What are the key knowledge points for Subject 4 exam?

Subject 4 knowledge points: 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-accident handling knowledge. Below is a detailed introduction to Subject 4: 1. Overview: Subject 4, also known as the Subject 4 theoretical test or driver's theory test, is part of the motor vehicle driver's license assessment. Currently, the Subject 3 exam is divided into two parts: besides the road test, a safety and civilization knowledge test has been added, commonly known as "Subject 4", which assesses "driving ethics". 2. Retake instructions for Subject 4: If you fail Subject 4, you do not need to retake the previously passed items (Subject 1, Subject 2, Subject 3). You can schedule a retake on your own, and no retake fee is required.

How to Calculate Exhaust Emissions?

Actual exhaust emissions = Emission rate x Production days x Daily working hours x 10-3 or Actual exhaust emissions = Emission concentration x Benchmark flow rate x Production days x Daily working hours x 10-9. Below is relevant information about vehicle exhaust emissions: 1. Meaning of vehicle emission standards: Vehicle emission standards refer to harmful gases emitted from vehicle exhaust such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), PM (particulate matter, soot). In China, commonly used terms like Euro I and Euro II standards refer to emission directives issued by the EEC in those respective years. 2. Hazards of vehicle exhaust: When there are few vehicles, the atmosphere's self-purification capacity can still neutralize toxins emitted by vehicles. However, with the dramatic increase in vehicle numbers and traffic congestion becoming commonplace, excessive vehicle exhaust has become significantly harmful, seriously affecting human health.

What is the standard thickness of automotive paint?

The standard thickness of automotive paint ranges between 120 to 180 micrometers. The functions of automotive paint include: 1. Protecting the car from erosion by various corrosive agents in the atmosphere. 2. Decorating the car. 3. Identifying the type of car. 4. Enhancing the comfort and sealing of the car, preventing noise caused by vibrations. The main paint processes are: 1. Electrophoretic paint: Its role is to prevent rust and corrosion. 2. Primer paint: Its role is to resist ultraviolet rays and stone impacts, laying the foundation for the color paint. 3. Color paint layer: Its role is to enhance aesthetics. 4. Clear coat layer: Its role is to give the car body a glossy appearance and resistance to friction.

How to Remove a Pebble Stuck in the Brake Disc?

The methods to deal with a pebble stuck in the brake disc are as follows: accelerate the car and then slam on the brakes, then reverse and slam on the brakes again. Repeat this cycle several times to resolve the issue. If this doesn't work or if you're concerned about the car, it's recommended to visit a repair shop or a 4S store. The automotive braking system consists of the following components: 1. Brake operating mechanism: This includes parts that generate braking action, control braking effects, and transmit braking energy to the brakes, such as brake wheel cylinders and brake lines. 2. Brake: The component that generates a force (braking force) to resist the movement or tendency of movement of the vehicle. The brakes commonly used in automobiles generate braking torque through friction between fixed elements and the working surfaces of rotating elements, known as friction brakes. There are two structural types: drum brakes and disc brakes.

How to Perform Wheel Balancing?

Tire dynamic balancing operation steps are as follows: 1. Remove the tire from the vehicle and secure it on the balancing machine. 2. Input the required values as prompted by the balancing machine. 3. Rotate the tire to read the dynamic imbalance value. 4. Add counterweight balance blocks for correction. 5. Reinstall the balanced tire onto the vehicle to complete the balancing process. Wheel balancing should be performed under the following circumstances: 1. After installing new tires or post-collision repair. 2. When experiencing unilateral wear on front/rear tires. 3. When the steering wheel feels excessively heavy or vibrates during driving. 4. When the vehicle pulls to the left or right during straight-line driving. 5. For maintenance purposes, it's recommended to perform balancing every 6 months or 10,000 km after the first 9 months of new vehicle ownership, even without the above symptoms.

Does Using the Heater in Winter Increase Fuel Consumption in Cars?

Yes, using the heater in winter does increase fuel consumption to some extent. During cold weather, the engine temperature is low, and turning on the heater immediately after starting the engine can lead to higher fuel usage. More details are as follows: 1. Small circulation state: In winter, to maintain the interior temperature, the engine mostly operates in a small circulation state. 2. When the heater is turned on: The cold air inside the car quickly flows over the surface of the heat exchanger, effectively adding an efficient radiator to the engine's cooling circulation system. Especially when the external circulation is activated, the cooling effect is significant. The car's computer will then command an increase in fuel injection and adjust the ignition timing to maintain the necessary operating temperature. Therefore, when the car's water temperature has not yet reached normal levels, it will result in increased fuel consumption.
