The three-way catalytic converter is located at the front end of the engine exhaust pipe, between the front and rear oxygen sensors. Here is more information about the three-way catalytic converter: 1. The function of the three-way catalytic converter is to convert harmful gases such as CO (carbon monoxide), HC (hydrocarbons), and NOx (nitrogen oxides) emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Since this converter can simultaneously transform the three major harmful substances in exhaust gases into harmless substances, it is called a three-way catalytic converter. 2. After prolonged use, substances like carbon deposits in the exhaust can adhere to the porous ceramic substrate of the three-way catalytic converter, which may lead to clogging over time. If the three-way catalytic converter becomes clogged, cleaning is required to restore its optimal performance.

Can Power Banks Be Left in the Car?

Power banks should not be left in the car for extended periods. Here are the reasons why power banks should not be stored in vehicles: Battery: Power banks typically use lithium-ion batteries, which have relatively unstable chemical properties. Whether due to thermal expansion and contraction, self-discharge of battery cells, or impacts and drops, there is always a chance of issues arising at any time—though the probability is low, it's not worth the risk. High interior temperatures: Under direct sunlight, temperatures inside a closed vehicle can exceed 80°C, making battery explosions more likely in high heat. Health hazards: Prolonged storage of lithium-ion batteries can negatively impact human health.
