What is the function of the valve guide?

The function of the valve guide is to guide the movement of the valve, ensuring that the valve performs reciprocating linear motion, enabling the valve to correctly fit with the valve seat ring, and transferring the heat from the valve stem to the cylinder head. There are two types of valve guides: integral type and insert type. The integral valve guide directly processes the valve stem hole in the cylinder head; the insert type valve guide is press-fitted with a cylindrical tube into the guide hole in the cylinder head. The installation of the valve guide requires the inner and outer cylindrical surfaces of the valve guide to be processed and then pressed into the valve guide hole of the cylinder head or cylinder block. The inner hole is then precision reamed. To prevent axial rotation, a retaining ring positioning groove is provided, which cooperates with the positioning retaining ring to prevent the guide from moving and falling into the cylinder during operation. A small clearance is generally left between the valve stem and the valve guide to allow the valve stem to move freely in the guide.

Where is the appropriate place to put a car fire extinguisher?

It is more appropriate to place the car fire extinguisher in the armrest box, the luggage compartment of the passenger seat, or under the seat. The car fire extinguisher must be placed in a position that is easy to reach. If signs of spontaneous combustion are detected, you can quickly pick up the car fire extinguisher to extinguish the fire, thereby greatly reducing the severity of the spontaneous combustion. However, it should be noted that placing the car fire extinguisher in the trunk is definitely not advisable. In the event of a rear-end collision, the trunk may become stuck. If the car spontaneously combusts, it would be very difficult to open the trunk to retrieve the fire extinguisher. In addition, spontaneous combustion may cause the car's wiring to malfunction, making it impossible to open the trunk at all.

The international standard tire code represents the section width and aspect ratio in millimeters, followed by the tire type code, rim diameter, load index, and speed rating code.
