What is the displacement limit for China 6?

What are the classifications of automatic transmissions?

Automatic transmissions include electronically controlled hydraulic automatic transmissions, electronically controlled mechanical automatic transmissions, electronically controlled continuously variable transmissions, and dual-clutch transmissions. The following is an introduction to the relevant content: An automatic transmission consists of a torque converter, a gear transmission mechanism, an oil supply system, an automatic shift control system, and a shift operating mechanism. The fault diagnosis methods for automatic transmissions are: 1. After the engine is warmed up, shift into P or N gear, turn off the air conditioning, and check the idle speed. 2. Check the throttle position cable and sensor. 3. Check the quality of the automatic transmission fluid. 4. Shift into P or N gear and push the vehicle. 5. Check the P or N gear start switch. 6. Move the gear lever from the P position to other positions one by one to check if the gear lever moves smoothly.

What is the method for repairing cracks in a car windshield?

Here are the steps to repair cracks in a car's front windshield: 1. Use a vacuum injector to remove the air from inside the glass. 2. Fill the crack with a glass repair agent. 3. Use an ultraviolet lamp to irradiate for two minutes to solidify the repair solution. 4. Drop a high-concentration repair agent and cover it with a glass piece. 5. Use a blade to level the surface, apply polishing agent, and polish with a cloth. Steps to replace the front windshield: 1. Use a screwdriver to remove the black protective strips around the windshield. 2. Use a steel wire to pull apart the sealant around the entire windshield. 3. Use a small blade to scrape off any black sealant remaining on the car. 4. Apply polyurethane sealant to the windshield frame. 5. Install the windshield.

How Long Can Vehicle Inspection Be Postponed?

Vehicle inspection can be delayed for a maximum of 1 month. Below are the inspection intervals for different types of vehicles: 1. For passenger transport vehicles within 5 years, inspection is required once a year; for those over 5 years, once every 6 months; 2. For trucks and large or medium-sized non-passenger transport vehicles within 10 years, inspection is required once a year; for those over 10 years, once every 6 months; 3. For small and mini non-passenger transport vehicles within 6 years, inspection is required once every 2 years; for those over 6 years, once a year; and for those over 15 years, once every 6 months. Additional information: The vehicle inspection process refers to the fixed procedure that motor vehicles must undergo annually, which is a mandatory test for every vehicle.

Where is the car battery switch located?

Currently, most car batteries in use are maintenance-free batteries, which do not have a switch cover and cannot be opened as they are sealed. Below is more information about maintenance-free batteries: 1. Maintenance-free batteries are made with lead-calcium alloy grids, designed with the latest fully sealed structure and modern production processes from the 1990s. 2. These batteries decompose less water during charging, have lower water evaporation, and release fewer sulfuric acid gases. They do not require adding any liquid electrolyte, have a longer storage time, and compared to traditional batteries, they offer superior qualities such as high performance, maintenance-free operation, safety, reliability, and a long service life. 3. The lifespan of maintenance-free batteries is twice that of ordinary batteries. They continuously convert electrical energy and chemical energy during the charging and discharging processes to provide power for the car, belonging to the category of secondary batteries.

How to Determine if a Car Scratch Has Reached the Primer?

Methods to determine if a car scratch has reached the primer include: 1. Visual inspection—the primer color is opposite to the car paint color, so a scratch will show a noticeable color difference; 2. Run your fingernail over the scratch—if it feels slightly rough and indented, it indicates the primer is damaged; 3. Check if the scratched area has rusted. The main function of the primer is to enhance the smoothness of the car's surface, ensuring the topcoat appears more vibrant and adheres better. Car paint maintenance methods: 1. Promptly remove dust from the car body to minimize static electricity attracting dust; 2. Rinse off rain stains with clean water after rainfall; 3. When wiping, follow the direction of water flow from top to bottom.

What is the Principle of Drum Brakes?

Drum brakes operate by using stationary brake shoes inside the brake drum to create friction against the rotating drum, which is connected to the wheel, thereby reducing the wheel's rotational speed. Below are some advantages of drum brakes: 1. Function: Drum brakes have excellent self-braking properties. As the brake shoes expand outward, the rotation of the wheel causes the expanding brake drum to twist slightly (though not enough to be easily noticeable). The greater the outward tension of the brake shoes (braking force), the more pronounced this effect becomes. Therefore, drum brakes are commonly used in large vehicles, not only because they are more cost-effective but also because the main difference between drum brakes in large and small vehicles is that large vehicles often use pneumatic assistance, while small vehicles use vacuum assistance to aid braking. 2. Lower Cost: The manufacturing technology for drum brakes is less complex, and they were the first type of braking system used, making them cheaper to produce compared to disc brakes. 3. Installation: The handbrake mechanism is easier to install. Some models with rear disc brakes may still incorporate a drum brake handbrake mechanism in the center of the brake disc.
