Does the Engine Need Carbon Deposit Cleaning?

Engine carbon deposit cleaning is necessary. The faults caused by engine carbon deposits: 1. Combustion chamber carbon deposits: Can lead to engine knocking; 2. Fuel injector carbon deposits: May cause engine shaking and poor acceleration; 3. Throttle body carbon deposits: Can result in weak vehicle acceleration and unstable idle speed, making it difficult to start. Methods for cleaning engine carbon deposits: 1. Install a three-way catalytic converter in the vehicle's exhaust system at the bottom, primarily to reduce exhaust pollutants emitted by the engine; 2. Pour a bottle of engine internal cleaner into the engine oil, then idle the engine for 30 minutes to clean before draining the old oil, replacing the oil filter and adding new engine oil; 3. Remove the engine cover, take off the throttle body, use a cleaner to remove carbon deposits and other stains inside the throttle body and on the flap valve, then dry with a cotton cloth.

Can You Wear Slippers for the Subject 1 Test?

There are no explicit regulations, but please avoid wearing clothing such as tank tops, vests, slippers, etc., otherwise entry to the examination hall will be prohibited. If wearing hats, masks, scarves, or other facial coverings, you may enter the examination hall after removing them. Notes for the Subject 1 test: Candidates should pay attention to their attire during the Subject 1 test; slippers are not allowed, and electronic devices and bags are prohibited from being brought into the examination hall. Bring your ID card and queue to enter the waiting hall. Observe the notes and procedures on the large screen, and place personal belongings in the lockers before entering the examination hall. Upon entering the examination hall, seats are assigned at the identity verification point. After finding your seat, begin the test. Ensure the camera is aligned with you and adhere to examination discipline. If you fail the first time, there is a same-day retest. If you fail again, you must pay to reschedule. After completion, queue to collect your score report and sign it. Without a signature, the result is invalid. The "Regulations on the Application and Use of Motor Vehicle Driving Licenses" clearly stipulate that the Subject 1 test can be taken twice on the same day. If you fail the first time, you can retake it for free the second time. If you fail the second time, the Subject 1 test is terminated, and you can only reschedule after ten days. Subject 1, also known as the theoretical test or driver's theory test, is part of the motor vehicle driving license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The Subject 1 test consists of 100 questions, divided into single-choice and true/false questions, with each question worth 1 point and a total score of 100 points. If you answer 11 questions incorrectly during the test, the system will automatically submit the test and end it. The Subject 1 test is computer-based. The test time is limited to 45 minutes. Subject 1 test content: Driving license and motor vehicle management regulations; Road traffic conditions and regulations; Road traffic safety violations and penalties; Road traffic accident handling regulations; Basic knowledge of motor vehicles; Local regulations; Knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; Specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. There is no limit to the number of times you can reschedule the Subject 1 test. Each subject can be taken once, and if you fail, you can retake it once. If you do not attend the retest or fail the retest, the test is terminated, and the applicant must reschedule. For Subject 2 and Subject 3, there are only five test attempts. Subject 2 and Subject 3 tests must be rescheduled after ten days. If you fail the Subject 3 safe and civilized driving knowledge test, the previously passed road driving skills test results remain valid. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge test; Subject 2 refers to the field driving skills test; Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge test. The safe and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, in official terms (i.e., the Ministry of Public Security Order No. 123), there is no such thing as Subject 4.

What Causes Abnormal Tire Pressure on the Dashboard?

Abnormal tire pressure on the dashboard is caused by either overinflation or underinflation, requiring you to stop and check the tire pressure. Indirect tire pressure monitoring systems determine tire pressure by comparing the rotational speeds of the four wheels. However, this method has some limitations—it cannot specifically indicate which tire has insufficient pressure and may produce false alarms under certain conditions. Therefore, any factor that causes inconsistent wheel speeds can trigger a tire pressure warning. For example, after replacing a single tire, the new tire may have a slightly different diameter from the old ones, causing the new wheel to rotate at a different speed. If the speed difference reaches a certain threshold, the tire pressure monitoring system will illuminate the warning light. Similarly, when driving on sand or icy roads, if a wheel slips and spins excessively, the system may interpret this as abnormal tire pressure and trigger an alarm.

Can a Car Charge Without Starting the Engine?

Can a Car Charge Without Starting the Engine? A car can charge without starting the engine. The car battery can be charged through the rotation of the engine. As the engine runs, the alternator is driven by the belt to generate electric current. The current passes through the vehicle's voltage regulator transformer, with part of the filtered current used for driving the vehicle, and the excess portion used to charge the car battery. Precautions for in-car charging: 1. The USB port in the car is designed for audio data transmission, and most vehicle ports only provide 5V current, which may damage the charging device if it does not meet the required standards; 2. The output current from the car charger should not exceed the maximum rated input power of the phone; 3. Always unplug the car charger after turning off the engine, as leaving it plugged in can damage the battery.

Which gear should be used when driving uphill?

When driving uphill, the car should be in third gear. If there are passengers, it can be appropriately adjusted to second gear. In cases of steep slopes or heavy loads, first gear can be used. Steps to restart the car if it stalls during an uphill climb: 1. Engage the handbrake firmly to prevent the car from sliding due to inertia; 2. Press the clutch pedal and shift into first gear; 3. Gently release the clutch until the tachometer shows a noticeable drop and the car starts to shake; 4. After lightly releasing the clutch, when the RPM is low, press the accelerator to reach 1500 RPM; 5. Release the handbrake; 6. Feel the car moving forward slowly—at this point, keep the clutch steady and increase the throttle to prevent the car from rolling back or stalling.
