Do I need to remove items from the car for the annual inspection?

It is not necessary to remove items from the car for the annual inspection. Here are some key points to note about vehicle annual inspections: 1. Check whether the engine, chassis, body, and related equipment are clean, complete, and functional, whether the paint is uniform and aesthetically pleasing, whether major components have been replaced, and whether they match the initial inspection records. 2. Verify that the vehicle's braking system, steering control, lights, exhaust, and other safety features comply with the "Technical Conditions for Safe Operation of Motor Vehicles." 3. Confirm whether the vehicle has undergone modifications or alterations, and whether the registration details in the driving license, license plate, and vehicle records match the current condition of the vehicle, including any changes and whether approval and modification procedures have been completed.

How to Clean Carbon Deposits in the Combustion Chamber?

Methods for cleaning carbon deposits in the combustion chamber are as follows: 1. Mechanical Method: This involves using steel wire brushes, scrapers, bamboo chips, or sandpaper to remove carbon deposits and oil stains. Special brushes and scrapers can be customized according to the shape of the parts to be cleaned. For example, fine copper wire brushes can be used to clean carbon deposits and oil stains around the injector nozzles; a specialized copper wire needle can be inserted into the pressure chamber to scrape off carbon deposits; cylindrical metal brushes can be used to remove carbon deposits and oil stains from valve guides and valve seats. 2. Walnut Shell Blasting Method: This method uses high-speed airflow to blast crushed walnut, peach, or apricot shell particles onto the part surface to remove carbon deposits and oil stains. This method is highly efficient and thorough, but it requires specialized equipment to generate high-speed airflow, making it relatively costly and thus not widely adopted. 3. Chemical Method: This involves using a chemical solvent or carbon remover to soften the carbon deposits and oil stains on the part surface, causing them to lose their adhesion to the metal, and then removing the softened carbon deposits. This method is highly efficient, effective, and less likely to damage the part surface. 4. Adding Diesel Additives: Most additives contain chemical components that can clean carbon deposits and oil stains. When the vehicle's condition is poor, adding the additive twice can effectively clean carbon deposits and oil stains in the engine combustion chamber, intake manifold, and fuel system, while also improving fuel quality.

How Deep Should a Steel Wool Ball Be Inserted into the Exhaust Pipe?

Back pressure reaches around 35kp, calculated based on a 10 cm exhaust pipe opening. The following are the impacts of blocking the exhaust pipe: 1. Automatic transmission vehicles will downshift: When the exhaust pipe is blocked, automatic transmission vehicles experience a decrease in engine power and may downshift, which is caused by the blocked exhaust pipe. 2. Reduced acceleration power: The inability to expel exhaust gases leads to incomplete combustion, resulting in symptoms like reduced acceleration when the exhaust flow is obstructed. 3. Abnormal noises: Typically, abnormal noises from the exhaust system may also indicate excessive exhaust emissions. If left unaddressed for a long time, it may damage other components of the vehicle.

What is the general maximum idle speed of an engine?

Engine idle speed limit is generally 5000 RPM. Internal combustion engines have a normal operating RPM range: Typically for small cars with 1.5~3.0L displacement, the RPM ranges between 1500~3000, with the most common being around 2000 RPM. Ordinary engines reaching 5000 RPM is basically the limit, while high-performance engines can reach 7,000 to 8,000 RPM. Premium models feature idle protection: Generally, higher-end vehicles are equipped with idle protection function. When pressing the accelerator during idle, the engine RPM won't increase - this is the engine protection feature of the vehicle.
