Cleaning the three-way catalytic converter is useful: 1. Based on an analysis of the content of rare and precious metal materials involved in the reaction within the three-way structure of the vehicle and the fuel grade, it is generally recommended to clean and maintain the three-way catalytic converter every 30,000 kilometers. This maintenance can also remove carbon deposits from the fuel injectors, intake valves, combustion chambers, and chemical complexes attached to the oxygen sensors and the three-way catalytic converter. It can reactivate the purification function of the three-way catalytic converter while significantly reducing the CO, HC, and NO emissions from the vehicle's exhaust. It can also address issues such as reduced power and increased fuel consumption caused by carbon deposits in the fuel injectors, deposits in the intake system, and poor exhaust flow through the three-way catalytic converter. This maintenance can extend the lifespan of the existing three-way catalytic converter from 350,000 kilometers to 1,020,000 kilometers; 2. Due to the mismatch between China's fuel and closed-loop fuel injection vehicles, the high sulfur content and poor quality of the fuel, as well as frequent stop-and-go driving in congested roads, incomplete fuel combustion leads to more emissions. After driving for a period, the three-way catalytic converter will inevitably accumulate a large number of chemical complexes, causing blockage. If not cleaned and maintained in time, this will result in reduced vehicle power, increased fuel consumption, and excessive exhaust emissions; 3. Severe blockage can cause the working temperature of the three-way catalytic converter to rise from several hundred degrees to over a thousand degrees (normally 810 degrees Celsius), leading to high-temperature sintering and complete damage. This can cause the exhaust pipe to glow red and may even lead to vehicle self-ignition;

What are the harmful gases emitted by cars?

Automobile exhaust pollution is environmental pollution caused by the exhaust gases emitted by vehicles. The main harmful gases emitted include hydrocarbons, nitrogen oxides, carbon monoxide, and sulfur dioxide. Carbon Monoxide: Carbon monoxide is an intermediate product of hydrocarbon fuel combustion. Inhaling excessive amounts of carbon monoxide can cause shortness of breath, purple lips, difficulty breathing, and even death. Nitrogen Oxides: Nitrogen oxides are mostly generated in the combustion chamber of an internal combustion engine. The emission of nitrogen oxides depends on factors such as combustion temperature, time, and air-fuel ratio. Nitrogen dioxide is a reddish-brown respiratory irritant gas that has a significant impact on human health. Hydrocarbons: Methane is an asphyxiant gas with an odor threshold of 142.8 mg, and it only poses a health hazard at high concentrations. Ethylene, propylene, and acetylene primarily harm plants, preventing roadside trees from growing normally. Sulfur Dioxide: When the concentration of sulfur dioxide in automobile exhaust is too high in the atmosphere, it can form acid rain with precipitation. Acid rain damages forests and severely affects the living environment of wildlife.

Must a Pair of Shock Absorbers Be Replaced If One Is Broken?

If one car shock absorber is broken, it is necessary to replace the pair together. This is because shock absorbers of different models have varying parameters, and if the specifications on the left and right sides are different, it can lead to imbalance between the two sides of the car during driving, affecting the vehicle's driving safety. The following is an introduction to shock absorbers: Introduction 1: Shock absorbers are used to suppress the oscillation after the spring absorbs shock and rebounds, as well as impacts from the road surface. They are widely used in cars to accelerate the attenuation of the frame and body vibrations, thereby improving the vehicle's ride comfort. Introduction 2: When driving on uneven roads, although the shock-absorbing springs can filter out road vibrations, the springs themselves still have reciprocating motion. The shock absorber is used to suppress this spring jumping. If the shock absorber is too soft, the body will bounce up and down; if it is too hard, it will create excessive resistance, hindering the normal operation of the spring. Introduction 3: In the process of modifying the suspension system, a hard shock absorber should be matched with a hard spring, and the hardness of the spring is closely related to the weight of the car. Therefore, heavier cars generally use harder shock absorbers. The device connected to the vibration-damping crankshaft is used to counteract the torsional vibration of the crankshaft (i.e., the phenomenon where the crankshaft twists under the impact force of the cylinder ignition).

What does retired vehicle mean?

It refers to vehicles that have been retired from service. Owners who purchase used vehicles such as military retired vehicles, court-judged vehicles, auction vehicles, etc., should bring relevant certificates and procedures to the vehicle purchase tax collection and management department at the vehicle registration location to apply for the old vehicle tax payment procedures. For specific duration of use, inquire at the vehicle management office. More details about retired vehicles are as follows: Introduction 1: Vehicles are designated for retirement either because their service life has been very long, nearing the mandatory scrapping limit, or because the vehicle has major issues and can no longer be used normally, hence being retired. Therefore, there is no reason for such retired vehicles to be sold at high prices. Introduction 2: Both airport retired vehicles and retired taxis are scrapped after 8 years, with the scrapping time based on different vehicle models. Therefore, consumers should specifically check and understand how many years are left for the retired vehicle model before purchasing, otherwise, they might be required to scrap the vehicle shortly after purchase.

Can a motorcycle license plate be transferred to someone else?

Motorcycle license plates cannot be transferred to someone else. According to the Motor Vehicle Registration Regulations, when the ownership of a motor vehicle changes, the current owner must promptly apply for registration with the vehicle management office. The license plates for motor vehicles are issued by the Ministry of Public Security, so motorcycle license plates cannot be directly transferred to another person. The Motor Vehicle Registration Regulations provide the following details: Article 54: The types and styles of motor vehicle registration certificates, license plates, driving licenses, and inspection qualification marks, as well as the formats of various registration forms, are determined by the Ministry of Public Security. The motor vehicle registration certificate is uniformly printed by the Ministry of Public Security, and the production of motor vehicle registration certificates, license plates, driving licenses, and inspection qualification marks must comply with relevant standards. Article 43: After completing the transfer or cancellation of motor vehicle registration, the original owner can apply to the vehicle management office to use the original license plate number when registering a newly purchased motor vehicle.

Where is the tire pressure reset button on Wuling Hongguang S?

The tire pressure reset button of Wuling Hongguang S is located on the side of the gear lever. With the ignition switch turned on, press and hold the switch button until you hear a beep, indicating the reset is complete. Normal tire pressure: Generally, tire shops set the car tire pressure between 2.2-2.5, but it is often roughly estimated at 2.5. However, considering the physical effect of thermal expansion and contraction, tire pressure should be lower in summer, so 2.1-2.4 is more appropriate. In winter, tire pressure should be higher, so 2.3-2.6 is more suitable. Tire pressure monitoring: The system is a type of active safety equipment. It can alert the driver in time when there are signs of danger in the tires, prompting them to take appropriate measures, thereby avoiding serious accidents. With the tire pressure monitoring system, tires can always be kept working within the specified pressure and temperature range, reducing tire damage and extending tire lifespan.
