What are the differences between purchasing a car under a company name and a private name?

Here are the differences between purchasing a car under a company name and a private name: 1. Different payment responsibilities: If registered under a company name, the company should pay for the car. If registered under a private name, the individual usually pays for the car. 2. Different property ownership: If registered under a company name, the car belongs to the company. If registered under a private name, it belongs to the individual. 3. Different impacts on creditors: If registered under a company name, the car is part of the company's legal assets, and creditors of the company's external debts can legally apply to preserve or execute this property. If registered under a private name, the car is personal property, and generally, creditors of the company's debts cannot apply to preserve or execute this property.

Are all commercial vehicles automatic transmission?

Most commercial vehicles are automatic transmission, but there are also manual transmissions. Introduction to automatic transmission: As the name suggests, the driver does not need to shift gears manually. The vehicle will automatically select the appropriate gear based on the driving speed and traffic conditions. Generally, there are six gear positions on an automatic transmission vehicle, from top to bottom: P, R, N, D, S, L. Introduction to manual transmission: A vehicle that uses a manual shift mechanical transmission (also known as manual transmission, MT) to adjust speed. That is, the gear shift lever must be manually moved to change the gear meshing position inside the transmission, thereby changing the transmission ratio to achieve speed adjustment. The gear lever can only be shifted when the clutch is depressed.

How Long Can the License Plate Be Reserved After Vehicle Transfer in Guangzhou?

In Guangzhou, if the owner has held the motor vehicle for more than 3 years, they can apply to reserve the license plate for 6 months when transferring the vehicle. Transfer Process: The used vehicle market implements an agency system for vehicle transfers, where the transfer window does not directly handle transactions for consumers. After driving the vehicle to the market, a used vehicle agency company will complete the transfer procedures on behalf of the owner: evaluation, vehicle inspection, and issuing receipts. Additional Fees: After the vehicle transfer, the owner needs to change the registration for road maintenance fees, purchase tax, and insurance. This can be done with the original vehicle registration certificate.

What is the compression pressure of a gasoline engine?

The compression pressure of a gasoline engine is between 9 and 12 bar. Typically, engines with low compression ratios are below 10 bar, while those with high compression ratios exceed 10 bar. Older gasoline engines have compression pressures ranging from 6 to 10 bar. The compression ratio of a gasoline engine refers to the degree to which the engine's air-fuel mixture is compressed, which is the ratio of the total cylinder volume before compression to the cylinder volume after compression. The volume formed by the engine piston moving from the lowest position to the highest position represents the smallest volume during the entire piston stroke. The compression ratio to be calculated is the ratio of the maximum stroke volume to the minimum volume.

Are Car Shock Absorber Spacers Effective?

Their main function is to reduce vehicle body roll when cornering. Here are specific details about car shock absorber spacers: 1. Raising the vehicle height: For weakened springs that cause significant body lowering when compressed, installing buffer spacers can provide support and relieve pressure on the springs. This can be understood as effectively raising the vehicle height, typically by 0.2-0.3 cm or more, depending on spring spacing and degree of fatigue. 2. Shock absorption function: The primary role of automotive spring buffer spacers is to provide cushioning and shock absorption while protecting the shock absorbers. By utilizing the hydraulic spring damping function, these spacers act as buffers during sudden impacts, thereby reducing collision damage and improving safety for both the vehicle and occupants.

What Causes the Engine Fault Light to Illuminate in a New Car While It Can Still Run Normally?

When the engine fault light comes on, it may serve as a warning indicating that certain system parameters in the vehicle might have exceeded the set range. In such cases, the vehicle can usually continue to operate, and the light is typically yellow. There is also a more severe situation where the light turns red, signaling a very serious fault. Although the vehicle might still be drivable, it is crucial to stop immediately, turn off the engine, and refrain from further driving for safety reasons, followed by a thorough inspection to identify the fault. The engine fault light may illuminate due to the following seven main reasons: Sensor Malfunction: Sensors such as those for coolant temperature, crankshaft position, air flow, intake air temperature, and oxygen sensors may become damaged, have poor connections, or experience signal interruptions. When the vehicle's ECU cannot accurately obtain engine data due to these issues, the engine fault light will illuminate. Fuel or Oil Quality Issues: Failure to use the fuel or oil as specified by the manufacturer may lead to engine wear, triggering the fault light. Poor Combustion of Air-Fuel Mixture: Incomplete combustion can cause engine carbon buildup or knocking. Once detected by the oxygen sensor and reported to the ECU, the fault light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can lead to poor combustion. Turbocharger Problems: Issues with the intake boost system or turbocharger can also cause the engine fault light to come on. The most common problem is a damaged turbocharger, often accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake Issues: Problems with the vehicle's air intake system may lead to clogged engine passages, and in severe cases, trigger the engine fault light. A dirty or uncleaned air filter can cause intake problems. Exhaust System Issues: Faults in the exhaust system, such as problems with the rear oxygen sensor, catalytic converter, exhaust camshaft, or bearings, can also cause the engine fault light to illuminate. The catalytic converter is the most common culprit, often affected by the use of leaded gasoline, lead- or silicon-based lubricant additives, physical damage, or fuel system malfunctions. Anti-Theft System Fault: If the vehicle's electronic anti-theft system malfunctions or if there is a mismatch between the anti-theft controller and the engine control unit, the engine may fail to operate correctly, and the fault light will illuminate. If the engine fault light comes on, follow these steps: First, check whether the engine is running normally and if there are any issues like shaking or smoke. If such problems exist, avoid restarting the engine. Notably, if the light is red, do not attempt to restart the engine under any circumstances. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'ON' position (without depressing the clutch). The vehicle will perform a self-check upon powering up. Observe whether the fault light turns off after 5-10 seconds. If the light remains on, visit a service center as soon as possible. Technicians can use a portable diagnostic tool to read the fault codes, identify the issue, and perform targeted repairs.
