What are the reasons for excessive vehicle emissions?

Excessive vehicle emissions are caused by: 1. Aging of various vehicle components; 2. Use of low-quality fuel; 3. Failure of the three-way catalytic converter. The solutions for excessive vehicle emissions include: 1. Inspecting the three-way catalytic converter; 2. Using higher-quality fuel; 3. Replacing leaded gasoline with unleaded gasoline to reduce the emission of toxic substances in exhaust gases. The impacts of vehicle exhaust are: 1. Lead in the exhaust enters organs, disrupting the acid-base balance and causing lead poisoning; 2. Carbon monoxide in the exhaust hinders blood absorption and oxygen delivery, harming the human body and producing carcinogenic substances; 3. Inhalable particulate matter irritates the eyes and lungs, increasing the risk of respiratory diseases.

What Causes Engine Seizure?

Engine seizure is caused by: 1. Design flaws that cause the engine temperature to exceed its tolerable limit; 2. Poor quality or malfunctioning engine oil, leading to severe cooling issues; 3. Overuse resulting in excessive engine workload; 4. Inaccurate intake/exhaust system or ignition timing. Engine seizure occurs when the tachometer enters the red zone, where pistons expand due to overheating and get stuck in the cylinders, causing engine failure. In severe cases, excessive pressure with immobilized pistons may lock all four wheels and result in intense flames. Preventive measures include: 1. Applying glaze to the paint surface to protect it from direct exposure; 2. Parking in shaded areas to avoid prolonged sunlight exposure and opening the hood for ventilation and cooling.
