How to deal with large engine exhaust gas
With the increasing awareness of environmental protection and the increasing number of automobiles, the issue of engine exhaust gas emissions has attracted increasing attention. Excessive exhaust gas emissions not only cause pollution to the environment, but may also affect the performance and life of the engine. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the causes and treatment methods of large engine exhaust gas.
1. Common causes of large engine exhaust gas
Excessive engine exhaust emissions are usually caused by the following reasons:
| Reason | Specific performance |
|---|---|
| Insufficient fuel combustion | Mixture is too rich or too lean, ignition system failure |
| engine wear | Piston ring wear, cylinder wall wear |
| Three-way catalytic converter failure | Decreased catalytic efficiency and clogging |
| EGR system failure | Valve stuck, pipeline blocked |
| air filter clogged | Poor air intake leads to poor combustion |
2. How to deal with large engine exhaust gas
For different major causes of exhaust gas, the following treatment measures can be taken:
| Question type | Treatment method | Things to note |
|---|---|---|
| fuel system problems | Clean the fuel injectors and replace the fuel filter | Use high quality fuel |
| Ignition system problems | Check spark plugs, high-voltage wires, and ignition coils | Replace spark plugs regularly |
| Engine mechanical wear | Overhaul engine, replace piston rings | Professional maintenance agency processing |
| Exhaust system problems | Clean or replace the three-way catalytic converter | Use regular accessories |
| EGR system failure | Clean EGR valve and pipeline | Avoid using low-quality engine oil |
3. Measures to prevent excessive engine exhaust gas
In addition to promptly dealing with existing problems, it is equally important to do preventive work:
1.Regular maintenance: Carry out maintenance strictly in accordance with the maintenance intervals recommended by the manufacturer, including replacement of engine oil, engine filter, air filter, etc.
2.Use high quality oil: Choose fuel and oil that meet engine requirements and avoid using inferior oil.
3.Avoid prolonged idling: Long-term idling will lead to incomplete combustion and increase exhaust emissions.
4.Check your emissions system regularly: Especially for vehicles with a long service life, the working status of the three-way catalytic converter and oxygen sensor must be checked regularly.
5.Develop good driving habits: Drive smoothly, avoid rapid acceleration and deceleration, and help reduce exhaust emissions.
4. Popular technologies related to waste gas treatment
According to recent Internet hot spots, the following exhaust gas treatment technologies have received widespread attention:
| Technical name | Principle | Applicable models |
|---|---|---|
| GPF particle trap | Physically filter particulate matter | National VI and above gasoline vehicles |
| SCR selective catalytic reduction | Urea solution to treat nitrogen oxides | Diesel car |
| DPF Diesel Particulate Filter | high temperature combustion particulate matter | Diesel car |
| 48V light hybrid system | Reduce engine load | Hybrid model |
5. Common misunderstandings about waste gas treatment
When dealing with engine exhaust problems, car owners often have the following misunderstandings:
1.Ignore the fault light: When the engine check light comes on, many car owners choose to ignore it, which may cause the exhaust problem to worsen.
2.Blind use of additives: Some car owners rely too much on fuel additives and ignore the maintenance of mechanical faults.
3.Cheap repairs: Choosing irregular maintenance points for exhaust gas system maintenance may lead to secondary pollution.
4.Ignore the warm-up phase: Driving at high speed without proper preheating when the car is cold will increase exhaust emissions.
5.Overreliance on shielding: "Solving" the exhaust gas problem by shielding oxygen sensors and other methods is actually deceiving others.
Conclusion
Excessive engine exhaust gas is not only an environmental problem, but also an important indicator of engine health. By promptly diagnosing the cause, taking corrective measures, and developing good vehicle habits, exhaust emissions can be effectively controlled and reduced. As emission regulations become increasingly stringent and technology advances, exhaust gas treatment has become an important part of car maintenance. It is recommended that car owners conduct regular emission tests to ensure that their cars meet environmental requirements while maintaining optimal performance.
