The differences between dry and wet transmissions: 1. The working environment of the clutch plates differs: In a dry transmission, the clutch plates transmit torque in the natural environment inside the transmission; in a wet transmission, the clutch plates are immersed in oil to transmit torque. 2. The cooling methods for the clutch plates differ: Dry transmissions rely entirely on natural cooling, while wet transmissions use transmission oil for cooling and heat dissipation. 3. The contact method between the friction plates and the engine flywheel differs: In a dry transmission, the contact between the friction plates and the engine flywheel is almost the same as in a manual transmission, meaning the friction plates and flywheel engage in dry friction; in a wet transmission, the contact between the friction plates and the flywheel occurs while immersed in hydraulic oil.

What are the differences between National 5 and National 6 vehicles?

The differences between National 5 and National 6 vehicles are: 1. Different emission limits: The National 5 standard sets the carbon monoxide limit at 1000 milligrams per kilometer; the National 6a standard requires a carbon monoxide limit of 700 milligrams per kilometer, while the National 6b standard is only 500 milligrams per kilometer. 2. Different release dates: The National 5 standard was released on September 17, 2013; the National 6 standard was released on June 22, 2018. 3. Different issuing departments: The National 5 standard was issued by the Ministry of Environmental Protection; the National 6 standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine. 4. Different requirements: During the National 5 phase, diesel and gasoline vehicles had different emission standards; National 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type.

What to Do When the Car Warning Light Comes On?

When the car warning light comes on, you need to go to a 4S shop or a professional repair facility to read the fault code and check the specific cause and location of the fault. Car warning lights are divided into: 1. Engine malfunction indicator light: used to display the working condition of the vehicle engine; 2. Oil indicator light: used to show the oil pressure during engine operation; 3. Water temperature indicator light: used to show the circulating temperature of the coolant in the vehicle engine; 4. ABS indicator light: used to display the operating status of the anti-lock braking system; 5. Airbag indicator light: used to show the operating status of the airbag; 6. Fuel indicator light: used to remind the vehicle driver to refuel the vehicle in time.

Where to Check National V or National VI on a Vehicle?

Methods to check whether a vehicle is National V or National VI: 1. Refer to the relevant information on the conformity certificate; 2. Look at the environmental protection label affixed to the upper right side of the vehicle's front windshield; 3. Carefully check the vehicle conformity certificate. The difference between National V and National VI vehicles lies in the fact that National VI vehicles use a three-way catalytic converter, allowing the engine's exhaust emissions to meet the National VI standard, while the engine and the vehicle itself remain the same. The national requirement is that all new vehicles sold must comply with the National V emission standard to be registered and sold. The National V emission standard is marked with a 'V', and the National VI emission standard is marked with a 'Ⅵ', both using Roman numerals. The difference between National V and National VI vehicles is mainly reflected in the reduction of harmful substances in exhaust emissions. The transition from National V to National VI emission standards shows a difference in carbon monoxide emissions, decreasing from 1000 milligrams per kilometer to 700 milligrams per kilometer, a reduction rate of thirty percent.

What to Do When the Engine Warning Light Is On and the Car Shakes?

If the engine warning light is on and the car shakes, you should call a 4S shop or a professional auto repair shop for help, request a tow truck or wait for rescue, and avoid risking continued driving. Reasons for the engine warning light being on and the car shaking: The ignition system malfunctions, with issues in the working conditions of spark plugs, high-voltage wires, and ignition coils, leading to poor ignition system performance; An overly rich air-fuel mixture in the cylinders may cause symptoms such as knocking and shaking. The engine (Engine) is a machine capable of converting other forms of energy into mechanical energy, originated in the UK, and it can refer to both the power generation device and the entire machine including the power unit.

How Often Should Drum Brakes Be Replaced?

Drum brakes should be replaced every 60,000 kilometers. If the brake pads wear down to the warning indicator or are found to be worn down to 2-3 millimeters during maintenance, they should be replaced immediately. The tools required for replacing brake pads include a jack, suitable socket wrenches, a box-end wrench, a screwdriver, sandpaper, and lubricating grease. The specific steps for replacing drum brakes are as follows: 1. Remove the rear brake drum: After removing the tire, the brake drum will be visible. Use a hammer to tap the surface of the brake drum to loosen it before removal. 2. Insert a flat-head screwdriver into the gap of the spring and pry upwards to remove the return spring. 3. Use pliers to remove the fixing bolts of the brake pads. There are two brake pads and two fixing bolts on the wheel. 4. After removing both front and rear brake pads, the brake pads will automatically fall off the brake assembly. 5. Install new brake pads: Remove the locating pins from the old brake pads and install them on the new ones. Assemble both sides before installing them onto the brake assembly. 6. Adjust the handbrake height and complete the installation of the new brake pads.

What does the vehicle identification number mean?

Vehicle identification number is the ID number of a car, which is determined according to national vehicle management standards and contains information such as the manufacturer, year, model, body type and code, engine code, and assembly location of the vehicle. Here is some introduction about the vehicle identification number: 1. Introduction: Vehicle Identification Number (VIN), VIN is the abbreviation of Vehicle Identification Number. Because the ASE standard stipulates that the VIN code consists of 17 characters, it is commonly known as the seventeen-digit code. Correctly interpreting the VIN code is very important for correctly identifying the vehicle model and performing correct diagnosis and maintenance. 2. Description: The vehicle identification code should consist of three parts: the first part, the World Manufacturer Identifier (WMI); the second part, the Vehicle Descriptor Section (VDS); the third part, the Vehicle Indicator Section.
