Vehicles from 2004 comply with the China II emission standard. Here are several ways to check your vehicle's emission standard: 1. Check the environmental protection label issued during vehicle inspection. 2. Inquire about vehicle information at the vehicle management office. 3. Search the vehicle model directory on the Motor Vehicle Environmental Protection Website. The following are the implementation years of emission standards: 1. China I standard: Nationwide implementation on July 1, 2001, mainly targeting restrictions on carbon monoxide, hydrocarbons, and particulate emissions. 2. China II standard: Nationwide implementation on July 1, 2004, requiring a 30% reduction in carbon monoxide and a 55% reduction in hydrocarbons and carbon oxides. 3. China III standard: Nationwide implementation on July 1, 2007, requiring a 40% reduction in total pollutant emissions compared to China II. 4. China IV standard: Nationwide implementation on July 1, 2010, requiring a 50% to 60% reduction compared to China III. 5. China V standard: Nationwide implementation on January 1, 2018, requiring a 25% reduction in nitrogen oxide emissions compared to China IV. 6. China VI standard: China VIa nationwide implementation on July 1, 2020, and China VIb nationwide implementation on July 1, 2023.

What Problems Can Water-Damaged Cars Have?

The hazards of water-damaged cars are extremely severe. If a vehicle is submerged in water, it can easily cause rusting of body components, shortening its service life and reducing safety performance. The problems caused by water-damaged cars are as follows: 1. Water-damaged cars can lead to corrosion and rusting of the vehicle's wiring, causing the vehicle to suddenly stall or spontaneously combust due to short circuits while driving, with unimaginable consequences. Additionally, the repair costs for water-damaged vehicles are very high, with repairs for severely water-damaged vehicles typically costing over 50% of the car's value, and insurance claims can be very difficult. 2. There are many channels in a car, and once water enters, it is very difficult to clean, leading to rust over time. The lubricants in components like the four-wheel bearings and half-shafts can deteriorate quickly when soaked in water. Electronic devices in the car, such as the electronic parking brake, audio system, and various sensors, can leave hidden dangers if not repaired promptly after being water-damaged. The most severe case is the engine; after a car has been waterlogged, never attempt to start or turn the engine, as this can cause severe deformation of the engine connecting rods.

What Happens If You Block the Car's Exhaust Pipe?

Blocking the car's exhaust pipe will prevent the car from starting. Here's a detailed explanation: 1. The engine operates in four steps (intake → compression → power → exhaust). When the exhaust is blocked, the intake phase of the next cycle is also hindered, causing the engine to stall. 2. If the pipe isn't completely blocked, starting the engine may not be an issue, but acceleration could become sluggish. Additionally, some engines may increase fuel injection to prevent stalling or boost power, leading to incomplete fuel combustion. This not only negatively impacts fuel efficiency but can also cause severe carbon buildup over time.
