Is automobile exhaust carbon monoxide or carbon dioxide? How to deal with unqualified automobile exhaust?

The exhaust we are talking about now mostly refers to automobile exhaust, that is, the exhaust gas discharged from the exhaust pipe of the car. Automobile exhaust is another major factor in air pollution. Automobile exhaust contains carbon monoxide, nitrogen oxides and other solid particles that have adverse effects on the human body, especially leaded gasoline, which is more harmful to the human body. The main components of automobile exhaust are carbon monoxide, hydrocarbons, nitrogen oxides, carbon dioxide, sulfur dioxide, lead, and some particulate matter.

Is car exhaust carbon monoxide or carbon dioxide?

Automobile exhaust contains carbon monoxide and carbon dioxide. Automobile exhaust is the waste gas produced when a car is used, and contains hundreds of different compounds. Among the pollutants are solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides.

Carbon monoxide combines with hemoglobin in the blood 250 times faster than oxygen. Carbon monoxide enters the blood circulation through the respiratory tract, and the resulting carboxyhemoglobin weakens the blood's ability to transport oxygen to various tissues, harming the central nervous system.

Exhaust gas not only directly harms human health, but also has an impact on the environment. For example, sulfur dioxide in exhaust gas has a strong irritating odor, and when it reaches a certain concentration, it can easily lead to the occurrence of "acid rain", causing soil and water acidification.

What to do if car exhaust exceeds the standard

If the automobile exhaust exceeds the standard, the spark plug needs to be replaced. The spark plug is an important component of the gasoline engine ignition system. It can introduce high voltage electricity into the combustion chamber and make it jump over the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder. It is mainly composed of a wire nut, an insulator, a wire screw, a center electrode, a side electrode and a shell. The side electrode is welded to the shell.

Why does car exhaust smell so bad?

1. The car is not hot yet, so the three-way catalytic converter is not working properly. It will be fine after the car is warmed up.

2. The combustion is incomplete and the mixing ratio is not good.

3. The spark plug has carbon deposits or is burned.

4. The cylinder wire is leaking.

5. The oxygen sensor is not working properly, the intake system pressure is insufficient or the air intake is insufficient.

How to deal with unqualified automobile exhaust

1. Replace the spark plug and clean the fuel injector. The spark plug has insufficient ignition energy and cannot completely burn the mixed oil and gas, resulting in excessive HC content in the exhaust gas. In addition, the fuel injector has poor atomization and the mixed oil and gas is too concentrated, which may also cause the pollutants in the exhaust gas to be too high to pass the test. If you have not replaced the spark plug and fuel injector for a long time before the vehicle inspection, it is recommended that you replace them before the vehicle inspection to solve the problem.

2. Replace high-grade gasoline. Compared with low-grade gasoline, the advantages of high-grade gasoline are mainly reflected in "two highs and two lows": higher anti-knock and power, and lower harmful substances and exhaust pollution in gasoline. Using high-grade gasoline can pursue greater engine power and smaller displacement, and improve power and fuel economy. High-grade gasoline is cleaner, and the content of pollutants such as CO, NO, and HC produced after combustion will be greatly reduced.

3. Clean or replace the three-way catalytic converter. Exhaust gas is discharged through the exhaust pipe. The three-way catalytic converter on the exhaust pipe is the most important external purification device in the automobile exhaust system. It can convert harmful gases such as CO and HC discharged from automobile exhaust into harmless carbon dioxide, water and nitrogen. Long-term neglect of the maintenance of the three-ring catalytic converter will cause the three-ring catalytic converter to be blocked, the ability to convert harmful gases will decrease, and finally cause the exhaust gas emissions to fail to meet the standards. If there is a problem with the three-way catalytic converter, you can buy a special cleaning agent to clean it. If it is seriously blocked, you can choose to replace it directly.

4. Use economical and practical repair agents. When the vehicle is about to be inspected, use exhaust repair agents to clean and maintain the vehicle's oil circuit, thereby effectively reducing exhaust emissions. There are many such products on the market, and the effects vary. According to feedback from many car owners, Shimochi repair agents can effectively solve the problem of excessive exhaust gas. Many car owners have found that after using it, they can feel that the power has been improved, fuel consumption has been significantly reduced, and the exhaust gas is no longer unpleasant. There are also exhaust gas test reports from authoritative organizations. The report shows that the content of pollutants such as HC and NO in the exhaust gas of vehicles with Shimochi added can be reduced by 90%. The pollutants have been reduced so much, are you still afraid that the annual inspection will not be passed due to exhaust gas?
