How Many Times Can You Retake the Driving Test?

There is no limit on retaking the theoretical tests (Subjects 1 and 4) for the driving license; for the practical tests (Subjects 2 and 3), you can schedule the test up to five times, totaling ten attempts. Below are the detailed rules regarding the number of retakes for each subject: 1. Subject 1: There is no limit on retakes. You will have one immediate retake opportunity during the test session, and each scheduled test allows two attempts. 2. Subject 2: You can schedule the test up to five times, with two attempts allowed per scheduled test, totaling ten attempts. 3. Subject 3: Similar to Subject 2, you can schedule the test up to five times, totaling ten attempts. 4. Subject 4: There is no limit on retakes. You will have one immediate retake opportunity during the test session, and each scheduled test allows two attempts.

What are the body dimensions of the Sagitar?

The length, width, and height of the Sagitar are 4753mm/1800mm/1462mm, which are official data. The length of the Sagitar refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding points at the front and rear of the vehicle. The width refers to the distance between two parallel planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding points on both sides of the vehicle. The height refers to the distance between the highest point of the vehicle and the supporting plane. The Sagitar's turbocharged engine delivers a maximum power of 110kW and a maximum torque of 250Nm. This engine achieves its maximum power at 5000-6000 rpm and its maximum torque at 1750-3000 rpm. It features direct fuel injection technology and uses an aluminum alloy cylinder head and block. This engine is paired with a dry dual-clutch transmission (DCT). National regulations stipulate specific requirements for vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle excludes side mirrors. The limitation on vehicle width is intended to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that, under national standards, the significance of vehicle width data lies in ensuring adequate space during overtaking, preventing accidents or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to comply with public road usage requirements.

What Causes Fuel Injector Failure?

Fuel injector failure can be caused by the following reasons: 1. Poor fuel atomization: When the injection pressure is too low, the injector nozzle is worn or has carbon deposits, or the spring end face is worn or the spring force is reduced, the injector will open prematurely and close late, resulting in poor fuel atomization. 2. Damaged injector return line: When the needle valve pair is severely worn or the fit between the needle valve body and the injector housing is not tight enough, the injector's return fuel volume increases significantly, sometimes reaching 0.1–0.3 kg/h. If the return line is damaged or missing, the return fuel is wasted. 3. Enlarged needle valve nozzle: Due to continuous high-pressure fuel flow erosion, the needle valve nozzle gradually wears out, leading to decreased injection pressure, shorter injection distance, poor diesel atomization, and increased carbon deposits in the cylinder. 4. Needle valve seizure: Water or acidic substances in the diesel can cause the needle valve to rust and stick. If the needle valve sealing cone surface is damaged, combustible gas in the cylinder can also enter the mating surface, forming carbon deposits that cause the needle valve to seize, rendering the injector non-functional and stopping the cylinder. 5. Wear on the needle valve body end face: The needle valve body end face is subjected to frequent reciprocating impacts from the needle valve, which over time forms a concave pit, increasing the needle valve lift and affecting the injector's normal operation. 6. Air leakage and oil seepage at the injector and cylinder head joint: When installing the injector into the cylinder head, carefully remove carbon deposits from the installation hole. The copper gasket must be flat and should not be replaced with asbestos or other materials to prevent poor heat dissipation or sealing failure. 7. Wear on the needle valve and needle valve bore guide surface: The needle valve's frequent reciprocating motion inside the needle valve bore, combined with contamination from diesel impurities, gradually wears the guide surface, increasing the gap or causing scratches. This leads to increased internal leakage in the injector, reduced pressure, decreased fuel injection volume, delayed injection timing, and difficulty starting the diesel engine. 8. Injector dripping: During injector operation, the needle valve body's sealing cone surface is subjected to frequent strong impacts from the needle valve, along with continuous high-pressure fuel flow erosion. Over time, the cone surface develops scratches or spots, losing its sealing ability and causing the injector to drip fuel.

What to Do When Car Windshield Washer Fluid Freezes?

Manually clean the windshield, then start the vehicle and use the heat generated by the vehicle's operation to melt the washer fluid. Here is some relevant information about washer fluid: 1. Types of washer fluid: There are many types of washer fluid available in the domestic market, but they can mainly be divided into three categories: summer washer fluid, winter antifreeze washer fluid, and special antifreeze washer fluid. Summer washer fluid is primarily used to remove insect residue from the windshield. It is important to choose the appropriate washer fluid based on different climates and temperature conditions. 2. Functions of washer fluid: High-quality washer fluid features rapid snow and ice melting, anti-glare, and anti-fogging properties, which play a significant role in improving driving safety.

What to Do When the Car Fogs Up on Rainy Days?

Here are solutions to remove fog inside the car on rainy days: 1. Turn on the air conditioning cold air: Direct the air vents towards the windows, set the fan to maximum speed and the temperature to low to eliminate fog inside the car. 2. Open the windows at diagonal positions inside the car: This helps in removing fog. 3. Use anti-fog spray: Prevents water vapor from condensing into fog on the glass, one application can prevent fog for about ten days. Below are precautions for driving on rainy days: 1. Maintain a sufficient safe distance. 2. Use lights correctly. 3. Avoid slamming the brakes, stepping on the accelerator too hard, or turning the steering wheel abruptly.

Should CRV Use 92 or 95 Octane Gasoline?

Honda CRV uses 92 octane gasoline. Below is relevant information: 1. Gasoline Quality: Gasoline is produced and sold by octane rating, which is specified by national gasoline product standards and relates to different standards. For China (V), the ratings are 89, 92, 95 (with 98 included in the appendix). Gasoline grades are classified by octane number. 2. Reducing Fuel Consumption: The most cost-effective method to reduce fuel consumption is to increase the engine's compression ratio. Increasing the compression ratio involves altering the piston stroke—the more the air-fuel mixture is compressed, the greater the combustion reaction and the more complete the combustion.
