What is the normal tire pressure in psi?

Car tire pressure is normal between 33.5-36.3 psi. More information about car tire pressure is as follows: 1. The air pressure mark on the tire is usually on the side, indicating the maximum air pressure the tire can withstand; 2. The tire pressure monitor can monitor the tire pressure and temperature in real time and convey the tire information to the driver through the tire pressure display interface on the combination instrument. When the tire pressure is abnormal, the tire pressure alarm will be triggered. Of course, if the original car is not equipped with this function, it can be installed later, or a tire pressure gauge can be equipped to measure the tire pressure regularly; 3. The tire pressure values measured in cold tires and hot tires are different, with a difference of 0.3 bar between the two states. The manufacturer's recommended tire pressure marked in the car's user manual, the label next to the cab door (near the B-pillar), the drawer next to the driver's seat, and the small door of the fuel tank cap generally refers to the tire pressure value in the cold tire state.

What to Do If There Is Carbon Deposit in the Combustion Chamber?

If carbon deposits appear in the combustion chamber, it is recommended to use the walnut shell blasting method to remove them. Here is some information about automotive carbon deposits: 1. Causes: Carbon deposits are formed due to incomplete combustion of the fuel-air mixture in the engine. It is normal for carbon deposits to appear in the engine; any engine will develop carbon deposits over time. 2. Hazards: If carbon deposits accumulate in the combustion chamber, they can increase the compression ratio, leading to engine knocking during operation. Knocking can result in reduced engine power and increased fuel consumption.

How to Determine if a Catalytic Converter is Good or Bad?

Here are methods to determine if a catalytic converter is functioning properly: 1. Check if the voltage readings of the front and rear oxygen sensors are consistent. If they are the same, it indicates the catalytic converter is damaged—either clogged or burned out due to engine misfires. 2. Place your hand near the exhaust pipe to feel for airflow. If no airflow is detected, it signifies a blockage. 3. Remove the air filter. Rapidly press the accelerator while stationary; if black smoke emerges from the air filter, the catalytic converter is abnormal. 4. Measure the temperature difference before and after the catalytic converter to determine if it's clogged. 5. During a test drive, failure to reach maximum speed or poor acceleration performance.
