What is an EGR Valve?

EGR valve is an exhaust gas recirculation system, an exhaust purification device designed for nitrogen oxides (NOx), one of the harmful gases in engine emissions. Below is an introduction to the EGR system: 1. Function: The main component of the EGR system is the digital control EGR valve, which is installed on the right exhaust manifold. Its role is to independently and accurately control the amount of exhaust gas recirculated back to the engine, regardless of the manifold vacuum level. 2. Working Principle: The EGR valve controls the amount of exhaust gas flowing back from the exhaust manifold to the intake manifold through three metering holes of increasing diameters, creating various flow combinations. Each metering hole consists of a solenoid valve and a needle valve. When the solenoid valve is energized, the armature is magnetically pulled upward, opening the metering hole and the valve. The rotary needle valve ensures excellent sealing when the EGR valve is closed.

What are the sighting techniques for driving on an S-curve?

Sighting techniques for driving on an S-curve are as follows: When the front part of the vehicle touches the right boundary line, you need to quickly steer to the left by half a turn, and vice versa for the opposite direction. During the test, if the front of the vehicle is about to go out of the boundary line, steer more to the left to allow the vehicle to pass through the S-curve normally. Relevant information is introduced as follows: The S-curve driving is a mandatory test item in the subject two of the motor vehicle driver's license examination. If you are not well-practiced in this item, you can practice several times until you master it before registering for the test. This will increase the chance of passing the test on the first attempt. If you fail on the day of the test, you can retake it once after other students have finished their tests. If you fail again, you will need to go back and continue practicing.

What Happens If You Don't Surrender Your Old Driver's License When Adding a Driving Category?

Continuing to use the old driver's license without surrendering it when adding a driving category will result in a fine. Procedures after passing the additional driving test: After passing the additional driving test, the old license must be surrendered, and a new one will be issued. If the old license is not surrendered, it cannot be used anymore. Continued use is illegal and will incur a fine. Important notes after passing the additional driving test: You cannot drive between the time the old license is surrendered and the new one is issued. Relevant laws and regulations: According to Article 19 of the 'Regulations on the Application and Use of Motor Vehicle Driver's Licenses,' when applying to add a driving category, in addition to filling out the 'Motor Vehicle Driver's License Application Form' and submitting the proofs specified in Article 18, the current motor vehicle driver's license must also be submitted.

How often should RAV4 tires be replaced?

RAV4 tires generally last 3-5 years, with a recommended maximum mileage of 60,000 kilometers. The lifespan of car tires is directly related to the driver's habits and driving conditions. Regular assessment of tire condition is necessary during daily use, and immediate replacement is required when tires become unsafe. Below are indicators for tire replacement: 1. Sidewall bulges: If bulges appear on the tire sidewalls, replace them immediately as these are difficult to repair. Bulges indicate broken cords inside the tire, which may lead to sudden blowouts during driving. 2. Tire cracks: Cracks of varying lengths and depths commonly appear during normal use. If unsure about tire condition, visit a 4S store or professional auto repair shop for inspection. Severe cracking may lead to bulges and potential blowouts. 3. Wear indicators: Tires feature wear markers showing the maximum allowable wear limit. When tread reaches these markers, replace tires immediately as they pose significant safety risks - even on dry roads, braking distance increases substantially, while wet roads may cause skidding or brake failure.

How to Distinguish the Front and Back Sides of a Car Air Conditioning Filter?

Distinguishing the front and back sides of a car air conditioning filter can be done as follows: 1. Determine by the arrow direction on the car air conditioning filter: The arrow direction on the car air conditioning filter actually indicates the front and back sides of the filter. The direction the arrow points represents the airflow direction, which is also the installation direction. If the arrow points upward, that is the front side, which should face the airflow direction during installation. 2. Judge the front and back sides by observing the surface of the air filter: The ordinary fuzzy side is the front side, facing upward towards the airflow direction, while the side with a support line structure is the back side, facing away from the airflow direction. For filters containing activated carbon, the black side facing the airflow direction is the front side, and the white side facing away from the airflow direction is the back side.

Can a Dash Cam Record When the Car is Not Running?

A dash cam cannot record when the car is not running. Here are the detailed features of a dash cam: 1. Time Options: The loop recording settings of a dash cam typically include options such as 1 minute, 2 minutes, 3 minutes, 5 minutes, and 10 minutes. Once a segment is recorded, it moves on to the next. 2. Optimal Loop Time: When setting the loop recording time, it's advisable not to set it too short or too long. If the recording time is too short, the video will be split into more segments, increasing the chance of losing frames. Conversely, if the time is too long, fewer videos will be stored, and they will be overwritten quickly. It is recommended to set the loop time to 3 or 5 minutes for optimal performance. 3. Function: A dash cam is a device that records images, sounds, and other relevant information during vehicle operation. Once installed, it can record the entire driving process in video and audio, providing evidence in case of traffic accidents.
