventilation: The Chinese Center for Disease Control and Prevention has provided the following recommendations for protecting private cars during the pandemic: in open areas, ensure ventilation and air exchange; in enclosed environments, close the windows and doors while turning on the air conditioning in recirculation mode. However, when opening windows for ventilation in winter, be cautious to prevent unnecessary situations like catching a cold due to significant temperature differences between the inside and outside of the car. 3. Disinfecting wipes: After drivers or passengers return to the car from public places, it is recommended to first use hand sanitizer for hand hygiene. If relatives or friends (with unknown health status) have been in the car, promptly open the windows for ventilation and disinfect the surfaces of relevant objects inside the car. You can choose legally effective disinfectants or disinfecting wipes for wiping and disinfection.

What are the rules for entering a service road from the main road?

Rules for entering a service road from the main road: 1. Use turn signals: When driving on the main road, if approaching a traffic light intersection, you must enter the service road before making a right turn. When merging from the main road into the service road, use your turn signals to inform vehicles behind you that your vehicle intends to change lanes. 2. Observe the situation: Before entering the service road, observe the conditions on the service road to ensure there are no vehicles behind you. Merge slowly, as there may be blind spots in the rearview mirror. If necessary, stop between the main road and the service road to clearly assess the situation before merging to avoid any unexpected incidents. 3. Steer gently: When merging into the service road, avoid turning the steering wheel too sharply. This gives vehicles behind you in the service road time to react. Observe the movement of vehicles going straight on the service road before entering. 4. Follow the correct route: On roads with service lanes, it is often necessary to enter the service lane when making a right turn from the main road. Therefore, while driving, follow the road markings, signs, and indicators to choose the correct lane.

Will the Subject 2 Test Be Cancelled in Heavy Rain?

It depends on the intensity of the rain. Generally, light rain will not affect the test, and only extremely severe weather or torrential downpours will lead to cancellation. Don't panic if you take the test on a rainy day—maintaining composure is most important. Slowing down your speed will give you more time to think and react, and by using the methods taught by your instructor, you can still pass the test with ease. Here are some relevant details: 1. Disadvantages of taking the test on a rainy day: Although rain can make boundary lines and reference points clearer after being washed by the rain, excessive water accumulation can obstruct visibility. Additionally, rainwater on the rearview mirrors and windshield, as well as fogging inside the car, can impair your view. 2. Preparations for a rainy-day test: Wipe the rearview mirrors clean before getting in the car; avoid closing the windows too tightly, as this can cause fogging on the windshield; promptly turn on the wipers and adjust their speed according to the rain intensity to ensure clear visibility; wear anti-slip shoes, as wet soles may cause slipping when pressing the pedals, or dry your soles with a cloth before stepping on the pedals.

What are the solutions when the engine malfunction indicator light is on?

When the engine malfunction indicator light is on, you can follow these steps to address the issue: First, check if the engine is running normally and whether there are issues such as shaking or emitting black smoke. If any of these problems exist, avoid restarting the engine. Particularly, if the light is red, do not attempt to start the engine under any circumstances. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once or turn the car key halfway to the 'on' position without depressing the clutch. The car will initiate a self-check function upon powering up. Wait for 5-10 seconds and observe whether the malfunction indicator light on the dashboard turns off. If the light remains on, visit a service station as soon as possible to diagnose the issue. The service station can use a portable diagnostic tool to read the fault codes, obtain fault information, and perform targeted repairs. There are primarily seven reasons why the engine malfunction indicator light may illuminate: Sensor failure: This includes sensors such as the coolant temperature sensor, crankshaft position sensor, air flow sensor, intake air temperature sensor, and oxygen sensor. If these sensors are damaged, have poor contact, or their signals are interrupted, the car's ECU cannot accurately obtain engine data, leading to the illumination of the engine malfunction light. Fuel quality issues: Failure to use the fuel and oil as specified by the manufacturer may cause engine wear, resulting in the malfunction light turning on. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon deposits or knocking. When detected by the oxygen sensor and reported to the ECU, the malfunction light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can cause poor combustion of the air-fuel mixture. Turbocharger issues: Problems with the intake boost pipes or turbocharger can also trigger the engine malfunction light. The most common issue is a damaged turbocharger, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake problems: If the car's intake system is compromised, it may lead to clogged engine pipes, and in severe cases, the engine malfunction light will illuminate. A dirty air filter that is not cleaned regularly can cause intake issues. Exhaust problems: Exhaust system faults can also cause the engine malfunction light to turn on. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings. The catalytic converter is the most frequent culprit, especially when using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the converter, or faults in the engine's fuel supply system. Anti-theft system malfunction: If the car's electronic anti-theft system malfunctions or if there is a mismatch between the anti-theft controller and the engine's electronic control unit, the anti-theft system can prevent the engine from operating normally and trigger the engine malfunction light.
