What are the hazards of automobile exhaust to humans?

Automobile exhaust poses the following hazards to humans: 1. Causes respiratory infections and leads to decreased lung function; 2. When concentration exceeds standards, it can cause poisoning symptoms; 3. Affects heart rhythm and may induce myocardial infarction; 4. Mild cases cause headaches, dizziness, and slowed reactions, while severe cases lead to decreased neurological function; 5. At certain concentrations, it can cause poisoning or even death. The main pollutants in automobile exhaust are carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide, lead compounds, benzopyrene, and solid particulate matter, which can cause photochemical smog. The CO, NOx, SOx, unburned hydrocarbons (HC), particulate matter (PM), and odorous gases emitted by vehicles pollute the air and pose significant hazards to humans, animals, and plants.

What is a Full-Size SUV?

Full-size SUVs, also known as large SUVs, are a category of SUVs characterized by their large dimensions, high displacement, and spacious interiors, typically with a body length close to or exceeding 5,000 millimeters. The engines of full-size SUVs are designed for high torque and low power, achieving performance through increased displacement without much consideration for fuel economy. The design of full-size SUVs prioritizes size and spaciousness in all aspects. If referring to full-size sedans, these usually denote models with a body length exceeding 5 meters, a width of 2 meters, and a wheelbase of 3.1 meters, such as flagship models from luxury brands like the Mercedes-Benz S-Class, BMW 7 Series, and Audi A8.

What Causes the Buzzing Sound When Accelerating the Engine?

It is because the engine oil has not fully lubricated all parts of the engine. After running for a period of time, the new engine oil can evenly lubricate all parts of the engine. It could also be due to severe wear and tear, followed by cleaning the internal parts of the engine. Below are the relevant explanations: 1. Engine system malfunction: Normally, a car operates smoothly and quietly, but when there is a malfunction in the fuel system or engine system, it can cause abnormal noises from the engine during acceleration. 2. Fuel line blockage: The fuel line blockage may be caused by the use of poor-quality fuel, requiring a switch to high-quality fuel. Generally, stepping hard on the accelerator can cause a large amount of fuel to spray out, providing power to the engine, but this should not be done frequently over the long term.

What are the pros and cons of engine start-stop?

Engine auto start-stop is a feature that automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving. Below is a detailed introduction to the advantages and disadvantages of engine auto start-stop: 1. Advantages: It can reduce unnecessary fuel consumption, lower emissions, and improve fuel economy. In urban traffic, when waiting for traffic lights or during congestion, it minimizes engine idling time. Additionally, after the engine shuts off, the electrical system can replace the belt pulley to power the engine cooling fan and the vehicle's air conditioning. 2. Disadvantages: It requires more durable starters and batteries. Conventional starter designs allow for high working currents but for short durations. Frequent use of the starter can easily lead to overheating and damage, so starters with auto start-stop functionality must be significantly more durable than standard starters. Moreover, the increased number of battery charge and discharge cycles can also affect battery lifespan.
