I previously drove a Changan CX20 that met the China IV emission standards, which was considered mainstream during its production era and significantly reduced exhaust pollution. I remember the salesperson specifically emphasized this when I bought the car because China IV had stricter requirements than the previous China III standard, with optimized engine control systems. Over the years, the fuel consumption wasn’t too high, and emissions tests passed smoothly during annual inspections. Although new cars now meet China VI standards, a well-maintained old CX20 can still run relatively cleanly in urban areas. It’s advisable to regularly inspect the exhaust pipe and catalytic converter to prolong their lifespan. If you notice any unusual odors or a drop in performance, visit a service station immediately—poor emissions not only affect air quality but also aren’t worth the long-term costs. Routine maintenance like oil changes and filter replacements shouldn’t be neglected, as keeping the car in good condition helps prevent issues. Overall, understanding your car’s emission standards can help you drive better and be more environmentally friendly.

When I bought the Changan CX20, the salesperson clearly stated it met China IV emission standards, and the vehicle registration certificate also indicated this. It drives smoothly, and I haven't seen any black smoke during long trips, which shows good emission control. Checking emissions is simple: just look at the environmental label on the windshield or search the model database online by entering the VIN. Pay attention to the engine sound while driving—if it runs smoothly without unusual noises, the emissions are usually up to standard. Don't slack on maintaining older cars; regularly cleaning the fuel injectors and intake pipes helps maintain emissions. Although China IV standards aren't as eco-friendly as newer models, they're better than some older China III standards, reducing smog formation and contributing a bit to society. Checking it yourself is beneficial, and making it a habit ensures a more worry-free drive.

The Changan CX20 typically meets the China IV emission standards, which was considered a step forward in environmental protection at the time. The standards limit harmful emissions such as hydrocarbons, and driving in the city doesn't feel particularly polluting, though it falls short compared to today's China VI vehicles. My daily maintenance focus is keeping the exhaust system clean to minimize negative impacts on the air—after all, we all breathe the same air. Regular maintenance ensures everything runs smoothly.

How to Bleed the Brakes of a Geely Emgrand EC7?

Bleeding steps: 1. The air bleeding operation requires two people to cooperate. After replacing or adding brake fluid, the air in the hydraulic pipeline should be bled. 2. One person continuously presses the brake pedal inside the vehicle to raise the pedal position and holds the brake pedal steady without loosening. Meanwhile, the other person underneath the vehicle loosens the bleeder valve to allow the air and brake fluid in the pipeline to be discharged together. 3. When the pedal position drops, immediately tighten the bleeder valve. Repeat this process several times until no air bubbles are discharged from the plastic tube. 4. Tighten the bleeder valve and reinstall the dust cover. Follow the above method to bleed the other wheel cylinders in sequence. During the bleeding process, check and replenish the brake fluid while discharging the air until all the air is completely expelled. 5. Then, add an adequate amount of the specified type of brake fluid to the reservoir.

What are the precursors of timing chain failure in Roewe 350?

Roewe 350 timing chain failure precursors include difficulty in ignition when starting the car in a cold state, or obvious "clicking" abnormal noise from the engine when stepping on the accelerator pedal. If you find that the car has difficulty in ignition or the engine noise is very loud, you should check whether the timing chain of the car is faulty in time. If so, the timing chain should be repaired or replaced in time. The following is the information about the timing chain: 1. The timing chain connects the timing wheel of the engine cylinder head and the crankshaft, and cooperates with a certain transmission ratio to ensure the accuracy of the intake and exhaust time. 2. The timing chain plays a "bridge" role in the engine. Driven by the crankshaft, it transmits kinetic energy to the corresponding parts, and keeps the pistons, valves and other parts in the correct position at different steps, so that the engine can operate normally.

How to Replace the Coolant in Zotye Damai X5 Radiator?

Steps to replace the coolant: 1. Open the engine hood and unscrew the radiator cap. 2. Turn on the drain valve at the bottom of the radiator to drain the existing fluid. After filling the radiator with coolant, start the engine to circulate the coolant in the radiator. 3. Once the operation is complete, inspect the entire radiator and pipelines for any leaks. If leaks are found, drain the coolant again, address the leakage issue, and then restart the process. Below is some information about coolant: 1. Coolant consists of 50% pure water, 40% methanol, and 10% other substances including dyes, corrosion inhibitors, and scale removers. 2. Compared to tap water, ethylene glycol is most notable for its antifreeze properties, whereas water cannot prevent freezing. Additionally, ethylene glycol has a high boiling point, low volatility, moderate viscosity that changes little with temperature, and excellent thermal stability. Therefore, ethylene glycol-based coolant is an ideal cooling solution.

Why does the car shake when starting cold in winter?

Cold start shaking in cars can be attributed to the following reasons: 1. Low temperature: The engine temperature is insufficient, and both fuel and lubricant temperatures are too low. During cold starts, additional fuel injection is required to meet power demands. Larger spark plug gaps result in smaller ignition energy. Poor fuel atomization at low temperatures demands higher ignition energy. Prolonged vehicle use can enlarge spark plug gaps, reducing ignition energy and consequently affecting power performance, leading to shaking. 2. Incorrect air-fuel mixture ratio: Inaccurate fuel-air mixture ratio occurs in both open-loop and closed-loop control systems. In closed-loop controlled vehicles, the oxygen sensor's minimum operating temperature is 370°C. If the exhaust pipe temperature hasn't reached 370°C upon startup, the oxygen sensor won't function. This causes the ECU to make incorrect judgments, leading to errors in controlling the fuel-air mixture and ignition timing through actuators, thereby reducing power output and causing shaking. 3. Faulty coolant temperature sensor: The coolant temperature sensor is crucial for the ECU to determine engine operating conditions. If the engine starts at -10°C but the ECU calculates fuel injection based on 20°C conditions, the insufficient fuel quantity will naturally cause shaking.
