Car acceleration engine buzzing is due to insufficient lubrication of engine components by the oil. It takes some time for new oil to evenly lubricate all parts of the engine after running for a while; it could also be caused by severe wear and tear without proper cleaning of the engine internals. Normally, car driving is smooth and quiet, but when the fuel system or engine system malfunctions, it can lead to abnormal noises from the engine during acceleration. Fuel line blockage may occur due to the use of poor-quality fuel, necessitating a switch to high-quality fuel. Generally, slamming the accelerator can cause a large amount of fuel to spray out, providing the engine with power, but this practice should not be sustained long-term.

How to Identify the Symbols for National Emission Standards?

The method to identify the symbols for national emission standards is as follows: I1, II2, III3, IV4, V5, VI6. From National I to National VI, the emission standards vary at different stages. Under the new policy, vehicles meeting National IV standards and above can still legally operate on the road, while those below are only permitted in some cities. Currently, the latest National VI standard has seen significant upgrades compared to National V, hence it is divided into two phases: National VIa and National VIb. In the National VIb phase, most indicators are 50% stricter than National V standards. Implementing National VI can lead to a noticeable improvement of over 10% in urban air quality.

What to Do If a Beginner Driver Keeps Stalling When Starting the Car?

If a beginner driver keeps stalling when starting the car, they should first practice lifting the clutch pedal to find the engagement point, which is when the car is about to move (also known as the half-clutch state), and then hold it steady. Next, slowly release the clutch pedal, allowing the car to start smoothly. After that, practice coordinating the clutch and throttle. When lifting the clutch to the half-clutch state, hold it steady, and while slowly releasing the clutch, gently press the throttle to achieve a smooth start. If stopping on an uphill slope, make sure not to release the throttle with your right foot and maintain sufficient climbing power until reaching the chosen parking spot. When performing the stopping operation, both feet must coordinate well, and the entire sequence should be executed smoothly without delay. This means that as soon as the right foot releases the throttle, the left foot should quickly and accurately press the clutch pedal. When the car is about to stop, press the brake pedal to bring the car to a halt. Then, engage the handbrake firmly before releasing the foot brake.
