What is the function of the valve train?

The function of the valve train is to open and close the intake and exhaust valves of each cylinder in accordance with the working cycle and firing order of the engine, ensuring that fresh charge enters the cylinder in a timely manner and exhaust gases are expelled promptly. During the compression and expansion strokes, it ensures the sealing of the combustion chamber. For gasoline engines, the fresh charge is a mixture of gasoline and air, while for diesel engines, it is pure air. The degree to which the fresh mixture or air fills the cylinder is indicated by the volumetric efficiency. The higher the volumetric efficiency, the greater the mass of fresh air or combustible mixture entering the cylinder, the more heat the combustion mixture can generate, and the greater the engine's power output. For an engine of a given displacement, the mass of the charge is related to the temperature (T) and pressure (P) at the end of the intake stroke. The lower the intake temperature and pressure, the greater the mass of the intake charge and the higher the volumetric efficiency.

What does traffic light B mean?

Traffic light B refers to the traffic light used for Bus Rapid Transit (BRT), which is specifically designed for BRT systems. Its function is the same as regular traffic lights, generally consisting of red, green, and yellow lights. A red light indicates stop, a green light indicates permission to proceed, and a yellow light serves as a warning. Traffic light B is specifically for buses. When the B light turns green, buses can proceed along their designated route regardless of other lights. When the B light turns red, buses must stop and yield regardless of other lights. There are two types of traffic lights: those for motor vehicles, commonly referred to as vehicle traffic lights, typically composed of red, yellow, and green lights to direct traffic flow.

Why Do You Need to Blip the Throttle When Downshifting?

Bliping the throttle during downshifting helps eliminate the speed difference between the engine and the transmission. While maintaining the same vehicle speed, the engine needs to provide a higher RPM to achieve the appropriate torque for engaging a larger gear, ensuring the engine speed and gear position are as synchronized as possible. This minimizes the jerky feeling during downshifting. Bliping the throttle during downshifting involves pressing the clutch with your left foot while simultaneously giving a quick throttle blip with your right foot to increase the RPM. It can also be understood as pressing both the throttle and the clutch at the same time, allowing the clutch to operate more smoothly, extending its lifespan, and improving the driving experience. It's important not to blip the throttle too much during downshifting, meaning you shouldn't press the throttle too hard. Excessively high engine RPM can cause the car to lurch forward. Downshift throttle blipping is a driving technique that requires practice to master the method of smooth downshifting. If the vehicle speed and gear position don't match, the meshing of gears during shifting can cause vibrations, resulting in a jerky feeling.

Does driving over potholes cause significant damage to the car?

Driving over potholes has minimal impact on the car. Below are the effects of driving over potholes on the vehicle: 1. Tires and rims: When a car suddenly passes over uneven road surfaces at high speed, the wheels bear the greatest impact force. If the speed is too high, it can directly cause tire blowouts, and in severe cases, even lead to rim deformation. If you accidentally drive over a large pothole, be sure to check the condition of the wheels promptly under safe conditions. 2. Suspension system: Generally, after passing over large potholes, not only the wheels but also the suspension system may be affected. If no significant damage is found on the tires and rims, it means the impact force has been absorbed by the suspension. Long-term driving over potholes can cause considerable damage to the suspension and shock absorbers, so it's best to avoid potholes whenever possible.
