What are the requirements for scheduling Subject 1?

To schedule Subject 1, you must complete the required study hours. Subject 1 requires 12 study hours, with a maximum of 4 hours per day, meaning it can be completed in as little as 3 days. You can schedule the Subject 1 exam either through the driving school where you registered or independently via the mobile app "Traffic Management 12123." Scheduling steps: Open the "Traffic Management 12123" mobile app and enter the homepage; After entering the main interface, click "More" to access the service center; Find and click on "Driver's License Services"; Within the "Driver's License Services" interface, locate and enter "Exam Scheduling"; Follow the app's guidance step by step to complete the exam scheduling process. Subject 1 exam scheduling rules: For first-time scheduling of Subject 1, the scheduling order is based on the initial application date for the driver's license or upgrade application. For non-first-time scheduling, the order is based on the date of the last exam. If a user cancels a successfully scheduled exam due to personal reasons, the cancellation date becomes the new scheduling order date. If the exam cannot be taken for reasons beyond the user's control, the scheduling order date remains unchanged.

What is the reason for not receiving a text message after successfully scheduling the Subject 4 exam?

Take the appointment result as the main reference, as there might be cases where the text message was not successfully received. Introduction to Subject 4: Subject 4, also known as the Subject 4 theoretical exam or driver theory test, is part of the motor vehicle driver's license assessment. After the implementation of the "Order No. 139 of the Ministry of Public Security of the People's Republic of China," the Subject 3 exam was divided into two parts: besides the road test, a safety and civilization knowledge test was added, commonly referred to as "Subject 4," which evaluates "driving ethics." Since this exam is conducted after Subject 3, it is habitually called the Subject 4 exam. It mainly includes safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-traffic accident handling knowledge. The exam process is as follows: First, to take the Subject 4 exam, one must pass the Subject 3 exam. After receiving the Subject 4 exam card, wait in line for the exam. During the exam, hand the card to the examination staff, who will arrange the exam machine for the candidate. On the exam machine, input the candidate's ID number and press the fingerprint to begin the exam.

Can a Naturally Aspirated Engine Modified to Turbo Pass the Annual Inspection?

Modifying a naturally aspirirated engine to turbo will not pass the annual inspection as it constitutes illegal modification. Relevant legal provisions: No unit or individual may assemble a motor vehicle or alter the registered structure, construction, or characteristics of a motor vehicle without authorization. Without permission from the public security traffic management department, any unauthorized modification to the motor vehicle's chassis, engine, suspension, transmission system, steering system, tire rims, lights, body color painting and exterior structure, as well as any technical data of the motor vehicle that does not match the data announced by the competent department of motor vehicle products under the State Council, are considered modification acts. Precautions for modification: For the powertrain, only the original factory engine can be replaced, and an application for change registration must be submitted to the vehicle management office within 10 days after the replacement; the spraying or pasting of logos or body advertisements on motor vehicles must not affect safe driving; the body cannot have more than three main colors, and the use of fire engine-specific red, engineering vehicle-specific orange, police vehicle-specific blue and white, or special vehicle-specific camouflage colors is prohibited.

What are the differences between racing cars and ordinary cars?

Here are the main differences between racing cars and ordinary cars: 1. Tires: For common racing cars, the tires perform best when the temperature is around 100°C, providing maximum grip on the ground. Before participating in a race, the tires are preheated in a heater and then installed on the car. Only after completing a full lap do the tires reach their optimal state. Ordinary cars do not require this. 2. Seat belts: The seat belts in civilian cars are generally diagonal three-point type and come with a pre-tensioning device. Under normal driving conditions, they can be easily pulled to the driver's chest and abdomen to avoid discomfort. They only automatically tighten during emergency braking or severe body shaking to secure the occupant in the seat and prevent impact with the windshield. Racing cars have higher requirements; their seat belts are double-shoulder fixed with an additional strap across the waist and lack a pre-tensioning device. Racing seat belts also feature a quick-release mechanism. In case of an accident, pressing the square button on the chest will instantly release all the various straps wrapped around the body, allowing the driver to escape quickly. 3. Engine and fuel: Racing car engines require high RPM and power output. Therefore, these engines have very short piston strokes, large displacement, and small mass, which helps increase the engine's RPM and power. In contrast, ordinary car engines rarely operate at extremely high RPMs.

Should the Tiguan use 95 or 92 octane gasoline?

According to the official vehicle manual recommendation, the Tiguan should use 95 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, the Tiguan's fuel cap also displays this information. Typically, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of new technologies, the compression ratio alone cannot determine the gasoline grade, as high compression ratios can also be adjusted to use lower-grade gasoline. Factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also influence this decision. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Tiguan occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. However, prolonged use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower-grade gasoline, using higher-grade gasoline will not cause damage, but the increased octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles recommended to use higher-grade gasoline, using lower-grade gasoline can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will develop during the upward stroke. This resistance makes the engine run very unstably. Mild knocking may only increase noise without obvious engine damage, but noticeable knocking indicates severe engine conditions. The vibrations not only affect driving stability but also cause abnormal wear on pistons and cylinders, potentially leading to cylinder scoring in severe cases.
