What Causes Engine Idle Shaking and Lack of Power During Acceleration?

Reasons for engine idle shaking and lack of power during acceleration: Excessive carbon buildup in the throttle body leading to restricted air intake. As carbon deposits accumulate, fuel passages become blocked, engine performance declines, fuel consumption increases, and a series of complications may follow. Gasoline is refined from heavy oil with high sulfur and acid content, containing elevated levels of sulfur, carbon, manganese, and trace metals. High-impurity gasoline leaves sticky residues on combustion surfaces after burning, forming carbon deposits on piston tops and combustion chamber walls. There are primarily two methods to remove carbon deposits: 1. Manual cleaning of internal carbon buildup; 2. Using fuel additives to improve combustion and clean carbon deposits. Manual cleaning requires engine disassembly, which is complex and potentially damaging to the engine.

Should tires be replaced after seven years and 30,000 kilometers?

Tires with seven years of use and 30,000 kilometers should be replaced. The typical lifespan of tires is 3-5 years or within 80,000 kilometers. Since tires are rubber products, they will gradually age and deteriorate in performance even if the car remains parked in a garage and unused. Therefore, for safety reasons, it is essential to replace tires promptly. Technical standards: Tires should be replaced when the tread grooves are less than 1.6 mm deep. If the tread wear indicators are exposed, it indicates that the remaining groove depth is less than 1.6 mm. The tread wear indicators are the raised bars within the grooves. Using tires with groove depths below 1.6 mm can lead to sudden loss of traction and braking power in rainy conditions, as well as a complete loss of traction in snowy conditions. Mileage standards: For mixed road conditions, tires should be replaced after 30,000-50,000 kilometers. On smooth asphalt roads, replacement is recommended at 50,000 kilometers, while on rough gravel roads, it should be done at 30,000 kilometers. Beyond 30,000 kilometers, the tread friction coefficient drops below 50. On wet or snowy roads, the tread's grip and drainage capabilities diminish or disappear entirely, with the friction coefficient falling below 15, increasing the risk of tire blowouts on gravel roads.

Can I Buy a Company-Registered Motorcycle in Beijing?

Company-registered motorcycles in Beijing are available for purchase. These motorcycles are registered under a company or organization with legitimate business qualifications. Theoretically, the legal holder of the vehicle is the company it is registered under, not the actual purchaser. There are no requirements regarding the buyer's household registration address. However, before purchasing a company-registered motorcycle, it is essential to verify whether the company under which the motorcycle is registered still exists. If the company no longer exists, selling the motorcycle later may become complicated. Differences in Vehicle Ownership: If a motorcycle is registered under a company (public registration), the name on the vehicle registration certificate will be the company's name. For privately registered motorcycles, the name on the registration certificate is the owner's personal name. Vehicle Transfer Process: For company-registered motorcycles, the transfer of ownership only requires the completion of payment and handover of the vehicle, without needing to go through the vehicle management office for transfer procedures. However, privately registered motorcycles require both the buyer and seller to bring relevant documents to the vehicle management office to complete the transfer process. Insurance Claims: In the event of a traffic accident, insurance companies typically deposit claim payments into the company's public account (the registered entity). This adds an extra step for the actual motorcycle user, making the process more cumbersome. Therefore, if a motorcycle is company-registered, it is important to distinguish between the insured person and the registered company when purchasing insurance. Loss of Vehicle License or Registration Certificate: If the license plate or registration certificate of a company-registered motorcycle is lost, the owner must provide their ID card, vehicle registration certificate, and the company's "Organization Code Certificate" or a power of attorney stamped with the company's official seal, along with the authorized person's ID, to apply for a replacement. It is crucial to stay informed about the company's status to avoid complications arising from the deregistration of the registered company.

How to Check Whether the Engine is China 5 or China 6?

Methods to check whether the engine is China 5 or China 6: 1. The simplest and most straightforward way is to look at the vehicle's environmental protection label, which has clear markings; 2. You can log in to the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center and enter the relevant number to query; 3. You can bring the original or a copy of the motor vehicle registration certificate to the Motor Vehicle Administration for inquiry. The main pollutants emitted by vehicle exhaust include hydrocarbons, nitrogen oxides, carbon monoxide, particulate matter, etc., which are primarily discharged through the vehicle's exhaust pipe. Due to the increasing harm caused by vehicle emissions to the environment, countries and regions around the world have successively established limits to restrict vehicle exhaust emissions.

What are the English letters for cruise control?

The English letters for cruise control are CCS. Many cars are equipped with a cruise control system, which can be used when driving on highways. After entering the highway, the driver can activate the cruise control system and no longer needs to continuously press the accelerator pedal, as the car will maintain a fixed speed. Cars equipped with adaptive cruise control have a ranging radar located below the front bumper. This radar can detect the distance between the car and the vehicle ahead. If the distance becomes too close, the car will automatically brake. Vehicles with adaptive cruise control can also achieve automatic following functionality, which is particularly useful in traffic congestion.

Why is the car's air conditioning heating not hot?

The reasons why the car's air conditioning heating is not hot: 1. The thermostat is always open or opens too early, causing the cooling system to start the large circulation prematurely. When the external temperature is very low, especially while driving, cold air quickly cools the antifreeze, preventing the engine water temperature from rising and the heating from getting warm; 2. If the water pipe of the small heating radiator is very hot but the outlet pipe is cold, this situation indicates a blockage in the small heating radiator, which should be replaced; 3. There is airlock in the engine cooling system. Airlock is caused by poor circulation in the cooling system, leading to excessively high water temperature and the heating not getting warm. If the cooling system always has gas, it is likely that the cylinder gasket is damaged, allowing gas to enter the cooling system pipe column.
