What can be extracted from a three-way catalytic converter?

A three-way catalytic converter can extract platinum (Pt), rhodium (Rh), and palladium (Pd), which are platinum group precious metals. The function of a three-way catalytic converter is to react with the exhaust gases emitted by a car, catalyzing or altering the nature of harmful emissions, thereby reducing their pollution. Methods for extracting precious metals from a three-way catalytic converter: Grind the catalyst inside the three-way catalytic converter into powder, as the precious metals are coated as a layer of catalyst inside; burn the powdered catalyst at high temperatures; add a sodium borohydride aqueous solution and boil to 100 degrees Celsius, then add a sodium chlorite hydrochloric acid solution; maintain the temperature around 100 degrees Celsius; after 3 hours, filter; add a 10% HCl aqueous solution for acid washing and water washing, keeping the temperature around 100 degrees Celsius. After separation, platinum group metals can be obtained. Precautions for using a three-way catalytic converter: Do not use leaded gasoline; avoid prolonged idling (open-loop control state); avoid sudden changes in engine speed; do not set the ignition timing too late; do not pull out the high-voltage wire for extended periods to test for sparks; when measuring cylinder pressure, disconnect the central control connector of the fuel pump to stop the injector from spraying fuel into the cylinder; if any cylinder is found to be malfunctioning, stop the vehicle promptly to inspect and rectify the issue, etc.

What is the reason for the buzzing noise from the seat belt in the car's B-pillar?

The reason for the buzzing noise from the seat belt in the car's B-pillar is the friction between the seat belt buckle and the seat. The solutions for the buzzing noise from the seat belt in the car's B-pillar are: 1. Adjust the height of the car seat and observe whether the noise disappears during the adjustment process; 2. Add a buffer material between the seat and the seat belt buckle. The correct way to fasten a car seat belt is: the shoulder strap should cross the chest, the waist belt should fit snugly against the hip bones, and the buckle should be securely fastened. The function of the car seat belt is: when the vehicle collides or emergency braking is applied, the pre-tensioning device will instantly retract, tightening the slack seat belt and firmly securing the occupant to the seat to prevent secondary collisions.

Should the ESP Vehicle Stability System Be Turned On?

ESP vehicle stability system should be turned on. The ESP system is a general term for systems or programs that enhance vehicle handling performance while effectively preventing loss of control when the vehicle reaches its dynamic limits. The ESP system includes functions such as electronic brake force distribution, anti-lock braking system, traction control system, and vehicle dynamic control system. The principle of the ESP system is as follows: through the ABS electronic control unit, based on signals from the wheel speed sensors, the electronic control unit calculates and analyzes to determine the wheel slip rate and vehicle speed. It then adjusts the wheel slip rate by controlling the throttle opening and brake pressure.
