How to Charge a BAIC New Energy Vehicle?

What is the appropriate RPM for an automatic transmission car?

Automatic transmission engine speed is between 1800 and 2000 RPM. Steps to start an automatic transmission car: 1. Insert the key into the ignition and turn it to the second position (power mode), then wait for the system self-check to complete. 2. Shift the gear lever from P (Park) to N (Neutral). 3. Release the brake and start the car's engine. 4. Press the brake pedal with your foot, shift the gear lever from N to D (Drive), then release the brake and press the accelerator to start moving. Engine maintenance methods: 1. Use high-quality engine oil. 2. Use qualified coolant. 3. Regularly clean the radiator scale. 4. Periodically remove carbon deposits from the engine. 5. Replace the vehicle's air filter, oil filter, and fuel filter on time. 6. Check the condition of the spark plugs. 7. Maintain normal RPM levels.

How to Check Vehicle Pulling to One Side?

Vehicle pulling to one side can occur in the following two situations: 1. During straight-line driving at a constant speed, the vehicle drifts to one side when the steering wheel is released; 2. The vehicle can maintain a straight path without drifting, but the steering wheel is not centered. The causes of vehicle pulling to one side are as follows: 1. Uneven tire pressure between the upper and lower tires. Different pressures result in inconsistent tire circumferences, causing the vehicle to pull toward the side with lower pressure. If the pulling is significantly due to tire pressure, it can often be detected visually. 2. Incorrect toe alignment. Wheel toe alignment primarily refers to the camber angle of the front wheels. Simply put, proper toe alignment creates a "front narrow, rear wide" trumpet shape for the front wheels. Incorrect toe alignment usually results in a "front wide, rear narrow" shape. This issue is often caused by impacts to the front suspension or excessive gaps in suspension links or ball joints. While the primary solution is a four-wheel alignment, the suspension system must first be in good condition. 3. Brake system malfunction. Although brake-related pulling (mainly from the front brakes) is quite subtle, it should be carefully prevented. The most common brake system issue is the front brake caliper not retracting smoothly, which creates resistance to wheel movement.

Is a Hybrid Vehicle Issued a Green License Plate or a Blue One?

Plug-in hybrid vehicles require green license plates, while conventional hybrid vehicles use blue license plates. A plug-in hybrid electric vehicle (PHEV) is a type of new energy vehicle that bridges the gap between pure electric vehicles and traditional fuel-powered cars. It features both the conventional car components—such as the engine, transmission, drivetrain, fuel lines, and fuel tank—and the electric vehicle elements, including the battery, electric motor, and control circuitry. Conventional hybrid vehicles, on the other hand, are equipped with a drivetrain that combines two or more individual power systems capable of operating simultaneously. The driving power is supplied by either system alone or collectively, depending on the actual driving conditions. Below are the key differences between plug-in hybrids and conventional hybrids: Power Supply Method: Plug-in hybrids are characterized by their ability to charge via an external power source, much like pure electric vehicles, whereas conventional hybrids do not require charging. Battery and Fuel Tank Roles: Plug-in hybrids have larger batteries and smaller fuel tanks, primarily relying on the battery for propulsion. In contrast, conventional hybrids feature smaller batteries and larger fuel tanks, with the internal combustion engine serving as the main power source. The battery only provides energy during initial acceleration.

What are the speed grades for cold running-in after an engine overhaul?

Cold running-in starts at a speed of 400r/min to 600r/min and ends at 1000r/min to 1200r/min. The following is an introduction to the engine: 1. Introduction: An engine is a machine that can convert non-mechanical energy into mechanical energy. 2. Classification: Includes internal combustion engines, external combustion engines, jet engines, electric motors, etc.

Divide the Purchase Tax by 11.3 or 11.7?

Vehicle purchase tax is calculated by dividing the invoice price including tax by 11.3. Previously, the tax rate was 17%, and the divisor was 11.7. Here is the relevant introduction: 1. Vehicle purchase tax: Vehicle purchase tax is a tax levied on units and individuals who purchase specified vehicles within the country. It evolved from the vehicle purchase surcharge. 2. Single collection method: Vehicle purchase tax is levied ad valorem based on the taxable vehicle's purchase price declared by the taxpayer. The tax is directly related to the price, with higher-value vehicles taxed more and lower-value vehicles taxed less.

What Do the Markings on Tires Mean?

Tire model numbers and letters explained: Taking 225/60-R17-99H as an example. 1. 225 represents the section width, which can be simply understood as the width of the tire tread. 2. 60 represents the aspect ratio, which is essentially the height of the tire sidewall. 3. R stands for the tire type code, with R indicating a radial tire. 4. 17 represents the rim diameter, meaning the tire is suitable for 17-inch rims. 5. 99 indicates the load index of the tire, which is the maximum weight the tire can bear. 6. H represents the speed rating of the tire, indicating the maximum speed the tire can handle.
