Use an IV bottle to hang the cleaning solution onto the vacuum tube of the running engine, allowing it to be drawn in. The solution burns off and removes carbon deposits in the combustion chamber through combustion. Because the precious metals platinum, rhodium, and palladium inside have deteriorated, cleaning will not restore the exhaust gas purification effect. Commercially available fire lotus ternary catalytic metal soft carriers can be inserted into the exhaust pipe to serve as a replacement for the original ternary catalytic converter carrier.

With twenty years of experience in auto repair, I've encountered excessive carbon monoxide in exhaust emissions all too often. The primary cause is usually a dirty or clogged air filter restricting airflow, leading to incomplete combustion. The solution is straightforward and inexpensive—replace the air filter first, a step you can easily handle yourself. Next, inspect the fuel injectors and throttle body for excessive carbon buildup, using a specialized cleaner to remove deposits. A faulty oxygen sensor is another critical factor; check if its output signal fluctuates—if it's malfunctioning, replacement is necessary. High idle speed can also spike CO levels; a simple screw adjustment can improve this. For a thorough diagnosis, it's best to visit a professional repair shop to analyze ECU data and pinpoint the root cause, saving unnecessary hassle. Regular maintenance, such as replacing filters and cleaning the fuel system every 5,000 kilometers, prevents issues proactively. Exceeding emission limits not only fails annual inspections but also harms the environment—I urge everyone to address these issues promptly without delay.

I once experienced failing the vehicle inspection due to excessive exhaust emissions and was extremely anxious at the time. The solution usually starts with simple steps: try replacing the air filter, as many issues can be alleviated this way. Cleaning carbon deposits from the fuel injectors can be done with additives or manual cleaning. A faulty oxygen sensor is often one of the main culprits, so check its connection and replace it if necessary. Adjusting the idle speed can optimize combustion efficiency. If DIY methods don’t work, take the car to a repair shop for a thorough inspection. This experience taught me to regularly check the filter condition to avoid blockages, use high-quality gasoline to reduce carbon buildup, and perform annual maintenance to prevent issues. Excessive emissions not only cause inspection failures but can also damage the engine and affect fuel efficiency—never overlook safety aspects.

What is the purpose of a roof rack?

Roof racks are primarily used for carrying large items such as bulky luggage, bicycles, or foldable beds that cannot fit into the trunk. Once securely fastened, these items can be easily transported. Additionally, roof racks can serve a decorative and aesthetic purpose. They are typically installed on commercial vehicles and SUVs. After installing a roof rack, it is important to pay attention to the following precautions: 1. Regularly check the tightness of the screws, preferably every 10 days or so, especially before a trip. 2. Secure the cargo on the rack with straps, ensuring even distribution. If the cargo lacks elasticity, use a cargo net. 3. Avoid sudden braking while driving. 4. Do not exceed the rack's designed load capacity, which is generally around 70KG. The exact weight limit may vary depending on the materials and standards used by different manufacturers.

Why was the Vezel 1.5T discontinued?

Due to the overseas pandemic, certain components for the 1.5T engine have not arrived domestically, resulting in the current discontinuation of the 1.5T Vezel. Below is relevant information about the Honda Vezel: 1. The Honda Vezel is a highly popular compact SUV model in the domestic automotive market. 2. In terms of the transmission system, it is paired with a CVT gearbox. Honda's powertrain system is technically mature, providing ample power output while also maintaining fuel efficiency. 3. The comfort level is relatively low. In pursuit of so-called sportiness, the Vezel adopts a stiffer suspension tuning, which significantly reduces ride comfort, especially when driving over uneven road surfaces, where occupants can feel noticeable bumps.

Should the car cover be removed during a typhoon?

It is best not to use a car cover, as the friction between the cover and the car can cause more damage to the vehicle. A car cover, commonly known as a car garment, is a protective outer layer made of canvas or other flexible and durable materials tailored to the car's dimensions. Here is some relevant knowledge about car covers: 1. Composition: A car cover consists of three parts: the body, the straps, and the spring hooks. The front strap is closed and is put on by pulling it over the car's front. The rear strap is open and is secured to the car's rear with a lock that cannot be removed without a special key. The spring hooks on both sides of the cover are then hooked under the car's edges to firmly fix the cover in place. 2. Function: In addition to cleaning and sun protection, car covers have a super water-repellent function, preventing damage from freezing in cold weather. They also effectively protect against falling objects, fireworks, and other accidental factors that could harm the vehicle, as well as deter theft of the car and its accessories.

What Insurances Are Mandatory for New Cars?

New cars must be insured with compulsory traffic insurance, as it is a mandatory requirement for all vehicles in China. Without it, the car cannot be driven on the road and will lose its eligibility for annual inspection. Common car insurance types include compulsory traffic insurance, vehicle damage insurance, third-party liability insurance, passenger liability insurance, comprehensive theft insurance, glass breakage insurance, spontaneous combustion loss insurance, body scratch insurance, and no-deductible insurance. Besides compulsory traffic insurance, it is generally recommended to purchase the following types of car insurance: 1. Vehicle Damage Insurance. In the event of a traffic accident, the insurance company will provide compensation within a reasonable range. 2. Third-Party Liability Insurance. If a motor vehicle is involved in a traffic accident causing personal injury or death and direct property damage to a third party, the insurance company will cover the economic compensation within the legally required scope. 3. No-Deductible Insurance. No-deductible insurance is an add-on to vehicle damage or third-party liability insurance. Purchasing this insurance allows the car owner to avoid bearing the responsibility for accidents themselves and ensures 100% compensation.

How many liters of engine oil should be added to a Volvo XC60?

Volvo XC60 T5 is equipped with three types of engines: b4204t7, b4204t11, and b5204t9. The first one requires 5.5 liters of engine oil, the second requires 5.9 liters, and the third requires 5.5 liters. Below is some relevant information about engine oil: 1. Engine oil refers to the lubricant specifically used in internal combustion engines. Besides lubrication, it also has functions such as cleaning, rust prevention, and cooling. The base oil of currently used engine oil is composed of hydrocarbons, poly-alpha-olefins (PAO), and poly-internal olefins (PIO), all of which are organic compounds consisting solely of carbon and hydrogen. Some high-grade engine oils may contain up to 20% esters. 2. The maintenance cycle varies for each vehicle model. Some require maintenance every three months or 5,000 kilometers, while others require maintenance every six months or 7,500 kilometers, and twelve months or 10,000 kilometers. Whichever comes first, time or mileage, should be followed. Therefore, the amount of engine oil used and the filtration level of the oil filter are also different.
