Can the Vehicle License Show the National Emission Standard?

Methods to check the national emission standard on the vehicle license: Directly check the vehicle model number on the license. 'Y' indicates the National IV emission standard, and 'V' indicates the National V emission standard. However, after testing by most people, it has been confirmed that this method is not applicable to all vehicle models. Other methods to check the emission standard: 1. Vehicle's environmental protection label: The simplest and most direct method is to look at the vehicle's environmental protection label, which has clear markings on the back. 2. Factory certificate: For new vehicles, you can check the vehicle's factory certificate or vehicle conformity certificate. 3. Query platform: You can also log in to the public query platform of the Motor Vehicle Environmental Protection Network, enter the vehicle's VIN number (Vehicle Identification Number) and the last 6 digits of the engine number to query vehicle information.

What Causes the Abnormal Noise When Releasing the Brake at Car Start?

Abnormal noise when releasing the brake at car start is due to damage in the brake system. The specific reasons are as follows: 1. Brake Pads: Abnormal clearance in the brake pads. 2. Brake Disc: Uneven hardness of the brake disc, affecting the uneven surface of the brake pads. 3. Braking: Release the brake once before the vehicle comes to a complete stop, then lightly apply the brake until the vehicle stops moving. 4. Engine Braking: When braking while the vehicle is in a curve, reduce the speed sufficiently through braking. However, if it's too late to slow down, the brake can be used briefly according to the situation. Emergency braking on slippery curved roads can easily cause the tail to swing out, which can be mitigated by downshifting the gearbox and utilizing engine braking to slow down.

When Should Engine Oil Be Changed Based on Color?

Engine oil must be replaced when it turns deep black. Below are specific methods for selecting engine oil for your car: 1. Performance selection: If you prioritize the long-term effectiveness of the oil, you can choose Mobil oil; if you focus on the oil's cleaning ability for the engine, you can use Shell lubricants; if you need lubricants with strong oil film toughness, it is recommended to use Castrol. 2. Driving conditions: If you frequently drive in congested areas, have an older vehicle, or operate heavy-duty vehicles for long-distance transportation, the viscosity of the lubricant can be appropriately increased. 3. Engine type: For naturally aspirated engines, you can choose mineral oil or semi-synthetic oil. Compared to naturally aspirated engines, turbocharged engines have a more compact structure and operate under harsher conditions, requiring higher-quality lubricants with better fluidity, preferably full synthetic oil.

What is the normal cylinder pressure for a car engine?

Automobile engine cylinder pressure is around 1000kpa. Generally, gasoline engines are around 1000kpa, diesel engines are around 2000kpa, most fuel injection engines have cylinder pressures between 1200~1400kPa, and a few high-compression ratio engines have cylinder pressures above 1700kPa. A cylinder is a part of the car's combustion chamber where there is a piston pushed by the pressure or expansion force of the working fluid. The classification of cylinders is as follows: 1. Single-acting cylinder: Only one end has a piston rod, with air supplied from one side of the piston to generate pressure, which pushes the piston to extend, and returns via spring or self-weight. 2. Double-acting cylinder: Air is alternately supplied from both sides of the piston, outputting force in one or two directions. 3. Diaphragm cylinder: Uses a diaphragm instead of a piston, outputting force in only one direction, with spring reset. It has good sealing performance but a short stroke.

What are the steps for bumper removal and installation?

Here is the method for removing the bumper: 1. Park the vehicle on a lift, take safety measures, and raise the vehicle to an appropriate height. 2. Remove the bolts on the left and right sides of the rear bumper. 3. Pull the rear bumper out parallel from the guide channel, completing the bumper removal. Here is some related information: 1. Traditional bumpers: The car bumper is a safety device designed to absorb and mitigate external impacts, protecting the front and rear of the vehicle body. Twenty years ago, front and rear bumpers of cars were primarily made of metal materials, using steel plates over 3mm thick pressed into U-shaped channels, with chrome-plated surfaces, riveted or welded to the frame longitudinal beams, leaving a significant gap from the body, appearing as an additional component. 2. Modern bumpers: With the development of the automotive industry, car bumpers, as an important safety device, have also evolved. Today's front and rear bumpers not only maintain their original protective functions but also strive for harmony and unity with the vehicle's styling and pursue lightweight design.
