CVVL engine refers to an engine that adopts Continuous Variable Valve Lift technology. Here are the relevant details: 1. Classification by control effect: Variable valve lift technology can be divided into Continuous Variable Valve Lift (CVVL) and Discrete Variable Valve Lift (DVVL). Traditional gasoline engines have fixed, non-variable valve lift. 2. Valve lift in traditional gasoline engines: The cam profile design is a balanced choice for the engine under all operating conditions. As a result, the engine neither achieves optimal high-speed efficiency nor optimal low-speed torque.

How to reference points for roadside parking in rainy weather during Subject 3 test?

When receiving the instruction to pull over, immediately turn on the right turn signal and reduce speed (if the speed is too high, apply brakes and shift to a lower gear; if the speed is moderate, just use clutch and brake for control). Here are the relevant details: Observation: Simultaneously check the right side mirror and the right rear of the vehicle for any vehicles or pedestrians that need to be avoided. Once the right side and rear are clear, slightly steer right (while gently applying brakes and fully depressing the clutch), align the driver's position toward the center of the road, then make minor right adjustments until the front 1/3 of the vehicle overlaps with the right lane edge line. Straighten the vehicle body and gradually brake when approximately 30cm from the roadside or boundary line to bring the vehicle to a stop. Note: If there are intersections, bus stops, or no-parking signs ahead, you should proceed past these areas before stopping.

What Causes Fogging on the Outside of Car Windows in Summer?

In summer, car windows fog up due to the low temperature setting of the air conditioning inside the car, which creates a significant temperature difference. The interior of the car is cooler, while the outside temperature is higher. When the hot outside air comes into contact with the cold glass, the water vapor in the outside air condenses into tiny droplets on the cold glass, forming what we commonly refer to as fog. Reasons for car window fogging in summer: The cold air blown out by the AC lowers the temperature of the glass area significantly. When this cold glass encounters the warmer outside air, especially in conditions of high humidity, it easily forms a layer of fog on the outside. Using the AC to remove fog: For manual AC models, simply turn the fan speed to the maximum, turn on the AC's A/C switch, set the temperature to the lowest, and press the front window defogging button. You will see the fog on the windows gradually dissipate. For automatic AC models, press the AUTO button, set the temperature to the lowest, and press the front window defogging button. For models equipped with rear window heating and defogging functions, pressing the rear window defogging button can speed up the defogging process and help prevent fog from forming again. Using professional defogging agents: Before applying the defogging agent, clean the inside of the windshield thoroughly. Spray an appropriate amount of the defogging agent, let it dry, and then wipe it off with a clean towel. The defogging agent creates a hydrophobic layer between water molecules and the inner surface of the glass, keeping the glass surface clean and preventing fog formation.
