Directly check the vehicle's environmental protection label, which has clear markings on the back. For new vehicles, the emission standard can be found in the 'Emission Standard' column on the vehicle's factory certificate or vehicle conformity certificate. Log in to the public inquiry platform of the Motor Vehicle Environmental Protection Website (http://info.vecc.org.cn/ve/index) and enter the vehicle's VIN (Vehicle Identification Number) and the last 6 digits of the engine number to check the vehicle information. Owners can also inquire on the website of the Motor Vehicle Exhaust Pollution Supervision and Management Center. Bring the vehicle registration certificate (original or copy) to the DMV for inquiry. If you don't know specific vehicle information such as the engine number and other required details mentioned above, the official WeChat account also has a vehicle inquiry system. Enter the frame number to query. You can follow the steps below to inquire.

What to Do When You Can't See the Line in the Right Rearview Mirror During Curve Driving?

If you can't see the line on the right, look at the left rearview mirror and keep the car 50cm away from the left line. When you see the end of the left line, straighten the steering wheel. Here are some additional information: 1. Subject 2: Subject 2 is part of the motor vehicle driver's license assessment and refers to the field driving skill test. For small cars C1 and C2, the test items include reversing into a parking space, parallel parking, stopping and starting on a slope, turning at a right angle, and curve driving (commonly known as the S-curve) as five mandatory items (some regions also have a sixth item, high-speed card collection). 2. S-curve scoring criteria: For the S-curve and right-angle turns, as long as the tires do not press the line, no points will be deducted. Running over the curb will deduct 20 points; stopping midway will result in failure; stalling will deduct 20 points.

Do I Need to Go to the 4S Store Where I Bought the Car for Maintenance?

Maintenance does not have to be done at the 4S store where you bought the car. Since all brand 4S stores offer nationwide warranty services, you can go to any 4S store of the same brand for maintenance. Of course, you can also choose professional auto repair shops or general repair shops for car maintenance. The pros and cons of maintenance at 4S stores and outside are as follows: 1. Maintenance at 4S stores: The advantage of maintenance at 4S stores is that you will have a good maintenance record, which can increase the resale value of the car when selling it as a used car. The quality of parts is reliable, and if any quality issues arise during the warranty period, you can file a claim with the manufacturer. However, maintenance at 4S stores is generally more expensive, and some brands may require longer waiting times. 2. Maintenance outside: Professional auto repair shops. These shops have more authoritative technical expertise and do not charge miscellaneous fees. However, due to the high volume of vehicles, the waiting time may be longer. General repair shops. You can bring your own parts for replacement, which significantly reduces the cost. However, the source of parts at repair shops may not be reliable, and there is a risk of substandard parts being used.

At What RPM Does Driving Not Harm the Car

Engine speed in the range of 2000-4000 RPM allows for optimal engine utilization, which is referred to as the healthy RPM range. Both excessively low and high RPMs are detrimental. Too low RPM leads to incomplete fuel combustion, causing carbon buildup and engine damage, while too high RPM increases wear on engine cylinders and transmission gears, also harming the engine. Below are fuel-saving tips for daily driving: 1. Maintain steady speed: Most vehicles achieve optimal fuel efficiency at speeds between 60-90 km/h. Speeds significantly higher or lower than this range reduce fuel economy. At low speeds, piston movement is slow, leading to incomplete combustion. At high speeds, increased air intake velocity results in greater air resistance. 2. Control optimal RPM: For most fuel-injected vehicles, maintaining engine speed around 2200-2500 RPM during driving is most efficient. This RPM range provides the best fuel economy across all gears. 3. Manage shift RPM: When shifting gears, slightly increase throttle to raise RPM slightly above 2500. Shifting below 2000 RPM causes speed to drop post-shift, creating a lugging sensation that requires additional throttle input to compensate, ultimately wasting fuel. 4. Minimize unnecessary braking: Braking represents energy conversion and consumption. Anticipate situations like intersections, downhill sections, or potential hazards by lifting off the throttle early to reduce speed gradually, thereby decreasing the need for sudden braking.

What to Do When the Car's One-Button Start Has No Power?

The solution when the car's one-button start has no power is: You can use a jump start to get the car running. First, bring the two cars close enough so that the jumper cables can connect the positive and negative terminals of both batteries. Connect the positive end of the charging cable to the positive terminal of your car, and the other end to the positive terminal of the other car. Then, have the other car start its engine and rev the accelerator slightly. After that, try starting your own car. When the car battery runs out of power, you can also call your insurance company, as comprehensive car insurance typically includes provisions for roadside assistance in case of vehicle breakdowns.
