The AC button in a car represents the air conditioning cooling switch. Pressing the AC button activates the air conditioning compressor, causing cold air to blow out. The car air conditioning system is a device designed to cool, heat, ventilate, and purify the air inside the vehicle. Passenger cars commonly use an integrated heating and cooling air conditioning system, where components such as the evaporator, heater radiator, centrifugal blower, and control mechanism are assembled together, known as the air conditioning unit assembly. The car air conditioning system is used to adjust and control the temperature, humidity, air cleanliness, and airflow inside the vehicle to optimal conditions, providing a comfortable riding environment for passengers, reducing travel fatigue, creating favorable working conditions for the driver, and serving as a crucial ventilation device for ensuring safe driving.

Can I Check My Results After Passing Subject 4?

You can check your results after passing Subject 4. Here are the relevant details: 1. Subject 4: Also known as the Subject 4 theory test or driver theory test, it is part of the motor vehicle driver's license examination. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 test was divided into two parts: the road test and an additional safety and common sense knowledge test. 2. Important Notes: If you fail Subject 4, you do not need to retake the previously passed subjects (Subject 1, Subject 2, Subject 3). You can schedule a retest on your own. Currently, there are no restrictions on scheduling the safety and civilized driving theory test. However, the driving skills permit is valid for three years. If the applicant does not complete the test within the validity period, the results of the previously passed subjects will be invalidated.

Does the CR-V have a particulate filter?

The Honda CR-V is equipped with a particulate filter to meet the China VI emission standards. The particulate filter is a ceramic filter installed in the diesel engine's emission system, which captures particulate emissions before they enter the atmosphere. It can reduce the soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Diesel engine pollution mainly comes from three sources—particulate emissions, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Among these, particulate emissions (soot) are mostly composed of tiny particles of carbon or carbon compounds (smaller than 4-20μm). How the particulate filter works: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the engine's exhaust particulate filter through a dedicated pipe. After passing through its densely arranged bag-type filter, the carbon soot particles are adsorbed onto a filter made of metal fiber felt. When the adsorption of particles reaches a certain level, the burner at the end automatically ignites, burning off the adsorbed carbon soot particles and converting them into harmless carbon dioxide. To check whether the CR-V has a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, you can carefully review the fault codes in the manual to see if there is a "Particulate Filter" warning light indicator. Check the label on the oil filler cap. If the oil filler cap clearly indicates 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Look behind the three-way catalytic converter to see if there is a cylindrical section on the exhaust pipe. If there is, that is the particulate filter.
