Comparative HS code duty analysis

Engine emission system failure (engine emission system failure,Comparative HS code duty analysis car owners need to deal with it in time) With the popularity of automobiles, environmental pollution has become one of the focuses of global attention, and the emission standards are also increasing Strict. Car owners are facing more and more frequent failures, one of the main problems is the failure of the engine emission system. This article will discuss the causes and consequences of engine emission system failures and how to deal with them in time. First of all, we need to understand the function of the engine emission system. The engine emission system mainly refers to the discharge of exhaust gas generated by engine combustion into the atmosphere after treatment. The main exhaust gas treatment devices include ternary catalysts, particle collectors, oxygen sensors, etc.When the engine emission system fails, the pollutant content of the vehicle exhaust will increase, which may cause serious consequences such as environmental pollution, vehicle performance degradation, and even fire. So, what is the reason for the failure of the engine emission system? Common reasons include the following points: I. Blocked or broken air filter: Blocked or broken air filter will cause insufficient air to enter the engine or be mixed with pollutants, so that the exhaust gas discharged does not meet the standard. II. Broken ternary catalyst: The ternary catalyst is the core component of the engine emission system, which can convert CO, NOx and HC in the exhaust gas into water and harmful substances. If the ternary catalyst fails, it will cause the exhaust gas to meet the standard. III. Damaged oxygen sensor: The oxygen sensor can detect the oxygen content in the exhaust gas, so as to adjust the amount of fuel injection and control the performance of the car.When the oxygen sensor is damaged, the pollutant content of the exhaust gas will increase. IV. Particulate collector failure: Particulate collector is an important component to remove particulate matter in the exhaust gas of diesel vehicles. The faulty particle collector will lead to an increase in particle emissions, making the car not meet the emission standards. The above points may lead to the failure of the engine emission system, so car owners should pay attention to regular replacement and maintenance in daily use. Finally, let's discuss the consequences of the failure of the engine emission system. If the faulty engine emission system is used for a long time, the car will face the following problems: I. The performance of the car declines: The faulty engine emission system will increase the emissions of the vehicle, reduce the power of the car, and even fail to start normally. II. Replacement of high-cost parts: such as ternary catalysts, etc., need to purchase high-cost parts for replacement.III. Environmental pollution: The increase in pollutants in the exhaust gas emitted by the faulty engine emission system will lead to environmental pollution and irreversible harm to human health. In a word, the failure of the engine emission system is a problem that car owners have to face. As for how to deal with it in a timely manner, car owners should regularly check and maintain, improve environmental protection awareness, and choose regular car repair shops or 4S shops for maintenance to ensure the long-term use of vehicles and environmental protection. In this context of global environmental protection and sustainable development, adapting to the trend of the times and dealing with engine emission system failures has become the inevitable responsibility of car owners.
