The reasons why an ignition coil burns out are: 1. Excessive power generation, causing the ignition coil to be overloaded; 2. Excessive spark plug gap; 3. Poor fuel quality; 4. Incorrect cylinder compression ratio; 5. Program failure in the computer board; 6. Unstable power supply voltage; 7. Abnormal resistance in the high-voltage wires; 8. Secondary circuit short; 9. Excessive primary current from the ignition controller leading to overheating of the ignition coil. The steps to replace the ignition coil are: 1. Open the ignition coil cover on top of the engine; 2. Remove the ignition coil fixing screws; 3. Disconnect the ignition coil power plug; 4. Take out the ignition coil; 5. Insert the new ignition coil and tighten the screws; 6. After connecting the power plug, cover the top panel.

What are the differences between Toyota hybrid and Honda hybrid?

The main differences between Toyota hybrid and Honda hybrid are: 1. The primary distinction between Honda and Toyota hybrid systems lies in their driving logic. Toyota's hybrid system operates on a THS system, primarily driven by a gas turbine and electric motor, then distributing power through planetary gears to match the motor and engine power. 2. Honda's hybrid system utilizes electric drive technology, which minimizes intermediate conversion processes during operation to maximize power output. Compared to Toyota's hybrid model, Honda's hybrid vehicles offer stronger power performance while being more fuel-efficient. 3. The issue with Toyota hybrids is that the Atkinson cycle engine's output is weaker than conventional engines, and the hybrid model's output capacity and capacitance cannot simultaneously support maximum power output from both engines. Therefore, the engine must not only provide power but also compensate for the electric motor's relatively weaker output.

Will Volkswagen cars automatically lock themselves?

Volkswagen cars do not automatically lock themselves. Introduction to automatic locking: Automatic locking occurs when the owner unlocks the car with the remote key and no one touches any door, including the trunk, within 1 minute. The doors will relock within that minute. However, if the owner gets out of the car and closes the door but forgets to lock it, the vehicle will not automatically lock itself. What if the owner's keys are left inside the car? Therefore, it is necessary to press the remote to lock the car. Purpose of automatic locking: The automatic locking function is designed for theft prevention. It allows the doors to lock quickly after driving, preventing door-pull robberies during traffic jams or at red lights, providing a certain level of security.

What are the questions for the driving license test subject one?

The driving license test subject one consists of 100 questions, according to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," divided into single-choice questions and true/false questions, with each question worth 1 point, totaling 100 points. If 11 questions are answered incorrectly during the test, the system will automatically submit the paper and end the test. Subject one, 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 other related knowledge. The test is conducted on a computer, with a limited time of 45 minutes. Subject one 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. Subject one test precautions: During the subject one test, students should pay attention to their attire—no slippers are allowed, and electronic devices and bags are prohibited in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in a locker before entering the examination room. Upon entering the examination room, the identity verification station will assign a seat. After finding your seat, begin the test. Ensure the camera is aligned with you and follow the test discipline. If you fail the first time, there is a retake opportunity on the same day. If you fail again, you must pay to reschedule. After the test, queue to collect your score sheet and sign it—failure to sign will render it invalid. There is no limit to the number of times you can schedule the subject one test. Each subject can be taken once, and if you fail, you can retake it once. If you do not take the retest or fail the retest, the current test session will be terminated, and the applicant must reschedule the test. Subjects two and three, however, have only five test attempts each. Subjects two and three can be rescheduled after ten days. If you fail the subject three safe and civilized driving knowledge test, the previously passed road driving skills test scores remain valid. The driving test consists of three subjects: subject one, subject two, and subject three. Subject one refers to the road traffic safety laws, regulations, and related knowledge test; subject two refers to the field driving skills test; subject three 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 three, so it is commonly referred to as subject four. However, in official terms (i.e., the Ministry of Public Security Order No. 123), there is no such thing as subject four.
