👉 Transformer fumes, often associated with vintage or classic cars, are a mix of exhaust gases and combustion byproducts that accumulate inside the engine bay when the vehicle is not running. These fumes can include carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter, which are released during the engine's operation. The buildup of these pollutants can be particularly problematic in enclosed spaces like car trunks or garages, where ventilation is limited. Prolonged exposure to transanny fumes can lead to respiratory issues, headaches, and other health concerns, making it important for owners to ensure proper ventilation or consider air purifiers when the car is not in use.
