Steps for automotive fuel system cleaning (IV drip cleaning): 1. Open the hood, remove the vehicle's fuel pump fuse, and add ultra-concentrated fuel injector cleaner to the no-disassembly fuel system cleaning equipment; 2. Add the cleaning solution and hang the pressurized equipment on the vehicle's front hood; 3. Place a cloth beneath the fuel line, slowly disconnect the fuel inlet pipe, connect it to the equipment's fuel line, and start the engine of the vehicle being cleaned after confirming everything is correct. IV drip cleaning is now a very common maintenance method, primarily used for cleaning the engine's intake tract and fuel system. The advantages of this method include convenience and speed, as it can thoroughly clean the engine without disassembly, achieving excellent results.

In my daily routine of car maintenance, performing an engine carbon cleaning with a drip bottle is a common procedure. The steps are generally as follows: First, ensure the vehicle is in a safe condition, such as being parked with the engine off and the handbrake engaged, to prevent any movement that could cause danger. Then, prepare the drip bottle equipment, including the cleaning agent, input tube, and bottle, checking for proper sealing to avoid leaks. Next, connect the equipment to the engine's intake system interface, such as the throttle position, ensuring the pipes are secure to prevent detachment. Start the engine and let it idle at around 800 RPM, then slowly inject the cleaning agent, controlling the flow rate to about a small segment per minute, avoiding too fast a flow to prevent damage to internal components. The entire process lasts 10-15 minutes, during which observe any changes in the engine. After completion, turn off the engine, remove the equipment, clean up the area, and run the vehicle for a few minutes to expel exhaust gases. I recommend checking monthly or based on mileage to maintain engine efficiency and reduce emissions, but if you're not familiar with the process, it's best to have it done by a professional shop.

Will There Be a Popping Sound When Starting with Rusty Brake Discs?

Starting with rusty brake discs can produce a popping sound. Brake systems include disc brakes, drum brakes, and air brakes. Disc brakes offer better heat dissipation compared to drum brakes, making them less prone to thermal fade during high-speed braking, thus providing superior high-speed braking performance. However, their braking effectiveness at low speeds with cold brakes is inferior to drum brakes. Light rust on the brake disc surface: If there is only light surface rust, it can typically be removed by applying the brakes multiple times while driving. No special treatment is required, as minor rust on the brake discs will naturally wear off during normal braking. Severe rust on the brake disc surface: If the rust is more severe, it may cause vibrations or shaking during braking, such as brake pad vibration, steering wheel vibration or shaking, or body tremors. In such cases, it is advisable to take the vehicle to a repair shop, remove the brake discs, and sand the rust off thoroughly. The brake pads should also be inspected for any abnormalities. After proper reinstallation, a road test should be conducted. The road test involves driving at a speed of 70 km/h on a flat road and performing multiple brake applications to ensure no abnormalities are present. Precautions for brake disc usage: To maintain brake discs, it is recommended to perform maintenance every two months to prevent severe rust development. If vibrations persist after sanding the brake discs, it indicates an uneven surface, which may require further polishing or, depending on the situation, replacement.

Will you be penalized for occupying the overtaking lane on the highway for a long time?

Occupying the overtaking lane for a long time will result in penalty points. According to the "Road Traffic Safety Law," on highways, especially in the overtaking lane, driving below the minimum speed limit or occupying the overtaking lane for an extended period under normal driving conditions are considered illegal acts, punishable by a 3-point deduction and a fine. The overtaking lane is located in the leftmost lane of the highway. It is only set up when the road meets the standards of a bidirectional six-lane highway. The overtaking lane is designed for vehicles that need to overtake or those traveling at the required speed. However, some drivers occupy the overtaking lane for long periods, forcing vehicles that need to overtake to do so from the relatively slower main lanes. This increases the speed difference between the overtaking vehicle and the vehicles in the main lane, raising the risk of traffic accidents. Precautions for driving on highways: When merging, do not obstruct vehicles traveling in the main lane; always pay attention to roadside and road signs and markings, and drive appropriately to the right, avoiding straddling lanes; maintain a safe longitudinal distance between vehicles, increasing the distance in special weather conditions; when overtaking, estimate the distance and speeds of both vehicles, and under normal conditions, signal left, sound the horn, and overtake from the overtaking lane—overtaking from the right is prohibited.

Can a Deteriorated Three-Way Catalytic Converter Still Be Used?

A deteriorated three-way catalytic converter should not continue to be used. When a car's three-way catalytic converter deteriorates, it becomes ineffective, leading to poor engine exhaust flow and excessive tailpipe emissions. The best solution is to replace it with a new one. Cleaning the Three-Way Catalytic Converter: The cleaning method for a three-way catalytic converter is known as the "drip cleaning" process. This involves connecting a plastic hose to the engine's vacuum solenoid valve and using the air pressure in the hollow tube to draw cleaning fluid from an infusion bottle into the engine. As the cleaning fluid exits through the exhaust pipe, it cleans the three-way catalytic converter. Lifespan of the Three-Way Catalytic Converter: The typical lifespan of a three-way catalytic converter is between 80,000 to 100,000 kilometers. The exact lifespan depends on the vehicle's usage conditions, as well as the quality of fuel used and the driving environment.

What documents are required for car transfer procedures?

Documents required for car transfer: ID card, vehicle license, original purchase invoice, and sales contract. Below is an introduction to car transfer and its principles: Introduction to car transfer: Vehicle transfer refers to changing the name of the vehicle's owner. When purchasing a used car, apart from checking the car's condition, the most important step is completing the transfer procedures. Principles of car transfer: Every car has a fixed registration, which primarily records the car's owner, address, and some related car parameters. Transferring a car proves that the car belongs to the current owner and has no accidents or violations. If the car has issues, such as being involved in an accident, failing annual inspection, being stolen, or being smuggled, it cannot be transferred through normal procedures.

Does the Three-Way Catalytic Converter Affect Fuel Consumption?

The three-way catalytic converter does affect fuel consumption. Its primary function is to influence vehicle emissions. Lower emissions indicate more complete gasoline combustion, leading to better fuel efficiency. Conversely, if the catalytic converter fails, emissions increase, gasoline cannot burn or be utilized efficiently, and fuel consumption naturally rises. Methods to determine the condition of the three-way catalytic converter: Visual inspection. Examine the exterior of the catalytic converter for any damage or discoloration. Scratches, cracks, or other external marks may indicate prior damage. If there are noticeable gray spots on the protective cover, severe discoloration, or purple marks on the casing, the catalytic converter may have suffered from overheating issues. Check the engine exhaust. Place your hand near the tailpipe outlet to feel the exhaust flow and assess whether the catalytic converter is clogged or if there are exhaust flow issues. Another method is to open the air filter, remove the filter element, and observe if exhaust gases flow backward during rapid acceleration, indicating poor exhaust flow. To evaluate the TWC's condition, also inspect the secondary air injection pump for faults. Use an infrared thermometer. Compare the temperature difference between the front and rear of the TWC using an infrared thermometer. If the temperature difference between the inlet and outlet of the catalytic converter is less than 10°C, the TWC is likely damaged.
