Where to Book the Subject 4 Exam?

Subject 4 can be booked on the local DMV website. Below are the specific reasons for failing to book the exam: 1. Low priority: Too many people are booking at the same time, and your priority is lower than others. There is no need to rush to log in and book, as slots are allocated based on priority. Even if you book early, you may not succeed if your priority is lower than others. For the first booking of Subject 1, the sorting time is based on the date when the user initially applied for a driver's license. For non-first bookings of any subject exam, the sorting time is based on the date of the last exam taken. 2. System issues: Sometimes, the system is under too much pressure, leading to some students being unable to book. In such cases, you can only wait for the system to be fixed.

What is the general torque for tires?

Different brands and models of vehicles have varying specifications for wheel bolt tightening torque. Therefore, it is essential to refer to the vehicle's maintenance manual or owner's manual, adhering strictly to the manufacturer's guidelines as the sole standard. Car tire maintenance methods: 1. Ensure proper inflation pressure: In winter, when temperatures are lower, drivers should slightly increase tire inflation pressure to reduce wear and tear. It is recommended to use 10% to 15% higher than the standard inflation pressure. If the tire pressure is insufficient, it should be promptly replenished. 2. Control driving speed: When starting after parking in cold conditions, it is necessary to drive at a lower speed initially. 3. Enhance protection and cleanliness: During cold seasons, pay attention to tire cleaning before and after driving. Before driving, check the tread grooves for debris such as broken glass, ice, or nails. 4. Monitor wear indicators: New and old tires differ in traction and grip, especially severely worn tires, which may not be suitable for winter driving. If tires show significant wear, they should be replaced promptly.

What is the function of the exhaust stroke?

The function of the exhaust stroke is to expel exhaust gases. Below is a detailed introduction to four-stroke engines: 1. Classification: Four-stroke engines belong to reciprocating piston internal combustion engines. Based on the type of fuel used, they are divided into three categories: gasoline engines, diesel engines, and gas fuel engines. Piston internal combustion engines that use gasoline or diesel as fuel are called gasoline engines or diesel engines, respectively. Piston internal combustion engines that use natural gas, liquefied petroleum gas, and other gaseous fuels are called gas fuel engines. Both gasoline and diesel are petroleum products and are traditional fuels for automotive engines. Non-petroleum fuels are called alternative fuels. Engines that use alternative fuels are called alternative fuel engines, such as ethanol engines, hydrogen engines, methanol engines, etc. 2. Working process: A four-stroke gasoline engine completes one working cycle through four strokes: intake, compression, power, and exhaust. During this process, the piston moves up and down four times, and the corresponding crankshaft rotates two revolutions.

What kind of car generally has a speedometer that goes up to 240 mph?

240 mph refers to a car whose speedometer has a maximum scale of 240 kilometers per hour. Here is some additional information: 1. Car odometer: The car odometer indicates the speed of the car, measured in km/h (kilometers per hour). It consists of two meters: one is the speedometer, and the other is the odometer. It is usually located directly in front of the driver's position. Identification methods include determining the wear level or checking the car's maintenance records at a 4S shop. 2. Car speedometer: The maximum scale on the car speedometer is called the "speedometer bottom." Generally, the maximum speed indicated on the car speedometer is based on the highest possible speed value under the engine's no-load maximum RPM. Therefore, the higher the speedometer bottom value, the better the performance of the car.

What are the penalty points for reverse parking?

Penalty points for reverse parking: Not following the prescribed route or sequence, deduct 100 points; Vehicle body crossing the line, deduct 100 points; Failing to park in the designated area, deduct 100 points; Stopping midway, deduct 100 points. Here is additional information: 1. Reverse parking: Reverse parking is a mandatory test item for obtaining a small car driver's license after 2013. It assesses the driver's ability to operate the vehicle in a confined space. Reverse parking is a key assessment point in the driver's test, which involves maneuvering the vehicle correctly into the garage from both sides while in motion. 2. Tips: Control the driving speed. Use first gear or reverse gear at idle speed throughout the process, maintaining the same speed as when starting.

How to Solve the Dashboard Engine Warning Light?

Solution for the dashboard engine warning light: When the engine warning light comes on, you should not continue driving. It is necessary to promptly visit a 4S shop or repair shop for inspection. During the inspection, a professional technician should use a specialized diagnostic computer to read the fault codes. After the engine warning light comes on, fault codes will be generated in the computer, which can be read using a professional diagnostic computer. The probability of the car's engine itself malfunctioning is relatively low, while the probability of faults occurring in the electronic systems and control mechanisms around the engine is relatively high. There are many sensors and control mechanisms around the car's engine. During regular maintenance, you can also have professionals use a diagnostic computer to read the fault codes, so that any issues with the car can be promptly identified.
