I live in Beijing, and since last year, all new cars sold must meet the China VI emission standard. Major cities like Shanghai, Tianjin, and Chongqing implemented the same regulation simultaneously. In provinces such as Guangdong (including Guangzhou and Shenzhen), Jiangsu, and Hebei, all 4S stores are required to sell only China VI-compliant vehicles. Some areas are even stricter—Shenzhen enforced this standard back in 2019. Now, the standard is unified nationwide, but if you plan to buy a car from another region, it's best to check local policies. That said, China VI vehicles indeed have better exhaust treatment and are more environmentally friendly to drive.

What Are the Reasons for Difficulty in Acceleration in Automatic Transmission Cars?

Automatic transmission cars may experience difficulty in acceleration due to engine malfunctions, transmission failures, or excessively dirty components. Below are the specific causes and solutions for acceleration difficulties in automatic transmission cars: Specific causes of acceleration difficulties in automatic transmission cars: Engine malfunction: Park the car on level ground, place the transmission lever in the P position, engage the handbrake, and press the accelerator pedal to check the engine's acceleration performance. If the engine speed increases slowly or fails to rise beyond a certain point, the issue may stem from the engine. Inspect the engine's fuel supply pressure, cylinder pressure, the proper functioning of the fuel injection system, and the sensors. Transmission failure: This could be due to severely worn or burnt friction plates inside the transmission, or malfunctions in the transmission valve body's shift valves, solenoid valves, transmission control computer, and related circuits, leading to difficulties in upshifting and acceleration. Solutions for acceleration difficulties in automatic transmission cars: Use an automotive diagnostic computer to check for any fault codes; resolving these faults can fix the issue. Inspect the vehicle's spark plugs for erosion and replace them promptly if damaged. Check the cleanliness of the vehicle's air filter and throttle body; excessive dirt can cause inaccurate throttle position signals, necessitating cleaning of the air filter and throttle body.

Should You Shift to Neutral (N) When Stopping at a Red Light in an Automatic Car?

When stopping at a red light in an automatic car, it is advisable to shift to Neutral (N). Different approaches should be taken depending on the duration of the red light. Below are the recommended actions for automatic cars encountering red lights of varying durations, as well as the method for parking an automatic car: Recommended actions for automatic cars encountering red lights of varying durations: When encountering a brief red light at an intersection, simply press and hold the brake pedal. If the stopping time exceeds 2 minutes, shift to Neutral (N) to protect the transmission and prevent the transmission fluid from overheating. If the stopping time exceeds 5 minutes, it is best to turn off the engine and shift to Park (P), which is both environmentally friendly and fuel-efficient. Not all automatic cars require gear shifting when waiting at a red light. For example, vehicles equipped with an electronic parking brake or auto start-stop system will automatically engage parking or turn off the engine after the car comes to a complete stop and the brake pedal is pressed for a few seconds. Method for parking an automatic car: First, press the foot brake to bring the car to a complete stop, then shift the gear from Drive (D) to Neutral (N) and engage the handbrake. Release the foot brake but do not turn off the power, then press the foot brake again and shift the gear from Neutral (N) to Park (P). Finally, release the foot brake and turn off the power.

Are the engines of the new Vito and V260 the same?

The engines of the new Vito and V260 are the same, both with 211 horsepower. Classification of engines: Depending on the power source, automotive engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others. Principle of engines: Common gasoline and diesel engines are both reciprocating piston internal combustion engines, which convert the chemical energy of fuel into the mechanical energy of piston movement to output power. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easier to start, and have lower manufacturing costs; diesel engines have higher compression ratios, better thermal efficiency, and superior economic and emission performance compared to gasoline engines.

What gear should an automatic transmission car use when going down a long slope?

When an automatic transmission car is going down a long slope, if it is a manual-automatic integrated car, you can shift into D+ gear or D2 gear for descending. For a purely automatic car, you can shift into L1 or L2 gear for descending. This is because when the car is in a low gear, it keeps the output of the transmission at a low speed, which effectively ensures the car descends safely and reduces wear or damage to the car's braking system. Precautions for driving downhill: Decelerate when going downhill: Before descending, the vehicle should slow down in advance and shift into a low gear when entering the downhill section. This ensures safe driving on the downhill section, reduces the frequency of using the brakes, and avoids situations where the braking system overheats and fails. Do not coast in neutral: When driving downhill, never coast in neutral. Always use an appropriate gear to utilize the engine's braking effect to reduce the vehicle's speed. Coasting in neutral can cause the vehicle to speed up, increase the burden on the braking system, and may even lead to brake failure. Maintain a safe distance from the vehicle ahead: When driving downhill, if there is a vehicle in front, always maintain a safe distance. If you follow too closely, you may not be able to take emergency measures in time if an unexpected situation arises ahead.

Which gear should be used for automatic transmission when going uphill or downhill?

Automatic transmission vehicles should use the L gear when going uphill or downhill. The L gear is a low-speed gear. When engaged, the transmission will maintain a lower gear without upshifting, thereby increasing wheel torque. Below is an introduction to car gears: Generally, automatic transmission vehicles have six gear positions: L gear, B gear, P gear, R gear, N gear, D gear, and S gear. The L gear is the low-speed gear. When climbing a slope, engaging this gear will maintain a high RPM and low gear state. The B gear is the braking gear. When driving on a long downhill section, engaging the B gear will activate engine braking, which helps prevent accidents caused by overheating of the brake pads due to prolonged use of the service brake. The P gear is the parking gear. When parking, the gear should be placed in P, which will stop the vehicle and prevent it from rolling. The R gear is the reverse gear. It should be used when reversing the vehicle, but it can only be engaged when the vehicle is completely stopped. Otherwise, it may cause severe damage to the transmission. The N gear is the neutral gear, used for brief stops, such as waiting at a traffic light. The D gear is the drive gear, used when the vehicle is moving forward. The S gear is the sport mode. The transmission will freely shift gears based on the current speed and the driver's throttle input, but there may be a slight delay during gear shifts.

Which gear should be used for climbing a long slope with an automatic transmission?

When climbing a long slope with an automatic transmission, you should use the L gear. The L gear is the low gear. After shifting into this gear, the transmission will maintain a lower gear without upshifting, thereby increasing the torque at the wheels and allowing the vehicle to climb the slope smoothly. Here is an introduction to the gears of a car: Generally, automatic transmission cars have gears such as L, B, P, R, N, D, and S. The L gear is the low gear. When climbing a slope, shifting into this gear will keep the engine at high RPM and low gear. The B gear is the brake gear. When driving on a long downhill slope, you can shift into the B gear, at which point engine braking will engage, helping to avoid accidents caused by overheating of the brake pads due to prolonged use of the service brake. The P gear is the parking gear. When parking, the gear should be placed in P, which will stop the vehicle and prevent it from rolling. The R gear is the reverse gear. Use the R gear when reversing the vehicle, but only when the vehicle is completely stopped. Otherwise, it can cause serious damage to the car's transmission. The N gear is the neutral gear, used for short stops, such as when waiting at a traffic light. The D gear is the drive gear, used when the vehicle is moving forward. The S gear is the sport mode. The transmission will freely shift gears based on the current speed and the driver's throttle input, but there will be a slight delay during shifting.
